What is the best medicine for pepper virus disease, and what is the best pesticide for pepper virus

Prevention and control methods: disease-resistant varieties are selected in production, such as Zhongjiao No. 4, Zhongjiao No. 5, Su Jiao, Red Luodan, etc. Clean the field, avoid heavy cropping, and rotate crops with onions, garlic, legumes and cruciferous vegetables for 3 to 4 years.

Use silver-gray membrane to avoid aphids and yellow plates to attract aphids. For the prevention and control of pesticides, the agents are: Poison buster, also known as virus A or 20% morpholinoguanidine hydrochloride copper wettable powder, used to prevent and control a variety of viral diseases of tomatoes, peppers and other crops, sprayed once every 7 days with 400 600 times liquid, sprayed 3 4 times in a row; spray with 15% phytopyrethox 60 120 ml with water every 667 m2, spray once every 7 days, a total of 3 4 sprays; 83 inhibitors, before and after pepper planting, spray with 600 1000 ml of 83 inhibitors every 667 m2 with water, spray once every 7 days, a total of 3 4 sprays; When aphids occur in the field, use 40% dimethoate emulsifiable concentrate 1000 times or 50% anti-aphid wettable powder 4000 times for control.

Cultivate strong seedlings, cover with mulch, plant in a timely manner, strengthen water and fertilizer management, and enhance plant disease resistance.

Greenhouse aphid trap yellow plate.

Capsicum virus disease: pepper leaves shrunken, curled, narrow and deformed, growth point atrophied, viral disease, is a virus transmitted by the mite thrips aphid. Recommendations:

For the prevention and control of altaylin or chlorfluphosphine and brassin, avermectin or pyridafen, foliar spraying once every 7 10 days, spraying 2 3 times in a row, inhibiting the reproduction of the virus, killing the virus and spreading the harmful mites of the virus, it can control the onset and prevent the spread.

The following measures should be taken to prevent and control pepper virus disease: Choose disease-resistant varieties. Seed pesticide treatment.

Soak seeds with 10% trisodium phosphate or potassium permanganate 400 times for 20 30 minutes, wash the liquid medicine on the seeds after removal, and then soak the seeds to promote germination. Timely control of aphids, whiteflies, whiteflies, leaf mites and other poison-transmitting vectors. Seedling drug prophylaxis.

Especially in the summer seedlings, spray the following agents every 10 days or so after emergence: zinc sulfate, or 500 times of mushroom proteoglycans. Field drug prophylaxis.

Spray 1000 times of alkyl alcohol copper sulfate aqueous emulsion, or 100 times of NS-83 anti-antagonist, or 200 300 times of mushroom proteoglycan, spray once every 10 days or so, and continuously control 3 4 times. When the disease occurs in the field, it can be sprayed with Ningnanmycin (fungus and poison) for prevention and control.

The first time the incidence rate of more than 10% of the medicine bottle, with 15 kg of water and the following dispensing spray, the first two times of the incidence of more than 40% of the drug each time with two bottles of medicine and the following formula spray, <>

How can we prevent and control pepper virus disease?

1.selection of disease-resistant varieties;

2.To disinfect pepper seeds and eliminate the germs carried by the seeds, you can soak the seeds with potassium permanganate solution.

3.After the pepper is planted, it is reasonably fertilized and watered, organic fertilizer is added, strong seedlings are cultivated, and its own resistance is enhanced.

4.In rainy days or when the humidity in the shed is relatively high, it is not recommended to carry out agricultural operations, such as pruning and forking leaves, to avoid infection of viral diseases in plant wounds;

5.Before planting peppers in greenhouses, insect nets should be added, and yellow boards should be hung after planting to control and eliminate aphids and planthoppers;

6.To prevent and control whiteflies and aphids in the greenhouse, acetamiprid, pymetrozine, thiamethoxam, spiromel ethyl ester and other agents can be used.

7.If a diseased plant is found, it must be uprooted as soon as possible and taken out of the shed for burial.

8.After the occurrence of capsicum virus disease, it is recommended to use lentinan polysaccharides, chitosan, amino-oligosaccharides, morpholinoguat hydrochloride, ningnanmycin, copper succin-morpholineguanidine, copper morphoguanidine, and virus A plus enylpyrazizine, to passivate the viral disease and cut off the transmission route. It can be controlled by alternating the previous agent + Bihu + amino acid foliar fertilizer, and sprayed again at an interval of 5-7 days.

At present, the drugs on the market for the prevention and treatment of viral diseases include phytoling, 32% nucleoside bromomorpholine guanidine (new formula), anti-disease carb (virus K), virus rick, virus A, virus B, virus killing, etc.

