Abstract

Three methods of mixing fertilizers and insecticides were used. The first was the addition of formulated insecticide to the aqueous solu­tion of foliar fertilizer, the second was the addition of formulated fertiliz­er to the aqueous emulsion of the insecticide, and the third was the di­rect mixing of both formulations then dilution by water. Physical properties such as emulsion stability, foam, electrical conductivity, viscosity and surface tension were studied at aerial dilution rate for insecticides alone and their binary mixtures with foliar fertilizers under the studied methods of mixing. Data showed that the compatibili­ty was highly affected with the method of mixing , a matter necessitat­ing the mention of the method of mixing in the application instructions.
