Abstract
The invention discloses a Saisentong-containing agricultural bactericidal composition which overcomes the defect of a single preparation. The invention discloses a composition of a bactericidal active compound. The bactericidal active compound contains Saisentong I and another any one of known bactericidal active compound II, and is mainly applied to prevention and treatment of diseases caused by plant fungi and bacteria. The composition of the bactericidal active compound has a synergetic bactericidal activity, improves the compatibility with plants, and is used for meeting the needs of agricultural production. The composition disclosed by the invention has reasonable constituents, is capable of playing the roles of treatment and protection, is good in bactericidal effect, and is capable of effectively reducing medication times and reducing medication cost; moreover, the activity and the bactericidal effect are a remarkable synergistic effect instead of simple superposition for the activities of the various constituents, the generation of resistance can be slowed down, the safety of the medicated crops is good, and the safety requirements on pesticide preparations can be met. The composition disclosed by the invention has good prevention and treatment effects on rice sheath blight, wheat sharp eyespot, false smut, rice leaf blight, bacterial stripe and the like on cereal crops.
Description
technical field [0001] The invention relates to the technical preparation field of pesticides, in particular to an agricultural fungicidal composition containing thiesin copper. Background technique [0002] We all know that plants are vulnerable to microorganisms such as bacteria, fungi, and viruses. Among them, fungal and bacterial diseases are particularly important and pose a great threat to plant growth, breeding, storage, and transportation. Active compounds for preventing and controlling such diseases include thiazole amides, triazoles, methoxyacrylates, imidazoles, etc., but in most cases, their plant tolerance and activity against plant pathogenic bacteria cannot always meet the requirements of agriculture. production needs. Therefore, it is difficult to protect plants from harmful bacteria with only one active compound. Once resistance occurs, users will be prompted to increase the dosage, which will accelerate the development of resistance, increase costs, pestic...
