True or False? Wettable powders require agitation and have low phytotoxicity.

Wettable powders indeed require agitation to ensure they are fully suspended in the solution before application. This agitation allows for an even distribution of the active ingredient throughout the liquid, preventing settling and ensuring effective coverage and performance. When properly mixed, wettable powders can be effective and minimize the risk of phytotoxicity, which refers to damage or injury to plants resulting from chemical exposure.

Additionally, many wettable powders are formulated to be low in phytotoxicity, making them suitable for use without highly damaging plants when applied correctly. Hence, stating that wettable powders have low phytotoxicity aligns with their commonly desired characteristics, particularly when applied per label instructions.

The assertion provided in the correct answer captures both the requirement for agitation and the characteristic of low phytotoxicity for many wettable powder formulations, thereby making it the accurate choice.
