Waiting period of commonly available Insecticides, Fungicides, Nematicide & Bio-pesticides in Nepal

WAITING PERIOD

Introduction:

Pesticide is chemical which includes all of the following: herbicide, insecticides (which may include insect growth regulators, termiticides, etc.) nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, antimicrobial, and fungicide. The most common of them  are herbicides which account for approximately 80% of all pesticide use.  Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects.

However, pesticides are always hazardous to human health. They have residual effect in human health even causing cancer at some circumstances. They are necessary evil for plant crop so as to get rid of insects, fungus, nematodes and diseases.

Waiting period is the duration between the application of any type of pesticide to the harvest of the crop from  the same field. It is necessary to wait until the period passes so that no health hazardous will occur in human body due to residual effect of chemical. There are specific waiting period of every pesticide after application to consumption of crops.
