How to correctly use glyphosate in vegetable plots?
Use of glyphosate in vegetable plots
(Agricultural Wealth Network) "Can the non-selective herbicide glyphosate be used in vegetable plots?" Farmers have long been puzzled by this question. The answer is yes, but special attention must be paid to the application technique, otherwise it is easy to cause herbicide damage to vegetables!
Glyphosate, also known as Roundup, Zhencaoning, Nongminle, etc., is an organophosphorus herbicide whose active ingredient is glyphosate. It has a systemic, broad-spectrum, non-selective herbicidal effect on weeds, is used for stem and leaf treatment, and can kill the underground parts of perennial deep-rooted weeds, but it quickly becomes ineffective upon contact with soil and has no effect on weeds that have not yet emerged.
When using glyphosate, generally wait until the weeds have all emerged, at the 4-6 leaf stage, use 0.5-1 kg of 10% aqueous solution per mu, add 100 ml of diesel oil, add about 20-30 kg of water, and spray evenly on the weed stems and leaves.
When glyphosate is used for weed control in vegetable plots, it can only be used when there are no vegetables in the plot. Per mu, 0.5-1 kg of 10% aqueous solution can be used to kill weeds such as crabgrass, annual bluegrass, spiny amaranth, and wild vetch. Use 1-1.5 kg of 10% aqueous solution to kill weeds such as nutgrass, plantain, horseweed, and fleabane. Use 2-2.5 kg of 10% aqueous solution to kill weeds such as white cogongrass, reed, lespedeza, half-edge lotus, bermudagrass, and pinellia. All are diluted with 60-75 kg of water and sprayed over the whole field.
When treating weed stems and leaves, it is strictly forbidden to let the spray solution contact vegetables and other crops, to prevent herbicide damage.
When controlling weeds in chive plots, it should be done on the same day after harvesting the chives (do not delay application to the next day). Use 41% Roundup aqueous solution; in plots dominated by annual weeds, use 0.2 L of the aqueous solution. In plots dominated by perennial weeds, use 0.3 L of the aqueous solution, dilute with 30 kg of water, and spray the solution over the whole field.
When controlling weeds in daylily plots, during the daylily flowering period, use 1-2 kg of 10% aqueous solution, dilute with 50 kg of water, and spray over the whole field. It can kill weeds such as white cogongrass, jointed paspalum, bermudagrass, and yellow (purple) nutgrass. It is safe for daylily.
When applying the pesticide, choosing a nozzle with a 0.8 mm aperture works better than the commonly used nozzle with a 1.0 mm aperture. The agent is only effective after contacting stems and leaves, so spray evenly and let the weeds be covered with the agent.
Prepare the spray solution with clean water of lower hardness. Sprayers that have been used should be repeatedly rinsed to avoid causing herbicide damage to other crops in later use. It is not suitable to mix with fast-acting herbicides such as MCPA and Gramoxone. For example, adding 0.1% laundry detergent to glyphosate, or adding 30 grams of diesel oil per mu, can both enhance the efficacy.
