What are the effects of uneven herbicide spraying on plants?

If the method is not done properly, it will definitely have an impact. Water from herbicides flowing into someone else's farmland can damage someone else's crop. This kind of thing happens when the countryside is torn apart.

Spraying herbicides and staying close to other people's fields will not cause damage to the crops in other people's fields as long as you pay attention to the following two points. It is best not to spray on windy days. Under the action of the wind, the moisture containing herbicides drifts relatively far and is easy to fly to other people's land.

Spraying herbicides, when approaching other people's crops, lower the nozzle as much as possible so that the outlet of the nozzle is facing your own land, so as not to spill the medicine on other people's fields.

The effect of herbicide spraying in rice paddy fields has no effect on the same crop, different plants not only have an impact, but also cause a destructive attenuation, and different types of weeds sprayed with herbicides can have serious consequences. Herbicides are also becoming more and more symptomatic. When buying a spray, you can't just look at the type of weed.

To see the object of the sprayed crop, measure it in both directions.

The symptoms of herbicides are also becoming stronger, and the scope of application of trademarks has also been clarified. Removes the same weeds (e.g. wild oats), but there are also suitable crop targets. If it is a herbicide suitable for spraying wild oats in rape fields, it cannot be sprayed in wheat fields to remove wild oats, which can cause harm.

At the border of my house, a neighbor said that when the wild oat herbicide is sprinkled on the rapeseed (rapeseed green morning) next spring, when the wheat is green with the Yangjiao wheat (when the wheat is green), the Yangjiao wheat (about 40 centimeters wide) has withered, but the rapeseed of others is not damaged at all.

Looking at the applicable properties of herbicide arable land and field, some herbicides are mainly toxic to perennial stubborn weeds, and the annual weeding speed is fast, and it also has a fatal effect on food crops. It is generally suitable for perennial weeds, not fields, but most people also apply to the killing of perennial stubborn weeds on the ridges of crops and ditches. No wind should blow during the spraying process.

The use of herbicides has seriously led to the loss and extinction of biodiversity, and it is hoped that the relevant authorities will ban their production and use.

Some farmers, because the field is far away from home, it is difficult to pull water with a car, or in order to save physical energy and other reasons, the use of ultra-high concentration spray, due to the amount of water added is too small, the field pesticide application is uneven, the phenomenon of heavy spraying and leakage spray is more serious, the grass shortage occurs at the leakage spray, and the pesticide damage will inevitably occur at the heavy spraying place. The third is that the application time is too late to cause pesticide damage.

If the herbicide is sprayed unevenly, it may lead to the destruction of the land, and other things planted in the land may not grow crops in the future.

Uneven spraying is caused by impurities are not clean, as the so-called cutting of grass is not exhausted, and the spring breeze blows and grows. Second, accidentally touching the vegetation of crops will also cause the death of crops, so that the cart is not turned upside down, and the gains outweigh the losses.

In fact, for most farmers, they usually use some herbicides when they plant something. Then we will also find that after using herbicides, the effect of such herbicides will also be affected by some factors, so we can pay attention to some things when using herbicides to ensure the effect of herbicides. We will also find that herbicides are actually effective means of controlling weeds, and for herbicides, they are not very effective after simply spraying.

It will be affected by the temperature of the air.

Instead, it needs to be fused with air, oxygen, and some other moisture and soil to play an important role. And there are many factors that can affect the effectiveness of herbicides. First of all, temperature is an important factor in the effectiveness of herbicides.

If we find that the temperature is getting higher and higher, the spray will soon evaporate. Especially for some chemicals that are very volatile, once there is an effect such as photodecomposition, it will make some such herbicides actually have no effect. <>

It can also be affected by the humidity it is exposed to.

Even after spraying, it will not have a certain effect on pests, including for some such weeding effects, it is also very insignificant. So we also need to choose some good herbicides, and we need to store them at low temperatures. There is also the need for us to have a reasonable way to preserve such herbicides when we use herbicides.

