Abstract
The effects of fall- or spring-applied tillage practices on adult emergence of a sunflower seed weevil, Smicronyx fulvus (LeConte), were evaluated over a 2-year period. Weevil emergence counts indicated that fall or spring moldboard plowing after a sunflower crop reduced adult emergence by 29 to 56% over a 2-year period compared with the untilled control. Spring chisel plowing reduced emergence 36 to 39%. The planting of wheat, corn, or sunflower on land heavily infested with sunflower seed weevil larvae had no significant effect on the timing or number of emerging weevils.This publication has 1 reference indexed in Scilit:
