What is the mode of action of butachlor herbicide?
What is butachlor herbicide?Butachlor is a member of the chloroacetanilide compounds. It is used as herbicide to control against grasses and broadleaf weeds in corn, soya beans, sorghum and peanuts grown in high organic content.Cas23184-66-9 It is applied to the soil as a pre- and post-emergence treatment. It is mainly absorbed by the roots and leaves, inhibiting protein synthesis in shoot meristems and root tips.
Butachlor is a herbicide of the acetanilide class.It is used as a selective pre-emergent herbicide.It is extensively used in India in the form of granules in rice as post emergence herbicide.Butachlor is an aromatic amide that is 2-choro-N-(2,6-diethylphenyl)acetamide in which the amide nitrogen has been replaced by a butoxymethyl group. It has a role as a herbicide, an environmental contaminant and a xenobiotic. It is an aromatic amide, an organochlorine compound and a tertiary carboxamide.

Butachlor Cas23184-66-9 is a herbicide used for pre-emergence control of annual grasses and some broad-leaved weeds. It has a low aqueous solubility and a low volatility. Depending on local conditions it may be moderately persistent in some soils. It is not expected to leach to groundwater. It is moderately toxic to most fauna and flora, the main exception being honeybees for which butachlor has a low toxicity. It has a moderate oral mammalian toxicity if ingested and is both a skin and eye irritant.
What is the herbicide butachlor used for?
Butachlor is an acetanilide weedicide that prevents broad-leaved weeds and grasses from germinating.It's most commonly utilized in rice and wheat fields.
Butachlor was developed for the preemergent control of grass and broadleaf weeds in rice and barley. Butachlor is available as emulsifiable concentrate and granular formulations sold under the trade.
Butachlor is a selective systemic herbicide effective against a wide range of both annual grass weeds and certain broadleaf weeds. It is applied prior to weed emergence, or in very early stage post-weed emergence in crops.
How to use butachlor herbicide
Butachlor is a pre-emergent chloroacetanalide herbicide. Butachlor is commonly used for weed control in rice as well as cotton, maize, wheat and other crops.
Pre-emergence selective anilide herbicide used to control grass and broad-leaved weeds in seeded and transplanted rice paddies.
1. For weeding in live vegetable fields such as kidney beans, cowpeas, cabbage, fennel, seedling cabbage, and spinach, use 100 ml per mu before sowing, mix with 40-50 kg of water, spray evenly on the border, and then sow.
2. Cauliflower, cabbage, eggplant, sweet (spicy) pepper, tomato, etc. are transplanted to the field. Before planting, use 150 grams per mu, add 50 kg of water, and spray the soil evenly.
3. Use in rice seedling field and direct seeding field: After the field is ready, 2-3 days before sowing, irrigate the shallow water layer, use 75-100 .
Butachlor Agricultural Uses Herbicide
Butachlor a pre-emergence herbicide for control of annual grasses and broadleaf weeds. It is used on cabbage, citrus cops, coffee, all types of corn, cotton, green peas, maize, onion, peanuts, potatoes, vineyards, sugar cane, and sugar beets, among others. It is compatible with most other pesticides.
Metabolic pathway The initial metabolism of butachlor is investigated to delineate the detoxification pathway using tolerant corn and soybean seedlings. Butachlor is rapidly absorbed and metabolized by etiolated corn seedlings to the glutathione conjugate and is also rapidly metabolized by etiolated soybean seedlings. However, the initial metabolite by soybean seedlings is the homoglutathione conjugate, not the glutathione conjugate.

Features of Butachlor
Butachlor is a selective, systemic, pre-emergent soil treatment agent. There are mainly weed shoots (the absorption part of Gramineae is the coleoptile, and the absorption part of broad-leaved grass is the hypocotyl), young secondary roots, and seeds can also absorb, but the amount of absorption is very small. After the medicament is absorbed by the weed, it conducts in the weed body, inhibits the synthesis of protein, makes the young weed plant swollen, deformed, dark green in color, and eventually leads to death. Only a small amount of Butachlore can be absorbed by the rice seedlings, and it is rapidly and completely degraded and metabolized in the body, so the rice seedlings have greater drug resistance.

It is mainly used for the control of annual gramineous weeds, annual sedge weeds, and some annual broad-leaved weeds in paddy fields, and can also be used for weed control in barley, wheat, cotton, and peanut crop fields. For example, use 10-30g active ingredient/100m2 to control weeds such as barnyardgrass, water onion, firefly, cattle felt, knotgrass, and bermudagrass in rice fields. 6.8g/100m2 of 60% EC was used 2-3 days before sowing in rice seedling field. After winter wheat and barley are sown and covered with soil, combined with irrigation of seedling water or rainfall, when the soil moisture is good, use 15-18.8mL/100m2 of 60% EC to evenly spray the water on the soil surface.
Butachlor It is a high-efficiency and low-toxic pre-emergent herbicide, mainly used for the control of most annual grasses and some dicotyledonous weeds in dryland crops. It isused for the control of weeds such as barnyardgrass, goosegrass, and bermudagrass in rice. It is a selective pre-emergent herbicide for controlling gramineous weedsand annual broad-leaved weeds in paddy fields.
Butachlor It is mainly used for the control of annual grass weeds and certain broad-leaved weeds in direct seeding or transplanting paddy fields. Also selective for wheat, barley, sugar beet, cotton, peanut and cabbage crops. The effective dosage is 1.0-4.5kg (active ingredient) per hectare. It is generally used for soil surface treatment before emergence, and it can also be applied after emergence in paddy fields. It is an important variety of herbicides in paddy fields.

Butachlor can cause severe toxicity
Acute toxicity
Butachlor causes slight erythema and edema in rabbits when exposed to 24 h continuously.It can also cause dermal sensation, moderate-to-severe erythema with edema in guinea pig.
Human and Animal toxicity
Butachlor can cause DNA strand breaks and chromosomal aberrations in mammalian cells exhibited.Butachlor can also trigger necrosis in human PBMN cells due to their oxidative role in intracellular reactive oxygen species[ROS] production, and the consequent mitochondrial dysfunction, oxidative DNA damage and chromosomal breakage. Butachlor has mutagenic effects in primary rat tracheal epithelial cells and in Chinese hamster ovarian cells.It is also known cause stomach tumors in rats.