When the condition is severe, a variety of drugs should be mixed: choose 500 times of 20% virus A wettable powder, or 400 times of virus K300, or 1000 times of phytolingin emulsifiable concentrate, or 100 times of NS-83 antagonist, or 400 times of cupramia mixture mixed with zinc sulfate for prevention and control, spray once every 7 10 days, and spray 2 3 times in a row.

2. Symptoms of capsicum virus disease.

Symptoms of capsicum virus disease.

The symptoms of capsicum virus disease are complex and there are many types of manifestations, the most important of which are two types:

Macular mosaic type: dwarf diseased plants, with brown necrotic streaks on stems and branches. The leaves are dark green, light green or yellow-green mosaic mottled flower leaves, sometimes with brown necrotic spots on the veins.

Yellowing and withering type: the diseased plant is dwarfed, the leaves are greenish or yellowish-green, the top leaves of the diseased plants become smaller and narrower, and there are often necrotic plaques (yellowish patches) on the middle and lower leaves, and sometimes the diseased spots are cracked, and the diseased leaves are easy to fall off. In the later stage, the axillary buds are extracted in clusters, and the leaves are fern-shaped.

3. The causative agent of capsicum virus disease.

The causative agent of capsicum virus disease.

There are many types of viral diseases, and the macula mosaic pathogen is mainly tobacco mosaic virus, and the yellowing blight pathogen is cucumber mosaic virus.

High temperature and drought, heavy stubble, insufficient fertilizer and water, weak plant growth and easy disease. There are many aphids, and if the prevention and control is not timely, the disease is serious, and the light is too strong.

1) pesticide seed dressing: before pepper seedlings, 30% thiamethoxam seed treatment suspension can be used according to the proportion of 933 1167 ml 100 kg of seeds, or 60% imidacloprid suspension seed coating agent according to the ratio of 200 300 ml 100 kg of seeds for seed dressing, which can effectively prevent the harm of aphids, thrips, whiteflies and other pests to seedlings at the seedling stage, and the effective period can reach about 50 days.

2) Soil treatment: When planting peppers, you can choose to use 1250 grams of 1500 grams of 2% imidacloprid granules, or 1000 grams of 2% thiamethoxam granules, plus 30 50 kg of fully decomposed organic fertilizer for hole application, which can effectively prevent the harm of stinging and sucking pests such as aphids, whiteflies, thrips and other pests before pepper fruiting, and the effective period can reach about 80 days.

3) Top dressing: In the peak flowering and fruiting period of pepper, it can be combined with top dressing watering, 20% dinotefuran soluble granules can be used per mu 2000 times liquid, with drip irrigation liquid flushing, you can also use 3% dinotefuran granules 1000 1500 grams mu plus compound fertilizer 20 30 kg, mix evenly and carry out top dressing, which can effectively prevent the harm of whitefly, whitefly, thrips and other stinging and suction pests, and avoid pest poisoning. The validity period can be up to about 60 days.

Viral disease is the main virus affecting the production of pepper in China, and it occurs widely in various places. The incidence of pepper virus disease is high, the spread is fast, the yield is generally reduced by about 30%, and the serious yield is as high as more than 60%, or even extinct, and the virus disease has become the main limiting factor of pepper production.

Chemical control: In the early stage of the disease, it can be sprayed with 6000 times of water collector to improve the disease resistance of plants. The commonly used pesticides for chemical control are 500 times of 20% virus A wettable powder and 800 times of phytoling.

10 days before planting, after planting slow seedlings and at the peak fruit stage, zinc sulfate solution is sprayed once, which also has a certain disease prevention effect. The above agents should be used in turns.

Choose disease-resistant and disease-resistant varieties: such as Zhongjiao No. 2, Zhongjiao No. 5, Tianza No. 2, etc.

Seed disinfection: soak the seeds in water for 2 3 hours, then soak them in 10% trisodium phosphate solution for 20 30 minutes, wash them with water and then promote germination and sowing.

Cultivating strong seedlings: Disease-free plant collection, disease-free soil seedlings, and timely sowing. At the seedling stage, 200 400 times of aphidicide water agent should be used to control aphids in time.

Strengthen field management: Pull out diseased plants in time at the early stage of disease and destroy them outside the field. Apply enough organic fertilizer, increase phosphorus and potassium fertilizer, improve the disease resistance of the plant itself, and reduce the disease; Reasonable dense planting, mulching.

Timely water supply in the early stage, timely loosening of soil after watering, increasing ground temperature, and promoting rooting; Pay attention to ventilation in the medium term to prevent overgrowth and preserve flowers and fruits.

