Pest Alert: Thrips in AL Cotton

May 31, 2019

With persistent dry weather in the forecast for the near future and a reduction in wild plant hosts, thrips are making their way in especially large numbers to cotton plants in AL. Pest Patrol entomologist Dr. Ron Smith provides management recommendation in his latest update, and reports that late-planted cotton may need more than 1 foliar application this year.

Thrips are tiny insects that range in color from yellow to black. They feed on cotton leaf tissue, leaving silvery outlines on veins and, in worst cases, causing leaves to die. Cotton plants are most vulnerable to thrips in the first or second leaf stage. When scouting, growers should shake plants over a piece of white paper to catch and spot the darker bugs.

Infestations of thrips can be reduced with management options, treated seed and insecticide. Rain can also reduce thrips pressure.

CentricĀ® foliar insecticide will supply cotton growers with proven insect protection. Providing fast-acting, long-lasting control of yield-robbing pests, Centric aids in the production of a profitable cotton crop. This insecticide option delivers consistent control, targeting insects in both Bt and conventional cotton.
