Similarly, wide spread practical use of biological control agents will require 

 the deve:opment of predictable and economical methods of mass production and 

 distribution of these agents as well as the development of management systems 

 in which these more sophisticated control methods can be utilized economically.

Although systemic insecticides are available that will provide effective con- 

 trol of many of the pests on cotton, it is important that their use be planned 

 afcer considering the entire cotton insect complex. For instance, the boll- 

 worm and tobacco budworm are becoming increasingly difficult to control. 

 Since systemic insecticides may Increase bollworm and budworm populations due 

 to destruction of beneficial insects and their food, the advantages and possible 

 disadvantages of applying systemic insecticides should be carefully evaluated 

 before they are used.

Aldicarb, an effective new tool for controlling cotton pests, is now available 

 for use by cotton producers. Like all other production tools, it has its ad- 

 vantages and- disadvantages including the economics Involved before making de- 

 cisions on when and where it should be used.
