Peaches.
EPA has granted our Section 18 for the use of Provado on stone fruit to control
aphids that vector the Plum Pox Virus. This emergency exemption (Section 18) is
effective from April 1 through Oct 15, 2001. Growers may use a maximum of 4
applications at a rate of 5-6 ounces of product per acre. No more than 24
ounces of product may be applied per acre per year. There is a zero day
pre-harvest interval.
Weed
Control in Greenhouses – Jay Windsor, County Agricultural Agent; windsor@udel.edu
There are no residual
herbicides labeled for greenhouses at the present time. Surflan was labeled,
but is no longer registered for use in enclosed greenhouses. Roundup and or
manual removal prior to setting plants or seed in the greenhouse is
recommended.
The use of weed mats
has proven to be worth the cost of installation and will provide almost total
weed control for many years. The fabric can be used alone or covered with
gravel to provide additional drainage. Remember that transplants will root into
the gravel or even into the weed mats. Providing some sort of benching,
pallets, or framing to allow for air pruning of the roots will help with this
problem.
You have a few choices
of herbicides that can be used in the greenhouse to pick up escapes and spot
spraying even with the crop growing in
the house. Remember that when spraying
any of these herbicides, you should always turn exhaust and horizontal air flow
fans off while spraying. Leave them off for at least a half hour after spraying
to prevent any movement of spray droplets to the crop.
There are three
materials labeled for use in the greenhouse with a crop present;
1)
Reward which is a contact material and may not control perennials effectively
2)
Scythe is another contact herbicide
3)
Finale is a systemic material similar to Roundup that should be more effective
than the contact materials on some harder to control weed species.
Note:
Roundup is not labeled for use in the greenhouse when the crop is present.
Controlling any weed growth around the outside
of the greenhouse is recommended to remove cover for rodents, and host plants
for insects and diseases. You can use residual materials such as Surflan or
Princep in combination with Roundup near the base of the greenhouse. Remember again to turn off the fans if
you have a crop in the house so the spray is not drawn into the greenhouse
through the louvers. Do not use long
residual materials such as Pramitol or volatile herbicides like 2,4-D or Banvel
anywhere near a greenhouse.

Fungicide Update for Vegetables.
The following are some
recently or newly registered fungicides for 2001. Specific use information will
be found in the 2001 Commercial Vegetable
Production Recommendations E.B. 137.
Quadris 2.01F from
Syngenta in addition to tomatoes, potatoes, and cucurbits (cucumbers,
muskmelons, pumpkins & winter squash, summer squash and watermelons) it is
now labeled on spinach to control
white rust and leaf spots, sweet corn
for leaf blights, and carrots for
leaf blights. These changes did not make the new Recs book.
Nova 40WP from Rohm
&Haas is now labeled for rust control in asparagus.
Previcur
(propamocarb HCl) from Aventis has been labeled for late blight control in
white potatoes combined with another protectant such as mancozeb or
chlorothalonil.
Root
Knot Nematodes.
Remember that spring sampling for root knot is
not very predictive (not very accurate) of what the overwintering population
might be. Population levels tend to be lower and thus more easily missed when
random samples are taken. In winter, a higher proportion of the population is
in the egg form which may not show up in the lab technique that is used to
extract the nemtodes from the soil. Zero counts and low counts are hard to
interpret at this time of the year. High counts at this time of year indicate
high levels in the field and are reliably used for decision making. Fall
sampling is best for root knot.
Winter Temperature Index for Predicting
Stewart’s Wilt in Sweet Corn 1994-2001.
Corn flea beetles are the overwintering host and
vector of Erwinia stewartii, the
bacterium that causes Stewart’s wilt.
Winter survival of the flea beetles can be predicted using a winter
temperature index which is calculated by adding the average temperature for
Dec., Jan., and Feb. Flea beetles do not survive well when the average
temperature is below 27oF for any month. If the temperature is above
33oF, flea beetles may be present in early plantings of sweet corn.
The occurrence of Stewart’s wilt on early-planted sweet corn usually
corresponds with the ability of flea beetles to overwinter. The following table
shows that overwintering is very likely again in Delaware and the prediction
would be for a severe Stewart’s wilt season.
Fortunately for Delaware growers, resistant varieties of sweet corn have been available for most processing sweet corn. A dependable level of resistance in fresh market sweet corn has been more elusive. Despite years of favorable flea beetle overwintering, we continue to have few losses from Stewart’s wilt. Why? Growers have planted resistant varieties and have effectively used the insecticides that have been available. Growers need to continue to plant the most resistant varieties available and scout sweet corn for flea beetles and treating with insecticides when thresholds are exceeded. The use of seed treatments to control flea beetles is another avenue that is being carefully examined and research is currently underway to see if it will be of value to Delaware growers.

