Method of proportion of glyphosate to water

Glyphosate is a good herbicide, which can effectively remove annual and perennial dicotyledons and Gramineae weeds in orchards and vineyards such as wild wheat, fescue, leaf corn, etc., but if you use glyphosate, you must dilute it with water. what is the ratio of glyphosate to water?

What is the method of the ratio of glyphosate to water?

For the removal of common weeds, 200g/L 's glyphosate is suitable for about 30 kg of water per 200ml. Except for the resistant weeds such as white grass and Reed, the glyphosate of 200g/L should be mixed with water about 15 kg per 200ml. When using glyphosate, crops should not be used at the beginning of seedling emergence, and should not be sprayed at low temperature, so as not to reduce the efficacy.

Second, what are the points for attention in the use of glyphosate?

1. Crops must not be used when they first emerge.

If corn, wheat, sorghum and other crops have just emerged, do not use them. Weeding can be carried out in the later stage of corn seedlings. When spraying, it is necessary to choose a cover on the sprinkler when there is no wind on a sunny day. Although the internal absorption of glyphosate is not strong, it still has a certain internal absorption, so try not to drift to the corn.

2. Glyphosate can not be used at low temperature.

Glyphosate is generally best sprayed when the temperature reaches about 20 degrees, because the germicidal effect will be improved with the increase of temperature. However, it is recommended that you spray before 9am or after 5pm to reduce volatilization.

3. Add as appropriate in rainy season or especially dry weather.

In the rainy season, weeds grow fast, it is necessary to increase the dosage of glyphosate as appropriate, and when the weather is especially dry, it is also necessary to increase the dosage of glyphosate, because it will volatilize when it is dry. When there is stagnant water in the field, it is also necessary to increase the dosage of glyphosate, generally, it is more appropriate to increase the dosage by 25% on the basis of the original dosage.

4. Water consumption must be sufficient

At the same dose, the final control effect will be very different because of the difference in water consumption. Because glyphosate mainly depends on contact effect, sufficient water consumption increases the soaking time of leaves and greatly increases the concentration of local glyphosate in plants.

5. Be sure to carry out secondary dilution

When diluting glyphosate, it is usually diluted to the mother solution with a small amount of water, and then diluted to the desired concentration in a large container.
