The alfalfa weevil destroys a great deal of alfalfa in northern Utah and southern Idaho. It also inhabit southwestern Wyoming and is spreading slowly to new territory in all directions. I may in time infest most of the United States. The adult, a small brown snout-beetle, and th larva, a green wormlike creature, usually escape notice during the first two or three years that they are present in a locality, but as soon as they begin to become numerous enough to do harm they are readily found, and their effect upon the appearance of the fields is conspicuous. Vigorous treatment is then necessary to prevent partial or total destruction of the first and second crops. The purpose of this bulletin is to show how serious the attack is to the farmer, how much territory it embraces and how it spreads, a nd to describe the insect, its work, and the methods which are effective in dealing with it.

Excerpt from Field Evaluation of Insecticides for Control of the Alfalfa Weevil in Maryland, 1962-66 From 1962 to 1966, many insecticides were evaluated for chemical control of the alfalfa weevil. Most of these are still in the experimental stage, are not registered for use on alfalfa, and are no longer of interest commercially. None of the materials applied in the fall to small plots gave effective protection-partly, we now think, because of subsequent reinfestation. The material applied in early spring that showed most promise was Niagara nia - 10242 (granular) at 1 pound per acre (82-percent control at harvest). Named compounds that consistently gave good control when applied to the growing crop during the Spring were azinphosethyl, azin phosmethyl, Azodrin, Imidan, methoxychlor, and phorate. Methoxychlor at 1 pounds per acre plus either diazinon or malathion at 1 pound per acre were the only combinations tested more than 1 year that gave consistently good results. The outstanding numbered insecticides evaluated more than 1 year included American Cyanamid e.i. 47772, Bay 25141 and 39007, Chipman rp-11974, Geigy gs-13005, General Chemical CC-6506, Hercules 14503, Shell sd-7438, and Virginia Carolina VC 3-670.
