Thrips pressure high but disease pressure low in Southern peanuts

From Southeast Farm Press

Many peanut growers in the Southeast saw early season conditions this year that mirrored those seen in 2013—a cool, wet spring and heavy thrips pressure.

It was reported at this year’s U.S.A. Peanut Congress that while the peanut crop finally got off to a good start in 2014 after early weather delays, thrips pressure was greater than normal and damage was reported in many locations.

Resistant varieties saved Georgia tomatoes from TSWV destruction

From Southeast Farm Press.

Once a major threat to the tomato industry, the thrips-vectored tomato spotted wilt virus (TSWV) has been unable to penetrate the vegetable’s latest line of defense — resistant cultivars.

Scientists from the University of Georgia, University of Florida, Clemson and North Carolina State University have collaborated over the last two decades in an effort to try to alleviate what had become a deadly problem. The results have proven to be beneficial and profitable for tomato growers.

Six Southern scientists receive funding to solve weed, disease problems

Six teams of IPM scientists will use funding from the USDA Southern Regional IPM grant program to explore ways to control weeds and diseases while reducing the use of pesticides. From non-chemical weed control to plant disease management, these teams will explore new tools that farmers can use to battle diseases and weeds, while lowering their use of fungicides and herbicides. This year, USDA has awarded approximately $768,000 to support Southern Regional IPM projects.

Drought creates different insect problems

By Katie Pratt

LEXINGTON, Ky., (July 6, 2012) – Hot, dry weather could have some insects feeding in greater-than-normal numbers on crops like alfalfa, tobacco and some vegetables.

“Alfalfa, with its long tap root, will stay greener and more succulent during a drought than pasture grasses or field crops,” said Lee Townsend, extension entomologist in the University of Kentucky College of Agriculture. “That makes alfalfa attractive to most any insect that can use it, even if the bug normally doesn’t eat alfalfa. Also, irrigated tobacco and vegetables will be very attractive to insects like grasshoppers and stink bugs under these dry conditions.”
