Is the spraying of pesticides 24 butyl ester and acetochlor on rice in seedbed soil?

Acetochlor is a selective pre-bud treatment herbicide, which is mainly absorbed by the coleoplasty of monocots or the hypocotyl of dicots, and conducts upward after absorption, mainly by hindering protein synthesis and inhibiting cell growth, so that the growth of weed shoots and young roots is stopped, and then die. The ability of grasses to absorb acetochlor is stronger than that of broad-leaved weeds, so the control effect of grasses is better than that of broad-leaved weeds. The effective period of acetochlor in the soil is about 45 days, and it is suitable for crops

Corn, cotton, beans, peanuts, potatoes, rape, garlic, tobacco, sunflowers, castor. Wheat, rice, millet, sorghum, cucumber, watermelon, melon, spinach, and leeks are sensitive to acetochlor and should be used with caution.

Therefore, acetochlor cannot be used for closed weeding of rice seedbeds.

The pesticide 24-butyl ester (2,4-butyl ester) sprayed on the seedbed soil has no pesticide damage to rice.

Acetochlor is harmful to rice.

How to use 2,4-butyl ester (2,4-d butyl ester).

It is used in winter wheat and barley fields.

The applicable period is the end of tillering, the 3rd to 5th leaf stage of broad-leaved grass, 50 to 100 ml of 72% 2,4-butyl ester emulsifiable concentrate per mu, and 30 to 40 kg of water dilution spray.

Spring wheat, barley barley fields use.

The applicable period is from 4 to 5 leaves of the crop to the peak tillering stage, and the dosage is the same as that of winter wheat.

It is used in corn and sorghum fields.

3 to 5 days after sowing, 50 to 100 ml of 72% 2,4-drop butyl ester emulsifiable concentrate per mu before emergence, and about 35 kg of water should be evenly sprayed on the soil surface and unearthed weeds. It can also be used in the 4-5 leaf stage after the emergence of corn and sorghum, with 40 to 65 ml of 72% 2,4-drop butyl ester emulsifiable concentrate per mu, about 35 kg of water, and spray weed stems and leaves.

Millet field use Applicable period: 4 to 6 leaf stages of grain seedlings, 30 to 50 ml of 72% 2,4-drop butyl ester emulsifiable concentrate per mu, 15 to 20 kg of water, and spray weed stems and leaves.

Rice field use. The applicable period is the end of rice tillering, with 35 to 50 ml of 72% 2,4-butyl ester emulsifiable concentrate per mu and 30 kg of water spray. Drain the water layer the night before spraying, water the next day after application, and manage normally after that.

Sugarcane fields are used.

The applicable period is before the germination of sugarcane, with 150 to 200 ml of 72% 2,4-drop butyl ester emulsifiable concentrate per mu and 30 kg of water spray.

Pasture use. 150 to 200 ml of 72% 2,4-drops butyl ester EC per mu and 25 to 50 kg of water spray.

Precautions. 2,4-butyl ester is very sensitive to dicot crops such as cotton, soybean, rapeseed, sunflower, and melon. When spraying, it must be carried out in windless or breezy weather, and should not be sprayed or drifted into sensitive crops to avoid pesticide damage, and 2,4-drops of butyl ester cannot be used in fields with sensitive crops.

Strictly control the application period and dosage, wheat and rice are sensitive to 2,4-drop butyl ester before the 4-leaf stage and after jointing, so they should not be used.

Sprayers are better to be specialized. In order to avoid pesticide damage caused by spraying other pesticides. If it cannot be used exclusively, spraying 2,4-drop butyl ester is sensitive and should not be used.

2,4-D butyl ester cannot be in contact with acid and alkali to avoid decomposition and failure.

Summary. Hello dear, 1It can be used, but it must be taken care not to overdose.

2.Take the medication according to the dosage specified in the instruction manual. Spraying should be even, no spraying and no repeated spraying.

