Determination of Pesticide Residues. (1) Learn residues 
of insecticides, fungicides, and herbicides on fruit, vegetables, 
forage, livestock and poultry products following application of 
these materials. (2) Develop new or improved analytical methods 
for determining pesticide chemicals in residues. 
Agr. Biochem. 1308 (NE-36) 
Pesticide Residues. Evaluate (1) endrin residue on pine- 
apple fruit and juice; (2) parathion residue on acerola or West 
Indian cherry and juice; (3) make correlations between chemical 
and bioassay methods for determining endrin residues on pineapple 
fruit and juice and parathion residues on acerola cherry and juice. 
Soils 104, (S-22) 
Pesticide Residues in Relation to Crop Production. (1) Learn 
pesticide residues on forage crops under field conditions. (2) 
Develop methods for separating respective residues resulting from 
mixtures of pesticides applied to forage crops. (3) Modification 
of chemical and biological assay methods for pesticide residues.

Pesticide Residues - Determination; Effect on Plants and 
Soils.--A. Biological and Chemical Determinations of Pesticide 
Residues in the Soil.--B. Effects of Pesticide Residues on Plants 
and Soils. To (1) standardize and apply biological and chemical 
methods of pesticide residue analysis with chemical analyses; 
(2) to integrate results from biological and chemical analytical 
techniques; and (3) evaluate effects of pesticide residues on 
plant growth, plant products and soils.

Determination of Residues from Certain Pesticides When 
Applied for the Normal and Experimental Control of Insects and 
Diseases of Fruits and Forage Crops in Tennessee. Learn (1 
residues from Captan when applied to strawberries, apples, and 
peaches under various conditions for disease control; (2) amounts 
of Toxaphene, DDT, and Demeton residues on strawberries when 
applied under various conditions for control of insects; (3) resi- 
dues of Toxaphene, DDT, and Dieldrin on alfalfa when applied under 
various conditions for control of insects. (4) Develop or verify 
recommendations for use of pesticides under state conditions re- 
sulting in meeting tolerance regulations for food and forage crops.

Pesticide Residues on Forage, in Dairy and Poultry Products, 
and in Meat. To learn (1) residues of insecticides in raw whole 
milk following their use on cows and in barns; (2) residues of in- 
secticides on forage, especially alfalfa, resulting from insect con- 
trol programs; (3) residues in milk following feeding of insecticide 
treated hay; (4) residues in certain poultry products following inges- 
tion of insecticides or their use in and around poultry houses.