If the humidity is too high, it will also affect the effectiveness of the herbicide. After all, for herbicides with more significant efficacy, they need to be combined with a certain amount of moisture in the air in order to play an effective role. If the herbicide is exposed to too much moisture, it will cause the herbicide to fail prematurely.

It will be affected by weather factors, such as windy days, rainy days or hot weather, and then also the surface temperature, as well as the planting environment, and then also the type of agricultural products planted.

It will be affected by sunlight, temperature, humidity, soil pH, and improper use of herbicides in the process of using herbicides, and the concentration will also be affected.

It will affect the growth of crops, it will cause pesticide damage, it will also affect the fertility of the soil, it will also cause a large number of plant deaths, and if the concentration is not grasped properly, it will affect the final yield.

The problem of temperature, the problem of humidity, the problem of soil, the problem of service life, the problem of proportion, the problem of operation, these will have an impact.

Different herbicides have different requirements for the growth period of weeds. For example, soil sealants require pre-bud medicine, and the efficacy of weeds is not good after they are unearthed. Post-emergence herbicides require weeds 3 5 leaf base drugs, the initial age is too large, and the efficacy is not good.

For example, in the production area of winter wheat, the application time of drugs is divided into pre-winter reagents and post-use drugs. In order to exert the efficacy of herbicides, there must be a proper temperature, and the use of drugs at low temperatures will reduce the effect of weeding, and wheat poisoning will occur in severe cases. If you apply the medicine before winter, it is best to use a product that is resistant to low temperatures.

If you want to use the medicine after the holiday, it is safest to sprinkle the head water (first water) after the winter wheat is sown and apply the herbicide 40 days later.

Summary. Hello dear! <>

Considering that it does not affect the stubble, it is recommended to use a heat suppressant, which has a long-lasting effect and can effectively inhibit the weeding root system before the stubble, in order to reduce the adverse effects on the residue of the stubble and hinder plant growth after spring sowing. Specifically, heat suppressants control the development of weedicidal roots by inhibiting and inhibiting the growth of herbicidal plants in the growth organs of herbicidal plants, rather than inhibiting root cell activity and reproduction. Therefore, the herbicide can effectively destroy the root system before the herbicidal plants germinate, so as to achieve a non-toxic and harmless weeding effect.

A herbicide that can control weeds and roots without affecting the stubble.

What herbicide can kill the seedlings and seedlings will not affect the next planting.

You can buy it there.

Hello dear! <>

Seedlings can be weed with the herbicide benzoxacide or its grandson nitrate pesticides, which can effectively remove weeds from seedlings without affecting the next planting. However, it should be noted that this type of herbicide has a certain residual period, so the residual period of the herbicide should be released before use, and if the residual period is confirmed to be appropriate, it is safe to use the herbicide to control weeds.

Okay, thanks.

Pusit, Saike, Kuaicho, Beanhuanglong, atrazine, these herbicides will be affected, and they must be used with caution.

1) Rapid barnyard (dichloroquinolic acid), according to the United States, no crops other than rice can be planted within 309 days after the application of fast barnyard barnyard except rice; Eggplant and tobacco cannot be planted within 12 months; Tomatoes and carrots cannot be planted within 2 years. Umbelliferae crops, such as carrots, celery, coriander, etc., are sensitive to fast-killing barnyard and should be careful not to cause drifting pesticide damage, and the above-mentioned vegetables should not be irrigated with water that is too fast-killing. (2) Cyke (methazine, azinone), according to the United States, if the dosage of active ingredients per hectare is 420 1120 grams, alfalfa, asparagus, barley, corn, grass, wheat, potato, red bean grass, tomato, sugarcane, soybean can be planted after 4 months; After 8 months, rice, cotton, and peas can be planted; After 12 months, crops other than roots can be planted; After 18 months, onions, sugar beets and other root crops can be planted.

The recommended dosage in Heilongjiang Province is 210 560 grams per hectare of active ingredient, which is generally safe for later cropping, but in arid areas, the content of soil organic matter is low, and the pH is greater than that of alkaline soil, the use of high dosage may cause pesticide damage to subsequent cropping sugar beets.

