Public Hearing on Proposed New Concentrated Animal Feeding Operations (CAFO) Regulations

Friday, July 16th, 2010

Wednesday, July 21, 2010     7:00 p.m.
Delaware Department of Agriculture
2320 S. Dupont Highway
Dover, DE

The Delaware Department of Agriculture (DDA), the Delaware Nutrient Management Commission (DNMC), and the Delaware Department of Natural Resources and Environmental Control (DNREC) will hold a public hearing on proposed new Concentrated Animal Feeding Operations (CAFO) regulations. Delaware’s current CAFO regulations will expire in the fall of 2010.

The purpose of the hearing is to consider the adoption of proposed new Delaware CAFO regulations that require designated farms and livestock and poultry producers to obtain CAFO National Pollution Discharge Elimination System (NPDES) permits. The proposed new regulations were developed to ensure that CAFOs take appropriate actions to effectively manage manure, litter and wastewater and protect the state’s water quality.

The proposed new regulations were developed by the Delaware Nutrient Management Commission (DNMC), the Delaware Department of Agriculture (DDA), and the Delaware Department of Natural Resources and Environmental Control (DNREC) and are posted on the DDA website, www.dda.delaware.gov. Public workshops were held May 25, 26 and 27 to help farmers and livestock producers understand the CAFO permit process and ask questions.

The public and interested parties are invited to attend the hearing and make comments. Accommodations are available for individuals with disabilities by calling (302) 698-4500 or (800) 282-8685 (Delaware only) for aid or assistance.

Written comments will be accepted from July 1 until 4:30 p.m. July 31, 2010 by: U.S. mail addressed to Mark Davis, Nutrient Management Program Administrator, Delaware Department of Agriculture, 2320 S. Dupont Highway, Dover, DE 19901; by fax addressed to Mark Davis, Nutrient Management Program Administrator, (302) 697-6287; or by email, Mark.Davis@state.de.us.

Delaware NRCS Encourages Producers to Sign Up Early for Three Conservation Programs

Friday, July 16th, 2010

Delaware producers interested in improving natural resources have until October 1 to sign up for three popular conservation programs from the USDA Natural Resources Conservation Service (NRCS). NRCS is offering financial and technical assistance to eligible producers through the voluntary Environmental Quality Incentives Program (EQIP), Agricultural Management Assistance Program (AMA), and Wildlife Habitat Incentive Program (WHIP). After the first batch date of October 1, monthly batch dates will be added as necessary as funding becomes available.

“As more Delaware producers adopt effective conservation practices, we are able to make great progress to improve our water quality, maintain high quality soils, and improve wildlife habitat,” said Russell Morgan, NRCS State Conservationist. Producers are encouraged to apply early to ensure they meet current NRCS eligibility requirements.

Delaware farmers may apply for EQIP to receive financial and technical assistance to plan, design, and install structural conservation practices and to plan and implement management practices on eligible agricultural land. Producers may sign up for available practices including agricultural waste management, nutrient management, irrigation water management, soil erosion control, forest management, poultry house windbreaks, and more.

AMA provides payments to agricultural producers to voluntarily address issues such as water quality, water management, and erosion control by incorporating conservation practices into their farming operations. Some conservation practices eligible for funding include nutrient management, cover crops, high tunnel houses, and conservation cover. Eligible land includes cropland, grassland, pastureland, non-industrial forestland, and other private land that produces crops or livestock.

WHIP offers technical and financial assistance to private landowners to develop, improve, and protect high quality habitat that supports wildlife populations. Land eligible for WHIP includes private agricultural land or non-industrial private forestland. Practices eligible for WHIP funding include filter strips, riparian forest buffers, wetlands restoration (including phragmites spraying), and more. WHIP provides both technical assistance and financial assistance up to 75 percent.

Applications for the above conservation programs are accepted year round. For additional information on EQIP, AMA, or WHIP, visit www.de.nrcs.usda.gov or contact the local USDA Service Center nearest you. In Sussex, call 302-856-3990 ext. 3; in Kent, call 302-741-2600 ext. 3; in New Castle, call 302-832-3100 ext. 3.

Grain Marketing Highlights

Commodities Rally on ‘Game Changer’
The July 9 USDA report was thought by some analysts to be a ‘game changer’. The idea of large stocks of U.S. corn and soybeans growing from previously projected levels for the ‘09/‘10 and ‘10/‘11 marketing years was essentially erased. Instead of building stocks, the U.S. is now looking at a situation where production is just keeping pace with projected demand. In other words, total use is out pacing production for U.S. corn and running very close for U.S. soybeans.

