Spray Drift Control Additive
That can include many different functions from improving the coverage of an application to spray drift reduction to water conditioning and other functions.
Spray drift control additive. Provides information about pesticide spray drift including problems associated with drift managing risks from drift and the voluntary drift reduction technology program that seeks to reduce spray drift through improved spray equipment design. A number of drift control methods are available to applicators. In summation wolf reminds applicators that all of these practices are good at reducing the potential for spray drift but only if they aren t chosen selectively. Then too they pay careful attention to their location for instance one.
Some farmers rather than use a drift reduction nozzle prefer to add a drift retardant. Adjuvants are used to modify the physical characteristic s of a liquid spray application to improve its performance. Activator adjuvants are by far the most common type of additives used to enhance herbicide performance. Drift control agents thickeners modify spray characteristics to reduce spray drift usually by minimizing small droplet formation.
According to wolf this could include the use of shields air assist or pulse width modulation or drift reduction additives such as adjuvants. They include new drift reducing nozzles shielded spray booms and drift control additives. Alligare drift control lessens the chances of drift and boosts pesticide performance by binding small spray particles together into larger droplets which are more capable of hitting their intended target. The new nozzles and additives increase drop size and reduce the fine drops while the shields contain the fine drops inside the shield.
Squall is a patented additive to reduce spray drift and improve the deposition on the leaves. My biggest concern with drift retardants is using too much. An extended range flat fan nozzle will give me slightly better weed insect or disease control depending on the pesticide i m using. Frank schumacher manager of mountain view co op black eagle mt says teams at his company s nine locations focus on carefully designing equipment systems choosing nozzle tips using drift control additives watching wind strength and timing sprays precisely.
Use a drift retardant if necessary. Drift inhibitors are generally polyacrylamide or polyvinyl polymers to increase droplet size.
