Be sure to watch for an increase in aphid populations, especially in seedling stage cucumbers and pickles. Populations are increasing as a result of the cool, wet weather. If the weather turns hot, you can expect to see aphid explosions since beneficials may not be able to keep up. A treatment should be applied if 20% of the plants are infested and before significant leaf curling occurs. Lannate or Thiodan should be used.



At the present time, all peppers that have fruit ½ inch in size or larger should be sprayed on a 7 day schedule for corn borer, corn earworm and pepper maggot control. In the Milford, Harrington, and Frederica areas, sprays should be applied on a 5-7 day schedule. Since corn earworm catches exceed 20 per night in those areas, a corn earworm spray is also needed. Since acephate (Orthene or Address) does not provide effective earworm control, Lannate or a pyrethroid should be used. In all other areas, acephate can still be used on a 7-day schedule. Lannate, Spintor, or a pyrethroid should be used on a 5-7 day schedule. We are also starting to see an increase in aphid populations in peppers. Remember a continuous pyrethroid program should not be used to avoid aphid explosions.


Lima Beans.

Continue to watch for economic levels of leafhoppers that can still be found in fields throughout the state. Remember, most labeled insecticides will only provide 7-10 days of control.  In fields with pin pods, you should sample for earworm, lygus and stinkbugs. We have just found our first corn earworm larvae in lima beans in the Georgetown area. A treatment should be applied if you find one corn earworm per 6 foot of row or 15 tarnished plant bugs and/or stinkbugs per 50 sweeps. Lannate or Capture can be used to control all 3 insects on lima beans.


Snap Beans.

Processing snap beans should be sprayed at the bud and pin stages with acephate for corn borer control except in the Milford , Harrington and Frederica areas where Capture or Asana should be added to the mix for corn earworm control. A third spray with Capture or Lannate will be needed 5-7 days from harvest except in the Dover, Milford, Harrington, Frederica and Wyoming areas where you will need 2 sprays between pin and harvest.  Fresh market snap beans should be sprayed on a 7-day schedule as soon as pin pods are present.


Sweet Corn.

All fresh market silking sweet corn should be sprayed on a 3-day schedule except in the Milford, Frederica and Harrington areas where sprays are needed on a 2-day schedule. Watch for aphid populations that are increasing on the tassels and silks. Although this feeding does not cause a direct yield loss, it can result in quality problems. A combination of Lannate plus a pyrethroid will help to reduce aphid populations. In areas where corn earworm moth catches are high or populations are increasing, you should not use Lannate alone.

Late Blight Update -  Bob Mulrooney, Extension Plant Pathologist; bobmul@udel.edu


Disease Severity Value (DSV) Accumulations as of August 3, 2000 are as follows:

Remember that 18 DSV’s is the threshold to begin a spray program








April 27


7-day, high rate

May 20


7-day, high rate

May 24


7-day, high rate


Accumulated 15 DSV’s since the last report.


This will be the last Late Blight Update for the 2000 season. Since many early plantings are maturing and there is no late blight present in the area, spraying is probably not justified. Later plantings that are still growing should be protected at this time. The weather continues to be very favorable for foliage and tuber diseases.


Fortunately Delaware and New Jersey were late blight free once again. To our north I have had reports of late blight on tomatoes in PA and NY.


I just finished harvesting a fungicide test for pink rot control conducted here at the University farm in Newark. I will be sharing that information with you as soon as the data collection is complete. We had plenty of disease on our inoculated plots on Russet Norkotahs.




Vegetable Diseases -  Kate Everts, Extension Vegetable Pathologist, University of Delaware and University of Maryland;  everts@udel.edu



Powdery Mildew – Powdery mildew is present throughout our area on susceptible cucurbits.  Fortunately new fungicides have been registered for control of powdery mildew, recently.  An excellent article was written by Drs. Meg McGrath and Tom Zitter on fungicide recommendations for powdery mildew and resistance management.  The following is excerpted from that article.


