Mass. Effect _of Pesticides on Quality of Fruits and Vegetables. 
To (1) develop effective methods for detecting differences in 
flavor which may be caused by pesticides applied to fruits and 
vegetables before harvest; (2) learn if flavor differences are 
due to pesticides per se, to decomposition products of pesticides, 
or changes in food product itself caused by physiological response 
of plant to the chemical; (3) correlate pesticide or decomposition 
product residuals with organoleptic analyses; and (4) learn taste 
threshold values of pesticides and/or their decomposition products.

Mich. A Study of the Anti-Mitotic Action of Various Organic Com 
pounds Used_as Insecticides, Fungicides and Herbicides. To (1) 
assess antimitotic and potential mutagenic action of compounds 
used in insect, fungus and weed control where previous field or 
chemical studies may suggest that they have such activity; and 
(2) classify active compounds as to type of antimitotic activity 
shown on basis of established reactions.

Miss. Phytotoxicity of Insecticides. To determine toxicity of 
certain chlorinated hydrocarbons, formulated for insecticidal 
use, upon growth and quality of vegetable crops grown on same 
plots for several years and sprayed with recommended strengths 
of the materials.

Action of Toxic Agents. To study the exoskeletal composition of 
grasshoppers.

N. J. Biochemical Research in Insecticides and Their Supplements 
Used Under New Jersey Conditions. (1) Develop improved formula- 
tions of insecticides; conduct experiments with newer systemics. 
(2) Learn rate of decomposition of insecticides accumulating in 
soil, either from direct application, or from sprays and dust; 
learn longevity of insecticide residues on sprayed and dusted 
cropSe (3) Study conditions and factors in formations responsi- 
ble for producing disagreeable taste in tubers and other crops.

N. Je Fundamental Physiological Studies of Mechanisms of Insecti- 
cidal Actions. To study modes of action of various types of 
insecticides and investigate mechanics of resistance so it will 
be possible to select materials which will circumvent mechanisms 
of resistance and to introduce chemicals which will inhibit 
detoxifying enzymes, thus reducing the insect to its former 
level of susceptibility.
