 Hort. 2125 



Mo. Control of Weeds in Horticultural Crops . (1) Learn weed 



control effectiveness and specificity of new herbicidal chemicals 

 being produced by industry and the tolerance of the various horti- 

 cultural crops to these materials. (2) Study translocation of 

 herbicides by radioisotope technique. (3) Learn value of mulching 

 materials in weed control and crop production,

N. Y. Herbicide Residues in or on Vegetable Crops . To determine (1) 

 (Cornell) residues remaining on or in vegetable crops resulting from the use 

 of herbicides; (2) residues in or on potatoes, dry beans, and other 

 vegetable crops, and in soil resulting from use of vine-killers, 

 sprout inhibitors, defoliants, and other plant regulators.

Ohio Eradication or Control of Weeds and Other Undesired Plants. 

 II. Chemical and Cultural Weed Control Studies with Horticultural 

 Crops. To determine (1) if any available weed control chemicals 



canbe used in conjunction with regular cultural practices to 

 solve some major weed problems associated with production of 

 horticultural crops ; (2) kind of chemical best suited for use with 

 a specific crop; (3) optimum form of chemical, time, rate and 

 method of application for each crop under field conditions; and 

 (k) through replicated field plot experiments, the value of these 

 treatments with regard to weed control, and their effect on 

 qualitative and quantitative yields of the crop plant.
