Will herbicide spraying in wheat with foliar fertilizer be more effective in weeding?

When it comes to spraying herbicides, many farmers are worried about poor weeding effects and pesticide damage. It is a good time to spray herbicides in wheat fields, weeds in the wheat field are in the seedling stage, the roots are small, the leaves are tender, and the wheat is small, and the weeds will not be blocked, so the effect of spraying herbicides is better.

Because of late sowing, the wheat seedlings in many plots are small, and the temperature drops early, and the temperature changes greatly, resulting in unsatisfactory effects after spraying herbicides. Some farmers asked whether foliar fertilizer would improve the weeding effect if foliar fertilizer was added when spraying herbicides on wheat, and it could also save labor and not miss the best time for weeding.

Spraying foliar fertilizer before winter can promote the growth of seedlings, improve cold resistance, and ensure the safety of seedlings in winter. Some farmers believe that adding foliar fertilizer to herbicides can improve the weeding effect, because the activity of weeds is improved, and the herbicides absorbed are more, and weeds will naturally die, such as adding potassium dihydrogen phosphate and brassin. When spraying herbicides, it is not recommended for farmers to add any foliar fertilizer, which will aggravate the occurrence of pesticide damage.

There are several reasons for this:

1. There are broad-leaved weeds in wheat fields before winter, as well as gramineous weeds that grow at the same time as wheat, and the seedlings are similar in size and are not easy to distinguish. When we spray herbicides, we require uniform spraying, and the main target is weeds on the ground. Foliar fertilizer is added to herbicides, which has a certain effect on weeding.

However, when spraying in the whole field, it also has a certain impact on the growth of wheat seedlings. While we weed, we can't hurt the wheat seedlings, so it is not recommended to mix them.

2. When spraying herbicides on wheat, sufficient water consumption is required to have a good weeding effect. If you add foliar fertilizer, or increase yield, it is difficult to mix the liquid medicine evenly, and some places spray with a large concentration, which is easy to have pesticide damage, and some have a small concentration and poor weeding effect. In order to ensure the effectiveness of weeding, it is recommended that the herbicide be sprayed separately.

If mixed with different herbicides, be sure to use them correctly!

3. The growth of wheat seedlings in some plots is weak, and there are yellowing and dry tips. Some farmers are thinking of spraying herbicides and foliar fertilizers, which can not only control weeds but also promote the growth of seedlings. In this case, it is advisable to postpone the use of herbicides, spray foliar fertilizer first, cultivate strong seedlings, and then spray herbicides.

If it is sprayed directly, the wheat seedlings with weak resistance are prone to pesticide damage.

When the wheat seedlings grow normally, it is recommended to weed first, because the herbicide has temperature requirements, and when the average daily temperature is lower than 10, it can only be used after the year. So, weeding first, then spraying foliar fertilizer, or increasing yields**. Herbicides are also not recommended to be mixed with fungicides and insecticides.

When pests and diseases are severe, the use of herbicides should also be postponed.

Yes. Because wheat herbicide sprays combined with foliar fertilizer not only get rid of most of the weeds, but also make the wheat grow better, the effect will be better.

The weeding effect is not particularly good, adding foliar fertilizer will make a lot of grass more tenacious, and the effect of herbicides is not so good.

The effect will be better, it will allow the seedlings to grow more robust, and then it will also improve the cold resistance, which can prevent insect pests.

Yes, if you spray some herbicides, the weeding effect will be better, there will not be too many problems, and the wheat will have a higher yield.

Wheat field agents are used in two peak periods, one is from mid-November to the end of December before the year. The second is from the end of February to the end of March after the new year. However, wheat field herbicides are still the best before winter, grass age is small and easy to eliminate, after the application of pesticides, one is that the grass is difficult to remove, the other is the amount of medicine, the effect can not reach the effect of the previous use, and it is easy to cause herbicide residues, so it is recommended to use the herbicide before the year, and the wheat field herbicide can be used at a temperature of 8-10 degrees.

Wheat weeds have always had a great impact on the growth of wheat, and it is difficult to remove weeds in wheat fields and grow fast, so spraying herbicides must be selected at the right time. Let me introduce it to you.

Wheat herbicide application time: the application period is the early stage of wheat tillering before winter and wheat jointing in the second year. The effect of drug control at these two times is better, and it is relatively safe for wheat, and the effect is poor if it is late, among them, the earlier the 2,4-d butyl ester is used, and besulfuron is used before getting up after the wheat returns to green, so as not to cause pesticide damage to the next crop.

