Adjuvants are substances that are added to pesticides to improve their performance. Adjuvants can improve the efficiency of a pesticide by helping it to better target the pest or by increasing its effectiveness at lower application rates. Adjuvants can also improve the adherence of a pesticide to the target surface, which can help to reduce the amount of pesticide needed to achieve the desired results. Adjuvants can be added to a variety of pesticide formulations, including herbicides, insecticides, and fungicides. It is important to carefully follow the manufacturer's instructions when using adjuvants, as using the wrong adjuvant or using an adjuvant at the wrong rate can potentially reduce the effectiveness of the pesticide or cause other problems.
