It is true or false that pesticide chemicals often need to be combined with diluents, solvents, wetting agents, and stickers?

The assertion is true because many pesticide formulations require the addition of diluents, solvents, wetting agents, and stickers to enhance their effectiveness and application. Diluents are used to reduce the concentration of the active ingredient, making it safer and easier to apply. Solvents can help dissolve active ingredients for better coverage and absorption. Wetting agents assist in spreading the pesticide over surfaces, preventing beading and ensuring even coverage on plant surfaces. Stickers help the pesticide adhere to the surfaces being treated, improving its longevity and effectiveness by reducing the loss from weather conditions such as rain or wind.

In practice, the specific needs for these additives can vary depending on the type of pesticide being used, but the general principle is that enhancing the stability and efficacy of pesticide applications often requires such combinations.
