Question

pesticides characteristics

Answer 1

characteristics of pesticides are:
1)It is used to kill rodents like rats.
2)We should minimise it's use as excessive use of this product may affect the growth of plants

Answer 2

To understand how pesticides move in the environment, one must first understand certain physical and chemical characteristics of pesticides, as well as how these characteristics determine a pesticide's interaction with the environment. Some of these characteristics are described in the Physical and Chemical Properties section (Table 1) of a pesticide's Safety Data Sheet (SDS). Other pesticide properties are found in either the SDS' Stability and Reactivity section or Ecological Information section.

Solubility is a measure of the ability of a pesticide to dissolve in a solvent, which is usually water. Pesticides that are highly soluble in water dissolve easily. Such pesticides are more likely to move with water in surface runoff or to move through the soil in water than less-soluble pesticides.

In the SDS, manufacturers use relative terms—such as miscible, dispersible, suspension, emulsifiable, and water solubility—to describe their product's solubility. Some manufacturers will use a numerical value for this description, such as 2.9 mg/L or ppm. Pesticides with a value of 100 ppm or less are considered relatively insoluble, while pesticides with values greater than 1,000 ppm are considered very soluble.
