First, the treatment of practical combat small formula summary!
1, tomato virus disease, said that the treatment is not so easy.
Tomato virus disease is generally more severe, and the prevention and control effect is not very obvious. The small formula is to use chlorobromoisocyanuric acid or nimbycin + zinc fertilizer, the effect will be better. Or remind to pay attention to the prevention and control of aphids and whiteflies in the early stage. Special attention should be paid to the 2,4-D operation of pollination, do not spray on the leaves and stalks, otherwise the leaves will be deformed and misdiagnosed as viral diseases.
2. Tomato leaf mold disease, the use of agents and foliar nutrition is equally important.
Tomato leaf mold is a disease that often occurs in the middle and late stages of tomatoes. Start with the lower blades. From bottom to top, easy to cause premature aging of tomatoes, the small formula is 40% fluosilazole 8000 times plus magnesium, iron 1000 times liquid Jiamei brain platinum leaf back spray, disease control and green prevention of premature aging.
3. Green pepper powdery mildew, diagnosis and prescription are very necessary.
Green pepper powdery mildew and downy mildew field diagnosis is easy to confuse, field occurrence is from the lower leaves, on the back of the green pepper leaves there is a mold layer similar to downy mildew, it is not downy mildew, is green pepper powdery mildew. The prescription is 2% chlormycin (plus rice) 200 times the most effective, remember to increase the length of 1000 times the liquid Jiamei point, otherwise, the disease is controlled, but because of the premature aging of the disease green pepper, it is not the purpose of our disease prevention.
4, tea yellow mite prevention, want to prevent and control is not so easy.
Recently, tea mites have been seriously harmful in some areas and some broad-leaved crops, and the occurrence of heavy ones include sesame, green pepper, eggplant, stevia and so on. The key to prevention and treatment must not be misdiagnosed, and it should be distinguished from viral diseases. The small formula for prevention and treatment is avermectin + azathmethine + jiamei point. Be sure to spray the back of the leaf, spray thoughtfully, as long as there is a leaf that can not hit the medicine, its reproduction speed is unexpected.
5, eggplant verticillium wilt, in the end can not be prevented.
Eggplant verticillium wilt control, prevention and treatment is very important, small formula is transplanting root prevention and see disease irrigation root pouring to see the machine to act, for the old ward, transplanting to prevent, seedlings with carbendazim + phenoxymethicazole + Jiamei dividend 1000 times liquid as a living tree watering root, pay attention to a certain inhibitory effect. Seedlings see disease with chlorine bromide + flusilazole + Jiamei dividend 1000 times the effect is better.

6, cucumber main diseases, a drug can be controlled.
The main diseases of cucumbers are low-grade fungal downy mildew and bacterial disease horn spot disease. The small formula is a kind of medicine to get it, 500 times the chlorobromoisocyanuric acid, and at most add a kind of growth-promoting jiamei point. Farmers are prompted to prevent and treat early, prevention and treatment is late, and even if the disease is stopped, it is necessary to pull the seedlings.
7. Can the diseases of cauliflower leaves and bulbs be cured in the end.
Cauliflower and broccoli have two diseases that are not very easy to treat, one is that the leaves in the middle of growth have large macula (dry, unlike downy mildew), and many drugs are used, and the effect is not good. The small formula is pyrazole + grammogen + Jiamei Brain Platinum works well. One is a bulbous disease, the ball is moldy spots, and the small formula is the large raw (daisen manganese zinc) + fluosilazole + jiamei point spray.
8, green pepper for flowers and leaves, what a ghost.
In the middle of the growth of green peppers, some fields form a whole upper leaf yellowing, yellow-green and yellow-green. Is it a virus? No, is it a deficiency of hormones? It must be, but the question is what exactly is missing? Zinc, iron, sulfur, manganese? All tried, fruitlessly. But some surprises have to surprise you. Once, when doing a fungicide test, we witnessed the miracle together, using the location of DuPont EBaotech, taking the drug on the same day, and the symptoms of green pepper disappeared the next day. Thus finally found a small formula to deal with this situation.
9, there is a commonly used small recipe called "good partner really works".
