1. Wide herbicidal spectrum: Diquat is a biocidal herbicide, which has a good killing effect on most annual broad-leaved weeds and some grass weeds, especially for broad-leaved weeds.

2. Good quick-acting effect: Diquat can show obvious poisoning symptoms in green plants within 2-3 hours after spraying.

4. Short duration of effect: Diquat has only an upward conduction effect in plants due to its passivation in the soil, so it has poor control effect on the roots, and has a short duration of effect, generally only about 20 days, and weeds are prone to recurrence and rebound. .

5. Very easy to degrade: Diquat is more easily photolyzed than paraquat. Under strong sunlight, diquat applied to the stems and leaves of plants can be photolyzed by 80% within 4 days, and the diquat remaining in the plants after a week is very fast. few. Absorbs in soil and loses activity

6. Compound use: Diquat has poor effect on grass weeds. In the plots with more grass weeds, it can be used together with clethodim, Haloxyfop-P, etc., to achieve better weed control effect and control The grass period will reach about 30 days.
