What herbicide works well on alligator weed

Alligator weed can be controlled with fluroxypyr, glyphosate aqueous solution, and bentazone liquid, and the application method differs depending on the size of the area.

1. What herbicide to use on alligator weed

The control methods for alligator weed are as follows, introduced here:

1. Use 40-70 ml of 20% fluroxypyr emulsifiable concentrate per mu, add 30 L of water, and spray evenly on the leaves.

2. Use 1000-2000 ml of 1% glyphosate aqueous solution per mu, add 20-30 L of water, and spray during the peak growth period of alligator weed; the control effect is very good.

3. Use 133-200 ml of 48% bentazone liquid per mu, add 30 L of water, and spray on the stems and leaves of the weeds; the control effect is fairly good.

2. What harm does alligator weed cause

1. It affects water traffic. Because it is an aquatic plant, it blocks navigation channels when growing in water.

2. It crowds out other plants on the water surface, causing plant monoculture.

3. It grows too fast, affecting the growth of the entire fish population and the fishing work of fishermen.

4. It threatens farmland crops, leading to reduced yields.

5. The growth of alligator weed leads to mosquito breeding, and people living nearby suffer from mosquito attacks year-round.

In general, alligator weed has both benefits and drawbacks, and everyone should treat it dialectically.
