it will not effect the growth of plants. but it will affect the health of the consumers as well as it reduces the soil fertility. but if we use natural weedicides to some extend it is okay .

Answer:
Explanation:
Weedicides, which are also known as herbicides, are chemicals which are harmful to plants. Herbicides can be selective (only kill certain types of plants) or non-selective (kill all types of plants).
Selective herbicides have different mechanisms of action. Different plants will have varying degrees of susceptibility to different mechanisms of action due to differences in absorption of the chemical and the physiology or morphology of the plant. Thus, care is taken to select the appropriate weedicides.
