CONTROL WITH INSECTICIDE 



Lindane and parathion are the insecticides recom- 

 mended for controlling the pickleworm. Lindane usu- 

 ally is most effective. 



The insecticides may be applied as dusts or sprays. 

 Dusts are ready to use when purchased. A spray is 

 prepared by mixing a wettable powder or emulsifiable 

 concentrate with water. 



Note. — Lindane spray prepared from emulsifiable concen- 

 trate is not recommended for cantaloup; it may cause unde- 

 sirable flavor. Use of lindane in any form on cantaloup, 

 cucumber, and winter squash may have a slight effect on flavor. 

 Do not use lindane in fields to be planted later to potatoes or 

 other root crops. 



A dust should contain 1 percent of either lindane or 

 parathion, and a spray should provide 4 ounces of actual 

 lindane or parathion per acre at each application. 



Forms of the insecticides that are commonly available 

 for preparing sprays are listed below; opposite each is 

 shown the amount that should be mixed with water in 

 order to prepare a spray of the desired strength. (If you 

 buy a product in which the percentage of insecticide 

 differs from the one indicated here, use proportionately 

 more or less of it.)
