Does paraquat die when you put paraquat in water when watering a cornfield?

Paraquat is one of the most potent herbicides, so don't spray it on corn when spraying, as corn or other crops won't survive if they are wet. In the booting stage of corn, that is, after the corn appears "big flare", the female spikelets and florets of corn begin to differentiate, and timely re-application of bract fertilizer can promote the normal development of ears and increase grains, generally 14 days before heading. If the base fertilizer is insufficient and the growth of corn is weak, it is necessary to increase the amount of fertilizer, and the rotting farmhouse fertilizer and Yanwo microbial agent can be applied per mu, and at the same time, according to the soil moisture, appropriate watering to replenish the water.

Proper fertilization at the flowering stage can prolong the grain filling period of corn, promote grain filling, improve seed setting rate, and increase yield. If in the early management, the fertilization is insufficient and the soil nutrients are insufficient, it is best to apply an appropriate amount of tapping fertilizer. It can be used per mu with water-soluble fertilizer and high phosphorus fertilizer, mixed with an appropriate amount of fine soil, and applied near the roots of the plant, but do not directly contact with the root system.

If the soil moisture is insufficient, it can be used to irrigate the roots of the plants with fertilizer and water.

This depends on the concentration, generally speaking, the concentration of round-leaved grass can die if it is slightly lower, and the high concentration of pesticide corn may also be killed.

It is recommended to strictly configure the concentration according to the instructions for use.

In addition, isn't it useful to spray weeds on the leaves of general pesticides? If the water is in the form of drip irrigation, it may affect the use effect.

I think when I put paraquat in the water when I water the corn, the corn will die.

Paraquat can only be targeted at weeds, and if it gets on corn, the chances of survival are slim.

From the tasseling stage to the flowering stage, the plants basically stop growing, and the consumption of nitrogen accounts for about one-fifth of the whole growth period, phosphorus accounts for about one-fifth, and potassium accounts for about one-third. Once the filling begins, the amount of fertilizer required for the corn increases rapidly, forming proteins, starches, and fats in the grain until the grain is ripe. This period absorbs about half of the nitrogen and about one-third of the phosphorus during the entire growth period.

In addition, "shelling" is best to apply controlled-release fertilizer, and the ratio of nitrogen, phosphorus and potassium (28-5-9) is close to optimal, the number of acres of fertilizer is 80 catties, and fertilizer can be planted or 3 leaf stage joint time one-time application. It should be noted that in order to prevent the seedlings from burning during fertilization, holes or strips should be made at a depth of 6-8 cm from the plant at a depth of 7-10 cm. Most of the areas with general fertilizer retention can be divided into two and three applications.

In principle, phosphorus and potassium fertilizers are applied fully, and nitrogen fertilizers are generally not higher than 20% to 30% of the total nitrogen rate.

Can't get out. This is because paraquat is a rapidly occurring herbicide with contact killing and systemic effects. It can be quickly harvested by the strength of the green tissue of the plant, so that it dies quickly.

Of course, you can, but it's best to do it after a while, because acetochlor is a fiefdom, and it's best not to enter it for a short time after the fight, as it will lose its effect after stepping on it, so it's best to do paraquat again after a few days.

After corn is planted, paraquat can be used to control weeds before emergence.

Paraquat can be used alone or in combination with occlusives. The sown corn has emerged seedlings, can not be sprayed in the whole field, the choice of windless days can be a single ridge directional spraying grass, absolutely can not be sprayed on the corn, if sprayed will have an impact.

Paraquat is a very powerful herbicide, and if it hits corn, it will not survive, so it is better to replant the seedlings as soon as possible. Corn-based fertilizer is the base fertilizer, which should be reapplied, mainly organic fertilizer, plus some nitrogen, phosphorus and potassium compound fertilizer, and then add it appropriately if there is a lack of zinc.

The base fertilizer is mainly farmhouse fertilizer, which is mainly made of livestock and poultry manure through fermentation and decay, which is rich in microorganisms, has the characteristics of long fertilizer efficiency and sufficient nutrients, and has an obvious effect on the improvement of soil physical and chemical properties. In the application according to the soil fertility situation, generally apply about 2 tons of organic fertilizer per mu, and with 10 kg of ammonium fertilizer, 20 kg of phosphate fertilizer, and 6 kg of potassium fertilizer.

If there is a shortage of zinc fertilizer in the plot, it should also be appropriately increased with ribery Yanwo zinc fertilizer. The basal fertilizer is generally applied in combination with the ground before sowing, which can be applied in holes or strips, and after application, the fertilizer is covered with about 4 cm thick fine soil to avoid direct contact between the seeds and the fertilizer to burn.

Seedling fertilizer is generally applied when the plant grows to 3-4 leaves after emergence. With the rapid growth of plants, the amount of fertilizer required is increasing, and the seedling fertilizer should follow the principle of early application and light application.

Corn accidentally injured paraquat. If there is, there is no cure for paraquat, and there is no antidote to paraquat. Don't say that the fight is a human being. There is no antidote for drinking it by mistake. So, this medicine is banned in the country.

If a small amount of paraquat is accidentally sprayed on corn, some dry spots will appear on the corn leaves. The dried spots could not be saved, but the corn seedlings could not die, and in a few days they would have new leaves. But the loss is certain.

Some growth-promoting regulators (such as robustin) may be sprayed.

If you spray a lot, then the corn seedlings will really die.

The state has banned the production and sale of paraquat, are you buying paraquat in **?

Paraquat was accidentally hit on corn, is there a rescue, how can corn be rescued just after paraquat is played? Paraquat is not saved by seeing the clear.

There is no way out. Don't waste time. Hurry. Cut him off in the bushes.

Can paraquat be used in cornfields? Paraquat is a contact herbicide that kills the green part of the plant on the ground and is passivated in the soil, and can be used in the corn field, but must be sprayed for weeds in the field and cannot be sprayed on the corn. Paraquat Corn paraquat is a contact herbicide pintongbi, which has a good killing effect on the green part of the plant aboveground, passivates into the soil, and can be used in corn fields, but must be sprayed for weeds in the field and cannot be sprayed on corn.

Summary. Paraquat is a broad-spectrum herbicide that kills a wide range of weeds quickly and effectively. But it also has a certain ***, which raises concerns about its safety.

Studies have shown that paraquat can have a toxic effect on insects, adversely affect the formation and quality of flower inflorescences, and also affect the growth of rice to varying degrees. Therefore, when using paraquat medicine, you should pay attention to the method of use and dosage, and do not overdo it. At the same time, it is necessary to pay attention to the sputtering and dialysis of the agent during the treatment process to avoid causing harm to yourself and the environment.

Hello dear<>

Fields covered with paraquat can have an effect on maize.

Paraquat is a commonly used herbicide that can cause toxicity to microorganisms, plants and animals in the soil, thereby affecting soil quality. In addition, paraquat remains in the soil and can be absorbed into the plant, adversely affecting the growth and development of the crop.

Therefore, before planting corn, you should choose a ground agitation block with no residual dust and herbicides in the soil, or choose other herbicides to treat it to ensure the healthy growth of corn pies.

Paraquat is a broad-spectrum herbicide that kills a wide range of weeds quickly and effectively. But it also has a certain ***, which raises concerns about its safety. Studies have shown that paraquat can have a toxic effect on insects, adversely affect the formation of flower inflorescences and the slippery stuffiness of flowers, and also have varying degrees of effects on the growth of rice.

Therefore, when using paraquat medicine, you should pay attention to the method of use and dosage, and do not overdo it. At the same time, it is necessary to pay attention to the sputtering and dialysis of the agent during the treatment process to avoid causing damage to itself and the environment. <>

Spraying paraquat in maize fields has two scenarios and two different outcomes:

1) When spraying paraquat, if the method is not done properly, or if there is wind, then no matter how high the corn grows, as long as the plant is contaminated with paraquat, it will cause serious post-jujube fruit, or form a pesticide damage, seriously affect the normal growth of the corn at the head of the pants, or die directly.

2) If paraquat is used for chemical weeding of corn fields in windless and sunny weather, as long as the directional spraying method is adopted, only the solution is sprayed on the weeds, and not on the corn plants, in this case, the yield will not be affected, unless there is a mistake in the operation.

Impactful. A glue of paraquat. He has spread to. Root. Ten Roots are damaged. Affect his growth.

The corn that is just about to be unearthed cannot be sprayed with this pesticide.

The sale and use of the herbicide in the country has been banned since July 2016.

Applicable crops. 1.Orchards, mulberry orchards, tea gardens, rubber gardens, forest belts are used

In the weeds are out of the qi and are in the vigorous growth period, use 100 to 200 ml of 20% water agent per mu, mix with 25 kg of water, evenly spray the weed stems and leaves, and when the weeds grow to more than 30cm, the dosage should be doubled. Destroy the macro and trap.

2.Corn, sugarcane, soybean and other wide row crop fields: can be pre-sowing treatment or post-sowing pre-seedling treatment, can also be used in the middle and late stage of crop growth, protective directional spraying to control weeds between rows.

Pre-sowing or post-sowing seedling treatment, 75 to 200 ml of 20% water solution per mu, and 25 kg of water spray to control unearthed weeds. During the crop growth period, 100 to 200 ml of 20% water agent per mu, mixed with 25 kg of water, was used for protective directional spraying between rows.

3.Practical experience shows that the herbicide has no obvious effect on Rehmannia rehmannia.

Precautions: Do not drift the liquid medicine to the fruit tree or other crops when using, and the vegetable field must be used when there are no vegetables.

The spraying should be uniform and thoughtful, and laundry detergent can be added to the liquid medicine to improve the adhesion of the solution. 30 minutes after application, the effect of the drug can be basically guaranteed when it rains.

Features: the active ingredient has a strong destructive force on the chloroplast membrane, so that photosynthesis and chlorophyll synthesis are quickly stopped, and the leaf begins to be damaged and discolored 2 to 3 hours after the treatment, the herbicide has a strong destructive effect on the green tissue of monocots and dicots, and has a certain conduction effect to destroy the green plant tissue, but can not penetrate the embolized bark, and it is easy to be passivated after contacting the soil. It can not destroy the roots of the plant and the seeds hidden in the soil, so the weeds have the phenomenon of regeneration after application.

The herbicide becomes inactive on contact with soil and is removed 1 to 2 days before sowing.

The leaves turn yellow 2 to 3 hours after treatment, and the whole plant dies 3 to 4 days;

The weeding effectiveness is related to the weather, and generally sunny days are better than cloudy days;

There is no systemic conduction.
