What is a wettable powder?

1. A dry pesticide formulation in powder form that forms a suspension when added to water.

2. A substance or agent able to produce abnormalities or defects in living human or animal embryos or fetuses. Not usually inheritable.

3. A liquid pesticide formulation that dissolves in water to form a true solution.

4. Weather related event that occurs when cool air is trapped near the surface under a layer of warm air.

The correct answer is: A dry pesticide formulation in powder form that forms a suspension when added to water.

A wettable powder is a type of pesticide that comes in powder form and becomes a suspension, or mixture, when added to water. The incorrect options refer to unrelated concepts, such as teratogens (option B), liquid pesticides (option C), and meteorological events (option D). These choices are incorrect as they are not relevant to the definition of a wettable powder. It is important to carefully read and consider all options before making a final selection when answering multiple choice questions.