Field Crops
Field Crop Insects - Joanne Whalen, Extension IPM Specialist ; jwhalen@udel.edu
Field
Corn
Seed
Corn Maggot.
Although winter temperatures have been colder or
at least more normal compared to the last few seasons, we are starting to find
seed corn maggot flies laying eggs. Cool, wet conditions at planting, the use
of manure or plowing under of green cover crops close to planting all favor
maggot problems. Depending on spring weather conditions, most early planted
conventional corn and all no-till plantings will be susceptible to seed corn
maggot attack. If treatments are applied properly, seed treatments have
provided effective control. This season, in addition to diazinon and permethrin
based seed treatments, will now have the option of
using Gaucho or Prescribe treated corn. Our
research results from last season indicate that these products, both containing
imidacloprid, will provide effective seed corn maggot control.
White
Grubs.
Although we feel that agronomic and weather factors played the primary role in predisposing corn to lodging last season, grub damage was also a consideration in numerous fields. The primary soil insect pest found in the root zone of lodged corn plants was the true (multi-year) white grub. However, we also found annual species present under corn roots. If grubs were found in fields last fall, understanding the biology and life history of the two main types of grubs is important when developing a management strategy.
Annual White Grub
– Japanese Beetle, False Japanese Beetle and Asiatic Garden Beetle: In
general, these are the most common types of grub encountered in corn fields at
planting time. Larvae are sensitive to soil moisture and texture so we often
find the highest populations on sandy knolls.
Since adult beetles are attracted to flowering grasses, we can also see
grubs in low areas where weeds were present the previous season. Soil moisture
and texture are generally not uniform throughout any given field; therefore,
white grub infestations are not uniform.
Within the same field, some areas may be completely destroyed while
others are undamaged. Larvae generally pupate in late-May to early-June. Therefore, late-planted corn often escapes
annual grub damage.
True White Grubs
- May and June Beetles: In comparison, true (“multi-year”) white grubs
complete a single generation in three years. Larvae are also sensitive to soil
moisture and texture so infestations appear in spots in fields. Eggs are laid
by the May or June beetle adult in July.
The eggs are laid one or more inches below the soil surface, usually in
sod or patches of grassy weeds in cropland areas. First instar larvae emerge 2-3 weeks after egg deposition. These young grubs feed on organic matter,
roots, and other underground parts of the plant throughout the growing
season. During the first year, the
damage to infested crops is usually minimal.
However, if populations are heavy (> 5 per plant), you may see root
damage and eventual plant lodging. This
type of feeding may also make plants more susceptible to stalk rot and root
rotting organisms. Larvae molt once during their first summer. Grubs then move to a depth below the soil
frost line. Second instar larvae
migrate upward and begin feeding on plant roots in the spring of the second
year. Larvae feed heavily on roots the
entire second summer; thus, damage is usually greatest in the second year of
the life cycle. They become nearly full-grown
during this summer.
Sampling
and Decision Making for Grubs.
At planting, soil sampling can be used to
determine the density of both types of grubs as well as which species is
present. If populations are above 0.5 – one grub per square foot in sandy soils
or 1-2 per square foot on heavier soils, the use of in-furrow applications of
soil insecticides provides the best control of either type of grub. In our
area, Counter and Force have provided the most consistent control of grubs.
However, in-furrow applications of Fortress and Regent as well as
Prescribe-treated corn seed are also labeled for grub control. Remember, at
planting insecticides are only designed to provide control of grubs present at
planting time. You should not expect control of larvae present in August and
September that resulted from eggs laid in early July.
Because of the differences in the life cycles
and damage potentials, it is important to know which species is present. The pattern of hairs or spines on the
underside of the last abdominal segments is the best way to distinguish between
true/multi-year species and annual species grubs.

Aphids – Although we still find a spotty distribution of Barley Yellow Dwarf Virus (BYDV) in the state, aphid management can play a part in reducing losses from BYDV. Weather conditions were mild in October and early November, but temperatures were colder in late November and December compared to recent years. Counts in our aphid management studies were high in October, but went to almost zero through the winter months. Evaluations in early March showed no aphid activity. It still appears that the two most important times to control aphids to help reduce problems from BYDV are the first 30 and 60 days after plant emergence. The cold winter weather has reduced winter aphid movement, reproduction, and spread. Additionally, it appears that a large proportion of the aphid population was killed. As a rule of thumb, temperatures below 30 degrees F result in significant aphid mortality. As weather warms up again, fields should be scouted for aphids and beneficial insect activity. In late winter to early spring, the treatment threshold of 150 – 200 aphids per foot of row should be used. However, if you have a history of BYDV in your area and localized populations are causing stand reductions, treatment may be needed at 10-15 aphids per foot of row. Information from Kentucky indicates that there is generally no yield impact after Feeke’s growth stage 4 (stem elongation). Whether you decide to spray or not, remember the BYDV you see this spring is generally a result of what happened in the fall. Warrior, dimethoate, Lannate and Penncap will provide aphid control. Dimethoate will provide poor control if temperatures are below 60 degrees F.
