Can herbicides be used in wheat fields now? What do I need to look out for?

Let's take a look at the herbicides used in wheat fields.

What is the method of weeding, and herbicides such as benzuron-on-methyl and quinoxalin are used in wheat fields.

Alkyne resin, fluzosulfuron, chlorofluoropyroxyacetic acid, etc., are all systemic conductive selective weed modifiers in leaf stems, according to the digestion and absorption of weed leaves and stems to the whole plant, after poisoning, Dingrui and meristems terminate growth and atrophy, and weeds slowly wither, therefore, one of the prerequisites for spraying herbicides is that weeds are still growing sluggishly at least, on this basis, the more abundant the growth of weeds, the better the adduction conduction, and the more the actual effect of extermination, on the contrary, the effect is poor.

Herbicides on wheat fields are not as effective as spraying before wheat regreening next year. The reason for this is that spraying only addresses a portion of the weeds in the wheat field today. In other words, a portion of the weeds that grow along with the rice seedlings.

When the weather warms up next year, new shoots will continue to emerge in the wheat fields. If you spray the pesticide next year, you can wipe out all the grass in the wheat field after the previous year, and you only need to apply the pesticide once. For the prevention of weeds in autumn and winter, it is best to choose in early November, when more than 90% of the weeds in the wheat field are excavated at the 2-4 leaf stage, <>

It is most ideal to carry out spraying. It should be noted that the drug must be dissolved twice after application, in addition, it must be selected on a windless day, the temperature in broad daylight is about 10, at least not less than 5, and it is strictly forbidden to take medicine when the temperature is greatly reduced. Due to the relatively low temperature recently, it is best to choose the afternoon if we are taking medicine, so that the actual effect will be stronger.

The use of herbicides in wheat planting has indeed saved a lot of things for our farmers. However, there is good and bad in everything. Herbicides are organic compounds, and if they are not handled correctly, they will cause fertilizer damage to the soil layer and wheat.

As a key crop, if herbicides are applied in the middle and late stages of wheat growth, not only will it have no practical effect on the growing weeds, but it can be digested and absorbed by the wheat, and the harmful components of chemical fertilizers will remain in the wheat. At present, the total number of weeds in the wheat field and the growth trend are not sufficient, and the resistance of weeds to herbicides is weak, and the amount of medicine is reduced. To grasp this beneficial opportunity, according to the type of weeds, choose the herbicide of Gate Feng Shui to exterminate the weeds in the wheat field.

Don't wait until after early spring, when the weeds are large and the weeds are old, take medicine to get rid of them!

Of course, this is possible, you must pay attention to the temperature outside, but also pay attention to the direction, you must do a good job of protective measures, pay attention to the scope of spraying.

Of course, it is possible, it should be determined according to the growth of specific plants, determined according to the use of specific herbicides, and must pay attention to safety issues.

Of course, it is possible, the use of different drugs is different, and it is necessary to pay attention to safety issues and proportions.

Dried wheat can be herbicide, rural spring brother planted more than 20 acres of wheat at home, has a certain understanding of planting wheat, now the farmland is basically mechanical operations, the speed is very fast,. First of all, wheat herbicides to look at the region, each region has, the gap between the north and the south is very large, Brother Chun is a native of Henan, according to the area of Henan wheat planting as the following, generally now the autumn harvest is faster, so wheat planting should be advanced, for now, winter wheat growth is relatively vigorous.

But the weather is getting colder and colder, and the basic grass is not coming out, so there is no herbicide before the year, and the temperature rises after the year, and the grass teeth are in front, and the herbicide can be played at this time, and the herbicide can be divided into two kinds, one is closed, which is a herbicide, regardless of whether it is drought resistant or not. Drought can be fought, the impact is not great, because the herbicide is sprayed directly on the grass, drought or not drought has nothing to do with it, it should be herbicide sprayed on the grass, different regions according to the actual situation to play herbicides, Brother Chun will share his experience with you, thank you for the invitation.

As the weather gets colder, the time to spray herbicides should also be suitable for wheat, and in some winter wheat areas, due to the dry climate, relatively little rainfall, and dry soils, some farmers do not know whether winter wheat can be sprayed with herbicides. Winter wheat is not suitable for spraying herbicides when facing soil drought, because the soil is dry, the weeds in the wheat field in order to reduce the evaporation of water, the respiratory function of the leaves is reduced, and the herbicide is sprayed on the leaves, the activity of the weeds is reduced, and the weeding effect is relatively poor.

