What do you know about the use of acetochlor?

Be sure to choose the appropriate concentration according to the variety of crops, according to the growth of crops, dilute with water in advance, and never use it when the temperature is relatively high and the rain is relatively heavy.

AcetochlorThe scope of use of herbicides is: acetochlor is a low-toxicity herbicide, which is safe for humans, animals and crops, and has a long validity period (60 70) days for weed control, and a single application can control the entire growth period without weed damage. Acetochlor is a selective herbicide that is absorbed mainly through the young shoots and young roots of weeds, and monocotyledon grasses are absorbed through bud sheaths.

When the agent enters the weed, it inhibits the growth of young shoots and roots, and finally wilts and dies. Acetochlor can be used in soybean, potato, cruciferous, leguminous and other crops, mainly to control horseshoe, barnyard grass and dogtail grass.

purslane, etc., but not effective against perennial weeds.

Acetochlor is a selective pre-budding herbicide, mainly for the control of horsegrass, barnyard grass, dogtail grass, purslane, etc., ineffective for perennial weeds, suitable for soybean, peanut, corn, rape, sugarcane, cotton, potato, cabbage, radish.

Kale, cauliflower.

Tomatoes, peppers, eggplants, celery, carrots, lettuce, chrysanthemum, leguminous vegetables, citrus, grapes, orchards and other dryland crops are controlled before budding annual grasses and some dicotyledon weeds, soybean cuscuta.

First aid measures. **Contact: Immediately take off contaminated clothing, rinse contaminated **, hair, nails, etc. thoroughly with soapy water and running water.

Eye contact: Rinse with running water or saline.

Respiratory tract. Inhalation: Quickly remove the patient from the scene to fresh air to keep the airway open. Such as difficulty breathing.

Give oxygen inhalation, etc.**. If breathing stops, artificial respiration is performed immediately.

Gastrointestinal intake: induce vomiting after drinking warm water to the person who has taken it by mistake, or repeatedly wash the stomach with normal saline.

Rice, wheat, millet, sorghum, cucumber, spinach and other crops are sensitive to acetochlor and should not be applied.

The control targets of acetochlor are annual grasses and broad-leaved weeds with small seeds. There are special effects on annual grasses such as horsetail, dogtail grass, cow tendon grass, barnyard grass, goldenrod, kanmai niang, wild oats, early maturing grass, hard grass, teff grass and other annual grasses.

It also has a certain control effect on broad-leaved weeds such as Chenopodaceae, Amaranthaceae, Polygonaceae, Duck Plantar Grass, Chickweed, and Silkseed, but the effect is worse than that of Poaceae weeds, and it is ineffective against perennial weeds.

Applicable crops such as corn, cotton, beans, peanuts, potatoes, rape, garlic, tobacco, sunflower, castor, green onions, etc. Precautions (1) Use a low dose for sandy soils and a high dose for clay soils. (2) For soils with organic matter content of more than 4% in Northeast China, the dosage should be increased by about 30%.

3) When the soil moisture content is low, use a high dose, and when the soil moisture content is high, use a low dose. (4) Due to the dry weather in spring in northern China, when applying acetochlor in a large area in the spring in the north, it is best to apply the pesticide before sowing or transplanting, so as to facilitate the mechanized mixing operation. (5) Wheat, rice, millet, sorghum, cucumber, watermelon, melon, spinach, and leeks are sensitive to acetochlor and should be used with caution.

6) This product is only effective for weeds before germination and unearthing, and can only be used as a soil treatment agent. (7) Soil temperature affects the speed of plant absorption of this product, and the absorption rate is higher at higher temperature (27 32) than at lower temperature (16 21), so the amount of crops sown in higher temperature areas or summer sowing fields in the south is lower. (8) Among the factors such as sowing depth, thickness of the pesticide layer, soil properties, climatic conditions and plant absorption parts, it was mainly affected by the sowing depth and the depth of soil covering after the pesticide.

In general, crop seeds should be sown under the pesticide layer and ensure that the soil is well covered. (9) The activity of this product is affected by soil type, moisture, organic matter content and soil temperature. The dosage is generally 1 times higher in areas with low soil temperature, high organic matter content, low rainfall and clay-like soils.