Managing fungicide resistance is a critical aspect of managing powdery mildew with fungicides.  Fungicides that are systemic or have translaminar activity are needed to obtain adequate protection of the underleaf surfaces, where conditions are more favorable for development of the pathogen than on upper surfaces.  Unfortunately, systemic fungicides are generally at-risk for resistance development because they have a specific mode of action (single site of activity), and powdery mildew fungi have exhibited a high potential for resistance development.  This has been especially true of the cucurbit powdery mildew fungus, which has developed resistance to Benlate (benomyl), Topsin M (thiophanate-methyl), and Bayleton (triadimefon) in a short period of time.


Current recommendations for managing powdery mildew and fungicide resistance include using a diversity of fungicides.  Fortunately, three new fungicides have been registered for use in the U.S. since March 1999 and two more are being reviewed by EPA.  These three new fungicides are the strobilurin fungicides Quadris (azoxystrobin, Zeneca) and Flint (trifloxystrobin, Novartis) and the DMI fungicide Nova (myclobutanil, Rohm & Haas).  Unfortunately, these new fungicides have a high risk for resistance development; thus it is imperative to use them in a fungicide program designed to manage resistance.  A high level of resistance to strobilurin fungicides developed within two years in other countries where these fungicides were used exclusively.  Although Nova is much more effective than Bayleton, these fungicides are in the same fungicide class.  As a result, strains of the powdery mildew fungus that are fully resistant to Bayleton (e.g. cannot be controlled by Bayleton) are less sensitive to Nova than strains that are sensitive to Bayleton.


The fungicide program recommended for cucurbits (powdery mildew) in 2000 is a strobilurin fungicide (Quadris or Flint) applied in alternation with Nova tank mixed with a contact fungicide on a 7-day schedule. …The first spray should be applied at the IPM threshold (1 of 50 leaves with symptoms) or before symptoms when fruit are starting to enlarge.  One major change from the program recommended in 1999 is to begin with a strobilurin fungicide.


Several multi-site contact fungicides are registered for use on cucurbits.  Chlorothalonil (Bravo, Echo, etc.) fungicides and copper fungicides (Basicop, Champ, Kocide, etc.) are also effective for diseases other than powdery mildew.  Sulfur (Microthiol special, Micro Sulf, etc.), potassium bicarbonate (Armicarb 100), monopotassium phosphate (Nutrol), mineral oil (JMS Stylet-oil, SunSpray Ultra-Fine, etc.), and biofungicides (AQ10) are only effective for powdery mildew.


Nova is registered for powdery mildew at a rate of 2.5 to 5.0 oz./A.  The lower (2.5 oz.) rate has performed well here on the Delmarva peninsula, however, in New York the higher rate was necessary for good control.  I continue to recommend the 2.5 oz. rate until we observe resistance at the field level. 


Another consideration is that no more than four strobilurin sprays (Flint or Quadris) should be applied to a crop in one season. Finally, remember that Quadris is highly phytotoxic to certain apple varieties.




Developing a spray program for foliar diseases of pumpkins is difficult because many diseases (some controlled by different fungicides) must be considered.  The following is a schedule that is designed to be effective and take economics into consideration.  The core of the program is broad spectrum products, maneb, chlorothalonil, and Quadris.  This program will control most diseases of pumpkin, but it is still necessary to scout for development of powdery mildew and downy mildew. 


Early in the season, when disease pressure is low and the plant canopy is relatively open, apply Maneb 75DF 2.0 lb/A.  When disease pressure begins to build up, or powdery mildew is observed (threshold of one lesion on 45 old leaves), switch to an alternation of fungicides.  Begin with an application of Flint (1.5 –2.0 fl.oz./A) or Quadris (12 oz./A) plus copper (such as Kocide DF 1.5 lb/A).  Alternate with chlorothalonil (such as Bravo Ultrex 2.7 lb/A or Terranil 3 pt 6L/A) plus copper plus Nova (2.5 oz./A).  


These fungicides should be applied at regular intervals depending on the susceptibility of the pumpkin variety and the weather.  Our preliminary data indicate that maximum yield on susceptible varieties can be achieved only with weekly sprays.  However for varieties with some tolerance to powdery mildew (such as Magic Lantern or Merlin) grown on a cover crop (which reduces black rot pressure) a 10 to 14 day schedule does a good job of controlling diseases.