Small Grain Weed Control -Mark VanGessel, Extension Weed Specialist ; mjv@udel.edu
It is time to consider your weed control for the
small grain crop. Fields that were
no-tilled or chickweed emerged shortly after planting in the fall are fields to
check first for spring treatment. If
you have wild garlic or Canada thistle, the time of application should be
delayed since you need to spray these weeds when they have fully emerged. Coverage is important for these
species. If weed pressure from winter
annuals is great, it may not be possible to get control of the winter annuals
and perennial with one application. In
that case, two applications maybe required.
You can mix your Harmony Extra with nitrogen. If spraying Harmony Extra with nitrogen be sure to pre-mix it in
water first. If using nitrogen as your
carrier, no need for a surfactant unless wild garlic is over 8 inches
tall. Applying Harmony Extra in
nitrogen diluted with water, use a non-ionic surfactant at ½ to 1 pint/100
gallons of solution. If applying it in
water, use non-ionic surfactant at 1 qt/100 gallons.
Have you considered resistance management with
your small grains? Most of the small
grains get treated only with Harmony Extra, which contains two ALS-inhibiting
herbicides (some type of herbicides as Pursuit, Accent, Classic etc). And many weeds have developed resistance to
herbicides that have this mode of action.
Consider how often a field is planted to small grains and how often it
gets treated with Harmony Extra. If this
rotation is short, 3 years or less, consider tankmixing another herbicide with
Harmony Extra to minimize the risk of developing herbicide resistant weeds.
Finally, the following are the timing
limitations for small grain herbicides.
The timing restrictions are based on crop safety.

Soybean Cyst Nematodes.
It
is not too late to soil test for the soybean cyst nematode (SCN). If soybean stubble
is present, sample with a soil probe 6-8 inches deep between the plants in the
row. Sample size should be 20-25 cores
taken in a zig-zag pattern across the field. Ideally samples should represent
no more than 10-20 acres. Sample bags and information sheets are available from
the county extension offices. The cost is $10 per sample. New fields and those
to be planted with susceptible varieties are the most critical to sample at
this time. Remember that last seasons good growing conditions also favored SCN
reproduction as well, and SCN population levels will be high where susceptible
or moderately susceptible varieties were grown.
Keep
in mind, that Roundup Ready varieties do not have specific resistance to race 1
of the soybean cyst nematode (SCN) but carry some resistance. This makes monitoring SCN populations more
important if you are growing continuous soybeans and using Roundup Ready
varieties, especially after last year.
Periodic sampling can indicate if SCN populations are increasing.
Variety trial results are available from the county Extension offices and the
following website http://ag.udel.edu/extension/variety%20trials/index.html
Choose
the best variety for your situation. Without aggressive management such as
planting SCN-resistant varieties and rotating with non-host crops, such as
corn, sorghum, vegetables (except snapbeans) yields can be reduced by 33%, or
more when pre-plant cyst numbers are high and the weather is hot and dry.
Spring Small Grain Fertilization - Richard W. Taylor, Extension Agronomist ; rtaylor@udel.edu
Some small grain fields have already been fertilized,
but a number of fields have yet to receive their first spring nitrogen (N)
application. Frequent rain events last
summer not only meant excellent yields in most cases (this removed large
quantities of N), but also removed by leaching or denitrification most residual
soil N. In addition, a dry and cold
fall, resulted in poor growth and development of many small grain fields. Other than fertilizer applied at or shortly
after planting, little N is available to the small grain crop this spring since
the prolonged cold weather has meant that soil temperatures are still too low
to allow adequate N mineralization from the organic matter reserves.
There are other concerns about
fertilizing small grains this season.
Nitrogen prices are much higher than last year. The weather conditions have resulted in
small, poorly tillered plants with smaller than normal root systems. In research on wheat fertilization in the
past, we have found that yields increase only marginally after about 60 to 80
lbs N/A and that split applications can increase yields enough to justify the
expense of multiple applications. With
the high price of N and low wheat price, I would suggest limiting your N rate
to no more than 80 lb N/A and applying it in a split application with about 60
percent as soon as you can get over the field and the remainder at Feeke’s
growth stage 5 (leaf sheaths erect, fully tillered, and the first node just
visible above the soil surface).
A second option to determining N rate at this
stage is to use the data from Virginia Tech that relates N rate to tiller
density. At tiller densities of about
60 tillers (a tiller is counted if it has 3 leaves visible) per square foot or
less, their research suggests applying 60 lb N/A. At about 75 tillers per square foot, the suggested rate is 40 lb
N/A. At 90 tillers per square foot,
apply 20 lb N/A and there are 100 per square foot or more do not apply any N at
‘green-up’. A second application is
applied at Feeke’s 5 or Zadok’s 30 and is based on tissue N content at that
time.
Fertilizing Pasture and Hay Fields for Spring Production -
Richard W. Taylor, Extension Agronomist ; rtaylor@udel.edu
When you think of fertilizing pastures and hay
fields, you’re most likely thinking of nitrogen (N) based fertilizer. For pastures and hay fields that are
predominately grass (less than 25 percent legume), N recommendations call for
multiple split applications of about 50 lb N/A now and additional applications
after each grazing cycle or hay cutting.
For hay fields, you should temper early spring application based on how
successful hay drying/making has been in the past on each field. If the field often produces too much grass
to properly dry and bale it, cut back on the amount of N fertilizer early to
reduce the size of the first harvest.
Plan on more later to boost second cut yields when the chance of good
hay-making weather is improved.
For pastures and hay fields with more than 25
percent legume, cut your N fertilization rate unless you are trying to reduce
the legume component. You can do this
by adding extra N to increase the competitiveness of the grass against the
legume. Grasses are far more efficient
at using fertilizer N than are legumes.
For alfalfa fields, research at Delaware State
University by Dr. Ed Jones and Harris Swain indicates that we should change the
ratio of potash (K) to phosphorus (P) from 4 to 1 to a value closer to 3 to
1. Actual P and K fertilizer rates for alfalfa
are under review based on the data from Delaware State University. I will keep you informed of any changes
approved by the review committee.
Finally, review soil test data to determine the
potential need for lime, P, K on pastures and hay fields. If lime is needed, it can be applied now or
immediately following removal of a hay crop or at the end of a grazing
cycle. Split apply P and K needs with
about one-half of the total required after the first harvest and the second
half in late summer to prepare the forage crop for winter dormancy. Boron should be applied with P and K on all
forage fields containing 25 percent or more legume.

Marketing Highlights - Carl German, Extension Crops Marketing Specialist ; clgerman@udel.edu
March Crop Report Highlights
USDA decreased the carryover estimates for the
2000/01 marketing year for U.S. soybeans and wheat. The reduction reflected a
15 million bushel decrease for the soybean carryover (now placed at 330 million
bushels) and only a 5 million bushel decrease for wheat (currently projected at
834 million bushels).
The carryout estimate for U.S. corn was
increased by a whopping 50 million bushels, and is now placed at 1.941 billion
bushels. The supply and demand balance sheet for U.S. corn has simply gotten
worse since the fall. First, the 2000 crop production estimate turned out to be
larger than originally projected and USDA's outlook projections for corn
exports have not held up. Grain analysts are now realizing that it isn't likely
the U.S. will meet the initial export projects for corn in the current
marketing year. This is likely to spell trouble for U.S. corn prices in the
event a 'weather' market does not materialize.
Brazilian
and Argentine Soybean Production Reported at Highest Level in History
Although beginning to sound like a broken
record, this statement which was true in February was also found to be true in
the March report, with one exception being the projected size of the Argentine
crop. While the Brazilian production estimate remained the same as the February
reported number of 35.5 million metric tons, the Argentine estimate was
increased another 1 million metric tons and is now projected at 25 million
metric tons.
Setting
Realistic Pricing Objectives for 2001 Corn, Soybeans, and Wheat
Realistic pricing objectives for corn, soybeans,
and wheat are given as follows: $2.50 Dec corn, $5.00 Nov beans, and $3.00 July
wheat. These pricing levels are presented as good places to either forward
price and/or to take price protection. Currently, none of these price
objectives can be met. Therefore, we are in a holding pattern concerning new
crop sales.
Grain
Marketing Summary
Delaware loan rates remain unchanged at $2.10
per bushel for corn, $5.36 for soybeans, and $2.67 for wheat. Price moves on
the CBT to the price objectives given above should be used to get to the 50%
sold level for intended dry land corn, and wheat production. In the likely
event that soybean prices do not rise above the loan rate, it may become
necessary to take risk protection at the $5.00 level, without making any cash
sale. Do not make and forward cash sales for corn, soybeans, and/or wheat sales
for 2001 below the loan rate.
