Rice water weevil adults feed on rice leaves, causing longitudinal scars. Some people describe the white stripes on plants as “painted” rice. If the weevil population is large enough on small seedlings, this can result in death of the plant. Immediately after the application of flood water to the rice field, adults will begin laying eggs just below the surface of the water. If you did not treat your rice with Dermacor X-100, you need to use an insecticide that will kill adults before they have the chance to lay eggs. Complications with crawfish production Remember that if your field is located near a crawfish pond you need to use extreme caution when applying insecticides by plane or ground rig for RWW control. Pyrethroid insecticides (Karate and Mustang) are extremely toxic to crawfish. Trebon 3G is also toxic to crawfish, but it is a granule and is less likely to drift into nearby ponds. Do not apply insecticides to a rice field that will be used for crawfish cultivation. Be sure to
