Kans. Accumulation and Effect of Pesticidal Residues in Soils Follow— 
ing Pest Control Practices. To determine (1) rate of insecticidal 
accumulation and disintegration in soils of various types and at various 
locations under varying climatic conditions following application of 
insecticides at normal application rates and at abnormal rates; and (2) 
effect of pesticidal accumulation in soils upon soil microorganisms and 
on agricultural crops ordinarily grown in representative localities.

Kans. Factors Influencing the Magnitude, Character and Persistence of 
Organic Phosphorus Insecticide Residues on or in Food and Forage Crops. 
Isolate, define, and evaluate the factors influencing the magnitude 
and/or persistence of organic phosphorus insecticide residues on or in 
plants and animals.

Maine The Effect of Pesticides on Quality of Fruits and Vegetables. To 
(1) evaluate some sensory techniques commonly used to learn quality of 
fruits and vegetables; and (2) learn effect of some pesticides on quality 
of selected fruits and vegetables.

Mass. Pesticide Residues on or in Agricultural Products. Make determi- 
nation of (1) pesticide residues on forage crops at intervals following 
application and at harvest; (2) pesticides in products from livestock

Mich. A _ Determination of the Possibility of Controlling Certain Economic 
Insects by the Application of Chemicals Upon or Near the Soil Surface. 
To devise methods of more certain and cheaper controls for some of the 
insects of fruit, forest nursery and nursery crops in general by deter- 
mination of effect of various insecticides on or near the ground surface 
on insects spending a part of their life cycle upon or in the soil.

Mich. The "Secondary" Effects From Soil Application of Pesticides. To 
(1) cooperate with work on Regional Project NC-19, led by Wisconsin 
Station; (2) accumulate information on hazards associated with use of 
pesticides under Michigan conditions, particularly those on soil. 
More information is needed on residues—-magnitude, persistence, effect 
on plant growth, off-taste in product, and effect on other biotic 
factors.
