How to use alachlor and trifluralin safely and efficiently

The use of alachlor and trifluralin as vegetable herbicides must be understood by many farmers. If you do not master the use of science, not only will not achieve the effect of killing grass, but will affect the normal growth of crops. Today, China's pesticide network Xiaobian will introduce the use methods and precautions of these two herbicides in detail:

Fluoride Fluramine is a broad-spectrum, contact-killing, and systemic herbicide . Because of its wide range of weeding and good effect, it is especially popular among farmers. Vegetables such as kidney beans, kale, lettuce, carrots, etc. can generally be treated with soil before sowing. Use 48% of Fluramine Emulsifiable Oil 150-200g per 667 square meters, add 75-100g of water and mix well. Then spray evenly with sprayer. Immediate colonization can also play a role in mixing soil.
Matters needing attention: 1 Fluorine is easy to photolysis, volatile, should be mixed in time after spraying, otherwise it will easily reduce the efficacy. The main mechanism of action of flurin is to affect the growth and transmission of weed hormones and inhibit cell division. However, weeds cannot be inhibited from germination and therefore cannot kill dormant weed seeds.
Alachlor alachlor, also known as Lasso: Otrasuo, grass is not green, is a systemic soil treatment agent, except cucumber, leeks, spinach should not use this pesticide , other vegetables can be used. Before sowing or before transplanting, 300-500g of medicine can be used per 667 square meters, 40~50kg of water can be sprayed evenly, and then sown or transplanted with shallow soil. If the film is covered after application, the dosage should be reduced appropriately. (about 1/3 to 1/2), it has a significant effect on the prevention and treatment of 1 year old grasses and some broadleaf weeds.
Bio-pesticide experts are reminded that farmers should first master the basic knowledge of the pesticide and the specific steps of scientific and safe medication when using pesticides to prevent diseases.
