Pesticide adjuvants are secondary products used to improve efficiency and facilitate the functions of agrochemicals, such as pesticides. Adjuvants are added to products to help the pesticide do its job and stay on target. They may be in a formulated product when it's purchased. Or, they may be added to a mixture before it is applied (tank-mixed). Pesticide are added in the pesticides to improve their performance. They are added for many reasons such as to reduce product drifting, to reduce foaming, and to control acidity, among others.
They are added prior to use or may be incorporated while formulating pesticide. Adjuvants perform multiple functions, such as ensure its uniform spread on the leaves, enhance the wettability of the crop protection chemical, increase penetration in the case of systemic crop protection chemicals, increase its compatibility with foliar fertilizer sprays, and more. Pesticide Adjuvants are also used to enhance the efficacy of pesticides and other compounds that help kill or control unwanted pests commonly found in or around crops. Activator Pesticide Adjuvants enhance the activity of a spray by boosting its performance. They can improve coverage (wetting/spreading), increase absorption/penetration of the pesticide, and promote a more consistent application. They also reduce spray drift, which may cause damage to the crop and other property. They are available for use with water and oil-soluble pesticides and are recommended on most pesticide labels. Adjuvants are usually included as part of the formulated product or added to a mixture before it is applied (tank-mixed). Silicone adjuvants are highly effective emulsifiers that allow oil and water solutions to mix easily. They help alter solubility relationships of spray solutions that greatly increase pesticide absorption. They are classified as surfactants that activate pesticides by enhancing their biological activity on pests. Defoaming adjuvants help make the pesticide less dense and water-soluble, allowing it to be more easily dissolved by crop plants. They also reduce evaporation and decrease the amount of the pesticide that is washed off of a crop plant during irrigation or rain. Pesticide adjuvants are used to improve the performance of crop growth and protection. Adjuvants can also improve the ability of a pesticide to penetrate a crop plant’s leaves or slow the pesticide’s degradation. Depending on the type of a pesticide, specific types and brands of adjuvants may be recommended. However, it is important to follow label recommendations. The Indian Government reviews registered pesticides with regard to their safety and efficacy. The approved pesticides are displayed on the official website of the Directorate of Plant Protection Quarantine & Storage.