The special drug for viral disease of chili pepper is Olik.

According to the pathogenesis of pepper virus disease, Olik is a virus disease inhibitor developed according to the world's advanced supercritical extraction technology and the theory of external application of traditional Chinese medicine, which can achieve the best effect by inducing the activity of pepper virus, effectively destroying its virus genes, and inhibiting the replication of the virus, so as to improve the quality of pepper.

There are several ways to control the pepper virus:

1.Disease-resistant varieties were selected, such as Tianza No. 2 and Tianza No. 6. Zhongjiao 7, Zhongjiao 4, Jinjiao 3 and Xiangyan 6 were all more resistant (tolerant) varieties.

2.Peppers are sown with potassium permanganate before sowing.

Soak seeds in liquid or 10% trisodium phosphate solution for 15 20 minutes, rinse with water after removal, and promote germination and sowing.

3.When planting peppers, wash and disinfect your hands with potassium permanganate solution or 10% trisodium phosphate solution, and preferably disinfect your tools.

4.In the pruning, threshing, and fruit picking operations of peppers, hands and tools should also be rinsed with soapy water.

Capsicum virus disease is better with chlorobromoisocyanuric acid + amino-oligosaccharides.

Chlorbromoisocyanuric acid also has a very good effect on viral diseases, it will be decomposed into triazinedione and triazine in the plant body, which can effectively inhibit the reproduction of the virus, and the amino-oligosaccharides supplement nutrition and treat the virus, and the two have a good matching effect! At **, it is recommended to use 50% chlorobromoisocyanuric acid 750-1000 times spray!

Capsicum virus prevention regimen

It can be prevented with shiitake mushroom polysaccharides + zinc fertilizer + ningnanmycin! Lentinan is rich in polysaccharides such as dextran and amino acids, which can supplement nutrition and enhance immunity for chili peppers; Zinc can significantly improve the resistance of pepper plants to viral diseases. Ningnanmycin has a **plus prophylactic effect!

Precautions for the prevention and control of viral diseases

1) To prevent and control viral diseases, small insects in the field, including thrips, planthoppers, etc., must be eliminated in advance, because they are the source of infection of viral diseases!

2) For plants with severe disease, if the number is relatively small, it is recommended to pull out, and then spray the whole field with viral disease prevention and control agents. Uprooting diseased plants does not mean that there is no virus disease in the field, and it is still necessary to spray pesticides after uprooting, and we must pay attention to prevention!

3) For plots with a high incidence of viral diseases, it is recommended to spray twice continuously at an interval of 3-5 days, and it is recommended to add regulators such as brassin.

4) Plants that are overgrown with nitrogen fertilizer are most prone to viral diseases, so it is necessary to properly control the vigor of the plants!

Chlorbromide isohydrouric acid also has a very good effect on viral diseases.

It will be decomposed into triazinedione and triazine in the plant, which can effectively inhibit the reproduction of the virus, and the amino-oligosaccharides supplement nutrition and treat the virus, and the two have a good matching effect. Pepper virus disease can be said to be the most harmful disease to peppers. As long as the orange is judged to be diseased, the growth will be inhibited, the yield and quality will be damaged, and the yield will be directly extinct.

Therefore, it is recommended that all pepper growers must adhere to the strategy of preventing the virus in advance. For the idea of the configuration of the prevention program, it is recommended that you use high-nutrient ingredients + trace elements + drugs for the treatment of viral diseases. It is recommended that you use lentinan polysaccharide + zinc fertilizer + Ningnanmycin for prevention.

**Scenario

Lentinan is rich in polysaccharides such as dextran and amino acids, which can supplement nutrition and enhance immunity for chili peppers; Zinc can significantly improve the resistance of pepper plants to viral diseases, and Ningnanmycin has the best preventive effect. If it is said that a viral disease has occurred in the pepper field, then it is necessary to choose and cooperate with the targeted pesticide ingredients when using the medicine.

In addition, it still needs to be paired with high nutrients, so it works well.

Toxic fluorophos has an obvious effect on viral diseases, and it is a special ingredient that has just been listed in recent years, and 30% of toxic fluorophos is sprayed 750 times, and the effect is good. Morphoguanidine. Ketone acetate is the most effective formula for viral diseases, which is made of morpholinoguanidine hydrochloride and copper acetate, which can inhibit the synthesis of viruses.

The copper element in copper acetate can passivate the virus, and the two work well together. When using Wu Chan, it is recommended to use 60% morphoguanidine. Copper acetate 1000 times.
