Water flower rotten root herbicide

Water peanuts breed in large numbers in ponds, swamps, rice fields and other places, and farmers are very disgusted and want to kill them all. So what are the rotten root herbicides of water peanut?

1. Water blossom root herbicide

1. Using it to control water peanuts on the ridges, canals and ditches of paddy fields, the control effect is more than 95%. Use 20% per mu to make it emulsifiable concentrate 50m / mu 60ml and spray water 50m / mu evenly. It can be controlled by pesticide from germination to flourishing period. Do not spray the liquid on broad-leaved crops such as soybeans and peanuts to prevent drug damage.

2. The control effect of water peanut on the side of polder ridge road and river ditch is remarkable. In the peak period of the occurrence of water peanuts, with 10.5% water peanut withered 16 grams (1 pack), plus 10 kg of water spray, can control 200 square meters of water peanuts. After application, the water peanut turned yellow quickly, the stems and leaves withered and the roots were killed a week later. Generally used continuously for 2 years, the harm of water peanut can be eliminated.

3. The rotation of flood and drought can restrain the growth and spread of water peanut. Using water peanut special herbicide water peanut net (water agent) and water flower Shengguang (powder), spray water at the initial stage of water peanut occurrence, and when the local part is yellow wilt and then turn green, the water peanut can be killed by root again. Water peanut can be eradicated after continuous control for 2-3 years. In the places where the occurrence of water peanut is more serious, Nongda can be used to control it. Choose fine weather directional spray to prevent the liquid from drifting onto the crops and causing drug damage.

4. Nongda and gram can be used to control water peanuts. Using 41% Nongda 200MUR 300ml per mu, adding 20MUR 30kg of water, the liquid was evenly sprayed on weeds growing out of the water and roadside weeds. The medicine was absorbed by weed stems and leaves, and transmitted to rhizome tissue to play a herbicidal effect. In general, weeds such as water peanuts were killed by roots 10 days after the treatment. Nongda is non-toxic to fish and can control weeds growing on the water surface. Use 12.5% grams per mu without a trace 250 ml, add 25 kg of water spray. In sunny days, the green parts of weeds began to yellowing 3 hours after application, and 3 Mel withered within 4 days. Gram without trace can only kill the green parts of weeds, can not be transmitted in the plant, can not kill the underground stem, and the drug loses its activity after contact with the soil. Using gram without trace to control weeds on pool slope and polder ridge does not kill grass roots, which is beneficial to soil and water conservation.

5. During the growing period of water peanuts, the control effect is 85% 95% with 48% Baicao water agent 60ml, or 25% Huwei water agent 150ml, or 10% glyphosate water agent 2000 ml, or 20 g water-free agent 300ml, spray on water 40kg.

2. What are the hazards of water peanuts

1. It will affect the water traffic. Because they are aquatic plants, they block the waterway when they grow in the water.

2. Other plants are squeezed out on the water surface, resulting in the simplification of plants.

3. The growth rate is too fast, which affects the growth of the whole fish and the fishing work of fishermen.

4. it threatens farmland crops and leads to a decline in yield.

5. The growth of water peanuts will lead to mosquito breeding, and people living around them will be attacked by mosquitoes all the year round.

Generally speaking, the role and disadvantages of water peanuts exist, and we should deal with them dialectically.
