Ileptachlor-Low-Cost Control In the spring, warm enough weather to Btart alfalfa growing will also bring out over-wintered adult w;vils. Unless these adults afe Mind they will begin to lay eggs. Thus it is much easier to kill the relatively few adults in early spring than to try to control the tremendous tremend-ous numher of larvae which can Jiatch out later in the season to damage alfalfa. Why Early-Season Control? Karly season control is important tor another reason besides the fact that it is easier to control a few .adult females than countless larvae .later on. When heptachlor is applied in the early spring, bees which are necessary for pollination of alfalfa jjrown for seed, and parasitic wasps which are an important factor in natural control of alfalfa weevils, are not active . . . and therefore are not endangered by the insecticide. Use Standard Equipment tleptachlor can be applied with standard spraying or dusting equipment, equip-ment, either ground or air. Apply during warm weather when alfalfa plants are about H to 2 inches tall, and when adult weevils are most active.
