Some crops can be damaged or killed by traces of phenoxy herbi- cides that are left in the sprayer after cleaning. Before applying fungicides or insecticides to crops with equipment that has been used for herbicides, test the equipment for herbicide traces. Fill the tank with water and spray a few of the crop plants. Sensitive plants such as tomato, cotton, and tobacco are good test plants. Wait a day or two after spraying. If the crop plants show no distorted growth after this pe- riod, the equipment can be used safely for spraying the crop. If the plants are distorted, then clean the spray equipment again. Re- test the equipment for cleanliness before using it on crops. For greatest safety with sensitive crops, apply fungicides or insecti- cides with equipment that has not been used for applying herbicides. You can clean spray equipment quickly with a suspension of acti-. BN-11740-X The right half of this field was sprayed with 2,4-D before the corn or weeds emerged. The left half of the field was not treated. 10.