Weekly Crop Conditions were reported to improve slightly for the U.S. corn crop this week while the overall condition of the U.S. soybean crop declined slightly for the fifth straight week. Hot temperatures reported in pockets of the Corn Belt has moved Dec corn futures past resistance at $3.97 ½ overnight. This sets the stage for an extended rally in the near term. Buying interest by both commercial and non-commercial interests suggests that traders might find improving conditions reported this week for U.S. corn to be rather suspect. Hot temperatures are not expected to be widespread, however the new crop stocks-to-use ratio estimated at 10.3 percent for U.S. corn doesn’t leave much room for error, meaning any weather problem perceived or otherwise can lead to extending the rally in the near term for both corn and soybeans. Demand projections for U.S. corn and soybeans could eventually improve in ensuing USDA reports due to dry conditions reported in other corn producing countries e.g., Russia where row crops are under siege of one of their worst droughts reported in 130 years of reporting weather data.

The major question heading into the overnight session was whether the corn, soybean, and wheat markets could continue to rally. All three did, with December corn pushing past resistance while September wheat and August soybeans posted solid gains.

USDA Export Sales Report 07/15
Pre-report estimates for weekly export sales of soybeans (combined old-crop and new-crop) ranged from 27.6 to 36.7 million bushels. The weekly report showed total export sales of 45 million bushels, with old-crop sales of 24.5 million bushels above the 0.9 million bushels needed to stay on pace with USDA’s demand projection of 1.46 billion bushels. Total shipments of 7.6 million bushels were below the 12.1 million bushels needed this week. This report should be viewed as neutral to bullish.

Pre-report estimates had weekly corn export sales at 29.5 to 43.3 million bushels. The weekly report showed total export sales of 39.4 million bushels, with old-crop sales of 26.7 million bushels, well above the 1.6 million bushels needed this week to stay on pace with USDA’s demand projection of 1.95 billion bushels. Total shipments of 41.1 million bushels were below the 50.1 million bushels needed this week. This report should be considered neutral to bullish.

Pre-report estimates for wheat ranged between 12.9 to 16.5 million bushels. The weekly report showed total export sales of 11.4 million bushels, below the 16 million bushels needed this week to reach USDA’s projected 1 billion bushels. Shipments of 13.1 million bushels were below the 19.8 million bushels needed this week. This report should be viewed as bearish.

Market Strategy
July futures contracts are now expired and have moved off the board. New crop Dec ‘10 corn futures are trading at $4.05 per bushel; Nov ‘10 soybean futures at $9.76; with Dec ‘10 SRW wheat futures at $6.12 per bushel in this morning’s trade. The Dow is down 104 points at 10,261. Nearby crude is trading at $77.40 per barrel, up slightly on the day. The dollar index has declined, now trading at 82.56. With commodity markets trending higher, it is important to pay attention to technical indicators for price direction. For example, current technical analysis suggests that we can expect the corn and soybean markets to move higher from current levels. The next level of resistance for new crop corn is at $4.10 to $4.15 per bushel. For soybeans, the next level of resistance is at $9.87 for Nov ‘10 futures. Once those levels are penetrated then there could be some sell off due to the perception of the markets being overbought before resuming upside potential.

Soybean Rust Update – July 16, 2010

Friday, July 16th, 2010

Bob Mulrooney, Extension Plant Pathologist; bobmul@udel.edu

Soybean rust was reported on kudzu in the county of Leon, Florida on July 13, 2010. Soybean rust was reported July 3 in two counties in Alabama and one county in Florida. On June 28, soybean rust was found in one county in Florida. Rust has also been confirmed recently on soybean in the northern portion of the state of Tamaulipas in Mexico. Rust develop has been very slow this season. Conditions are dry in the South and there was not much overwintering on kudzu since the cold winter went so deep into the South.

Agronomic Crop Insects – July 16, 2010

Friday, July 16th, 2010

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

Alfalfa
Continue to scout fields on a weekly basis for leafhoppers. We have also received reports of increased levels of pea aphids and thrips in some alfalfa fields. As a general guideline for pea aphid management, you should consider a treatment in alfalfa less than 10 inches tall if you find 40 aphids per stem. The treatment threshold for alfalfa 10 inches or taller in height is 75-100 per stem. Beneficial insects can help to crash aphid populations; however, as a general rule, you need one beneficial insect per every 50-100 aphids to help crash populations.

