Minn. Movement of Natural Compounds and Agricultural Chemicals 



in Plants; Its. Direction, Modification and Mechanisms , Study 



(1) rate and direction of movement of plant metabolites from 

 leaves to other plant organs and study effect of stage of plant 

 development and of certain environmental factors as light and 

 temperature on this movement; (2) movement in plants of chemicals 

 used in agriculture as herbicides and systemic fungicides in 

 relation to normal flow of metabolites, to environmental conditions 

 and to ontogeny of plant.

Mo. The Use of Antibiotics and Antibacterial Substances in the 



Control of Horticultural Crop Diseases, a. Fire Blight and Its 

 Control J To (1) find effective and safe spray combinations and 

 formulations of antibiotics which willcontrol fire blight and 



(2) determine quantitative distribution between blight susceptible 

 and blight resistant varieties of an antibiotic substance naturally 

 occuring in apple leaves.

Mo. The Use of Antibiotics and Antibacterial Substances in the 



Control of Horticultural Crop Diseases, b. Mechanisms of 

 Resistance to Bacterial Diseases as Related to Antibiotics and 

 Substances . To (1) ascertain how much of the observed resistance 

 is attributable to conditions native to the plant and how much to 

 those conditions artifically provided; and (2) categorize the nature 

 of resistance as to effects of chemical substances per se, physio- 

 logical functions or morphological (structural) peculiarities of 

 the plants under investigation.

N. H. Fungicide Investigations . To compare some promising new 



fungicides in field and greenhouse, and to explore through new 

 laboratory and greenhouse techniques the toxicity, phytotoxicity 

 and formulations of fungicides.

N.J. Determination of Pesticide Residues on Raw Agricultural 

 Commodities . (]_) Learn residues of insecticides, fungicides, 

 and herbicides on and in forages, fruit, vegetables, and milk, 

 following application of pesticides; (2) improve current analytical 

 methods and develop new ones for learning pesticide residues on 

 and in raw agricultural commodities
