Harm Caused by the Herbicides

Harm Caused by the Herbicides

Residues of various weedicides and insecticides often accumulate in agricultural soils rapidly. Insecticides are designed to kill insects. As such they may not be toxic to plants. On the contrary to it, some herbicides differ from insecticides in killing both desirable species as well as the intended target. They may adversely affect such soils microbes as nitroes fixing blue-green algae and bacteria. This, in turn, may impair the growth and production of higher plants.
