Pretilachlor - an effective broad-spectrum systemic herbicide
What is herbicide Pretilachlor?Pretilachlor (CAS 51218-49-6) is a selective herbicide commonly used in rice farming to control annual grasses and broadleaf weeds. It is primarily applied as a pre-emergent herbicide, which means it is used before the weeds start to grow. Pretilachlor works by inhibiting the seedling development of weeds, thus preventing them from competing with rice crops.
Pretilachlor(CAS 51218-49-6) is a synthetic chloroacetanilide herbicide used effectively in annual grasses and broad‐leaved weeds including Echinochloa Beauvois, Cyperus difformis, and sedges in rice and paddy fields.Pretilachlor is appears as a colorless and odorless liquid. It contains an ethoxylated vegetable oil as the emulsifying agent and alkyl aryl sulfonate of calcium salt as the surfactant.
pretilachlor is Chloroacetanilides are a group of anilide herbicides which commonly include alachlor, butachlor, metachlor, and pretilachlor. Pretilachlor is a broad‐spectrum systemic herbicide with the chemical name 2‐chloro‐2′, 6′‐diethyl‐N‐(2‐propoxyethyl) acetanilide.
What is the mode of action of Pretilachlor?
The mode of action of Pretilachlor involves inhibiting the synthesis of fatty acids in target plants. Pretilachlor is a member of the chloroacetamide herbicide group and primarily targets grassy weeds in rice crops. When Pretilachlor is applied to the soil or foliage of plants, it is taken up by the roots or absorbed through the leaves and then translocated within the plant. Once inside the plant, Pretilachlor inhibits the action of the enzyme acetyl-CoA carboxylase (ACCase), which is responsible for fatty acid synthesis. By inhibiting ACCase, Pretilachlor disrupts the production of essential fatty acids needed for the growth and development of the target plants. Without an adequate supply of fatty acids, the plants are unable to form important cell membranes and other lipid-containing structures, leading to growth inhibition and eventual death.
What is the herbicide pretilachlor used for?
pretilachlor is a pre-emergence, broad-spectrum herbicide of Chloroacetamide group which controls all type of weeds in rice.
Pretilachlor is a synthetic chloroacetanilide herbicide used effectively in annual grasses and broad‐leaved weeds including Echinochloa Beauvois, Cyperus difformis, and sedges in rice and paddy fields.
Pretilachlor Selective pre-emergent herbicide, inhibitor of cell division. Weeds absorb pesticides through hypocotyls and coleoptiles, interfere with protein synthesis, and have indirect effects on photosynthesis and respiration of weeds. Generally, soil treatment is used to control weeds such as barnyardgrass, duck leaf grass, heterosedge, mother grass, cow felt, Ci algae, firefly rush and other weeds in paddy fields, and the control effect on perennial weeds is poor. The dosage is 4.5-5.3g/100m2, such as rice seedling field or direct seeding field, use 30% emulsifiable oil 15-17mL/100m2, spray on water or sprinkle poisonous soil.

What class of herbicide is Pretilachlor?
Pretilachlor is a member of the chloroacetamide herbicide group and primarily targets grassy weeds in rice crops. When Pretilachlor is applied to the soil or foliage of plants, it is taken up by the roots or absorbed through the leaves and then translocated within the plant.
Pretilachlor is one of well known synthetic selective herbicide.
Pretilachlor was colourless liquid, and stock solution was prepared freshly in dimethylsulfoxide(DMSO) before use.
Pretilachlor is used to control annual grasses, broad-leaved weeds and sedges in rice and works by inhibiting cell division.
Pretilachlor and quinclorac were introduced for rice weed control at the same time, mainly to control barnyardgrass.
It is selective herbicide and it is taken up readily by the hypocotyls, mesocotyls and coleoptiles, and, to a lesser extent, by the roots of
Pretilachlor is effective against main annual grasses, broad-leaved weeds and sedges in transplanted and seeded rice, at 1-1.25 kg/ha.
Pretilachlor [2–chloro–2,6–diethyl–N–(2–propoxyethyl) acetanilide] is a chloroacetanilide herbicide which is widely used in rice cultivation for the control of several grasses, broad–leaved weeds and sedges.
Pretilachlor is used either as a pre–planting or post–emergence application.
In rice pre-planting and in pre-emergence of the weed the mixture of dimethenamid + pretilachlor in flooded soil gave the best results and prevented red rice germination by about 90%.
Pretilachlor shows a variable performance in relation to the soil characteristics and weather conditions but its efficacy against the weed does not commonly exceed, on average, 50% of the germinable seeds.
Features of Pretilachlor
It has a good weeding effect on a variety of weeds, especially on some herbaceous weeds that are difficult to get rid of.
It is easy to use and can be used for weed control by foliar spray or soil application.
The damage to crops is small, and weeding can be carried out without affecting the growth of crops.
What is the active ingredient in pretilachlor herbicide?
pretilachlor 30.7% w/w ec or pretilachlor 30% w/v ec is a safe, nonphytotoxic and selective pre-emergence herbicide with excellent action against annual grasses, weeds and sedges. it contains 307 g pretilachlor (2,6-diethyl-n-(2-propoxyethyl)-chloroacetanilide) per kg of emulsifiable concentrate (ec) formulation (w/w).
Is pretilachlor poisonous?
Pretilachlor poisoning in humans is an understudied area. It is widely used as a herbicide in India; hence it is of paramount importance that we understand the various clinical presentations from its toxicity. Acute oral intoxication of pretilachlor can present with neurological and gastrointestinal manifestations.
Pretilachlor is Selective herbicide. It is easily absorbed by the hypocotyl, mesocotyl and coleoptile, and to a lesser extent by the roots of germinating weeds.

Applications Pretilachlor
Pretilachlor (CAS 51218-49-6) is a chemical compound widely used in the chemical industry. It finds application in the production of pesticides, specifically herbicides. Pretilachlor functions as a selective pre-emergence herbicide, effectively controlling grass and broadleaf weeds. Its popularity stems from its high efficiency and low toxicity towards crops. Besides the pesticide industry, it may also have applications in other sectors such as agriculture and horticulture, where weed control is crucial for ensuring crop yield and quality.
Pretilachlor is a kind of selective herbicide. It is principally used for weeds of barnyardgrass, psrandletop, nutgrass, ducktongueweed in rice seeding bed and direct seeding. The period of validity shall be for 30-40 days. In rice direct seeding usually mix with soil or spray with water-mix.
