What are the four main types of pesticide formulations?

The four main types of pesticide formulations are characterized by their physical states and how they can be applied or mixed with other substances. Liquid formulations are highly versatile and can easily penetrate plant tissues or react quickly with pests. Granular formulations are solid particles that can be spread on the soil or plant surfaces, offering a slow-release option for pest control. Powder formulations are fine solids that can adhere well to surfaces and are often used for application in dry conditions. Aerosol formulations are convenient for spot treatments and can effectively deliver the pesticide as a fine mist or spray.

These formulations are designed to suit different application methods and target organisms while maximizing effectiveness and minimizing environmental impact. Understanding these four types enables applicators to choose the best method for their pest management needs.