The amount of pesticides used in sandy soil should be reduced accordingly to prevent heavy rainfall from bringing a part of the pesticides that are not completely adsorbed by soil particles to the root layer and contact the young shoots and roots, which may cause pesticide damage. (10) The application method is the same as other pre-bud herbicides, and the sprayer is applied after sowing or transplanting, generally not more than 3 days, or before sowing or transplanting at the end of land preparation. For plots that need to be drained, ditch in advance and spread the ditch mud before spraying.

Before application, the soil surface should be fully leveled, and there are large pieces of soil that hinder the weeding effect. (11) In order to ensure uniform spraying, it is recommended to use fan-shaped or other narrow nozzles. If mechanized farming is used in the northern region, water can be added to the medicine box of the motorized sprayer, and then the rated amount of medicine can be added, and it can be sprayed by stirring evenly.

12) The activity of this product is very high, and the dose should not be increased at will during application, and it should be sprayed evenly to avoid re-spraying and missing spraying. The lower limit of the amount of land withdrawal of plastic film cover crops. If there is no 5 lomm rainfall within 15 days after application, artificial irrigation is recommended to promote the germination of seeds and the spread of pesticides to form a control layer to ensure the effectiveness of seedlings and weed control.

Pay attention to drainage after rain in rainy areas, and water accumulation after heavy rain in poorly drained plots will hinder crop emergence or slight pesticide damage. (13) In case of low temperature on rainy days after pesticide application, crops may show leaf greening, slow growth or shriveling, but with the increase of temperature, it will resume growth, which generally does not affect the yield. (14) Rice, wheat, millet, sorghum, cucumber, spinach and other crops are sensitive to this product and should not be applied.

15) Empty containers and spraying utensils should be cleaned with clean water many times, and this sewage should not be allowed to flow into water sources or ponds.

Summary. Acetochlor is a selective pre-emergence herbicide, suitable for soybean, peanut, corn, rape, sugarcane, cotton, potato, cabbage, radish, cabbage, cauliflower, tomato, pepper, eggplant, celery, carrot, lettuce, chrysanthemum, leguminous vegetables, citrus, grapes, orchards and other dryland crops before the bud control of annual grasses and some dicotyledon weeds, soybean dodder seeds. The preparations include 90% Honine EC, 50% acetochlor EC, 88% acetochlor EC and 20% acetochlor wettable powder.

The correct way to use acetochlor.

Good afternoon, I have checked your questions, and I am inquiring for you, please wait a while, don't end the consultation immediately! <>

Good afternoon, I'm happy to answer for you, acetochlor needs to wait until corn, cotton, soybeans, peanuts and other crops are ready to use again, combined with seedlings to leave seedlings shallow hoe again, usually an acre of dosage of 150ml, need to mix 90 pounds of water, in the use of pay attention to strict follow the instructions, can not increase the dosage at will, at the same time before and after spraying, to keep the soil in a moist state, to ensure the efficacy. ”

Inochlor is inoculated, and does it still work if it rains five days later?

Dear please wait, we are inquiring,,, we will answer you immediately.

Good afternoon, happy to answer for you, generally speaking, 6 hours after the herbicide and then rain, will not affect its efficacy. It certainly doesn't matter if it rains after five days.

If it rains, it will dilute the effect of the medicine on the ground, right?

It took six hours for it to rain to have an impact.

Acetochlor is a widely used herbicide. It is one of the most important herbicide varieties in the world and one of the most used herbicides in our country. During the growth of crops, weeds are very common, if the weeds in the field are not treated in time, it will seriously affect the normal growth of crops, therefore, many people will choose to use acetochlor to weed the farmland, and the use time of acetochlor will often have many problems that affect the efficacy.

So, what are the factors that affect the efficacy of acetochlor and what is the correct way to use it?

On soybean, rapeseed, peanut, potato, wheat and other crops, spraying 1-2% acetochlor EC before flowering can increase the flowering period and improve the flowering rate; On a variety of crops such as rice, wheat, rapeseed, etc., spraying 2-5% acetochlor EC before potato setting can improve the potato setting rate and increase the yield. On various crops such as rice, wheat, rapeseed, etc., the product can be used for control before sowing or before sowing seedlings.

