Air-carrier spray equipment: Economical and effective in applying concentrated spray mixtures
by Arthur D. Borden
| Full text HTML  | PDF  
Not available – first paragraph follows: Field investigations with different spray methods have shown that heavy applications—1,100 gallons per acre on average sized trees, to 2,500 gallons on larger trees—are not necessary to obtain satisfactory deposits of the spray chemicals and control of the insects and plant disease problems.
