Pesticide composition comprising thiocarbamate compound and thibenone Technical field

The present invention belongs to the field of agricultural plant protection, and more particularly to a pesticidal composition having improved properties, and more particularly to a composition comprising a thiocarbamate compound and a thiazole pesticide.

Background technique

Mancozeb is a kind of protective fungicide with high efficiency, low toxicity, low residue and wide spectrum of sterilization. It is mainly used to control various fungal diseases such as wheat, fruits and vegetables. The bactericidal mechanism can form a dense protective membrane of gas, water and light on the surface of the leaves and fruits after use, inhibiting the germination and invasion of the spores of the bacteria, and destroying the activities of various enzymes required for the normal physiological metabolism of the bacteria, thereby To achieve the purpose of sterilization and disease prevention.

Meiram is an excellent protective fungicide and a low-toxic pesticide. Because of its wide range of sterilization and resistance to resistance, the control effect is obviously superior to other similar fungicides, so the international use has always been a large tonnage product. It is currently a substitute for other protective fungicides. Most of the domestic compound fungicides are prepared by processing mancozeb, but manganese-zinc preparations cause poisoning of trace elements in crops. Black spot disease, apple spotted leaf disease, melon vegetable disease, downy mildew, field crop rust and other effects are remarkable, and no other fungicide can effectively control the occurrence of disease, and the quality is stable and reliable.

Propineb is a broad-spectrum, fast-acting protective fungicide. Suitable for crops such as tomatoes, cabbage, cucumbers, mangoes and flowers. Control cabbage downy mildew, cucumber downy mildew, tomato early and late blight, mango anthracnose. Propionate zinc is a fast-acting, long-lasting, broad-spectrum protective fungicide with good protection against downy mildew of vegetables, tobacco, hops and other crops, as well as early and late blight of tomato and potato, and Powdery mildew, rust and diseases caused by Botrytis are also inhibited. Safe for crops at recommended doses.

Pyraclostrobin is a new type of high-efficiency plant growth regulator. When it is absorbed by plants, it can promote the separation of petioles and stems and form natural shedding. It can be widely used in pesticides and fertilizers. It has strong biological activity, and its ability to induce plant cell division and callus formation is many times higher than that of general cytokinins. Improve crop absorptive capacity and increase photosynthesis, so as to increase production and enhance the purpose. It can be used in various kinds of melons, fruits, vegetables, seedlings, flowers, food, tobacco and other crops, and can also be used for tissue culture, genetic engineering, etc. Significantly improved in production Crop yield, quality improvement, low dosage, no pollution to the ecological environment, non-toxic to humans, animals, birds, bees and natural enemies.

Practical pesticide experience has shown that repeated and specific application of an active compound to control harmful strains will in many cases lead to rapid selectivity of strains, and to reduce the risk of selectivity of resistant strains, currently Mixtures of different active compounds are used to control harmful species. By combining active compounds having different mechanisms of action, resistance can be delayed, application rates can be reduced, and cost of control can be reduced.