Downy Mildew on Cucurbits.

Downy mildew on cucurbits is not usually present here on the Delmarva peninsula until very late in the season (mid- August or September).  This is because the fungus that causes downy mildew cannot survive here and must spread from south to north by airborne spores.  Symptoms of downy mildew on cucurbits begin as angular yellow or chlorotic areas on the upper surface of leaves.  Sporulation occurs on the underside of leaves and appears as brown to gray.  The sporangia can be seen with a 10X hand lens and appear as barely distinguishable black or purple spots. To determine when to begin spraying, scout your field for the presence of downy mildew.  In addition to scouting, forecasts or early warning of potential appearance of downy mildew is available on a web site from NCSU.  The web site uses information on known disease outbreaks and atmospheric conditions (air pathways or “trajectories”, likelihood of spore survival, rainfall and weather conditions favorable for disease development) to forecast new disease outbreaks.  Currently the closest confirmed outbreak is in North Carolina.  However, weather is favorable for downy mildew development and the forecast is recommending that growers in our region remain alert for presence of downy mildew during and after this period of disease-favorable weather.  To follow the progress of downy mildew in the southern U.S. and view forecasts, visit www.ces.ncsu.edu/depts/pp/cucurbit/ . When you observe this disease, apply Ridomil Gold/Bravo or Ridomil Gold /Copper in alternation with chlorothalonil or Quadris


Pickling Cucumbers.

Phytophthora fruit rot is a disease that can infect all cucurbit fruit including pickling cucumbers.  Fruit rot is a different phase of crown and root rot, all caused by Phytophthora capsici and other Phytophthora spp.  The symptoms are initially large water soaked lesions which develop a white dense growth on the fruit. The disease can spread rapidly and fruit collapse.  This continues after harvest.  Like the crown and root rot phase, high soil moisture (typically standing water) for two days allows the sporangia to form and release zoospores.  Secondary infections then occur.  Infection can also occur in fall pickles following a spring crop which was under standing water. 


Water management is critical to reducing damage from this disease.  Avoid planting susceptible crops in low lying areas where standing water is common.  Plant on raised beds and subsoil between crops to avoid layers that are impervious to water.  A three year rotation is important.  Crops to avoid in the rotation are all cucurbits (including melon, watermelon, squash and pumpkin) and pepper, tomato and eggplant.


Gummy Stem Blight.

Weather conditions are excellent for spread of gummy stem blight on watermelon.  Continue to apply Quadris (11-15.4 oz./A) alternated with chlorothalonil on a 7-day interval or according to the MELCAST program for watermelons.   This fungicide combination has consistently given the best results in research trials in Delaware and Maryland. 


White Mold on Lima and Snap Bean.

Recent weather has been very favorable for the development of the fungus that causes white mold on lima and snap beans. A fungicide should be applied if the soil has been wet for 6-10 days before bloom. The first spray should be applied when 70-80% of plants have open blossoms.  A second spray should be applied 5-6 days later.  Benlate, Rovral and Topsin M are registered on lima and snap beans and Ronilan is labeled for use on snap beans only.  For lima beans the PHI’s are 28 days for Benlate, 14 days for Topsin M, and 0 days for Rovral.  In snap beans the PHI’s are 14 days for Benlate and Topsin M, 0 days for Rovral and 10 days for Ronilan.

The first fungicide spray should be applied when the watermelon vines meet within the row.  Additional sprays should be applied using MELCAST.  Accumulate EFI (environmental favorability index) values beginning the day after your first fungicide spray.  Apply a fungicide spray when 30 EFI values have accumulated by the weather station nearest your fields.  Add 2 points for every overhead irrigation.  After a fungicide spray, reset  your counter to 0 and start over.  If a spray  has not been applied in 14 days, apply a fungicide and reset the counter to 0 and start over.  The first and last day listed above can be partial days so use the larger EFI value of this report and other reports for any specific day.


