What should be paid attention to when using glyphosate series herbicides? Glyphosate series herbicide is a kind of organophosphorus, low toxic, internal absorption and transmission type broad-spectrum post-bud herbicide, which can effectively control annual and perennial malignant weeds. In the use of glyphosate herbicides, if not used correctly, it will often cause drug damage to crops or can not give full play to the efficacy of glyphosate. In order to help the broad masses of farmers to use glyphosate herbicides scientifically and rationally, on August 20, 2010, I trained the science and technology demonstration households of Hamantuan Group on the correct use of glyphosate herbicides. Points for attention: 1. Choose a sprayer with a hole diameter of about 1 mm to apply the spray so that the droplets are small and uniform and facilitate the deposition of weed blade surfaces; 2. Add half the amount of water first, and then add the chemical to stir evenly, then add the other half of the water to stir evenly before spraying. 3. Glyphosate is a destructive herbicide. When spraying, use a low-pressure sprayer or put a protective cover on the sprinkler to prevent the pharmaceutical industry from drifting to the stems and leaves of crops, so as to avoid drug damage. 4. Glyphosate is easy to "passivate" and lose its activity in the presence of soil. muddy water and sewage should not be used in the pharmaceutical industry, and there is a lot of dust on the leaves of roadside weeds, so the dosage should be appropriately increased. 5. Rainfall within 4 hours after spraying will reduce the efficacy and must be re-sprayed; 6. Do not mow, graze and turn the ground within 3 days after applying glyphosate; 7. When the density of weeds is high, the dosage and water consumption of spraying should be increased appropriately; 8. Glyphosate should not be mixed with other herbicides such as paraquat, so as not to reduce the activity and affect the efficacy. Through the training, the demonstration households have mastered how to apply glyphosate correctly, and at the same time, it has also led other farmers to use glyphosate series herbicides scientifically and rationally.
