 inhibition. (3) Develop ground spray machines for field appli- 

 cation of defoliants 8t/or 2nd-growth inhibitors, (4) Evaluate 

 different nozzles & nozzle arrangements, (5) Determine proper 

 spray volume & rate of chemical, (6) Evaluate concept of bottom 

 defoliation as an aid to reducing boll rot.

 Mississippi Delta, (4) learn effect of different openers & plant- 

 ing methods on stand & yield, (5) test, evaluate, & improve 

 equipment for field application of both liquid & granular fer- 

 tilizers, (6) design, test, evaluate, & improve machines & tech- 

 niques for the application of both pre- and post-emergence 

 herbicides, (7) test, modify & improve mechanical methods of 

 weed control, including flame cultivation equipment, & (6) 

 evaluate & improve machines & methods for controlling cotton 

 insects.
