Can you apply herbicides to peanuts during flowering, and can you apply herbicides after peanuts flo

It is recommended to start beating at the beginning, so that the peanut can grow better at the beginning, and when the grass starts to grow, it will already be quite tall, and win in the competition for sunlight and nutrients, inhibiting the growth of the grass. In this way, the grass can not be said to be none, but it grows relatively sparsely, if it is not planted, it can be done by hand, if the planting area is too large, it is recommended to kill it again.

Peanuts should not be treated with herbicides during flowering.

Because peanuts are sensitive to herbicides during the flowering period, they can cause abnormal pollination and fertilization, resulting in shrinkage and deformity of the grains. Generally, weeds should be done at the 2-4 leaf stage, sprayed before 10 a.m. and after 4 p.m. Remember to dilute it twice when spraying, and don't spray it when there is water in the field, rain, or dew on the leaves.

1.Can peanuts be treated with herbicides during flowering?

Many people wonder if peanuts can be sprayed with herbicides during the flowering period. In fact, it is not recommended to spray herbicides at this time. It is important to know that peanuts are sensitive to herbicides during flowering. At this time, the use of herbicides is easy to cause abnormal pollination of peanuts and easy to wilt and deform peanuts.

Therefore, for the healthy growth of peanuts, it is best to avoid the flowering period when killing herbicides. Generally, we spray herbicides when the flowers have grown 3 true leaves and the weeds have grown 2-4 leaves. Spraying is better at this time.

When spraying herbicides on peanuts, it is recommended to avoid the high temperature stage at noon, so as to avoid the evaporation of herbicides caused by high temperatures, which is not conducive to the weeding effect. So it's best to apply the herbicide before 10 a.m. and after 4 p.m. Be careful not to mix herbicides and fertilizers, otherwise it will affect the weeding effect.

To avoid pesticide residues from herbicides, safety control agents for amfargo herbicides can also be used.

Herbicides can be applied after the flowering period, but not during the flowering period.

Peanuts can not be herbicides during the flowering period, because peanuts are sensitive to herbicides during the flowering period, and herbicides will cause abnormal pollination and fertilization, causing deflated grains, deformed grains and other phenomena. Generally, it is more appropriate to spray herbicides when the flowers grow 3 true leaves and weeds 2-4 leaves, spraying before 10 o'clock in the morning or after 4 o'clock in the afternoon, and do not spray when there is water in the field, rain and dew on the leaves.

How to manage peanuts during flowering and fruiting.

1. Drought resistance and seedling protection.

Although peanuts are drought tolerant, if the soil moisture is insufficient to demand water, it will inhibit the growth of peanuts and affect their flowering and fruiting. When the soil is too dry, the flowering rate of peanuts will decrease significantly, and when it is severe, it will stop flowering. Moreover, the fruit needles in the soil cannot expand normally, which affects the development of the fruit.

Therefore, if the soil moisture content is insufficient, then it must be watered in time, and the watering is mainly sprinkler irrigation. It not only saves water, but also ensures that water can be smoothly infiltrated into the soil.

2. Foliar top dressing.

After the peanut seeds are planted, all the nutrients that were originally stored in the peanut seeds will be consumed about a week after the emergence of the seeds. At this time, the roots of the seedlings do not have sufficient nutrients for the growth and development of peanuts. And it will also affect the reproduction of rhizobia in the roots, and the peanut plant is in the critical period of growing branches and leaves, flower bud differentiation and so on, which also needs a lot of nutrients.

Therefore, after peanuts enter the flowering period, the demand for fertilizer will be further increased, and it is necessary to pay attention to the amount of nutrients supplemented, mainly foliar top dressing, and fertilizer can be mainly potassium dihydrogen phosphate in Trim.

3. Cultivating and weeding.

After the peanut enters the flowering period, we should also pay attention to the work of cultivating and weeding. The main purpose of cultivating is to improve the permeability of the soil, soften the soil, promote the growth of peanut roots and nutrient absorption, and provide guarantee for peanut flowering and fruiting. And this is very beneficial to peanut fruit needle pricking, but also can improve the fruit range and yield of peanuts.

In tillage, we should also do a good job of weeding to avoid excessive weeds in the field resulting in the loss of too many unnecessary nutrients, and the flowering and fruiting rate of peanuts.

4. Pest control.

During the flowering and fruiting period of peanuts, the control of pests and diseases is also very important. Pests and diseases will have a great impact on the flowering and fruiting of peanuts, among which the common pests and diseases in the flowering and fruiting stage of peanuts are leaf spot, stem rot, cotton bollworm and so on. Most of these pests and diseases are mainly affected by peanut stems, leaves and fruits.

Therefore, we must pay more attention to different pests and diseases to use different agents for control, such as leaf spot disease is generally used Obo or carbendazim, and stem rot is mainly based on root Yibi or copper acetate.

After the flowering period of peanuts, herbicides can not be used, and the temperature is too high, and the herbicide nicosulfuron after seedlings in maize fields is easily affected by high temperatures.

Peanuts should not be used as herbicides during flowering. 1.About 20 days after the first flowering of peanuts, spray peanuts finely with 10 20 milliliters of gibberellin.

In addition, spray peanuts during the flowering period. Generally, when the first flowering is 10-15%, the second time is around the 25th. If the weather is good, when spraying nutrients, it can be mixed with fungicides, such as 50% carbendazim, 2 taels per mu, three basins of water, or tobol.

