CONTROL WITH INSECTICIDE 



Lindane and carbaryl (Sevin) are the insecticides 

 recommended for controlling the pickleworm. Lindane 

 usually is most effective. 



They may be applied as dusts or sprays. Dusts are 

 ready to use when purchased. A spray is prepared by 

 mixing a wettable powder with water. Lindane is also 

 available in an emulsifiable concentrate for mixing 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. 



Some injury to the foliage of cucurbit plants may 

 occur if several days of rain or high humidity follow 

 the use of carbaryl. 



Each dust or spray application should provide either 

 4 ounces of actual lindane or \ pound of actual carbaryl 

 per acre. For example, apply 25 pounds of either a 

 1 -percent lindane dust or a 4-percent carbaryl dust per 

 acre. Do not exceed these dosages.
