Abstract

The invention relates to a picoxystrobin-containing synergic bactericidal composition which comprises an active component A and an active component B, wherein the active component A is selected from picoxystrobin; the active component B is selected from triadimefon, difenoconazole, imibenconazole, myclobutanil, ipconazole, triticonazole; and the weight ratio of the active component A and B is 1%-70%:1%-50%. Wettable powder, water dispersible granules, suspensions, or emulsions can be prepared by adding additives and excipients into the active components. The composition can be used to prevent crop powdery mildew, sheath blight, downy mildew, eqpidemic diseases, scab, anthracnose, alternaria mali roberts, leaf spot, citrus scab, grape black pox, rice bakanae disease, and rice blast, is rainwater scouring resistant, and has obvious synergic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a synergistic bactericidal composition containing picoxystrobin to crop diseases. technical background [0002] Picoxystrobin, English common name: picoxystrobin, molecular formula: C 18 h 16 f 3 NO 4 , Chemical name: (E)-3-methoxy-2-[2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl]methyl acrylate. Picoxystrobin is a mitochondrial respiration inhibitor, which inhibits mitochondrial respiration through electron transfer between cytochrome b and c1. It is effective in controlling strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. [0003] Regardless of whether it is picoxystrobin, effective active ingredient B or other high-efficiency fungicides, long-term use alone will easily cause disease resistance, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not condu...