  If, for some reason, a serious disease outbreak occurs in your field, return to a weekly spray schedule.

Corn Earworm Populations in 2000.

After last seasons’ record level earworm populations, we did see higher than normal levels of earworm moths in some pheromone traps in Virginia, Maryland and Delaware. However, it appears that these populations did not cause significant damage in early vegetables, probably due to weather factors. Virginia has just completed their survey of field corn, which they use to predict the potential for earworm populations in soybeans. In general, their results indicate that levels are lower than in the past. We have just started to conduct our survey and we are seeing infestation levels ranging from 2 to 20% infested ears. Last year we found 80 –100% infested ears. Entomologists in the region agree that these results in combinations with the recent  wet weather conditions indicate that the potential for problems in soybeans and later planted vegetable crops (lima beans, snap beans, sweet corn, and peppers) is lower than last season. However, we are just starting to see a significant increase in the second CEW flight in some pheromone traps in Maryland and Delaware (e.g. East New Market – 258 per night; East Dover – 110 per night). In addition, we have experienced significant earworm catches in blacklight and pheromone traps in the Milford area and in traps run by a consultant located between the Seaford and Reliance areas. This means that there will be areas with economic levels. Remember that trap catches so far are only an indication of potential problems from local populations. In addition to our resident population, another population of moths generally migrates to the area in early August resulting in the most significant problems in late August through early September. Weather factors and natural enemies also play a key role in regulating populations. In the past, Virginia’s field corn survey has indicated a high potential for problems in soybeans. This survey is used to tell folks to intensify scouting. In the same year, soybean fields are then scouted and no problem occurs. In those years, weather factors, (wet and humid conditions) as well as natural enemies have caused populations to crash and no controls were needed. This points to the need to scout fields starting no later than the second week in August. We are currently seeing moths flying and laying eggs in blooming soybean fields, so these fields should be scouted now. In later planted wheat fields, there is always a potential for defoliation from earworms as well as pod feeding so those fields should be checked as well. The treatment threshold is 3 per 25 sweeps in narrow fields and 5 per 25 sweeps in wide row fields. A pyrethroid or Larvin will provide control.




Fall/Late Summer Forage Seedings - Richard W. Taylor, Extension Agronomist; rtaylor@udel.edu


Now is the time to complete preparations for fall seedings of hay and pasture fields.  If you have not yet taken a soil test sample, do so immediately so you will have ample time to apply and work in lime, phosphorus, potassium, and other needed nutrients before planting.  Planting early can not only help improve yields next year but will allow the crop to become better established before experiencing harsh winter conditions later this year or early next year.  This is especially important for some of the slower establishing species but can be helpful for all forage species.


If legumes will be a part of the seed mixture you’ll be planting, soil pH adjustments before seeding are critical for stand establishment and longevity.  Surface applied lime moves slowly, about 1-inch per year, through the soil so pH adjustments should be made before planting.  Therefore, if your soil test is older than two years, you should go ahead and take another sample especially on hay fields.  For heavily grazed pastures where manure piles are not evenly distributed over the area, a recent soil test of the different areas is critical for proper fertilization.


Fall or late summer seedings are best made as early as possible but when adequate soil moisture is available to support growth.  This year, August seedings are possible.  Weed competition with seedings at this time of year usually is less than that for spring seedings and most of the weeds will be killed at the first killing frost.


If planting for horse pastures, try to choose a mixture that does not include alsike clover since horses feeding on alsike can develop photosensitivity leading to severe sunburn.  Many prepared mixtures do contain this clover so insist that the mixture prepared for you does not contain it.  If you want clover in a mixture, ladino or white clover tolerates continuous grazing well.  Red clover is also a good selection but it performs best under rotational grazing.


Prepare a good, weed-free, fine, firm seedbed for planting.  I prefer to plant using a brillion seeder followed by some method of packing and firming the soil behind the seeder or broadcast the seed and run a cultipacker of some type to press the seed into the soil.  Good soil to seed contact is essential for rapid germination but many forage seeds can easily be planted too deep.  The ideal depth for most seed is 1/8 to ¼ inch deep in moist soil.  If a drill is used to plant the forage seed, running it over the area twice in diagonal directions can be helpful.

