Pesticide Residues In or On Forage Crops and in Products 
From Animals Fed These Forages. Evaluate, modify and adapt 
chemical methods of analysis for: (as) pesticides used on forage 
crops for use in learning their residues in relation to effective 
use of these chemicals in controlling insect pests; (2) learning 
pesticide residues in animal products. (3) learn if feeding of 
forage bearing pesticide residues will contaminate animal products.

Basis for Agricultural Aircraft Equipment Design. To (1) 
provide basis for better agricultural aircraft solids distributor 
design and placement; (2) provide basis for design of metering 
devices, agitators, hoppers, and power source and transmission 
systems; (3) assemble information on spray equipment and provide 
basis for combination liquid and solids dispensing equipment; and 
(4) check lab results with controlled field studies for effective- 
ness of application, performance of equipment and information on 
application requirements, including rate, distribution, coverage, 
and type of material.

Pesticide Residues in Soils Following Pest Control Practices. 
To study (1) pesticidal accumulations and disintegration in soils 
of various types following applications for pest control; and (2) 
effect of pesticidal accumulation in soils upon flora and fauna 
and on the growth, quality, and yield of crops. 
Ent. 110 (NC-=19) 
Pesticide Residues on Animal Feeds and Human Foods. To 
learn (1) magnitude and persistence of pesticides applied in 
various ways to various plant surfaces; (2) levels of residues 
in edible animal products. 
Ent. 147 (NC-33) 
Chemical Studies of Plant Protectant Residues: Methods 
of Deposition and Removal. (1) Learn best methods for producing 
and maintaining deposits of pesticides which will be most effec- 
tive for control of insects, plant diseases and weeds, (2) 
Study methods for reducing or removing pesticide residues re- 
maining on crops at harvest.

Daphnia Bioassay Procedures. (1) Learn immobilization times 
of Daphnia in relation to concentration of various chemical com 
pounds including those used in pesticides and in industrial wastes. 
(2) Develop procedures for using Daphnia in bioassay based on 
immobilization time-concentration relationships.
