Texas producers delaying wheat planting due to grasshoppers

High Plains wheat producers who are normally ready to put seed in the ground might want to hold off this year, according to Texas A&M AgriLife Extension Service specialists in Amarillo.

With the extremely heavy pressure from grasshoppers, as well as other insects and diseases due to the wet year, waiting until the growing plants or  “green bridge,” is broken is advisable, said Dr. Jourdan Bell, AgriLife Extension agronomist, and Dr. Ed Bynum, AgriLife Extension entomologist.

“While we know wheat producers generally begin to plant in September, it really would be best if they could wait until mid-October to avoid grasshoppers and other issues,” Bell said. “The risk will be losing some of the grazing in the fall, but wheat that is planted earlier is more susceptible to insects and pathogens.” Continue reading

Texas A&M has online insect identification resources

Texas A&M AgriLife has several online insect identification resources for your use.

For aphids, http://aphid.aphidnet.org/, can be used to identify the 66 most polyphagous and cosmopolitan aphid species in the world.

For grasshoppers, http://itp.lucidcentral.org/id/grasshopper/adult/Media/frmsetRLGH.htm is a great tool to help identify species.

Dr. Salvadore Vitanza reports http://idtools.org/ is a wonderful resource with a wealth of information, fact sheets, photographs, and Lucent technology identification keys. He reports that these tools make identification quick and easy and was especially impressed by the “Find Best” magic wand icon.

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.”
