Controlling spray drift of pesticides with self-emulsifiable esters

a technology of self-emulsification and esters, which is applied in the field of control of spray drift of pesticides with self-emulsification esters, can solve the problems of many commercially available drift retardants that do not work with many aerially applied herbicide tank mixtures, and the application restrictions of sensitive crops, etc., to achieve the effect of reducing spray drift, reducing spray drift, and reducing spray dri

Description

[0001] This application claims the benefit of U.S. Provisional Application Ser. No. 61 / 110,060 filed on Oct. 31, 2008.BACKGROUND OF THE INVENTION

[0002] The present invention concerns a novel method to reduce spray drift during the application of agricultural chemicals by incorporating a self-emulsifiable ester into the liquid to be sprayed. Agricultural spraying by economical and available technologies uses hydraulic spray nozzles that inherently produce a wide spectrum of spray droplet sizes. The potential for these spray droplets to drift from the initial, desired site of application is found to be a function of droplet size, with smaller droplets having a higher propensity for off-target movement. Significant research efforts, involving numerous field trials, wind tunnel tests and subsequent generation of predictive math models have led to a greatly enhanced understanding of the relationship between spray droplet size and potential for off-target drift. Although other factors such ...
