Handy Bt Trait Table: Midwest corn hybrids
This came across my desk the other day, and I hope you find it as useful as I have. The “Handy Bt Trait Table”, by Chris DiFonzo, Michigan State University, and Eileen Cullen, University of Wisconsin, has a great summary table for MidWest hybrids. The table lists the traits currently available (last updated Feb. 2011), insects controlled, and refuge size per trait. The table does not address refuge information for corn planted in cotton designated counties. That information can be obtained by checking with your supplier and/or reviewing the product use guide.

Heavy corn earworm activity in the Northern Neck of Virginia and summary of insecticide work in sweet corn
Based on pheromone moth traps monitored by Rafe Parker from Parker Farms, Oak Grove, Va, corn earworm moth activity has picked up significantly in the Northern Neck Region of Virginia. Counts jumped from less than 10 for past 2 weeks to about 100 moths this week. these moths will be flying to sweet corn, soybeans, cotton, green beans, and tomatoes among other crops. Be on the lookout for the eggs and small larvae of this pest, or begin the preventative spray programs. There are a wide range of effective insecticides for this pest. Sweet corn is probably the most difficult crop to achieve effective control of corn earworm because very few insecticides kill the eggs, eggs develop and hatch quickly in the summer heat, and larvae move down the silks and into ears where they are protected.
