Are diquat fast pesticide herbicides toxic?

Diquat fast. Pesticides and herbicides.

Of course, the toxicity is great.

Diquat fast, generally used as a conductive herbicide, can be quickly absorbed by green plant tissues, and quickly lose its activity after contact with soil. It is used for weeding in fields, orchards, non-arable land, before harvesting, etc., and can also be used as the stem and leaf drying of potatoes and sweet potatoes. In places where grasses are severe, and paraquat.

It works better when used together.

Diquat fast herbicide can be used to control soybean, sweet potato, cotton and other crops before harvest withering and defoliation.

How to use diquat fast:

1) No-tillage field weeding: used for weeding and no-tillage planting wheat and rape after rice harvesting, 2 to 3 days before planting, 80 to 130 ml of 20% water agent per mu, 25 to 30 kg of water, spray weed stems and leaves.

2) Withering and defoliation: 6 to 8 days before the harvest of rice and wheat, at the early stage of cereal waxing, that is, when the green grains only account for 4% to 5%, pesticides can be applied to promote drying. 100 to 150 ml of 20% water solution per mu, a conventional spray on water.

150 to 200 ml of soybean and 200 ml of potato and 200 to 250 ml of potato per mu.

Diquatat is a very powerful herbicide, and the toxicity of this pesticide is very high. Therefore, when using, it needs to be diluted according to the instructions for use and according to a certain dose.

The toxicity is still very large, because the herbicide is particularly good at weeding, the toxicity will be relatively large, and when spraying this pesticide, it is necessary to take protective measures.

The toxicity is particularly large, so you need to use less when using it, or you can mix it with water and then use it.

Diquat is generally used as a conductive contact herbicide, which can be quickly absorbed by green plant tissues and quickly lose its activity after contact with the soil. Where grasses are severe, it is better to use with paraquat.