If the winter wheat is planted earlier, the soil is dry, and there are more weeds in the field, herbicides must be sprayed before the year, and they should also be combined with watering, sprayed before winter, and after the Spring Festival, winter wheat enters the regreening period, and the appropriate field weed control enters the second stage. Spraying herbicides on wheat can only be used after mastering the elongation stage of winter wheat; At the same time, it is necessary to check the temperature above 7-10 degrees, the soil is dry, and the general soil moisture content can reach 40 60% to receive a better weeding effect.

No, because this is not conducive to increasing wheat production, and it is not conducive to the healthy growth of wheat, and if the situation is severe, it may lead to pests and diseases in the wheat.

Do not apply herbicides in times of drought; At this time, the effect of herbicide is not good, and it is easy to cause pesticide damage to wheat and affect its growth.

If the wheat field is dry, if there are weeds, you can apply herbicides, if there are no weeds, then you don't need to apply herbicides.

It is necessary to pay attention to the amount of herbicide used, pay attention to the conditions of weeding, pay attention to the growth of wheat, understand the disease phenomenon of wheat, pay attention to the use of herbicides, and pay attention to the effect of dilution.

First of all, the temperature must be strictly controlled, secondly, it is forbidden to use drugs in bad weather, and then, when using herbicides, you must pay attention to secondary dilution, etc.

Be sure to pay attention to the concentration of herbicides, do not let the concentration be too high, do not cause pesticide damage, and choose safe agents.

Summary. There are two main time periods for wheat to control weeds, one is when the wheat is in the tillering stage, that is, from mid-November to the end of December before the year, and the other is when the wheat is in the jointing stage, that is, from the end of February to the end of March of the second year. Under normal circumstances, after wheat jointing, the wheat field should not be sprayed again.

When spraying drugs, you should try to avoid low temperature weather (temperature below 10), as well as frost, rain, snow, hail, strong wind and other bad weather. When the soil moisture is 40-60%, it is conducive to the exertion of herbicide efficacy. 2. The reason is that spraying drugs in these two time periods is relatively safe for wheat, and most of the weeds have just been unearthed at this time, with poor pesticide resistance and better control effect.

Early spraying can effectively reduce herbicide residues and have less impact on crops.

Dear, I'm glad to answer for you: Can wheat seepage now be used to control weeds: can you play herbicides now, and spray herbicides on wheat to control weeds, generally choose to use when the wheat is in the tillering period, that is, from mid-November to the end of December before the year, or when the wheat is in the jointing stage, that is, from the end of February to the end of March of the second year.

There are two main time periods for wheat to control weeds, one is when the wheat is in the tillering stage, that is, from mid-November to the end of December before the year, and the other is when the wheat is in the jointing stage, that is, from the end of February to the end of March of the second year. Under normal circumstances, Li Feng argues that after the wheat jointing, the wheat field should not be sprayed again. When spraying drugs, you should try to avoid low temperature weather (temperature below 10), as well as frost, rain, snow, hail, strong wind and other bad weather.

The reason is that spraying drugs in these two time periods is relatively safe for wheat, and most of the weeds have just been unearthed when this is missing, the drug resistance is poor, and the control effect is relatively good. Early spraying can effectively reduce the residue of the herbicide and have less impact on the crop.

Can wheat be eaten in wheat grass after being inoculated with chlorofluoropyroxyacetic acid?

After the wheat has been injected with chlorofluoropyrooxyacetic acid, it is not edible in wheat grass, and it takes a period of time to slowly dilute and wash off the effect before it can be eaten.

Summary. Hello, you can fight, but you need to choose the right herbicide and application method according to the specific situation. First of all, wheat will be disturbed by various weeds during the growth process, which will affect its growth and yield.

Therefore, proper use of herbicides can effectively control the growth of weeds and improve the yield and quality of wheat. Secondly, it is very important to choose the right herbicide. The selection should be made according to factors such as the growth stage of wheat, the type of weeds, the toxicity of pesticides and the method of use.

Generally speaking, the growth stages of wheat are divided into seedling stage, jointing stage, heading stage and grain filling stage, and different herbicides need to be used at different stages. At the same time, attention should be paid to the toxicity of the agent to avoid adverse effects on wheat. The use of herbicides should be safe and environmentally friendly.