If butachlor granules are sprinkled, attention should also be paid to evenly spreading. Generally, the effective content of butachlor per hectare of paddy field can not exceed 1275 grams, more than this dose may produce different degrees of pesticide damage, the effective content of 2000 grams per hectare of rice will appear obvious pesticide damage symptoms, do you think there is anything else that needs help?

Can you use butachlor after rice seedlings.

Hello, I've seen your question, I'm sorting out the answer, please wait a while Hello, I've seen your question, I'm now hand-hungry for you, but it takes a little time, please wait patiently, thank you

Generally, the effective content of potato acactuate can not exceed 1275 grams per hectare of paddy field, and more than this dose may produce different degrees of pesticide damage, and the lead content of 2000 grams per hectare of rice will have obvious pesticide damage symptoms.

Summary. 24-d is generally used as a herbicide for the control of broad-leaved weeds of cereal crops, and has a small effect on cereals, but in view of the fact that it is a seedbed, it is recommended not to use it, referring to the following reasons, this agent is generally used in corn field production.

24-d is generally used as a herbicide to control broad-leaved weeds in front-facing crops with cereals, and has little effect on cereals, but in view of the fact that it is a seedbed, it is recommended not to use it.

This paper analyzes the reasons for the prominence of pesticide damage in the seedbed of large and medium shed dry seedlings of rice, and puts forward some matters that should be paid attention to in order to avoid herbicide damage, that is, do not take topsoil seedlings in plots with long-term residual herbicides such as imidazole ethnicotinic acid, chlorsulfuron-methyl, xapyrus or atrazine. Do not apply acetochlor (or agents containing acetochlor), and in some cases do not apply cryptochlor. flutter or butachlor for seedbed closure weeding; Do not apply dimethyltetrachloride and butyl ester at the seedling stage, or apply dichloroquinolic acid too early and excessively; The use of stem and leaf sprays such as goldenrod, dibarium or pine should be promoted to control weeds in the seedbed.

Thank you. You're welcome <>

Summary. Hello dear, since the residual toxicity of acetochlor is too strong, the remedy for rice seedbeds is to use organic plant resistants to reduce the effects of residual toxicity in order to restore the growth activity of the seedbed. First of all, the biological dispersion method should be adopted, that is, spraying a certain amount of organic resistants, such as amino acids, phosphate nitrile and oleochemicals, can help the anions in the seedbed substance, such as acetochlor, which are easy to be killed by a small amount of cations, thereby reducing the molecular toxicity of the soil, thereby alleviating the toxicity of acetochlor.

In addition, the impact of residual toxicity on the seedbed can be mitigated by changing the sowing or seedbed management method, such as increasing the seeding density and adjusting the fertilization level, to increase the growth quality of the seedbed.

Does mulch film cover need to be removed.

Tomorrow there will be rain and the pesticide seller will say that the rain will be more serious.

Dear, the rain will not be more serious, and the pesticides will be diluted by the rain.

There are three days of rain, so do you have to take the antidote after the mulch is removed?

What is the full name of the antidote, and what medicine do I go to buy?

Dear, you don't need to use the antidote, peel off the film and let the rain dilute the pesticides.

If you don't use medicine, won't that affect its germination and growth?

Dear, I'm talking about not using acetochlor, other non-toxic pesticides can be used.

It should be that the use of butachlor is indeed a mistake to hit ethoxam, what is the antidote to ethoxam?

Pro, organic plant resistance agents can be used to reduce the effects of residual toxicity.

Summary. Pro-in-growth regulator is sprayed after the damage of butazonite.

The damage of butafen puff can be alleviated by foliar fertilizer.

Depending on the situation, re-seedlings should be re-raised as soon as possible so as not to affect the yield in the end.

Foliar fertilizer can be sprayed with light pesticide damage to alleviate and serious re-seedling.

Foliar sprays of plant growth regulators are sufficient.
