A_ Regional Coordination Center for the Collection, Tabula- 
tion, and Distribution of Unpublished Research Data on Residual 
Pesticide Chemicals. (1) Collect data on residues of pesticides 
on file in some western experiment stations, with information on 
methods of sampling, subsampling, extraction, purification and 
analysis used in the various stations. (2) Similarly, collect new 
data on pesticide residues and on procedures used in collection. 
(3) Collect other pertinent data on pesticide residues and methods 
for obtaining, when such information from western sources is 
scanty. (4) Establish uniform method for reporting and tabulating 
data on pesticide residues. (5) Distribute tabulated data to 
western experiment stations, and other proper authorities. (6) 
Promote exchange of information on residue problem from and to 
coordination center, etc.

Persistence of Pesticide Residues Under Mountain Climatic 
Conditions. Learn (1) toxic residues resulting from recommended 
spray programs on alfalfa, apples, pears, tomatoes, potatoes and 
green beans; (2) dissipation of chemical residues fcr the various 
insecticides used under field conditions. (3) Develop phases con- 
cerned with toxic residues for projects now in force, evaluate 
insecticides on principal orchard, potato, tomato and bean pests.

A Study of the Effectiveness of Insecticides To Control Forage 
Insect Pests, and cf the Residues Rema on Alfalfa Followin 
Their Use. (1) Evaluate the effectiveness cf some new insecticides 
in controlling forage insects. (2) Learn timing and rates of appli- 
cation for effective control. (3) Learn residues remaining on alfalfa 
at harvest following foliar application of insecticides. (4) Estab- 
lish curves for disappearance of residues by analyzing samples taken 
at intermediate stages between application and harvest.

Relation Between Conductivity of Apples and Flavor. Compare 
conductivity at harvest of apples treated with different pesticides 
and flavor evaluation of the fruit by taste panels.

Analytical and Sampling Procedures for Determining Parathion, 
DDT and Other Organic Insecticide Residues cn Vegetables. To (1) 
make lab evaluation, modification and adaptation of current chemical 
procedures involved in the determination of parathion, DDT and other 
related organic insecticides on specific vegetable crops; and (2) 
develop valid and practical field sampling procedures.
