Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of resistance of bacteria
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Abstract

The invention belongs to the field of agricultural bactericide and particularly relates to compound bactericide containing benzo alkene triflumizole and tetraconazole. Effective ingredients of the bactericide are benzo alkene triflumizole and tetraconazole, and the weight ratio of benzo alkene triflumizole to tetraconazole is 1:(0.1-10) and preferably 1:(2-3). Bacteriocidal spectrums are expanded by means of the prepared bactericide, and the bactericide has high activity for powdery mildew of various crops; the synergistic effect is obvious and remarkable without simple combination of activity of various components; the prevention and control efficacy of the bactericide is strong, the persistent effect period is long, and resistance risks are small; the amount of effective ingredients used in a field is reduced, production and use cost is reduced, and pesticide residues and environmental pollution are reduced; the compound bactericide is composed of the effective ingredients of different action mechanisms, and therefore is beneficial for overcoming and delaying generation of germ pesticide resistance and safe to crops.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to a compound fungicide containing benzovinfluconazole and tetrafluconazole. Background technique [0002] With the promotion and extensive use of pesticides, fungicides with a single active component have a narrow range of fungicides in the control of agricultural fungicides, poor control effects, large application doses, easy to produce drug resistance and phytotoxicity, and many times of application. Many disadvantages such as aggravating environmental pollution have obviously led to a large reduction in crop production and a substantial increase in production costs. One way to control agriculturally resistant pathogens is to introduce new ingredients that are not cross-resistant with existing varieties. However, the development cost of new active ingredients is high, the development cycle is long, and the speed of resistance of bacteria can never be kept up. Other method...
