STONEVILLE, Miss. (WJTV) – Tucker Miller has a list of row crop producers who depend on him to manage insects in their fields, and every year brings a different pest challenge that threatens crop profitability.

Miller, an independent crop consultant with Miller Entomological Service Inc. in Drew, Mississippi, said there is always uncertainty in insect matters.

“We try to be on top of the situation by scouting and looking for the insects that usually appear at certain times of the crop growth stage,” Miller said.

“We work closely with the Extension Service because they have test plots across the state and on a lot of my clients’ farms,” he said. “They use these plots to develop thresholds for insect control and to test the effectiveness of different chemicals labeled for insect control.”

For insect control, the Mississippi State University Extension Service offers the “Insect Control Guide,” available in printed form and online. This document includes a wealth of information on different pests, chemical control and when to trigger a pest treatment. The research-backed data is a primary tool for Mississippi farmers navigating their way to a successful harvest.

Insect control got a lot harder in 2021 when farm chemical costs increased almost fourfold by the end of the year.

Higher than usual input costs can compress profit margins. At MSU’s Row Crop Short Course held in December, specialists updated participants on the insect scene from 2021 and advised on decision-making criteria for 2022.

Scouting and monitoring pest populations are always the first steps in insect control. After the insects are identified and their populations confirmed, producers then must assess their crop’s tolerance level and injury, which is often dependent on the crop’s maturity status.

MSU agricultural economists gather information on all the crop input costs and then compile that with possible market prices for the crop. Entomologists used this data along with other information to establish economic thresholds for the different row crops, a reference to the level of pest infestation at which management action is financially justified.

Each insecticide application decision should be weighted by a variety of factors such as crop value, effectiveness of the treatment available and management cost.
