1 sweet potato field
Gather the sweet potato ditch and break up the soil clods. After the sweet potato seedlings are transplanted, take 130ml-150ml of 90% isopropylchlor EC per acre, mix it with 45-60kg of water, and spray it evenly throughout the field to effectively kill weeds.
2 soybean fields
Soil treatment before sowing seedlings, use 100-150 ml per mu in Northeast China; 67-100 ml per mu in other areas. Use the upper limit when the content of clay and soil organic matter is higher than 3%. Use 10-30 liters of water per mu and mix well for soil spray treatment .
3cornfield
Soil treatment before sowing seedlings, use 133 to 167 ml per mu in Northeast China; 100 to 133 ml per mu in other areas. Use the upper limit when the clay and soil organic matter content is higher than 3%. Use 10 to 30 liters of water per mu and mix well for soil spray treatment. .

The herbicide Propisochlor is a plant germination inhibitor, formulated as 72% Probao EC, and is suitable for controlling barnyardgrass, goosegrass, crabgrass, and other dryland crops such as soybeans, corn, sunflowers, potatoes, sugar beets, and peas. Annual grassy weeds such as foxtail grass and broadleaf weeds such as pigweed, amaranth retroflexus, amaranth, and nightshade. This agent has a good inhibitory effect on weeds such as volunteer sorghum, cocklebur, purslane, horsetail, etc., but is ineffective against weeds such as field bindweed.
The herbicide Propisochlor is used to control annual grass weeds and some broadleaf weeds. It is mainly used for crops such as corn and soybeans. It is a selective amide herbicide for pre-emergence and early post-emergence soil spray treatment. , can control annual grass weeds and certain broadleaf weeds in corn, soybeans, potatoes and other crop fields. It is easy to use, degrades quickly, and has no harmful effects on subsequent crops.
How to use Propisochlor (86763-47-5)
① Soybean field. Post-sowing and pre-emergence soil treatment. In Northeast China, 100 to 150 ml per mu (72 to 108 grams of active ingredient) is used; in other areas, 67 to 100 ml per mu (48 to 72 grams of active ingredient) is used. When the content of clay and soil organic matter is higher than 3%, the upper limit is used. Water is used per mu. Mix 10 to 30 liters evenly for soil spray treatment. If the weather is dry and the soil moisture is low, the soil can be lightly mixed to improve the weeding effect.
②Corn field. Post-sowing and pre-emergence soil treatment. In Northeast China, the dosage per mu is 133-167 ml (96-120 grams of active ingredient); in other areas, the dosage per mu is 100-133 ml (72-96 grams of active ingredient). When the content of clay and soil organic matter is higher than 3%, the upper limit is used. Water is used per mu. Mix 10 to 30 liters evenly for soil spray treatment. If the weather is dry and the soil moisture is low, the soil can be lightly mixed to improve the weeding effect.
The properties and differences of acetochlor, Propisochlor (86763-47-5), pretilachlor and butachlor
The herbicide Propisochlor is an amide herbicide, mostly for soil treatment. It has good control effect on annual grass weeds but poor control effect on broadleaf weeds.
Herbicide acetochlor: The duration of effect is about 45 days. It has little mobility in the soil and remains in the 0-3 cm soil layer. It is mainly degraded by microorganisms. It is easy to be exposed to high temperature and high humidity or continuous low temperature and high humidity within 1 to 3 days after sowing. It is suitable for peanuts, soybeans, corn, transplanted rapeseed, cotton, melons, and solanaceous vegetables that are prone to phytotoxicity.
The herbicide Propisochlor: the duration of effect is 30-35 days, and the activity disappears naturally 10-12 weeks after application. The control effect on grass weeds is better than that of broadleaf weeds. It is suitable for upland crops (soybeans, peanuts) , corn, cotton), vegetable crops (potatoes, cabbage, tomatoes, etc.), orchards and nurseries. Metochlor is the effective S-isomer of Propisochlor. It was launched in 1996 under the trade name Jinduer. Under the same dosage and conditions, its activity is 1.4 to 1.6 times that of Propisochlor. .
Herbicide pretilachlor: pre-emergent herbicide in rice fields, used to control annual grass weeds and broadleaf weeds in direct-seeded rice fields. After the rice seeds are germinated, spray the soil 2-4 days after sowing (after the rice takes root and establishes needles). There should be no accumulation of water in the field after use, and the soil should be kept moist for 3-5 days before normal water and fertilizer management!
Herbicide butachlor: a selective pre-emergence herbicide, mainly used to control annual grass weeds and certain broadleaf weeds in direct-seeded or transplanted rice fields. Butachlor is used for pre-emergence treatment of rice and can also be used after emergence!
Summary: Acetochlor, refined Propisochlor, and Propisochlor are used in dryland crops. The activity of refined Propisochlor is approximately equal to that of acetochlor. The activity of both is greater than that of Propisochlor, and the safety of refined Propisochlor is Alachlor and Propisochlor are greater than acetochlor! Pretilachlor and butachlor are suitable for pre-emergence soil treatment in rice fields!
Propisochlor (86763-47-5) Precautions
The herbicide Propisochlor's herbicidal effect can only be fully exerted when the soil is moist and moist. Therefore, the drug is suitable for application in film-covered fields, fields with irrigation conditions, summer crops and dry fields in the south. Isopropylamine can only kill germinating weeds, so it should be applied before weeds emerge.
First, the effect of the herbicide Propisochlor can only be exerted in moist soil, so the soil should be irrigated before use, and mulching film can also be used in fields.
Second, the herbicide Propisochlor can only kill germinating weeds, so applying the herbicide before weeds emerge will have no effect on weeds that have already emerged.
Third, spray isopropylchlor in closed environments such as plastic greenhouses and small sheds. Keep ventilation for 1-3 hours after spraying to prevent the formation of a film on the plastic film and cause phytotoxicity. There will be no harm when used in the field. Influence.
