A series of three control experiments was conducted to evaluate the effectiveness of various insecticides for the control of insects injurious to birdsfoot trefoil, Lotus corniculatus. L., grown for hay and seed.

Of the materials tested for eontrol of the lepidopterous leafroller, S paraganothis xanthuides Walker, parathion at 0.5 lb. per ll1'rewas found to be highly effective and the most economical to use.

The application of lindane at 0.25 lb. per acre for the control of the meadow spittlebug, Philaentts leucophthalrnus (L.), re- suIted in significant increases in yields of forage and seed. Thiodan®(6,7,R,9,10,lO-hexachloro-1,5,5a,6,9,9a-hexahydro-6,90 methllno-2,4,3-benzodioxathiepin-3-oxide) applied at the rate of 1.0 lb. per a1're as a pre-bloom treatment also gave significant increases in yields of forage and seed. Parathion and aldrin applied at 1.0 lb. per acre as a pre-bloom treatment both gave significant increases in the number of legumes produced.
