precautions while using herbicide

A proper nozzle flood jet or flat fan should be used.
Only appropriate amounts of herbicide should be used. If herbicide is used more than the recommended dose, the crop may also be damaged in addition to weeds.
Weedicides should be sprayed at the appropriate time. If spraying is done before or after time, there is a possibility of loss rather than profit.
The correct amount of weedicides and water should be used to prepare a solution of herbicide.
Do not spray the same herbicide chemical again and again on crops, but do it interchangeably, otherwise, weeds may produce immunity against herbicide.
There should be sufficient moisture in the soil at the time of spraying and spraying should be uniform throughout the field.
The weather should be clear at the time of spraying.
If the medicine has been bought more than used, keep it in a cool, dry, and dark place and take care that children and animals do not come in contact with it.
While using it, make sure that the chemical does not fall on the body. Use special dress gloves, goggles for this, or if not available, wrap polythene in the hand and tie a towel on the face.
After use, destroy empty containers and press them into the soil. Clean it and do not use it to keep food items.
A person who sprayed the medicine must wash hands and mouth thoroughly with soap after spraying.
