Chronic wasting disease (CWD) was not found in samples taken from hunter-killed deer during the state's 2010 hunting season, according to Dr. Walt Cottrell, Pennsylvania Game Commission wildlife veterinarian. "We are pleased to report that Pennsylvania continues to have no confirmed or suspected cases of CWD in wild deer or elk," Cottrell said. "By conducting these tests from a random sample of hunter-killed deer and on all hunter-killed elk, we continue our efforts to find the disease in wild deer and elk in the state."
Sandea (halsulfuron-methyl, Gowan) has been approved for use on blueberries in Pennsylvania. Sandea has both preemergent and postemergent activity on certain weeds that can become problematic in blueberry plantings. Labeled rates are really low (1/2 to 1 oz/acre), so make sure that your application rate is correct. Be sure to follow precautions and directions on the label, and avoid contact with any green tissue.

If not taking into account the volume of rainfall we are receiving during this early part of the season, the degree-day (DD) comparison between this season and previous years suggests that DD accumulation (base 43) since January 01 is similar to DD accumulations observed during the last few years, with the exception of last season, when at this time we were already at petal fall stage on apples. Monitoring of insect pests in pheromone traps also suggests a relatively “normal” year for the development of insects.
Penn State Extension's On-Farm Research Program and Crop Management Team collected cover crop biomass samples from the statewide network of demonstration sites in November 2010. Results of the biomass sampling are now available by individual site and pooled across sites and cover crop mixtures. Forage quality samples were collected at the Lebanon, Montgomery, and Dauphin County sites for the annual ryegrass + crimson clover, oats + cereal rye, and cereal rye + tillage radish mixtures.

Beyond the new pesticides mentioned in a recent article for berry crops (Portal on low-growing berries, Altacor and Danitol on caneberries), here are a few more additions:
Okay, so you’re thinking about raising livestock for direct-to-consumer sales. You’ve figured out what kind of livestock you want to raise, what kind of infrastructure you will need, soil tested your pastures, the works. One question remains; how much should you charge your customers?
Rye cover crops are one of the fastest growing cover crops in the spring. To ensure high quality ryelage harvest, producers must have harvest equipment ready to go. Quality of ryelage rapidly decreases with maturity and one day in harvest delay can make the difference between high quality and average to poor quality forage. If producers rely on custom harvesters, these individuals need to be contacted now to plan approximate harvest schedules.
With tight economic conditions there has been increased interest in using legume cover crops to supply N to corn. While this has not been the subject of a large amount of research, a recent summary of the available research has shown that red clover established in wheat or oats and then left to grow as a cover crop until the next season can contribute between 45 and 155 lb N/A to the next corn crop.
Laboratory bioassays were conducted this winter at the Penn State Fruit Research and Extension Center to assess the toxicity of various insecticides against adults of brown marmorated stink bug (BMSB). The results provided valuable information relative to insect management during the upcoming growing season. The biology and behavior of brown marmorated stink bug (BMSB, aka Asian stink bug) present many challenges. BMSB has a plethora of available host plants and has the ability for unrestricted movement. Insect biology and monitoring issues are undefined and there is no biological control. Each instar (except eggs) can cause damage, and initial injury on fruit is inconspicuous. Alternate management options to be investigated during the growing season include border applications, treatment of surrounding vegetation, and trap crop plantings. Research on spatial and temporal distribution will also be conducted.
This past Saturday, nearly 5 inches of rain fell around the Gettysburg area in a short period of time. One grower contacted me and was wondering about recently applied herbicides and the potential for washing the herbicide too deep. I thought this would be a good time to review some of our residual herbicides and the mobility or potential to be rendered ineffective due to rains. The table at the end of this article lists the common tree fruit residual herbicides and the tendency of them to leach or move across the soil. Leaching is the physical process of movement of herbicides in soil water flow and is influenced by several factors, including solubility and soil adsorption. The amount of movement is influenced by the amount of herbicide in the soil, soil texture, and the extent of water movement. The amount of herbicide in the soil solution is a function of the solubility of the herbicide and strength of soil binding (adsorption). Soil adsorption is a measure of the affinity of an herbicide to soil organic matter. Herbicides that are low in solubility and have a high affinity to soil particles will be less likely to leach. Since organic matter is the most influential soil factor governing adsorption, the Koc (ml/g) of a herbicide is a very useful measure of its tendency to move with water in soil. Herbicides that are soluble with low soil adsorption are prone to leaching, including diuron, napropamide, and norflurazon. Herbicides that are low in solubility and not prone to leaching, include, trifluralin, and pendimethalin.
