Effect of Pesticides 



Calif, Physiological and Pathological Problems Associated with the 

 Consumer Packaging of Table Grapes . To determine (1) rates and 

 amount of SO2 diffusing into consumer package during fumigation, 

 (2) resistance of different types of plastic films to corrosion 

 from SO2 under different moisture conditions, (3) bleaching ef- 

 fect of SO2 on wet printed package material, (h) size and shape 

 of consumer packages most suitable for clusters of different 

 table grape varieties, (3>) adaptation of cluster size and shape 

 to standard sized packages by thinning before harvest, (6) rel- 

 ative stem brownness and dryness of consumer packaged vs. stand- 

 ard shipping container packed grapes, (7) precooling rates of 

 fruit in consumer packages vs. that in standard shipping containers, 

 (8) relative amounts of shatter, and (9) relative amounts of decay.

 Effects of Control Treatments . To learn (1) effect of recommended 

 control measures for pathogenic organisms on physiology of said 

 fruits, (2) cause of post-harvest physiological disorders, (3) 

 relationship of factors favoring development of disorders, (U) 

 ways of preventing or reducing disorders, (5) ways to cause 

 growers, shippers, and processors to institute ways of eliminating 

 disorders.

Colo. 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 for the various 

 insecticides used under field conditions. (3) Develop phases 

 concerned with toxic residues for projects now in force, evaluate 

 insecticides on principal orchard, potato, tomato and bean pests.