In the process of use, it should be operated in strict accordance with the instructions and relevant regulations to avoid harm to the human body and the environment. At the same time, attention should be paid to the residue of the agent to avoid affecting food safety.

Is it possible to control weeds of knotted wheat and buckwheat?

Hello, for the weeding of wheat, it is recommended to use glyphosate herbicides. Glyphosate is a broad-spectrum herbicide that can effectively control a variety of weeds, such as cereal, grass, and dogtail. Its mechanism of action is to block the metabolic process in the plant by inhibiting the 5-phosphoacylguanine synthase in the plant, resulting in plant death.

The use of glyphosate herbicide is to dilute the agent and spray it in the wheat field, generally at the jointing stage or filling stage of wheat. It should be noted that glyphosate has certain toxicity to wheat, so it needs to be used according to the dosage on the instructions to avoid damage to wheat caused by excessive use. The use of herbicides can not only improve the yield of wheat, but also reduce the labor cost of manual weeding and improve the efficiency of agricultural infiltration.

At the same time, it is also necessary to pay attention to the protection of the environment and human health, and avoid the harm caused by chemical residues to the environment and human body. The use of herbicides needs to be selected according to the actual situation, different crops and weeds need to use different herbicides, and they also need to be adjusted according to climate, soil and other factors.

Hail wheat is a winter crop that is sown in the fall, and seedlings usually appear within 1-2 weeks after sowing. In the wheat seedling stage, if there are too many weeds in the field, it will adversely affect the growth and development of wheat, so it is necessary to take weeding measures in time. Generally speaking, it is best not to apply herbicides in the seedling stage of wheat, because herbicides will cause certain damage to wheat seedlings and affect their normal growth.

If weeding is necessary, it is recommended to wait until the wheat has grown to the 3-4 leaf stage. At this time, the wheat has grown more leaves and can withstand certain herbicide damage. When applying herbicides, they should be carried out in accordance with the instructions for the use of the pesticides, and should not be used in excess.

At the same time, it is also necessary to pay attention to the impact of herbicides on the environment and human body to maintain safe use. If you are not familiar with the use of herbicides and precautions, it is best to consult a professional.

The main reason for spraying herbicides during the growth period of wheat is that the seedling stage and regreening stage of the young brother are at the jointing stage, which is likely to enter the young panicle differentiation stage, which affects the growth of wheat.

Seedling stage: Wheat weeding is carried out around November.

Regreening period after the New Year: Weeding is generally carried out in 2-3 months after the New Year. At this time, the weeds are generally larger, especially when many farmers sow seeds late, and some farmlands do not have the conditions to spray herbicides before the year, and need to be sprayed after the year.

1.Temperature conditions.

The weeding temperature of wheat field is generally better when it is high, not only the absorption effect is good, but also it is not easy to cause pesticide damage. In winter, the average temperature will be lower than the humidity, which will affect the effect of wheat weeding, and if it is lower than 5 degrees, there will be a critical probability of dispersion. Roll the suspicion.

Therefore, you can wait until the temperature rises to carry out weeding, spray after 10 am and before 3 pm when the temperature is high and the weather is clear, which can ensure the effect and reduce the damage of the pesticide.

2.Fertilizer conditions.

Fertilizers such as phosphorus and potassium can be added to make wheat grow more robust.

1.Look at the timing of application.

If the weeds do not germinate in winter, you can go to a professional pesticide agency for consultation, and weeding is a critical time at this time.

2.Look at weed resistance.

On the premise that some weeds have developed resistance in the late period of weeding, different formulations of herbicides can be selected.

If there is any problem with the wheat you grow and you need to buy herbicides to clean up, you must go to a professional herbicide company for consultation, and you can't spray herbicides casually according to your own ideas, if you spray herbicides casually, it may affect the growth and yield of wheat.

1.Dry seeds in advance.

Before planting wheat, the seeds should be dried three days in advance, the speed of seed emergence will directly affect the growth of wheat seedlings, the slower the emergence, too much nutrients will be consumed on the way, and it is easy to be harmed by infectious diseases. Therefore, it is necessary to choose high-quality seeds and dry them in advance to germinate faster.

2.Pay attention to the depth of seeding.

When sowing, it is necessary to pay attention to the depth control of about three centimeters, which is easy to absorb water, and it is also conducive to the unearthing of seeds.

3.Pay attention to the seedlings.

After wheat sowing, the emergence of seedlings should be checked in time, and once the lack of seedlings is found, it should be filled in time and replanted.
