Show COUNTY AGENTS NOTES What can I use to spray my alfalfa to control the weevil? This is a question most ranchers are asking these days. Several of the chemicals that were very effective in controlling adult weevil early in the Spring have been removed from the approved list ofchem-icals. Weevil damage to alfalfa has been serious during the past few years. To date there is no approved early Spring spray that will control the adult alfalfa weevil before she lays egga. Our recommendation is to wait until the larvae hatch in the growing alfalfa. If the hay can be cut a bit early and the fields sprayed between first and second cutting the second crtn can be saved. There are several good insecticides that can be used for the larvae, such as Methyl Pa-rathion, Malathlon and Guth- ion. |
