Abstract/Contents: | Presents a study conducted "to determine the effect of using drift retardant chemicals on spray pattern, droplet size and spray drift." Results indicate that "if used properly (at appropriate rates), these products indeed reduce spray drift by hindering formation of small, drift-prone droplets." States that "there are many 'drift retardant' chemicals commerically available to pesticide applicators...These products are normally some type of long chain polymer or gum that increases the viscosity of the spray mixture which result [results] in a courser [coarser] spray." Reports that "some studies have found that some of these polymers tend to be sheared by passing through a sprayer pump, as would occur in normal bypass, hydraulic mixing in common agricultural sprayers. This means that the drift retardant would lose its ability to increase droplet size - its ability to reduce drift - as the spray tank became empty." Concludes that "although drift retardant chemicals are effective in reducing the number of drift prone droplets, in most cases, it is more effective to select the proper size and type of nozzles and operate sprayers at low pressure to produce the desired drop size rather than attempt to increase droplet size with a drift retardant chemical." |
