Precautions in Herbicide Application

Read the herbicide label carefully and follow the direction on the label.

• Thin film of water should be kept in the field before the chemical application.

• Irrigations and draining the water should not be done upto 3 - 6 days in chemically treated plots.

• Herbicides should be applied at the recommended time only.

• Avoid spraying in severe sun or when the soil is dry for getting better results.

• Sprayers and sprayer parts should be thoroughly washed after using the herbicides, if the same equipment is intended for spraying the pesticides.

• Specific nozzles recommended for herbicides only have to be used.

• Better use high volume sprayers under low pressure to avoid drift and carry over of the particles in the event of using herbicides in the standing crop.

• Don't mix two herbicides that are incompatable, consult weed specialist in this aspect.

• Containers should be kept out off reach to children.

• Herbicides should be transported in tightly closed containers.

• They should be kept away from food and feed stuff in the store.

• The herbicide contamination with seed, fertilizer, fungicide and insecticide should be avoided.
