Root-knot nematodes, sclerotinia, powdery mildew, gray mold, early blight, etc. are the most common and most serious diseases that occur on many crops. These diseases are characterized by rapid spread, serious harm, and difficulty in eradication. In particular, root-knot nematode disease mainly damages underground roots, making its prevention and control even more difficult, causing great headaches for farmers. Today, I would like to recommend to you a very excellent fungicide-Fluopyram. You only need to dip the roots with this agent to achieve better control effects.
1. Introduction to pharmaceuticals
Fluopyram is the latest bactericidal nematicide developed by Bayer Company, with the trade names "Lufuda" and "Baibaike". It has outstanding effects in controlling root-knot nematodes, gray mold, powdery mildew, leaf mold, gray mold and other diseases. Especially in controlling root-knot nematodes, it is an efficient, low-toxic, environmentally friendly nematicide.
2. Mechanism of action
Fluopyram is a succinic acid inhibitor. Bacteria require a large amount of energy during their activities. Energy is produced by mitochondria. There are some enzymes in the inner membrane of mitochondria. This enzyme is called succinic acid active enzyme. Electron transfer needs to pass through a series of gates and be converted by these enzymes before energy can finally be generated.
Fluopyram inhibits the activity of succinate dehydrogenase on the inner membrane of mitochondria and prevents electron transfer, thereby interfering with their respiration and achieving the purpose of killing germs. After nematodes are treated with fluopyram, their bodies quickly stiffen into needle-like shapes and their activity decreases sharply. Quickly kill pests and diseases.
3. Main features
(1) Sterilize and kill insects: Fluopyram can be used to control more than 10 diseases such as powdery mildew, gray mold, leaf mold, sclerotinia, and leaf spot. It can also effectively control root-knot nematodes, which are the most difficult to control.
(2) Extremely high activity: Fluopyram is highly active. Other pesticides for controlling root-knot nematodes are calculated in kilograms, but fluopyram is calculated in milligrams. One plant only needs 0.024~0.03 ml to better control the damage of root-knot nematodes.
(3) Long lasting effect: Fluopyram has good systemic conduction properties. Fluopyram has good stability in the soil and can be continuously absorbed by the crop roots to achieve the purpose of insecticide and bactericidal. The effective period of controlling root-knot nematodes can reach more than 80 days.
(4) High efficiency and low toxicity: According to my country's pesticide toxicity classification, fluopyram is a low-toxic bactericidal and nematicide, and is currently the only fast-acting, low-toxic nematicide.
4. Applicable crops
Fluopyram can be widely used in wheat, peanuts, tomatoes, cucumbers, watermelons, melons, cabbage, grapes and other crops. However, since the drug is still within the patent protection period, the price is relatively high and the cost is obviously high. At present, it is mainly used for cash crops with high added value such as tomatoes, cucumbers, watermelons, melons, and grapes.
5. Prevention and control objects
Mainly used to control root-knot nematodes, powdery mildew, gray mold, leaf mold, sclerotinia, leaf spot, brown rot and other diseases.
6. Use technology
(1) Prevention and control of root-knot nematode disease in cucumber, watermelon, tomato, eggplant, strawberry and other crops:
When planting, dip the roots with 41.7% fluopyram suspension 1000 times before planting, or irrigate the roots with 41.7% fluopyram suspension 15000 to 20000 times, 200 ml per plant, and then cover with soil. It can effectively prevent the damage of root-knot nematodes, powdery mildew, gray mold, sclerotinia, brown rot, leaf spot and other diseases and insect pests, and the duration of effect can reach more than 80 days.
(2) To prevent and control diseases such as powdery mildew, gray mold, anthracnose, and vine blight in cucumbers, tomatoes, watermelons, strawberries, and other crops, 35% fluorobacteria·tebuconazole suspension 25-30 ml/acre can be used. Mix 30 to 40 kilograms of water and spray evenly to effectively control the occurrence and spread of the above diseases.
