RAYMOND, Miss. -- Mississippi agronomic crop producers now have an important insect control reference guide available on their mobile devices.

“Insect Control Guide for Agronomic Crops,” a publication of the Mississippi State University Extension Service, helps farmers estimate the performance of various insecticides on cotton, soybeans, corn, grain sorghum, small grains, rice and peanuts.

STARKVILLE, Miss. -- Fewer Mississippi producers are looking at grain sorghum as a crop rotation option since an introduced pest became a major problem, a trend Mississippi State University researchers are working to reverse.

The sugarcane aphid is a nonnative pest introduced to the United States in Florida in 1977. By the late 1990s, it had been found in Louisiana. In both states, the pest initially fed on sugarcane. At some point, the aphid began feeding on Johnsongrass, a significant weed found in sugarcane and other crops in the Midsouth.

Mississippi State University annually updates insect management recommendations so the state’s crop producers can rely on good data when making insect control decisions.

STARKVILLE, Miss. -- Knowing when to treat for insect pests in crops is vital to keeping yields high and controlling the costs of agricultural production.

Every year, the Mississippi State University Extension Service updates and publishes its “Insect Control Guide for Agronomic Crops.” The guide includes recommendations for nine crops, including the major row crops, as well as sweet potatoes and pastures.

Angus Catchot, MSU Extension Service entomologist, said all the recommendations in the insect control guide are based on research and tested in the field.

STARKVILLE, Miss. -- Farmers know how to handle ongoing threats posed by insects, diseases, and weeds, but new threats continue to surface that keep them on high alert and change the way they operate.

Mississippi Agricultural and Forestry Experiment Station researchers and MSU Extension Service specialists work to monitor the arrival of new crop threats, determine the best way to address the problem, and pass on those recommendations to producers.

STARKVILLE, Miss. -- Mississippi State University researchers have spent the last few years on the front lines protecting a $33 million dollar crop in Mississippi.

As grain sorghum production grew, producers had to fight off a new pest.
