What Is the Glufosinate Dilution Ratio with Water? A Detailed Guide to the Correct Dilution Method

Glufosinate is a very good herbicide that can effectively remove wild wheat, fescue, jointed goatgrass and other annual and perennial dicotyledonous and grass weeds commonly found in orchards and vineyards, but when using glufosinate, it must be diluted with water, so what is theglufosinate dilution ratio method?

1. What is the glufosinate dilution ratio method?

For removing ordinary weeds, 200g/L glufosinate at 200ml per 30 kg of water is appropriate. For removing resistant weeds such as cogongrass and reeds, 200g/L glufosinate at 200ml per 15 kg of water is appropriate. When using glufosinate, it must never be used when crops have just emerged, and it must not be sprayed at low temperatures, so as to avoid reducing the herbicide's efficacy.

2. What precautions are there for using glufosinate?

1. It must never be used when crops have just emerged

If crops such as corn, wheat and sorghum have just emerged, they must never be treated; weeding can be done at the late seedling stage of corn. When spraying, choose a sunny, windless day and use a hood on the nozzle for directed spraying. Although glufosinate has weak systemic activity, it still has some systemic activity, so try to avoid drift onto the corn.

2. Glufosinate must not be used under low-temperature conditions

Glufosinate is generally best sprayed when the temperature reaches about 20 degrees, because as the temperature rises, the weed-killing effect of glufosinate increases accordingly. However, it is recommended to spray before 9 a.m. or after 5 p.m. to reduce volatilization.

3. Increase the amount as appropriate during the rainy season or when the weather is especially dry

During the rainy season, weeds grow quickly, so the glufosinate dosage needs to be increased as appropriate. When the weather is especially dry, the glufosinate dosage also needs to be increased as appropriate, because drought causes the herbicide to volatilize. When there is standing water in the field, the glufosinate dosage also needs to be increased; generally, increasing the dosage by 25% on top of the original amount is appropriate.

4. The amount of water used must be sufficient

At the same dosage, differences in the amount of water used will also lead to great differences in the final control effect. This is because glufosinate mainly relies on contact action, and a sufficient amount of water increases the time the leaf surface is soaked with the spray solution, greatly raising the local concentration of glufosinate within the plant.

5. Secondary dilution must be carried out

When diluting glufosinate, usually first use a small amount of water to dilute the glufosinate into a mother liquor, then use a large container to dilute the glufosinate mother liquor to the required concentration.
