Paraquat is a non-selective herbicide. However, due to the lack of a specific antidote, the mortality rate after poisoning is high, the death process is long, and patients suffer greatly. There is a strong call for its ban in society. In order to safeguard people's lives and health safety and ensure the safe production and use of paraquat, the Ministry of Agriculture has successively taken relevant measures in recent years to strengthen the agricultural registration, production, sales and use management of paraquat products. Paraquat, with the chemical name 1-1-dimethyl-4-4-bipyridine cationic salt, is a fast-acting non-selective herbicide. It has contact killing effect and certain systemic effect, and can be quickly absorbed by the green tissues of plants, causing them to wither and die. It has no effect on non-green organizations.

Mode of action Non-selective systemic herbicide, absorbed by the foliage, with rapid translocation throughout the plant. Inactivated on contact with soil.
Uses Control of annual and perennial grasses and broad-leaved weeds, pre-harvest, post-planting/pre-emergence and in stubble, in cereals, peas, beans, oilseed rape, flax and mustard, at c. 1.5-2 kg/ha; as a directed spray in vines and olives, at c. 4.3 kg/ha; in orchards, pasture, forestry and industrial weed control, at c. 4.3 kg/ha. As an aquatic herbicide, at c. 2 kg/ha.
Formulation types SG; SL.
Compatibility Mixing with other herbicides may reduce the activity of glyphosate.
Selected tradenames: 'Rodeo' (isopropylammonium salt) (Monsanto); 'Roundup' (isopropylammonium salt) (Monsanto); 'Sting' (isopropylammonium salt) (Monsanto) etc
It is a non-homogeneous triazine herbicide and a photosynthesis inhibitor. It is mainly used to control gramineous weeds (especially broomweed) and certain broadleaf weeds in cereal crops (such as wheat) and tomato fields, with a dosage of 0.55 to 1 kg of active ingredient per hectare. When applied before germination and after germination in autumn, it has an excellent control effect on the tail of the rat. Applied before tillering, it can control wild oats, chickweed, etc. The dosage is 0.75 to 1.5kg/hm2.

Uses:
For seed treatment, fluxofenim is a herbicide antidote that protects grain or forage sorghum from injury due to herbicide like s-metolachlor. It also helps provide better weed control and greater care for the crop and the environment.
Uses:
Cyprosulfamide is a safener for herbicides like Isoxaflutole, Thiencarbazone-methyl, Nicosulfuron and Dicamba on corn or maize. It works within the plant systemically, through both soil and foliar uptake, to increase the rate of metabolic activity, thus contributes to corn safety while the herbicide works to the weeds. It also increases the flexibility of application timing, compatibility over various soil types and maximizes root growth and plant health.
Mode of action:
Selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation in xylem and phloem to the meristematic tissues.
Uses:
Selective post-emergence control in maize of annual grass weeds, broad-leaved weeds.
Mode of action:
Selective systemic herbicide. Activity comes from the formulation of the herbicidally active monocarboxylic in the initial metabolic step in the susceptible grasses after leaves absorption.
Uses:
Control of annual and perennial grass weeds in rice field with only post-emergence activity. It is highly effective against barnyard grass, leptochloa and some other paddy weeds. In some situation, cyhalofop-butyl can be used to deal with propanil or quinclorac-resistant echinochloa. It is suggested that 2.3 l/ha of crop oil concentrate be added to the tank with the herbicide. To maximize the efficacy, better be applied within 2 weeks following flood establishment in rice fields.
Mode of action:
Selective systemic herbicide that inhibit the enzyme acetolactate synthase (ALS), absorbed by foliage and roots.
Uses:
Control of annual and perennial grasses, broadleaf weeds and sedges. It has a wide window of application and can be used from the 1-7 leaf stages of Echinochloa spp; the recommended timing being the 3-4 leaf stage. The product is for foliar application, most used crops are rice and turf. For growth regulator use, bispyribac-sodium should be applied before weeds are 10 cm tall in rice fields and before weeds are 30 cm tall in non-agricultural areas. The use of PASS is recommended for optimum activity.
Mode of action:
As a systemic sulfonylureas herbicide, and a ALS inhibitor.
Uses:
Used as a post-emergence herbicide, it has good control for annual grass weeds and some broadleaf weed like chickweed in winter and spring wheat.
Selective systemic herbicide, absorbed by the roots and the foliage, with translocationacropetally in the xylem and accumulation in the apical meristems and leaves. Pre- andpost-emergence control of annual broad-leaved weeds and annual grasses in maize,sorghum, sugarcane, pineapples, chemical fallow, grassland, macadamia nuts, conifers,and industrial weed control. In Europe, use is concentrated in maize and sorghum. Usedalso in combinations with many other herbicides.