It can be used before flowering and before tubing, which can improve the flowering rate and increase the yield; When mixed with some pesticides, the weeding effect is also good, when mixed, the seeds should be fully dried first, and then mixed with pesticides, herbicides and pesticides should be mixed first, and they need to be used in sunny days or high temperature conditions after mixing. Because the biological activity of acetochlor is higher than other herbicides, it can quickly enter the crop body after application, and when using herbicides, acetochlor must be sprayed on the root neck of the crop to inactivate it, and then proceed to the next step.

After acetochlor is applied, the active ingredient is quickly absorbed by the plant, and the upper limit of the herbicidal spectrum can be reached within 5 seconds, and the acetochlor in the solution can be quickly absorbed by the plant and spread rapidly in the crop, and the action time of acetochlor is 3-6 days. Crops with acetochlor can effectively control the growth of weeds, while for some difficult-to-control weeds, the effect of weed control and weeding can be achieved by increasing the number and time of pesticide application. Acetochlor has a contact killing effect, and has a strong contact killing and stomach toxicity effect on most bacteria, fungi, viruses and various insects, so in the prevention and control of some special crops, acetochlor can be considered to replace fungicides.

During the growth and development period of grain crops, weeds are scattered, which will not only endanger the growth and development of grain crops, but also cause the reduction of resource consumption, grain crop quality and production. Therefore, the application of acetochlor and other organic chemical products to control weeds has become one of the key tasks of farmers. As everyone knows, when applying acetochlor, various problems often occur in its use effect.

What are the aspects that will harm the herbicidal effect of acetochlor? How to use acetochlor? I'll lead you to find out below:

1. The temperature is slightly lower.

In early spring, ultra-low temperatures or slightly lower soil temperatures, the use of acetochlor usually jeopardizes the full use of the efficacy, resulting in the adverse effects of poor weeding effect. Not only acetochlor, but also many herbicides are also affected by ultra-low temperature at different levels.

2. Climatic drought.

The herbicidal effect of acetochlor is very harmful to soil moisture. After spraying, if there is little rain and drought, the effect is usually not very good. When in use. The water flow can be moderately increased to improve the efficacy.

3. The relative density of weeds is too large.

All a herbicide. It is also difficult to achieve a 100% prevention effect in the whole process of large-scale use, and the same is true for acetochlor. Even if the control effect is 1j90, if the relative density of weeds in the field is too large, the remaining 10 weeds will still cause some damage to the crops.

4. Weeds are more complicated.

Acetochlor has a good control effect on many weeds, but it is not good for any weed control base, so when there are more types of weeds in the field, there will still be some weeds that are not sensitive to acetochlor.

5. The quality of spraying is not very good.

The quality of the spraying immediately jeopardizes the efficacy of the drug. If the spraying is uneven, it will inevitably lead to a part of the road surface leakage, and the prevention effect is difficult to ensure.

6. Dosage is prohibited.

To control weeds, it is necessary to accurately control the amount of drugs used. If the dose is insufficient, the prevention effect cannot be achieved; On the contrary, if you use too much, it will not only consume chemical fertilizer, increase costs, but also easily cause fertilizer damage.

7. Ploughing is not careful.

The use of herbicides is more stringent on tillage. If the ploughing is not careful, there are more soil stubbles, or the crop stubble of the previous year is not cleaned, etc., it will definitely endanger the uniformity of the road surface medicine, resulting in some weeds not touching acetochlor after the unearthed cultural relics, and the control effect is not very good.

8. Spray when the wind is strong and the temperature is high.

In case of wind and high temperature, the spray is easy to be blown away by the wind, so that the road surface is leaked or the dose is insufficient, and the prevention effect cannot be achieved.

9. Deficiencies of the drug itself.

The quality of a drug is a key factor in harming its efficacy. Some fertilizers are stored for too long, resulting in reduced or ineffective efficacy; Some chemical fertilizers have insufficient chlorogenic acid components, and they cannot achieve the estimated control effect. The existence of counterfeit and shoddy goods should be given due attention.

The reason why acetochlor is not effective may be because the temperature of the soil is particularly low, or when Huihu is used in the spring before the beginning of the air difference, or because it encounters a rainy day after use, or because the dilution is too serious and the effect is not obvious.

I know that it may be because the temperature is too low, or it may be because there has been a drought, or because the weeds are more abundant, and the bridge has affected the whole field, so there is such a problem.
