small concentrations of GS-13005 were translocated to new plant growth and 

 none was detected in the fruit. The highly toxic oxygen analog of GS-13005 

 was found in extracts of treated plants and insects but not detected in 

 the urine of white rats.

 aldehyde 0;-(methylcarbamoyl)oxime) in cotton plants and soil in the 

 field. J. Econ. Entomol. 61: 1598-1602. 



Metabolism of S^^-labeled UC-21149 (2-methyl-2-(methylthio) propionaldehyde 

 O-(methylcarbamoyl)oxime) in cotton plants and its fate in soil under normal 

 field conditions was investigated. After 2 days the compound was completely 

 metabolized in individually treated leaves, primarily to the toxic sulfoxide 

 derivative 2-methyl-2-(methylsulf inyl) propionaldehyde O-(methylcarbamoyl) 

 oxime. Once formed, the sulfoxide was relatively stable; the biological half- 

 life was about 1 week and 14% of the applied dosa was still in this form after 

 32 days. Studies of translocation demonstrated that there was little movement 

 of radioactivity from treated leaves to untreated areas of the cotton plants. 

 UC-211A9 and at least 10 of its derivatives were detected in treated soil. Of 

 these, the sulfoxide was usually the dominant product; UC-21149 was essentially 

 depleted after 1 week. After 8 weeks, 86.3% of the applied radioactivity was 

 lost from the treated soil, either by volatilization or by movement as a result 

 of moisture from rainfall and irrigation.

 Boll Weevil With Pheromone. Tex. Agric. Exp. Stn. Res. Monogr. 8, pp. 1-9. 



Grandlure, the synthetic pheromone of the boll weevil, Anthonomus grand is 

 Boheman, is a mixture of four highly volatile chemicals. Both sexes respond 

 to the attractant, and there is evidence that it may function either as an 

 aggregation of sex pheromone. The Environmental Protection Agency has issued
