Abstract

The invention relates to a bactericidal composition containing meptyldinocap and penconazole, wherein effective components are meptyldinocap and penconazole in binary compounding. The mass ratio of meptyldinocap to penconazole is 1-50:50-1, the mass part ratio of the effective components of meptyldinocap and penconazole in the preparation is 1%-80%, and the balance is auxiliary components which are allowed and accepted in pesticides. Dose forms of the bactericidal composition comprise emulsifiable concentrates, suspending agents, wettable powders, water dispersible granules, emulsions in water, microemulsions, granules and microcapsules. The bactericidal composition is suitable for various powdery mildews of fruit trees, vegetables, flowering plants and other ornamental plants, and field crops.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal composition containing metrastrobin and penconazole. Background technique [0002] Meptyldinocap (2-isooctyl-4,6-dinitrophenyl-2-butenoate (2,4-dinitro-6-(1-methylheptyl)phenylcrotonate,2,4-DNOPC) ,CAS: 131-72-6) is a non-systemic acaricide and has a certain contact bactericidal effect. The drug was developed by Dow AgroSciences of the United States. Metrastrobin is isolated from six isomers of the fungicide (mite) dinocap (dinocap, CAS: 39300-45-3) and has the highest biological activity. One of the isomers. It is mainly used to control red spider mite and powdery mildew of apples, citrus, pears, grapes, cucumbers, melons, watermelons, pumpkins, strawberries, roses and ornamental plants. It has good control effects on mulberry tree powdery mildew and eggplant red spider mite. It has the effect of killing mite eggs. [0003] Penconazole (Penconazole...
