How to control the bean stem fly of snow peas?

In normal times, the land should be managed in a timely manner, and then the soil of the land should be sterilized, and pesticides to prevent pests and diseases should be sprayed in advance. It is also necessary to strengthen the management of water charges in ordinary times, so that it can be well prevented.

First of all, we need to choose some pesticides to spray on the leaves of snow peas, and we can also use root irrigation to control them, or we can turn the soil and water frequently, which can have the effect of prevention and control.

It is necessary to spray pesticides in time in the process of growth to prevent such pests and diseases, and at the same time, it is also necessary to water and fertilize in time, and also have sufficient light time.

Snow pea pole fly: I think it's better to use insecticidal pesticides directly. Because once this harmful organism is not removed, it will bring great harm to crops, so that many crops will reduce yields, or even die. Use pesticides directly.

It can effectively achieve the effect of removing pests, so as to ensure the yield of food, but it should be noted that we should also use insecticides scientifically when we use them, and we must not increase the dosage, which will not only cause damage to plants, but also cause pollution of land. The control of snow pea pole fly should not only be paid attention to, but also develop certain habits, because only in this way can we ensure the stability of grain production and will not reduce grain production due to too many pests. I think we need to do a good job in the control of snow pea pole flies in three aspects.

The first aspect is to choose crops that are resistant to diseases and pests. Because choosing such crops can effectively resist the invasion of such pests, and at the same time ensure the stability of the yield, not only can help you save economic costs, but also help you save a lot of time, compared to the frequent use of pesticides, I think it is very good. However, this kind of crop will be relatively expensive, and you must choose the best cost-effective one when choosing.

The second aspect is to carry out scientific management. There are many people who will not manage the land scientifically when they are planting, resulting in more and more serious pests and diseases when they are planting, and even lead to the situation of land extinction, so they should do scientific management of the prevention and control of such pests, only to achieve scientific and effective results, in order to ensure the stability of grain production, will not be affected by external factors and lead to a reduction in grain production.

The third aspect is to keep the surroundings andEcological balance。Because only when the ecological balance is that one's own production can increase steadily, if the land is very polluted and ecologically unbalanced, I think that even if I have more houses, the measures will not help. It is necessary to ensure the overall ecological balance and environmental safety and environmental protection in order to effectively ensure the stability of their own output.

The most effective drug is actually a drug like 560, sprayed twice a day, about a week can have a good effect, and this bean will grow very well.

It is best to use this antiseptic drug is very good, and it can achieve a very ideal effect twice a day, and it can also make the acne grow very big, and the taste is also very good.

It is better to use 1000 times the drug of phosphine for snow pea fly fly and this medicine can be very good for the control of snow pea fly

The control of snow pea pole fly is a very important method, if this problem can not be solved, then for growers, it is easy to produce some relatively large losses, so for this thing must have enough attention, then in prevention.

What kind of method should be used in the process of snow pea stem fly? I believe that many friends are also particularly concerned about this matter. <>

If you want to understand why the snow pea induction effect is very large, then you must understand why it causes injury This symptom is mainly because the larvae burrow into the perception of the scene and cause damage to the plant, in this case it will cause the neck stem to be hollow, so the transport of water and nutrients will be affected to a certain extent, then in this case, the plant will not be able to get enough nutrients, and in the end it will die, and the yield will be reduced. <>

In order to avoid such a situation, it is a very good method to control by means of pesticides, and it is also a major method used in the seedling period. <>

Through this method can get rid of the impact of these insect pests on the plant, and at the same time has a very great help effect on the lifting of materials, and in this process there are still many details that need to be paid special attention to, and can not be taken lightly when planting crops, only for these crops to have more attention, can really play a role in improving yield.

There are many farmers who do not pay special attention to these crops after planting crops, and even ignore them for a long time, so in this case, the help for the growth of crops will become relatively small, so the overall yield is not guaranteed, and this situation is believed to be undesirable.

Timely disposal of straw, drug prevention and control, etc. Timely treatment of straw to reduce overwintering of pests and diseases; Drug prevention and control, regular spraying at the seedling stage.

The way to prevent it is to sprinkle some insect repellent next to the snow peas, you can also apply more fertilizer to the snow peas when they grow in the later stage, you can also put some scarecrows next to the snow peas, you can also apply more pesticides or fertilizers when planting snow peas, or water the snow peas frequently, these are better prevention methods.

Control measures: 1. Treat straw and root stubble in time after harvesting to reduce the source of overwintering insects; 2. When small spots appear in the leaves at the initial stage, spray with 40% propyl bromidos EC 600 times, or 48% methyl chlorpyrifos EC 800 times liquid.

