A water dispersible spreader sticker adjuvant. SPREADER STICKER is designed to improve the efficacy of many pesticides by increasing the spreading and adhesion of spray deposits on leaf surfaces. Unlike conventional spreader-sticker products, SPREADER STICKER provides excellent surface tension reduction resulting in increased coverage of plant surfaces. In addition, SPREADER STICKER reduces the tendency for washoff of the spray deposit by light to moderate rainfall, heavy dews or irrigation water applied by above canopy sprinkler systems. SPREADER STICKER does not contain petroleum or vegetable based oils. Optimum application and effects, however, can be influenced by the crop, pest, spray equipment, spray volume, pressure, droplet size, spray mixture and environmental factors. Consequently, it is recommended that careful observations of the spray deposit be made and adjuvant concentrations be adjusted accordingly.
