Field studies were conducted to determine the effect of adjuvant and nozzle on droplet size, distribution and coverage. Tracer™ was applied in water alone, or in water with the addition of one of the following adjuvants: Crop oil concentrate (COC), wetter/spreader (X-77), or a combination product (an organo-silicone and methylated crop oil). Spray distribution patterns were evaluated using water sensitive cards. Analyses of the water sensitive cards revealed no significant differences using Tracer alone or with adjuvants. Of the 18 trials, statistical analyses found no significant trends on the following variables - ground vs. air applications, temperatures, humidity levels, or nozzle types. In most cases, the addition of an adjuvant is not that important, however, in cases with low volumes it can provide some benefit. Given the wide range of available adjuvants and pest/crop situations, these products should be used based on local experience. Further, the addition of an adjuvant does not appear to hurt the penetration, coverage or residual of Tracer.
