Root-knot nematode disease is a common disease on crops such as cucumbers and tomatoes, which is very harmful to crops. Commonly used nematicides include thiazolylphos, chlorpyrifos, carbofuran, etc., which are harmful to crops and the environment. Today, I will introduce a new drug to you. It has high activity against nematodes and is safer for people and the environment. This prescription is fluopyram. Let's learn about it together.
Characteristics of fluopyram
1. Unique mechanism of action
Fluopyram is a pyridineethylbenzamide fungicide and nematicide. It belongs to the succinate dehydrogenase inhibitor, which acts on the mitochondrial respiratory chain. By inhibiting the activity of succinate dehydrogenase, it blocks electron transfer and affects the respiration of the pathogen, resulting in the inability of the pathogen to provide the energy needs of the pathogen, thereby killing the pathogen or inhibiting its growth and development. Fluopyram can act on multiple growth stages of the pathogen and is active on spore germination, germ tube elongation, and hyphae growth.
In addition, Fluopyram also has strong nematicidal activity and can selectively inhibit nematode respiration. It is the first nematicide that inhibits complex II and represents a new type of nematicide with a new mechanism of action.
2. Control targets
Fluopyram has a wide control spectrum and can be used to control leaf spot disease, gray mold, leaf spot, powdery mildew, sclerotinia, early blight and other diseases on vegetables such as apples, grapes, pear trees, bananas, cucumbers, tomatoes and field crops. In addition, it can also control a variety of nematodes on various crops such as watermelons, cucumbers, tomatoes, tobacco, bananas, etc., and has a high nematode-killing activity.
3. Diverse modes of action
Fluopyram has protective and therapeutic effects and has strong systemic conduction activity.
4. High nematode-killing activity
Fluopyram has obvious mobility in the soil. It can be slowly and evenly distributed in the middle and upper layers of the soil, so that it can effectively and long-term protect the root system from nematode infection within the crop rhizosphere.
5. Low toxicity
Fluopyram is a low-toxic agent that can not only continuously solve the nematode problem, but also meet the requirements for environmental safety. It can be said to be the world's first low-toxic nematicide product, and has broad development prospects.
Common compound agents
1. Fluopyram·Trifloxystrobin: It is a compound of pyridineethylbenzamide fungicide fluopyram and methoxyacrylate fungicide trifloxystrobin, which has protective and certain therapeutic effects.
This product has obvious preventive effects on diseases such as cucumber, tomato, watermelon, pepper, bayberry and loquat trees, such as tomato leaf mold, cucumber powdery mildew, anthracnose, bayberry brown spot, pepper anthracnose, cucumber target spot, tomato early blight, watermelon vine blight, loquat branch blight, cucumber root knot nematode disease, etc.
2. Fluopyram·Quinco Copper: Mainly registered for the prevention and treatment of cucumber target spot disease, powdery mildew, etc. Spraying before the disease occurs or at the early stage of the disease also has a certain control effect on root-knot nematode disease and bacterial diseases. When applying the medicine, avoid drifting the liquid to other crops to prevent phytotoxicity.
3. Fluopyram·Pyrimethanil: This product is a systemic, broad-spectrum fungicide, which is a compound of pyridineethylbenzamide fungicide Fluopyram and anilinopyrimidine fungicide Pyrimethanil. It has a protective effect and a certain therapeutic effect. It has a good control effect on grape black pox, banana leaf spot, grape gray mold, citrus scab, potato early blight, strawberry gray mold, tomato gray mold, cucumber gray mold, banana black spot, eggplant gray mold, etc.
4. Fluorobacterium Tebuconazole: It has a wide spectrum of prevention and control and can be used to prevent and control various fungal diseases such as banana black spot, tomato early blight, pear brown rot, apple leaf spot, brown spot, powdery mildew, watermelon vine blight, tomato leaf mold, cucumber powdery mildew, target spot, citrus black spot, pear black spot, citrus resin disease, cucumber anthracnose, etc.
Precautions for use
1. The agent should be mixed and diluted immediately, and the prepared solution should be used immediately.
2. It should not be mixed with copper preparations and alkaline agents, otherwise the efficacy will be reduced!
3. It is toxic to aquatic organisms such as fish, bees, and silkworms. It is prohibited to use it in aquaculture areas, rivers and ponds, bee colony activity areas, crop flowering period, and silkworm room mulberry garden accessories. It is prohibited to wash the application tools in rivers and ponds.
4. Pay attention to alternating medication. When compounding with other agents, it must be prepared by the secondary dilution method and prepared immediately.
5. If you have no experience in compounding, you must conduct safety tests first.