To apply herbicides to wheat, it is necessary not only to master the time, but also to master the temperature and humidity when using herbicides: the average temperature when using herbicides should be above 6, which will achieve very good control results. For example, besulfuron is sensitive to temperature, and the prevention and control effect can only be shown after 15-20 days or even 30 days after the drug under low temperature conditions.

In addition, herbicides should be used on sunny days and slightly higher temperatures, generally from 10 a.m. to 3 p.m. In case of dry soil, herbicide application should be increased to ensure the control effect.

Can wheat herbicides be treated with disease prevention and foliar fertilizer? Well, it is generally not recommended to divide the except. Herbicides are mixed with other pesticides to prevent the effects of herbicides or damage to wheat.

However, in order to reduce the number of spraying, herbicides are often mixed with other pesticides. So, what's going on?

<> the current wheat herbicides are basically selective herbicides, and the wheat that is resistant to herbicides can decompose its virulence by itself or decompose its toxicity, and will not be poisoned by the drug, but the size of the decomposer itself is not only related to the characteristics of the variety, but also related to the growth of wheat and temperature, moisture, etc., the wheat grows robustly, and the root system is generally more developed; The stronger the leaf photosynthesis, the smaller the effect on the operation of wheat self-assimilated substances. It can be mixed, but it should be carried out according to the actual situation, and the useless ones should not be mixed.

Herbicides are specifically foliar sprays on grasslands, while insecticides, fungicides, and foliar fertilizers are flocking to wheat seedlings, which are counterproductive and cannot be mixed. Herbicides should be used alone, and insecticides, fungicides, and foliar fertilizers can be mixed. It can be mixed, but it depends on the actual situation.

In order to mix various fungicides and yield enhancers, it is best to add"Rhodiola rosea", supplement various trace elements, improve disease resistance, frost resistance, drought resistance. If your herbicide is mixed without specific warnings"Penetrants"or"Foliar fertilizer"(a mild product that is relatively neutral).

No, because it is not conducive to increasing the yield of wheat, and it is not conducive to promoting healthy growth of wheat, and if the situation is severe, it can also cause pests and diseases in the wheat, and it may also dry up the wheat.

No; For the control of wheat, try not to mix some disease prevention drugs and fertilizers, because the objects of their control are different.

No; General herbicides should never be mixed with other things, otherwise the herbicide will lose its effectiveness.

<> wheat herbicides should not be mixed with foliar fertilizers. In severe cases, not only is weed control not in place, but also pesticide damage may occur in wheat. When spraying herbicides, wheat growers should not mix with foliar fertilizer, herbicides can be used alone to improve the weeding effect, and the use of foliar fertilizer can be used to return to a single spray.

There is no fixed time and frequency of use of foliar fertilizer, and it is enough to supplement the proper nutrition according to the specific growth of wheat.

1. Can wheat herbicides be mixed with foliar fertilizers?

1. Wheat herbicides cannot be mixed with foliar fertilizers. Generally, in severe cases, not only the effect of weed control is not good, but also the wheat may also be damaged by pesticides. When the herbicide and foliar fertilizer are mixed, the focus of the spraying site will be unclear, and if the wheat has yellowing, its own resistance is weak, and the probability of pesticide damage will increase when exposed to too many herbicides.

And hunger. 2. Wheat growers must not be mixed with foliar fertilizer when spraying herbicides, and generally herbicides can be used alone, so as to improve the weeding effect. The use of foliar fertilizer can be sprayed alone, and can also be used with herbicides and fungicides.

3. There is no fixed time and frequency of use of foliar fertilizer, and it is generally supplemented with due nutrition according to the specific growth of wheat. It is important to note that herbicides should not be mixed with insecticides and fungicides.

Second, when is the right wheat herbicide

1. Wheat herbicides are generally used in two periods (before and after the year), which are two time periods of wheat seedling stage and wheat regreening period, and the wheat seedling period in most areas is around late November, and the wheat regreening period is between late February and early March. It is more appropriate to use herbicides in these two time periods, and the control effect is better at this time, but for some areas that are sown too late, it must be decided according to the specific growth of local wheat.

2. Generally, wheat before the 4-leaf stage is relatively delicate, and the detoxification ability and immunity will be very low, and it is easy to produce pesticide damage. After the jointing stage, the wheat will enter the booting stage and is more fragile, at this time, the use of herbicides is easy to produce pesticide damage, especially dimethyltetrachloride, which will cause the wheat ears to be unpumped or deformed, which will seriously affect the wheat yield.

3. The herbicide in low temperature weather, the control effect will be very unsatisfactory, must be used in the daily average temperature above 6 °C, about 10 a.m. to 3 p.m. Because the weeds absorb light at this time and grow vigorously, the stomata will gradually open, and it is easy to absorb water and liquids, and the low temperature will be the opposite, so the better weeding effect can be achieved.