Prostec, chlorsulfuron-methyl, imidazole ethylnicacin, jade nongle, nicosulfuron-methyl, etc., these herbicides will affect crops.

Sulfafen, chlorsulfuron, Pusit, mimico, nicosulfuron, etc., these herbicides will affect the crop after the stubble, and will also affect the yield.

Pusit, clomisulfuron, beancaulon, metsulfuron, and Yunongle, these herbicides are very strong and will affect the crops in the later crops.

Growing crops and weeding is a relatively labor-intensive, labor-intensive and time-consuming job. With the application of herbicides, a lot of labor input is saved in weeding, but there are advantages and disadvantages. Although it saves labor and time, if the herbicide is applied improperly, it is easy to produce ***, causing damage to seedlings, and the gains outweigh the losses.

At present, there are many varieties of herbicides on the sales market, coupled with the long-term application of herbicides for weeding, the herbicide resistance to the working ability of wild grass or the working ability of herbicide tolerance has been greatly improved, in order to better achieve good weeding effect, the villagers who are engaged in planting and manufacturing are forced to increase the use of herbicides to achieve good weeding results.

As the saying goes, "it is three points of poison", the same is true for herbicides, there are almost no herbicides that are absolutely safe, which requires everyone to pay attention to the application of herbicides, bypass the crop seedlings, and prevent fertilizer damage.

Try to choose a certain kind of crop field herbicide, which is relatively safe. Some herbicide residues have a sentence period of nearly half a year. There are more highly effective herbicides, and the soil residue is more than 4 years at most.

Before choosing to spray herbicides, read the article to find out whether it will have an impact on the crops of the next crop, and then decide whether to spray. Herbicides do not have to be used casually, and the instructions for use are strictly followed.

Herbicides are generally not sprayed at the seedling stage, because such herbicides are eaten by grass or crops, if there are more weeds in the field, the sprayer can be used to spray the weeds as slowly as possible, and block the crop seedlings to avoid the drift of the liquid and cause harm to the crops.

Winter wheat before and after germination, until the regreening stage of wheat, the herbicide tolerance function is very strong, bract rice 3 5 leaf stage is to have a strong herbicide tolerance ability, weeds should be sprayed before 3 leaves.

When spraying herbicides, it is best to grasp the temperature within the range of 10 to 30 degrees to have a good weeding effect. Like the weeds in the winter wheat field, the temperature gradually from 6 degrees to the higher the temperature, the better the weeding effect, when spraying herbicides on summer corn, you should avoid the high temperature stage in the afternoon, and choose the early morning or evening when there is no wind to enter.

Spray herbicides when the soil is dry, do not spray herbicides before heavy rain, and do not spray herbicides when the wind blows, as the liquid drifts downwind, which will affect the safety of crop seedlings.

Consider the time and frequency of spraying, do not use high concentrations of herbicides, and also pay attention to the selection of varieties, and try not to choose the largest one.

It is necessary to pay attention to the way of using herbicides, but also to pay attention to the performance of herbicides, and to inject silver herbicides, and to inject liquid to match herbicides, and also pay attention to protecting their bodies.

1. First of all, the control of weeds in the field should be carried out as soon as possible, and it is best to control the weeds just before they are unearthed or when the corn seedlings are 3 leaves, because the weed resistance in the early stage is low, and the control is relatively easy.

2. Secondly, it is necessary to ensure the soil moisture in the field, you must know that the moist soil can be quickly absorbed by weeds after spraying herbicides, so as to achieve the effect of weeding.

3. Finally, it is reasonable to choose herbicides, and pay attention to the amount of herbicides, otherwise too much will affect corn seedlings, and too little will not have a weeding effect. For example, pre-seedling leakage which closed weeding, can be mixed with 26% thione-isoxazole suspension or 40% acetylene suspension, and then evenly sprayed, which has a good control effect on weeds, which is not only closed and weeded, but also effective for unearthed weeds in the later stage.