This really useful little secret recipe consists of two potions. It is chlorobromoisocyanuric acid + phenyl ether methylcyclazole + jiamei gold point. How effective it really is. Fungi, bacteria, and viruses all have good effects. What diseases can be cured? Viral diseases, blight, leaf spot disease, downy mildew, spot blight, soft rot, crop root disease, etc.
10, there is a small secret recipe for controlling the green pepper disease called "will be used".
Small secret recipes do not necessarily refer to prescriptions, and the method of use is sometimes more effective than medicine. What drugs are used to prevent and control epidemics, how many times the spray, can it be controlled? The effect is still not good. The focus of dealing with the green pepper disease is to spray the roots with the anti-epidemic agent, especially the surface of the disease center.
11, well used allicin can also play a miracle effect!
Prevention and control of soil-borne diseases, methyl frost xanthoxin + allicin + Jiamei dividend root irrigation, the effect is good. Treatment of downy mildew, blight, enoyl morpholine + allicin + jiamei point, the initial stage of the disease can quickly control downy mildew. The most obvious effect is the rapid drying of the mold layer. Treatment of blight, downy mildew hydrochloride + allicin + Jiamei dividend drizzled root irrigation, the effect is much better than with a single dose. Prevention and control of leaf spots, triazole + allicin + jiamei point, the control effect can be increased by more than 40% after mixing.
Note: When mixing with allicin, be sure to pour allicin into water, stir well, and then mix with other agents. Because the acidity of etalin is relatively large, it must be neutralized first, and then compounded.
Second, precautions for the prevention and treatment of viral diseases!
Viral diseases are different from locally infected diseases such as downy mildew and gray mold, but infect leaves, fruits and stems. Our agents are required to have good suction. And there are many ways of transmission of viral diseases, such as insect pests, field operations, seedling transmission, etc., so viral diseases are very difficult to treat, still belong to the world's plant protection problems, the following introduces some viral disease prevention precautions!
1. Pay attention to enhancing plant resistance
This is the most overlooked point, we always think that the control of diseases should be treated with drugs, but for crop virus diseases, enhancing plant resistance should be the first priority.
For example, foliar sprays of resistance-enhancing conditioners, chitin, brassica, or 1000x liquid jiamei point can significantly enhance plant resistance and prevent viral diseases.
2. Some viral diseases are easy to mix with bacterial diseases
This is also an aspect that everyone is not clear, for example, stripe virus disease is often mixed with bacterial diseases, and the effect of mixing viral agents with bacterial agents is better.

3. Pay attention to the supplementation of trace elements
For example, yellowing virus, fern leaf virus and iron zinc and other trace elements are related, timely per acre drip irrigation or flush Jiamei dividend 1 bag + Jiamei brain platinum 1 bag, foliar spray 1000 times liquid Jiamei gold point prevention effect is better.
4. Pay attention to the medication course
Viral diseases require high endoslaxibility of the drug, but the current agent is difficult to achieve this level, and we can only meet it with one medication cycle. If the incidence of viral disease is serious, it is recommended that you use the drug 3 times continuously, 5 to 7 days, and try to choose a strong systemic agent.
5, must pay attention to field operations
Viral diseases are mostly transmitted through wounds, and the spread of insect pests (whiteflies, mites, thrips, etc.) is one aspect, and field operations are an important aspect of the occurrence of greenhouse virus diseases. This is also easy for everyone to ignore, such as hanging rope, fruit picking, leaf picking, etc., must be fully aware. Sick plants can be marked and try not to manage them, or manage them at the end, or just pull them out of the shed. After the field operation, timely spray Baitai + mesophyticin + Jiamei 1000 times liquid.
6, do not plant a large number of crops around the shed that are susceptible to viral diseases
Many vegetable farmers are accustomed to planting hanging melons before and after the shed, or peppers that are prone to viral diseases, which are prone to the occurrence of viral diseases.
7. Pay attention to seize the critical period of preventing viral diseases
Practice has proved that the seedling stage and the middle period before growth are all stages where viral diseases are prone to disease, so it is necessary to prevent them in advance.
8. When pulling out the garden, pull out the plants cleanly, and do not let a large number of roots remain in the soil.
Water the soil before pulling out the garden, and then pull out the plant after two or three days, otherwise there will be a large number of roots left in the soil. Because viral diseases are systemic diseases, there may be a source of viral diseases in the root system, although viral diseases are not transmitted through soil.
