 Seven systemic insecticides are currently being used for cotton 'nsect con- 

 trol in the United States. However, only two of them, disulfoton and pho- 

 rate, are being applied so that true systemic action occurs; these two mate- 

 rials are applied as in-furrow and seed treatments and occasionally as side- 

 dress treatments, primarily for the control of thrips, aphid and mites. 

 Of a number of experimental compounds being evaluated for control of cotton 

 insects, a new carbamate compound, Temik, appears to be of particular interest. 

 Temik shows considerable promise for control of thrips, aphid, spider mites, 

 cotton fleahopper, lygus bugs, and possibly boll weevil when it is applied 

 as an in-furrow or sidedress soil treatment. The recently developed tech- 

 nique of stem treatment is a method of applying systemic insecticides effi- 

 ciently in spite of soil and moisture conditions that are unfavorable for 

 sidedress soil treatments. Stem treatments of systemic insecticides have 

 been used to control aphids, spider mites, cotton fleahopper, and lygus bugs 

 in field experiments.

Considerable evidence is available to indicated that insecticides can be utilized 

 more effectively and that biological agents can be used to control insect pests. 

 Additional research on formulations and selective Insecticides and the develop- 

 ment and/or implementation of management techniques satisfactory for Implementing 

 more desirable use patterns should result in more desirable uses of insecticides.
