Abstract
The adjuvant effect of several surfactants on herbicidal sprays was examined by comparing the surface properties of the formulations on solid surfaces such as Teflon, pyrexglass and orange leaf. Contact angle measurements indicated that the Teflon surface behaved almost the same as the orange leaf, whereas the pyrexglass surface was quite different from that of orange leaf. From the present study, it was concluded that the surfactant concentration around the critical micelle concentration (cmc) provided maximum spreading of herbicidal sprays at solid surfaces. Among various adjuvants, Ortho X-77 was examined with and without herbicides at several solid surfaces. The photomicrographs of herbicide solutions on orange leaf as a function of time at different adjuvant concentrations indicated that the flattening time decreased with increasing adjuvant concentration up to the cmc beyond which no significant difference in flattening time was observed.