2.Herbicides are substances that kill or inhibit plant growth by killing or selectively killing weeds. Herbicides are also called herbicides.

Herbicides have the characteristics of high efficiency, low toxicity, broad spectrum and low dose. According to its action characteristics, it can be divided into selective herbicides and fungicidal herbicides. Peanuts are sensitive to herbicides during the flowering period, and herbicides will cause abnormal pollination and fertilization, and the phenomenon of deflated grains and deformed grains will appear.

3.Peanuts are rich in fatty oils, which can moisten the lungs and relieve cough. It is often used for chronic cough, asthma, sputum production, and blood diseases.

The linoleic acid contained in peanut oil can decompose cholesterol in the human body into bile acids and excrete them from the body, thereby avoiding the deposition of cholesterol in the human body and reducing the incidence of various cardiovascular and cerebrovascular diseases caused by cholesterol exceeding normal values in the human body.

Peanuts are not suitable for herbicides during flowering period.

Peanut herbicide.

Chemical weeding of peanuts is divided into closed weeding after sowing to before emergence and post-emergence weeding after emergence.

Closed weeding, acetochlor, metolachlor, sec-butylin, etc. can be used for soil sealing treatment.

For post-seedling weeding, quinoxalin and high-efficiency flupyrimethoxalin can be used to control grassy weeds such as Vulgaris and Barnyard grass at the 2 to 4 leaf stage of weeds, and pesticides such as lactoxafen and ethoxyfluorfen can be used to control broad-leaved weeds such as Amaranth retroflexus and Amaranth macrodont.

Closed herbicide formula:

After sowing peanuts to the front hole seedlings, the method of closed weeding can be adopted, and the specific methods are as follows:

To control grass-based weeds, 45 to 60 ml of 960 grams of metolachlor EC can be used per mu, or 150 to 200 ml of 33% pendimethalin EC per mu, mixed with 40 to 50 kg of water, mixed evenly and sprayed;

Hekuo double removal formula: 150 to 200 ml of 51% acetochlor (acetochlor and prometrinet) emulsifiable silver can be used per mu, mixed with 40 to 50 kg of water, mixed evenly and sprayed.

Post-seedling herbicide drug formula:

After the peanut emerges, post-emergence herbicides can be sprayed when the weeds have grown to 3 to 5 leaves.

Control of grasses-based weeds: 43 to 54 ml of 10% quinoxalin emulsifiable concentrate per mu, 30 to 45 kg of water, mixed evenly and sprayed.

Hekuo double removal formula: 15% quine-flusulfonamide (quine-flusulfafen) microemulsion can be used per mu, 100 to 120 grams per mu; Mix 3045 kg with water, mix well and spray.

Hello, you can't hit it at any time, you can hit it like grass and die, and you can hit it when it doesn't sprout.

Peanuts should not be herbicide during flowering.

Because peanuts are sensitive to herbicides during the flowering period, it will cause abnormal pollination and fertilization, causing deflated grains and deformed grains. Generally, it is laid in the 2-4 leaf stage of weeds, and it is advisable to spray before 10 am and after 4 pm. When spraying, remember to dilute it twice, and do not spray when there is stagnant water in the field, rain on the leaves, and dew.

1. Can herbicides be applied during the flowering period of peanuts?

Many people want to know whether peanuts can be herbicide in the flowering stage, but in fact, it is not recommended that everyone spray herbicides at this time. It is important to know that peanuts are sensitive to herbicides during flowering, and herbicides at this time are easy to cause abnormal pollination of peanuts, and peanuts are prone to deflated grains and deformities.

Therefore, for the healthy growth of peanuts, it is best to avoid the flowering stage when applying herbicides. We generally spray herbicides when the flowers grow 3 true leaves and the weeds have 2-4 leaves, and the spraying effect is better at this time.

When spraying herbicides for peanuts, it is recommended to avoid the high temperature stage at noon, so as not to cause the herbicide to evaporate due to high temperature, which is not conducive to the weeding effect. So it is better to apply herbicides before 10 a.m. and after 4 p.m. Be careful not to mix herbicides with fertilizers, otherwise it will also affect the effectiveness of weeding.

In order to avoid herbicide residues, Anfargo herbicide safety control agents can also be used.

It cannot be beaten and will affect pollination.

Summary. Dear, you can use it, and it is recommended to use quinoxalin herbicide at the seedling stage of peanuts. Generally, flusulfafen can be added with quinoxalin.

Weeding before seedlings in peanut fields. The planted peanuts can be divided into spring peanuts and summer peanuts, that is, early peanuts and late peanuts. Early peanuts can be planted at the beginning of spring, and late peanuts are generally planted after the wheat is harvested.

The planted peanuts can be divided into spring peanuts and summer peanuts, that is, early peanuts and late peanuts. Early peanuts can be planted at the beginning of spring, and late peanuts are generally planted after the wheat is harvested.

After peanut emergence, during the four-leaf period of weeds, spray 40 ml of 25% sulfafen water solution with 30 kg of water to control broad-leaved weeds; 40 ml of quinoxalin emulsifiable concentrate or 40 ml of high-efficiency mulberry emulsifiable concentrate mixed with 30 kg of water are used to spray to prevent sharp-leaved weeds. Peanut seedlings can be used with herbicides that can be used in broad-leaved crops such as grass cover, quinoxalin, and pine weedicide.