Summary. Kiss! Hello, happy to answer your <>

Pro-wheat can generally be herbicide after 7 days of fertilizer, at this time the wheat is in the 4-leaf or 4-leaf 1-heart stage, and is more tolerant to herbicides, so it is safer to use herbicides at this time. In addition, when the wheat is 4 leaves, most of the weeds have come out, and the grass age is small, the wheat has no tillering, and there are not many leaves, so it is easier to kill weeds with herbicides, and the efficiency will be higher.

How Long After Fertilization Of Wheat Can You Spray Herbicides.

Kiss! You're glad to answer your <>

Pro-wheat can be herbicide after 7 days after sprinkling the fertilizer wheel, at this time, the small tung burning wheat is in the 4 leaves or 4 leaves 1 heart stage, and it is more tolerant to herbicides, so it is safer to play herbicides at this time. In addition, when the wheat is 4 leaves, most of the weeds have come out, and the grass age is small, the wheat has no tillering, and there are not many leaves, so it is easier to kill weeds with herbicides, and the efficiency will be higher.

Do you have any other questions?

Wheat is weeded first and fertilized first.

Pro-can first play herbicide after top dressing the point of view of wheat back to green, the weeds in the field are also prepared to return to green, the weeds that have not emerged also begin to emerge, wheat herbicide wants to improve the weeding effect, spraying time is very critical, while the weeds have just returned to green, and the weed seedlings that have just emerged, their own resistance is weak, and the herbicide spraying will improve the weeding effect. If it is topdressed first, the wheat will absorb the fertilizer, and at the same time, the weeds will also absorb, which improves the resistance of the weeds themselves and reduces the weeding effect. The point of view of first topdressing and then herbicide is that after topdressing wheat in the green period, it is conducive to the rapid recovery of normal growth of wheat, especially after a winter, wheat is easy to occur seedling yellowing, seedling weakness, wheat at this time, its own resistance is weak, if spraying herbicides, the probability of wheat damage will be greatly increased.

In addition, from another point of view, after spraying herbicides, weeds first absorb the herbicide solution, and then absorb the fertilizer, which will also reduce some of the weeding effect.

Wheat can be sprayed with herbicides on the same day after foliar fertilizer.

Except for alkaline or copper-containing herbicides.

How to use wheat herbicides

Temperature. 1. Generally, when the average temperature is higher than 6, the control effect of herbicides is better, and benzuron-methyl and other agents are sensitive to temperature, and under low temperature conditions, 15 to 20 days after spraying, or even 1 month later, will have a better control effect. Herbicides need to be used when the orange is sunny and the temperature is slightly higher, generally at 10 a.m. or 3 p.m.

2, the wheat herbicide should not only master the temperature, but also to master the time, generally wheat herbicide suitable time is the wheat tillering period before winter, and the early stage of the second year of wheat jointing, these two periods of herbicide control effect is better, the wheat is also safe, if the time is late, the effect will be poor, the "2,4 to d butyl ester" herbicide the sooner the better, besulfuron in the wheat after the green before getting up to use better, can avoid pesticide damage to the next crop.

The use of wheat herbicides is generally carried out when the local average daily temperature is stable above 6, and the spraying wheel has the best effect when the temperature is about 10.

Combination recipes. 1. For the prevention and control of broad-leaved weeds such as humulus, camellia, Maijiagong, Artemisia annua, ionic grass, etc., 75% benzuron water-dispersible granules can be used, with a suitable dosage of 1g per mu, or 10% besulfuron wettable powder, with a suitable dosage of 10g per mu.

2. For the prevention and control of Grass grass, 70% fluzosulfuron water dispersible granules can be used, and the appropriate dosage per mu is 3 to 4g.

3. For the prevention and control of bowl flowers, 20% chlorofluoropyroxyacetic acid emulsifiable concentrate can be used, and the appropriate dosage per mu is 50 to 70ml.

4. For the prevention and control of Vulgaris and Mai Niang, 15% alkynyl ester wettable powder can be used, with a suitable dosage of 30 to 40g per mu, or emulsifiable concentrate of emulsifiable cocozole, with a suitable dosage of 30 to 40ml per mu.

5. For the prevention and control of the mixed growth of finch wheat grass and broad-leaved weeds, 3 to 4g of 70% fluzosulfuron water dispersible granules and 10g of 10% benzensulfuron wettable powder can be used per mu.

6. The above formula needs to be mixed with 60 to 80 kg of water per mu, and it can be sprayed evenly with spraying trucks and hand pressure sprayers.
