Adjuvantes na pulverização agrícola

Abstract

Adjuvant is the product used in admixture with products formulated to improve spraying. The use of adjuvants in the application of agricultural pesticides becomes essential for acquiring better results of action of the active ingredient, as well as, to cause smaller environmental impacts and to optimize the economic resources. Therefore, the present work aims to identify the efficiency of the use of adjuvants in agricultural spraying, analyzing the dispersion index of the product, the coverage rate and the volumetric average diameter of the droplets. To obtain the results, four types of adjuvants were used: surfactant, mineral oil, vegetable oil and drift reducer. The work was carried out in the pre-sowing desiccation of the soybean crop, remaining in white oats. According to the data obtained it has been found that the Dash® surfactant adjuvant, which is based on methyl, methyl palmitate and solids, has the best results in spraying the syrup.
