Insecticides applied to corn during cultivation can provide effective rootworm control.

More and more farmers are using cultivation applications to reduce problems with insecticides applied at planting.  Such problems include decomposition of insecticide before rootworms hatch, especially on early planting.  In addition, thru field scouting, only fields where rootworms develop are treated.

Insecticides applied at cultivation can give some cornborer control in addition to rootworm control.  Drop granular insecticides into whorls of plants where cornborer control is desired.  Granules falling to the ground are then cultivated toward the base of the plant for rootworm control.

For best rootworm control, direct the insecticide to the base of the plant on both sides of the row.  Either liquid or granular formulations work, but the application must be followed immediately with cultivation.

The use of cultivation applications is growing, especially among corn growers who have fields scouted regularly.
