R. I. Stereochemical Basis of Fungitoxic Action . To (l) determine 

 molecular configurations which act as toxophores against specific 

 fungi; and (2) study relation of parts of the molecule, its com- 

 position and physical properties to its fungitoxicity. 

 PI. Path. 601 



S. Dak. Seed Treatment and Soil Amendments for the Control of 

 Seed Rot and Seedling Blight . (1) Learn effectiveness of 

 incorporating soil fumigants into the soil for control of 

 soil-borne diseases; (2) study seed treatment chemicals for 

 control of seed rot and seedling blight of field crops; (3) 

 search for compounds of low phytotoxicity but with long 

 residual effects against diseases in soil. 

 PI. Path. 296 



Tenn. Evaluating New Fungicides , (l) Evaluate new chemicals for 



control of plant diseases by laboratory and greenhouse screening; 

 (2) conduct limited field plot tests with those materials found 

 promising in (l) above, in order to learn phytotoxicity and 

 behavior under natural environment; (3) learn compatibility with 

 major insecticides in greenhouse and small field plots. 

 PI. Path. 140 



W. Va. The Fungicidal Efficiency and Phytotoxicity of Orchard Sprays 

 as Influenced by Methods of Application, Timing, and Environ- 

 mental Factors . (1) Study effectiveness of various spray materials , 

 mixture formulations, and methods of application on disease control 

 and phytotoxicity resulting from applications of same; (2) learn 

 spray mixture formulation, time of formulation, and method of 

 application best suited.

W. Va. Testing New Fungicides and Insecticides for Value as Pesti- 

 cides on Small Fruit and Vegetable Crops ]! To (1) compare 

 effectiveness of new fungicides and insecticides with that of 

 older pesticides in control of diseases and insects prevalent 

 on small fruit and vegetable crops in West Virginia; and (2) 

 study value of insecticide-fungicide combinations as general 

 purpose pesticides on above crops.

Wis. Fundamental Problems Associated with the Accumulation of 



Pesticidal Chemicals in Soils . To determine magnitude of 

 insecticidal accumulation in Midwestern soils, rate and reasons 

 for disappearance of typical insecticides from various soil types 

 and effect of soil-borne insecticides on soil flora and non- 

 insect fauna.