Weather Problems For U.S. Soybeans?

That question was being pondered in the commodities market as we entered the first of the week and by mid-week any premium bid into soybeans because of a hotter forecast was being removed. The reason for that is although computer models were forecasting hotter weather in the 6-10 day forecast, it also became apparent that the rains have kept coming.  December corn and November soybean futures prices are expected to remain choppy around their current levels of $1.90 and $4.52 per bushel until USDA's August 11th Crop Production Report is released.


What impact on commodity prices, if any, is the report likely to have?  Commodity traders are already factoring in a very large crop. If the report increases the estimate for crop size we still have some potential for further price declines, to what extent depends upon production forecasts and carryout estimates.

Agronomic and Vegetable Field Tours

Wagons will depart from the area located behind the pesticide storage and handling facility from 8:30 a.m. - noon

The production of squash for freezing is an important enterprise on Delmarva.  Currently, the declining availability of hand harvesting and rising costs of labor threaten the viability of the crop.  Competition from regions with low labor costs, such as Mexico and Central America, also add pressure to the local situation.  Higher plant densities of squash that lend themselves to once-over destructive mechanical harvesting are approaching acceptable yield levels.  Further research on the suitability of the forced balance shaker mechanism for harvest is on-going.  The University of Delaware has conducted field tests to measure the efficiency of different pickle harvesting systems.  In addition, a harvester improvement program is underway to improve the pinch roller harvester system.  Live demonstrations of the squash and pickle harvester will take place as part of the tour.  Ed Kee, Extension Specialist, Vegetable Crops; Tracy Wootten, Extension Associate, Vegetable Crops; Dr. Jim Glancey, Associate Professor, Bioresources Engineering; James Adkins, Extenson Associate, Bioresources Engineering


·         Utilizing Rye Cover Crops for Weed Management

Cover crops use has increased over the past few years due to a number of reasons, primarily nutrient management and erosion control.  Some types of cover crops such as rye have the potential to suppress weed growth.  Studies were undertaken to determine the most efficient way of utilizing rye as a cover crop and obtaining weed control in corn and soybeans.  The purpose of this stop is to share our experiences with rye cover crops for corn and soybean production.  Dr. Mark VanGessel, Extension Specialist, Weed and Crop Management

·         Maximizing the Nutrient Value of Poultry Litter

Poultry litter contains many nutrients (such as nitrogen and phosphorus) that can be used by crops.  Proper management of these nutrients can reduce environmental problems and improve the profitability of crop production.  During this stop we will discuss two ongoing projects related  to the management of nutrients from poultry litter.  The first project is a demonstration of the effect of various rates of litter application, and of starter fertilizer, on corn growth.  The second project is an evaluation of the plant-availability of phosphorus from poultry litter produced using high-available-phosphorus (HAP) corn.  Both of these projects will provide information that can be used to improve the management of nutrients from poultry litter in corn production.  Dr. Greg Binford, Assistant Professor, Soil/Water Quality; Dr. Dave Hansen, Assistant Professor, Soil/Water Quality

Sussex County Safe Kids Day Activities

Located in the tent west of the grove from 8:30 a.m. – 1:00 p.m.


The theme for the 2000 Sussex County Safe Kids Day is “Get into the Game.”  This theme associates with the popularity of sports and the unfortunate escalating number of sports and recreation-related injuries.  While nearly one million children are treated in emergency rooms each year for sport injuries, half of these injuries can be prevented.  To help kids learn to play safe, this year’s Safe Kids Day with support from the National Athletic Trainers’ Association begins a major sports injury prevention initiative.  The objective is to better educate parents and caregivers about keeping their young athletes safe.


The interactive exhibits and demonstrations will make this a safety educational experience that children will not soon forget.  Participants will learn about childhood injury prevention from dynamic speakers, exhibits, puppet shows and costumed characters.  This festival of fun and education will include the following:
