Pumpkin Harvest – Ed Kee, Extension Vegetable Crops Specialist; email@example.com
The Pumpkin Production Guide points out that to ensure high-quality pumpkins, it begins with maintaining healthy vines. This has been a challenge this year, but there are productive pumpkins fields ready for harvest. Pumpkins will reach full size about 20 days after fruit set, begin to show color at 30 days, and should be fully colored 45 days after fruit set. Maintaining healthy vines through disease control programs is the first step to also having good, solid stems (or handles) at harvest. Stem hardening peaks 20-35 days after fruit set and doesn’t change significantly beyond 35 days from fruit set. If a stem is shriveled after harvest, it is an indication of plant stress of some sort, either disease, plant nutrient deficiency, or too little vegetative growth to support the fruit load.
When harvesting, only harvest mature, sound, disease-free fruit. Handle carefully. Picking them by the stem maybe a good way of “grading out” the fruit, but ideally the pumpkins should be harvested by picking them up from the bottom.
The best long-term storage temperature for pumpkins is between 50 and 60 degrees. However, healthy, disease-free pumpkins that are exposed to daily fluctuating temperatures between 35 and 70 degrees will store quite well. This is often the scenario for most growers and marketers. If temperatures go over 80, the respiration rate increases and weight loss occurs. Pumpkins should be dry when stored, whether in a shed, market, or on a wagon.
Vegetable Crop Insects -
Continue to sample fields for diamondback (DBM) and cabbage looper (CL) larvae. We can also find fall armyworm and beet armyworms feeding on plants. A treatment should be considered if you find 5% of the plants infested and before larvae move into the hearts of the plants. If DBM and CL are both present, Avaunt , a Bt, Proclaim or Spintor will provide control. If cabbage looper is the predominant species, a pyrethroid, Intrepid, or Confirm will also provide control.
Lima beans will continue to be extremely attractive to corn earworm moths. Since moth catches are generally high in black light and pheromone traps, you may need to spray the latest planted fields at least 2 times for earworms. A treatment will be needed if you find one corn earworm larvae per 6 ft of row. Capture, Lannate, Mustang or Warrior will provide earworm control. The higher labeled rates will be needed if population levels are high and worms are large at the time of treatment.
Be sure to maintain a 5-7 day spray schedule for corn borer, corn earworm, beet armyworm and fall armyworm control. Be sure to watch carefully for corn borers and beet armyworm since we are seeing an increase in egg laying activity from both insects. In addition, small beet armyworms can be found feeding on the leaves.
At this time, all fresh market and processing snap beans will need to be sprayed for corn borer and corn earworm control from the bud stage through harvest. On processing beans, Orthene should be applied at the bud and pin stages for corn borer control. However, since Orthene provides poor corn earworm control, a pyrethroid plus Orthene should be used at the pin spray to achieve corn borer and corn earworm control. Remember, Orthene has a 14 day pre-harvest interval. After the pin spray, be sure to check local trap catches to determine the spray interval for your area. You can check our website for the most recent trap catches and information on how to use this information to make a treatment decision in processing snap beans.
The first webworms and beet armyworms can be found in recently emerged plants. Controls should be applied when worms are small and before they have moved deep into the hearts of the plants. Also, remember that both insects can produce webbing on the plants. Since beet armyworms are more difficult to control, chemical selection is important. Confirm, Intrepid or Spintor will be needed for beet armyworm control. If webworms are the predominant species, permethrin, Confirm (8 oz/acre), or Intrepid (8-10 oz) should be used. Generally, at least 2 applications are needed to achieve control of webworms and beet armyworm.
All fresh market, silking sweet corn should be sprayed on a 2-3 day schedule.
Field Crop Insects -
We have had our first report of economic levels of soybean aphids in double crop soybeans in Kent County. We have also received reports of economic levels of soybeans aphids in double crop fields in
Corn earworm levels remain low throughout the region. We can still find a few larvae but numbers are well below threshold. The latest planted fields with blossoms and open canopies will be attractive to egg laying moths. In addition, we are still catching high numbers of corn earworm moths in black light and pheromone traps. So, if you have not scouted your fields be sure to look at them during the next week to 10 day period since there are always hot spots of activity that can take us by surprise. A treatment should be considered if you find 3 corn earworms per 25 sweeps in narrow fields and 5 per 25 sweeps in wide row fields ( 20-inches or greater).

Late Maturing Crops Driving Commodity Bidding
Time is running out for late maturing corn and soybean crops in the Northern tier of the U.S. Corn Belt. The August crop production report slated
The weekly export report totals were slightly better than the top end of trade guesses for wheat at 20.5 million bushels. Corn totals (combined old and new crop) were at 23 million bushels, well within the expected range. Weaker-than-expected soybean totals at 7.1 million bushels may be somewhat offset by strong new crop meal and oil sales.
Corn crop weekly condition ratings have deteriorated in nearly every state since August 1. This has traders taking note and exiting short positions, at least until more is known. Dec '04 corn futures have rallied significantly over the past two weeks and are now trading at $2.43 per bushel, about 16 cents better than the August low. Even though crop ratings have declined it is important to note that the overall rating in the excellent/good category is well above last year and online for a very large to record crop.
If early frost does not occur, and we see normal frost dates, the soybean market is likely to undergo a correction back below $6.00. The primary risk at this juncture is simply that Mother Nature could turn a cold shoulder on the Northern tier of the U.S. Corn Belt and take some of the crop size away. Note: forecasts for a hard frost coming early are still rather 'iffy'. Nevertheless, the market may well hold onto some frost premium going into the holiday weekend. November futures have bounced back over 50 cents this week and are now near $1.00 per bushel above the August low.
Harvest of spring wheat continues to be plagued by wet weather in the Northern Plains and the Canadian Prairie. Freeze and sprout damage has already occurred to some extent, with more frost forecast for
We all hear much talk about 'turning points' in the news concerning most any topic e.g., turning point in the war, turning point in the election, turning point in the trial, etc. To some degree, weather developments over the next seven to ten days will serve as a turning point in determining the price level that farmers will have to contend with at harvest. An early frost would result in price rewards from current levels for '04 corn and soybeans that remain unpriced and are sold at harvest. An early frost would also give farmers a chance to look ahead to next year's pricing decisions and consider locking in a profitable price on a percentage of '05 intended production for corn, soybeans, and wheat ($2.63; $6.13; and $3.46, respectively). However, if the threat of an early frost comes out of the picture then pricing opportunities and pricing decisions are likely to change considerably, along with desirable harvest time pricing opportunities.

Broiler Risk Management Workshops
Maryland Cooperative Extension, Maryland Department of Agriculture,
The DELMARVA broiler industry had
a real scare last winter with the AI outbreak. Fortunately, the damage was
limited as the outbreak was controlled. Growers have a lot of questions about
how this outbreak was managed. More information on these actions are crucial so
growers are better prepared if another outbreak of AI or other contagious
diseases occur. A main topic in this workshop is how this crisis was managed.
Dr. Edwin Odor of the
Another major topic is the possibility of insurance for broiler
production. Dr. Barry Barnett, a crop insurance expert from the
Other speakers will discuss broiler bio-security scores, preventing electrical outages, use of computers, calculating profitability, and managing debt, which concern other major risks faced by broiler producers.
The workshops are targeted to poultry growers. Individuals involved in businesses serving farmers, and state and local governments would also find this workshop helpful. The public are also welcome.
Because of USDA support, the workshops have no registration fee. Lunch is also provided. Registration is required to provide head counts for lunch and handouts.
