S. C. The Tolerance of Weeds and Pasture Grasses for Various Herbi- 

 cides, with Especial Reference to Horsenettle (Solanum carolinense ) 

 and Sandspur (Cenchrus Spp .). Develop chemical control for: sand- 

 spur in sandy soil pastures, lawns and parkways by means of pas- 

 ture plot experiments and by herbicidal applications to greenhouse- 

 grown sandspur plants; horsenettle in permanent summer pastures by 

 suitable pasture plot experiments and by means of greenhouse ex- 

 periments in which age at which horsenettle tissues are most re- 

 sponsive to herbicides.

Texas Control of Weeds and Improvement of Grasses on Ranges . To 

 (1) assemble and incorporate all pertinent data obtained to date 

 on studies under former projects l|l5 and 389; (2) learn relative 

 value of certain range management practices for bitterweed control; 

 (3) learn effect of certain range management practices on native 

 vegetation and production of livestock and livestock products: (k) 

 learn desirability of deferred rotation grazing as compared with 

 continuous grazing; and (5) learn value of mechanical and chemical 

 methods for bitterweed control.

Va. Control of Undesirable Plant Species in Pastures and Other 



Non-Crop Areas . To develop (1) safe and economical chemical 

 methods for removing undesirable annual and perennial weeds from 

 pastures and lawns, (2) methods for killing unwanted woody plants 

 growing in wood lots, fence rows and rights-of-way.

Ga. The Use of Chemicals for Weed Control and Defoliation of Crop 



Plants^ To determine (1) most economical method to control weeds 

 in cultivated crops; (2) most satisfactory and economical method 

 to control weeds in small grain and sod crops; and (3) effective- 

 ness of materials used for defoliation of cotton and other crops 

 and what effect chemicals have on quality and quantity of crops 

 harvested.
