What medicine can Lolium multiflorum use for radical cure?

Lolium multiflorum has strong reproductive ability, fast growth rate and strong competitiveness in farmland, which will seize the nutrients and water resources of crops and have a negative impact on crop growth and development. What medicine can eradicate ryegrass? When is the best time to play?

1. What medicine can cure ryegrass?

Clomazone, metsulfuron, bensulfuron, fluconazole, isoproturon, etc. Lolium perenne can be radically cured, and the specific usage is as follows:

1, fenoxaprop-p-ethyl

Oxazolinofen is an effective herbicide, which can block the synthesis of amino acids in herbs, thus inhibiting the growth of plants. Oxazolidine has a good control effect on Lolium multiflorum, but it has little effect on other crops and plants. When in use, fenpropathrin is sprayed on plant leaves after the ryegrass germinates, and the dosage is 25-50g per mu.

2. Methyl disulfonate

Methyl disulfonate is a broad-spectrum herbicide, which can inhibit the activity of enzymes in herbs, thus inhibiting the growth of plants. Methyl disulfonate has a good control effect on Lolium multiflorum, but it also affects the growth of other crops and plants. When in use, methyl disulfonate can be sprayed on the soil surface before sowing crops, and the dosage is15-30g per mu.

3. Bensulfuron-methyl

Sulfoxide is a new herbicide, which can interfere with the growth and development of herbs, thus controlling the growth of Lolium multiflorum. Bensulfuron-methyl has less influence on other crops and plants and is safer to use. When in use, after the ryegrass germinates, it is sprayed on the leaves of plants, and the dosage is 20-30g per mu.

4. Flusulfuron-methyl

Flusulfuron-methyl is a broad-spectrum herbicide, which can be quickly absorbed by plant leaves and inhibit plant photosynthesis, thus achieving the effect of killing weeds. Flusulfuron-methyl has a good control effect on Lolium multiflorum, but it also does some harm to other crops and plants. When in use, after the ryegrass germinates, the sulfuron-methyl is sprayed on plant leaves, and the dosage is 20-40g per mu.

5. isoproturon

Isoproturon is a new broad-spectrum herbicide, which can inhibit the synthesis of auxin in herbs and thus control the growth and development of plants. Isoproturon has a good control effect on Lolium multiflorum and can also control other weeds. When in use, isoproturon can be sprayed on plant leaves before sowing crops or after ryegrass germination, and the dosage per mu is15-30g.

2. When is the best time to play ryegrass?

The spraying time of Lolium multiflorum should be before winter or in the young stage of weeds in winter and spring, preferably before the 4-leaf stage of grass. This period is the germination and growth period of Lolium multiflorum, and the control effect on herbaceous weeds is the best at this time. Before application, we should choose the appropriate medicament and application method according to the actual situation. Generally speaking, herbicides are the first choice to control Lolium multiflorum. Common herbicides are glyphosate, fluooxalic acid and glufosinate. Different herbicides can be selected according to different grassland environments and grass species. When using, you should follow the instructions and safe operation procedures of the drug to ensure the use effect and safety.

It should be noted that the weather should be prevented from being too cold or too hot when spraying drugs. Too cold or too hot weather will affect the absorption and function of herbicides and reduce the application effect. In addition, if there are many kinds of herbaceous weeds on the grassland at the same time, it is necessary to classify and apply pesticides according to different weed species and growth characteristics.

Conclusion: Bensulfuron-methyl, Bensulfuron-methyl, Bensulfuron-methyl and isoproturon can radically cure Lolium multiflorum, and it is best to apply them before winter or in the young stage of weeds in winter and spring, and it is best to apply them before the 4-leaf stage of grass.
