Know what kind of herbicide is used in crushed rice

Broken rice is a kind of weed that is difficult to remove in rice field, so it is necessary to use herbicides, so what kind of herbicides should be used?

What kind of herbicide does broken rice know wind grass use?

Barnyardgrass can be removed by barnyardgrass herbicide plus cyanofluoxate. Both barnyardgrass herbicide and cyanofluoxate are selective herbicides, which can remove weeds in the field, but there is no danger to rice itself.

Introduction of herbicides

1. Paspalum herbicide

It is a highly selective contact herbicide of amides, which is mainly used in seedling or direct seeding fields. it is a specific drug for the control of barnyardgrass, and can also be used to control a variety of other grasses and dicotyledonous weeds, such as Hedyotis diffusa, water celery, Equisetum equisetifolia and so on.

It is best to apply in sunny days, but not more than 30 ℃. Don't drown the seedlings in the water layer.

Organophosphorus and carbamate pesticides should not be mixed with organophosphorus and carbamate pesticides, and organophosphorus and carbamate pesticides should not be used within two weeks before or after the application of paspalum to avoid drug damage.

2. Cyanofluoromethyl ester

Cyanofluoxate is the only herbicide of aroxyphenoxypropionic acid which is highly safe to rice. Like other varieties of this kind, it is also an internal absorption and conductive herbicide. Absorbed by the leaf and leaf sheath of the plant, conducted by the phloem, accumulated in the meristem area of the plant, resisted acetyl-CoA carboxylase (ACCase), stopped fatty acid synthesis, the cell growth and division could not be carried out normally, and the lipid-containing structures such as the membrane system were destroyed, resulting in plant death.

It is mainly used to control important Gramineae weeds. Cyanafluoroxalate is highly effective to Euphorbia paniculata, has a certain control effect on young paspalum grass, but also can control, Ma Tang, double ear paspalum, Setaria angustifolia, Rabdosia angustifolia and so on. It has no effect on Cyperaceae and broad-leaved weeds.
