The invention discloses a bactericidal composition for preventing and controlling soft rot of actinidia chinensis. The bactericidal composition comprises effective components including tetramycin andtebuconazole which are subjected to binary compounding and the balance of auxiliary components, wherein the mass ratio of the tetramycin to the tebuconazole ranges from (1 to 100) to (100 to 1). A preparation of the bactericidal composition is an aqueous solution, missible oil, wettable powder, granules, a suspending agent, water dispersible granules and a microcapsule. Compound bactericide takingthe tetramycin and the tebuconazole as the effective components has an obvious synergistic effect and the harmful drug resistance is delayed; the production cost and the utilization cost are reduced;the compound bactericide is mainly used for preventing and controlling diseases including the fruit soft rot, canker and leaf spot of the actinidia chinensis, and powdery mildew, botrytis cinerea, anthracnose, bacterial angular leaf spot and the like of fruits and vegetables and the like.
Description
technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal composition for preventing and treating soft rot of kiwifruit. Background technique [0002] Kiwifruit soft rot disease mainly occurs in the post-ripening stage of kiwi fruit after harvest. The pulp inside the fruit becomes soft and rots, losing its edible value. It is manifested by a small finger-sized depression in the pulp, and the epidermis of the depression is peeled off. The center of the diseased part is milky white. The surrounding is yellow-green, and the periphery is dark green in a ring shape, and the pulp is soft and rotten. Chemical control is an important means of plant disease control, and long-term, single application of a single agent can easily cause disease resistance, which indirectly leads to problems such as environmental pollution, rampant disease, high cost, and reduced crop safety. At present, there is no ideal method for the p...
