Miss. Control of Perennial Weeds, Brush Species, and Other Weeds 

 in Pastures . A. Pasture Investigations: To (1) determine 

 chemical control procedures for undesirable species in spring, 

 summer and winter pastures; and (2) study the use of chemicals 

 in the renovation and establishment of pastures. B. Perennial 

 weed study: To (1) develop methods of controlling certain specif- 

 ic perennials, such as Texas cedar, ( Eupatorium capillifolium ), 

 horse nettle ( Solanum carolinense ), wild rose ( Rosa bracteata ), 

 trumpet vine ( Campsis radicans ), and other vine species in pas- 

 tures; and (2) study chemical methods of controlling perennial 

 and annual weeds along fence rows, ditch banks and rights-of-way, 

 which might supply a source of infestation for adjacent pastures; 

 and C. Studies in Brush Control: To (1) develop chemical pro- 

 cedures for deadening brush species in areas preparatory to 

 utilization for cropping or pastures; and (2) study chemical 

 methods of controlling brush species in old and new pastures, 

 ditch banks, fence rows, canals, and rights-of-way.

Mo. Research in the Control of Weeds. — I. Control of Weeds 



(Including Woody Plants) in Pastures and Meadows, and II. Con- 

 trol of Weeds in Corn, Cotton, Cereals, Soybeans . To reduce the 

 damages to pastures, corn, cotton, cereals, and soybeans, caused 

 by weeds in their many and varied ill effects.

Nebr. Pasture Weed Control . (1) Learn degree of susceptibility of 

 desirable grassland species and weeds to application of 2,U-D in 

 pastures, effectiveness of mowing for control of broadleaved weeds 

 and weedy grasses; forage production as affected by weed control 

 and grazing intensity. (2) Compare effectiveness of mowing and 

 2 formulations of 2.U-D for control of buckbrush at different dates 

 of application. (3) Compare several formulations of 2,U-D with and 

 without additives to stimulate translocation, dichlorophenoxybutric 

 acid materials, trichlorobenzoic acid and amizol for ironweed con- 

 trol, (U) Study control of hairy chess in pastures using p-chloro- 

 phenyl dimethyl urea, phenyldimethylurea and dichloropropionic acid, 

 (5) Study control effect from dichloropropionic acid, trichloro- 

 propionic acid, and trichloroacetic acid on weedy grasses on estab- 

 lishment of spring seeded alfalfa.

Nev. The Control of Certain Weeds in Native Meadows and Pastures. 



To learn enough of ecology and responses of herbicides and mechan- 

 ical treatment of certain meadow weeds to be able to describe de- 

 pendable, feasible control measures, studying foxtail barley, 

 blue flag, and arrowgrass first, in that order.

 (Cornell) greenhouse, and field studies, safe and economic methods of weed 



control in new and established stands of forage crops and pastures 



for sound farmer recommendations.
