The Basic Requirements and Design Principles of Mechanical 
Equipment for Control of Insects, Diseases, and Weeds. To study 
the requirement of mechanical equipment for pest control practices 
with the objective of determining basic information necessary to 
design new or to modify existing available equipment for practical 
use. To design and construct equipment for experimental use for 
the purpose of determining practical control measures and suitable 
machinery. Assemble information necessary to design sprayers for 
weed control in row crops, open fields, and lawns. Machines to be 
capable of applying concentrated herbicides at the rate of as low 
as one gallon per acre. Experimental machines built and used for 
field tests. Recognized procedures for plot testing shall be 
followed. Cooperating Dept. will provide the herbicides and super- 
vise the layouts of plots and measurements of material efficiency.

Insecticide and Fungicide Residues in Forage and Animal 
Products. (1) Develop sampling techniques for insecticide and 
fungicide residues of forage crops and learn what constitutes 
an adequate sample, how it should be chosen, harvested and handled. 
Learn (2) accumulation of fungicides in soils and their effect on 
forages. Determine: (3) insecticide and/or fungicide residues 
of forage and silage from present recommended schedules as applied 
by growers and correlate residues with different types of formula- 
tions, application methods, dilution, pressures etc.; (4) effects 
of curing hay and methods of handling and storage of it on resi- 
dues and residue losses. Study (5) timing methods of application 
of insecticides based on plant height, arbitrary application 
schedules or numbers of days to optimum date of harvest and corre- 
late these facts with insect control and residues at harvest; (6) 
effects of growth and weathering on insecticide residues of various 
formulations on forage, peavine and corn silage. Determine: (7) 
levels of insecticide and/or fungicide residues that may be fed 
safely to cattle without contamination of milk or meat; (8) fungi- 
cidal residues at time of pasturing, in hay or ensilage, and at 
feeding; (9) levels of residues that can be safely fed to poultry.

Pesticide Residues on Apples and Grapes at Harvest and at 
Intervals During the Growing Season. Learn residues at harvest on 
apples and grapes grown in this area, especially where mixed pesti- 
cides have been applied. Learn interval between last application 
and time of harvest so that federal tolerances can be met.
