M inn. Cause and Control of Biological and Chemical Deterioration 

 of Agricultural Products in Storage. — I. Soybeans. Corn and 

 Cereal Grains . To determine (1) mold population of commercial 

 lots of corn, soybeans, and cereal grains of different market 

 quality; (2) main factors influencing growth of molds on storage 

 grains; and their effects; (3) if mold assays might be useful 

 as additions to criterium of quality; and (4) which promising 

 compounds can be used as inhibitors of molds on stored seeds.

Nebr. Physiologic Studies of Obligate Parasitism, with Special 



Emphasis on Diseases Caused by Rust . (1) Develop quantitative 

 techniques for inoculation of obligate parasites, maintenance 

 of host and parasite under controlled conditions, determination 

 of extent of development of parasite; (2) study specific metabolic 

 systems responsible for obligate nature of parasitism; (3) 

 determine metabolic changes in host during, and as result of, 

 infection, particularly changes which may be associated with 

 resistance or susceptibility of host; (U) from 2 and. 3, effect an 

 inquiry of possibility of effective chemotherapeutic control of 

 obligate parasites of economic importance; (5) establish quanti- 

 tative, rapid, and reliable methods for evaluating chemical com- 

 pounds as possible chemotherapeutants.

N.J. A Study of the Post- Harvest Improvement of the Marketable 

 Quality of Fresh and Processed Food . To (1) prevent fruit fly 

 infestations developing on harvested crops such as tomato, pepper, 

 peach, etc. from the time they leave the farm until processed or 

 sold at retail; (2) remove dead bodies of insects adhering to 

 vegetables and which have been killed by insect parasites and 

 entomophagous fungi; (3) study pest problems of roadside fruit 

 and vegetable stands including wasps and bees which puncture skin 

 of fruit, beetles as pests of ripe fruits, solution of the problem 

 if insects attracted to stands at night by their lights, etc.; 

 (A) prevent decay and contamination of harvested, perishable food 

 caused by fungi or bacteria until products preserved or consumed; 

 and (5) determine effect of the treatments for decay and disinfection 

 on the quality of the products so treated.
