NEW INSECTICIDES IN THE 1970 RECOMMENDATIONS 



Gary L . Jensen 

 Ass't. Professor of Entomology 

 University of Massachusetts 



Several of the "HARD" or PERSISTENT PESTICIDES are being omit- 

 ted from the 1970 Fruit Spray Guides. Three chlorinated hydrocar- 

 bons which will not be recommended are DDT, lindane, and dieldrin. 

 Although DDT is the most effective insectide against the tarnished 

 plant bug, there are others which can be used. Dieldrin has been 

 effective against several pests but here also there are materials 

 which may be substituted. The Commonwealth of Massachusetts now 

 forbids the use of DDT out-of-doors, and as soon as effective sub- 

 stitutes are developed, many of the other chlorinated hydrocarbons 

 will also be eliminated.