In past years, we have seen increases in thrips during hot, dry weather conditions. Hopefully the recent rains will help plants grow ahead of damage. Reports from other areas of the country indicate that thrips feeding on developing leaf tissue can cause the leaves to distort as they emerge. Leaves may also be curled, with a cupped or puckered appearance. Since there are no thresholds for thrips in alfalfa and we have limited experience with this pest in Delaware, the following information from other areas of the country may be helpful when considering the need for thrips management: “ (a) high populations of bean or onion thrips may cause damage, especially in dryland conditions and (b) if a thrips treatment is contemplated, it is best to cut as soon as possible and treat the regrowth if the infestation persists. Thrips are very difficult to control in alfalfa, so excellent coverage is important and two applications may be required for satisfactory results.”

Soybeans
We continue to see a number of defoliators (grasshoppers, blister beetles, Japanese beetles, bean leaf beetles and green cloverworm, etc.) present in full season and double crop beans. As fields enter the bloom to pod fill stages, remember that the threshold drops to 15% defoliation.

We are starting to see an increase in stinkbug populations in full season bean fields so be sure to watch for this insect as the earliest maturing fields begin to set pods. Economic damage is most likely to occur during the pod development and pod fill stages. You will need to sample for both adults and nymphs when making a treatment decision. Available thresholds are based on beans that are in the pod development and fill stages. We are currently following the same guidelines that are being used in Virginia. Thresholds are also based on numbers of large nymphs and adults, as those are the stages most capable of damaging pods. As a general guideline, current thresholds are set at 1 large nymph/adult (either brown or green stink bug) per row foot if using a beat sheet, or, 2.5 per 15 sweeps in narrow-row beans, or 3.5 per 15 sweeps in wide-row beans.

Although we have only seen low levels of soybean aphids populations in a few fields in New Castle County, be sure to watch for this insect in full season beans. This aphid is favored by cooler temperatures so we could see population increases if we start to experience more moderate temperatures. The treatment threshold established in the mid-west is 250 aphids per plant from R1 through R5 stage of growth. The following links from the University of Wisconsin provides good information in sampling, stages of soybean growth and development, thresholds and treatment guidelines http://www.plantpath.wisc.edu/soyhealth/aglycine.htm http://www.plantpath.wisc.edu/soyhealth/pdf/aphid_thresholds.pdf

Potato Disease Advisory #16 – July 15, 2010

7/13–7/14 10 64 7-days 499

I am trying to get back on schedule so here is the latest report only two days additional data but the continued rainfall has increased the favorable environment for late blight, if there are any late blight spores anywhere around the region. There have been no reports of late blight from eastern shore VA, NJ or DE to date.

It is important to keep scouting and maintaining fungicide applications at this time.

Dry to Wet Disorders in Vegetables and Fruits

Friday, July 16th, 2010

Gordon Johnson, Extension Vegetable & Fruit Specialist; gcjohn@udel.edu

Most areas of Delaware received significant rainfall over the last 7 days. For example, Bridgeville had over 3.7 inches of rain, Dover, over 3 inches, Blackbird over 3.3 inches, Laurel 2.2 inches, and Greenwood, 3.2 inches. While this was welcome for soybeans and helped to stop further yield loss in corn, it was a mixed blessing in vegetables. Certainly, crops such as dry land lima beans have benefitted greatly as have non-irrigated corners of pivots (pickles and sweet corn especially). However, heavy rainfall after a long, hot, dry period can lead to certain disorders in other vegetables and fruits. Common problems include:

Fruit Cracking and Splitting
This is most common in ripening tomatoes, peaches, and melons but also can be found in other fruiting crops, especially those that were water stressed prior to the rains.

Edema
Edema is water blistering and is causes when the plant takes up more water than it is transpiring. This is seen as raised bumps on leaves, stems, and sometimes fruits. If water pressure is great enough, these raised bumps will burst leaving small blisters.

Wilting
After heavy rains, in areas of the field that remain waterlogged, plants will wilt once the sun comes out. This is because roots are not functioning properly due to lack of oxygen. Wet conditions can also increase the susceptibility to root, crown, and stem rots due to organisms such as Pythium and Phytophthora, also leading to wilting.

Split Sets
Split sets are common in crops such as snap beans and lima beans where a crop under heat and moisture stress subsequently receives ample rain along with reduced heat. This induces re-flowering and a second pod or fruit set. Split sets complicate harvest timing as well as pest management programs in these crops.

Fruit Quality Reduction
Heavy rainfall along with cloudy weather can cause fruit quality problems in those fruits near ripening. Most common is reduced sugar content.

Basil Downy Mildew Found in NJ

Friday, July 16th, 2010

Bob Mulrooney, Extension Plant Pathologist; bobmul@udel.edu

Basil downy mildew has been confirmed near Vineland, NJ. Basil is at risk. Commercial growers can use ProPhyt or K-Phite — both are phosphorus acid fungicides with the same mode of action. Very few products are labeled currently for this use. Be sure to check fungicide labels for instructions and rates.