It can be prevented by pesticides, and the growth of snow peas should also be observed, and attention should be paid to preventing the root causes of pests and diseases, and at the same time, fertilization, control measures, and so on.

Sterilize and disinfect the seeds of snow peas in advance to prevent the emergence of some insect pests, and you can also choose seeds with better quality and fewer pests and diseases.

1.Disease. Common diseases of snow peas include blight, powdery mildew, anthracnose and blight, etc., which mainly damage the plants and leaves of snow peas.

2.Pest. The most common insect pests of snow peas are aphids, green worms, pod borers, etc., which mainly harm the stems, leaves, pods and other parts of snow peas.

When planting snow peas, we must pay attention to the development of snow peas, when it appears the following characteristics, the stem will appear brown spots at the beginning, the leaves will shrink, the color will also fade, such as the stem rot when it is serious, the plant body shrinks, generally encountered pests and diseases, must be dealt with and treated in time!

1.Methods for disease prevention and control. (1) When selecting snow peas, it is necessary to choose varieties with strong disease resistance, and excellent varieties can greatly reduce the probability of disease after snow peas are ripe.

2) Regular crop rotation and planting with other plants that are not prone to pests and diseases can also improve the disease resistance of snow peas.

3) Reasonable and appropriate amount of fertilization, more nitrogen fertilizer, less potassium fertilizer. Snow peas are fertilizer-loving crops, and more fertilization can add a lot of nutrients to it, which can improve its immunity and disease resistance.

4) Drug prevention and treatment. In the early stage of the disease, it is necessary to spray medicine to prevent and treat the disease to avoid the deterioration of the condition, which is generally applied once every ten days, and it is enough to apply it about three times.

2.For pest control. (1) When the insect pest is first discovered, the damaged dead leaves should be removed in time, so as to avoid mutual infection between leaves.

2) During the time period of winged aphid migration, it is necessary to do a good job in monitoring and control measures and timely prevention and control.

3) Pesticide control. In the early stage of larvae, it is necessary to choose the right pesticide to treat the insects in time, otherwise, the mass reproduction of insect pests will directly lead to the death of the whole snow pea plant.

Abstract In the process of planting snow peas, there are some pests and diseases due to various problems, generally speaking, there are these pests and diseases: root rot, leaf miner fly, powdery mildew, bean pod borer, aphid.

Diseases of snow peas.

In the process of growing snow peas, there are some pests and diseases due to various problems, generally speaking: root rot, leaf miner fly, powdery mildew, bean pod borer, aphids.

Insect pests include: spotted submarine fly, aphid, red spider, bean pod, whitefly diseases are: root rot, red root, powdery mildew, rust.

Pests can be treated with pesticides such as fly amine, imidacloprid, acetamiprid, Bacillus thuringiensis, chlorantraniliprole, and homochlorothiamethoxam.

After the occurrence of root rot, it is difficult to prevent it. For prevention, you can choose 40% root rot 400 times solution, or 70% methyl tobuzin wettable powder 1000 times solution, or 58% Ruifuzim wettable powder 600 times solution, or 50% carbendazim wettable powder 400 times solution, or 75% chlorothalonil wettable powder 600 times solution, or 77% killable wettable powder 600 times solution, or 64% alum wettable powder 900 times solution, any of the above pesticides plus amino acid liquid fertilizer 600 times liquid, plus fulvic acid 500 times liquid, Add 1000 times of rooting powder and spray. Spray once every 7 days, 2-3 times in a row, alternately, focusing on the base of the main stem of the plant.

If the above liquid medicine is used to irrigate the roots of the plant, the effect is better.

Brown spot is considered.

It mainly damages leaves, stems and pods. The leaves are infected with irregular lilac spots, under high temperature and high humidity conditions, the lesions spread rapidly, covering the entire leaf, and then the diseased leaves turn yellow and twist and die, some are dark brown irregular ring spots, and the necrotic place produces black spots. The pathogen mainly overwinters on the seeds and spreads through wind and rain.

Sowing too early or suffering from low temperature and cold damage, or soil clay, high humidity, or partial application of nitrogen fertilizer, and vigorous plant growth are all prone to disease.

Control methods: agricultural control. Seriously diseased fields and non-leguminous vegetables are rotated for 2-3 years, and seeds should be disinfected at the same time, pre-soaked in cold water for 4-5 hours, soaked in 50 warm water for 5 minutes, and then cooled, dried and sown.

Appropriate dense planting, increased potassium fertilizer; Pharmaceutical prevention and control. At the beginning of the disease, spray 800 times of 50 benzyl wettable powder suspension, 500 times of 70 methyl tobuzine wettable powder, and 600 times of 75 chlorothalonil wettable powder, once every 7 days, 2-3 times.
