Inert ingredients can be many substances, like water, kerosene, emulsifier if the pesticide is a liquid. A powder pesticide will typically contain vegetable matter such as corn cobs, clays or powdered minerals.

During their production a large volume of exhaust is generated and needs to be treated. Generally first dust & particle removal apply followed by physical and chemical absorption process.
