Problems solved by technology

[0004] After searching, the applicant found that there is currently no literature report on the mixing of fluflufenad and iprodione to prevent and treat powdery mildew. Further tests have found that the compounding of fluflufenad and iprodione, which have different mechanisms of action, has an unexpected effect. Not only the synergistic effect is significant, but also can significantly improve the control effect of brown spot, spotted leaf disease, powdery mildew, reduce the amount of medicine, reduce the cost of control, and improve the safety of crops.

Abstract

The invention discloses a bactericidal composition containing cyflufenamid and iprodione and application of the bactericidal composition. The bactericidal composition is prepared from effective active ingredients consisting of a first active ingredient, that is, cyflufenamid and a second active ingredient, that is, iprodione, wherein the weight ratio of the first active ingredient to the second active ingredient is (1 to 50) to (50 to1), preferably (1 to 30) to (30 to 1), and further preferably (1 to 10) to (10 to 1). The composition can be prepared into an agriculturally-allowable suspending agent, a microemulsion, a water emulsion, a water aqua, a dispersible oil suspending agent, wettable powder and a water dispersing granule. The bactericidal composition disclosed by the invention has reasonable components and good bactericidal effects. In addition, the activity and the bactericidal effect of the bactericidal composition are not simple superposition of the activities of all the components. Compared with an existing single preparation, the bactericidal composition has the advantages of remarkable bactericidal effect, remarkable synergistic effect and high safety to crops. The bactericidal composition disclosed by the invention has a remarkable preventing and controlling effect on brown spot, alternaria leaf spot and powdery mildew of the crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of the first active ingredient cycloflufenamide, the second active ingredient iprodione and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Cyflufenamide, English name cyflufenamid, chemical name: (Z)-N-[α-(cyclopropylmethoxyimino)-2,3-difluoro-6-(trifluoromethyl)benzyl]-2 -Phenylacetamide is an amide fungicide developed by Nippon Soda Corporation for the prevention and treatment of powdery mildew in various crops. The mechanism of action of iprodione is that it can effectively inhibit the formation and growth of haustoria on the mycelium of powdery mildew, the growth of secondary mycelium and the formation of conidia. It is not a sterol, phospholipid, chitin and protein synthesis inhibitor, does not affect mitochondrial respiration and cell membrane function. It has excellent protective and therapeutic effects, long-lasti...
