I. Tomatoes and Related Crop Insects 
Ind. Insect and Related Problems in Food Processing Plants, 
with Special Reference to Tomato Cannerjes. 1) Learn 
species of insects constituting problems in and about 
plants, and factors contributing to intensity of occurrence. 
(2) Develop improved methods of control measures for 
protection of foods from harvest through to finished 
product. (3) Study methods of reducing residue hazards 
resulting from application of insecticides. (4) Discover 
improved methods for control of obnoxious insects 
developing in waste products of processing.

Moe Commercial Culture of Truck Crops and Greenhouse 
Vegetables. e. Cultural Practices for the Processing 
Tomato Crop in Southwest Missouri. To (1) conduct a 
tomato improvement project similar to that of last year 
in 4 additional counties; (2) concentrate experimental 
plots at canning centers on several different soil types; 
(3) field test several new insecticides and fungicides; and 
(4) study graded quality with more emphasis than in the past.

Ohio Disease and Insect Resistance in the Tomato: A Breeding 
Project. To (1) develop varieties of tomatoes, resistant to 
Fusarium wilt, leaf mold, mosaic, and Septoria and 
Alternaria leaf spots by combining genes for resistance in 
wild species with genes for desirable qualities in domestic 
species; (2) study fungi causing diseases from standpoint of 
physiologic races and their distribution; (3) isolate 
differential accessions for identification of physiologic 
races of above disease producing organisms; (4) evaluate 
developed accessions for resistance to insects which attack 
glasshouse- and field-grown tomatoes; and (5) study nature of 
resistance to disease to determine loci on chromosomes of the 
genes which govern resistance and to conduct embryological 
studies to determine cause, nature, and degree of incompatibility 
in interspecific hybrids within genus Lycopersicon.
