High numbers of thrips continue to be reported on cotton, and this may be a record book year for thrips across the Belt. The bad news is that these high numbers can further delay a relatively late crop. Seed treatments are not bullet proof to high migration of adults and poor growing conditions. The good news is Continue reading
I previously posted a blog article about utilizing pheromone moth traps for monitoring populations of southwestern corn borer, SWCB (http://www.utcrops.com/news/2011/03/southwestern-corn-borer-moth-traps/). There is a link within this article on how to interpret and make decisions based on the numbers of moths being caught. If you look at moth trap counts
DuPont has received a label for Prevathon which includes uses in cotton, pasture grasses, and field, pop and seed corn. The active ingredient (rynaxypyr or chlorantraniliprole) is the same as in another DuPont product called Coragen. However, Prevathon is the product that will be marketed in field crops.

COTTON: A number of private consultants have already commented on high thrips pressure this year, some as high as 6-12 thrips on cotyledon and one leaf plants. This high pressure is a common theme across much of the Belt this year. Repeating from last week …. the risk of thrips causing yield loss increases as the time between planting and cotton reaching the second or third true leaf stage increases. Keep track of the days elapsed between emergence and seeing the first true leaf. Consider applying insecticide Continue reading
The annual UT Cotton Scout School will be held Friday, May 27th. The school will be held in Jackson at the West Tennessee Research and Education Center. Registration will start at 8:00 AM, and the program will begin at 8:30 AM. A box lunch will be provided, and those interested can attend a “go to the field” session after lunch. Registration is FREE and pre-registration is NOT required. Topics covered will include cotton growth and development, identification of pests, beneficial insects and weeds (including those resistant to glyphosate). Live and preserved specimens will be available for viewing.
Most our cotton is just coming up and we are thinking more about planting than thrips management. However, the cool conditions that have slowed emergence means that seedling will be exposed to thrips for a relatively long time. Continue reading
There have been a few reports of armyworms clipping heads in wheat. This behavior is not always predictable and can occur even when infestation are not that impressive. The typical recommendation to treat when Continue reading
