Specific objectives of this study were to determine the effects of various drift retardant chemicals (Direct, Driftgard, Formula 358, Nalco-trol, and Target) on droplet size, spray pattern, and spray drift reduction. The results of this study indicated that, at recommended rates, Nalco-trol provided the largest increase in volume median diameters of the sprays followed by Direct, Target, Driftgard, and Formula 358. In general all drift retardants created patterns with greater volume toward the center than that of water only. Cumulative deposits beyond 0.5 m downwind increased for all drift retardants when the wind velocity was increased from 2.0 to 4.0 m/s. The least amount of downwind deposit beyond 0.5 m at 4.0 m/s was with Nalco-trol followed by Target, Driftgard, Direct and Formula 358. In general, a comparison of the spray deposits from mixtures containing drift retardants on horizontal targets and vertical strings indicated that Nalco-trol and Target were the most effective in reducing spray drift followed by Direct, Driftgard, and Formula 358.
