Abstract

The invention relates to a bactericidal composition containing meptyldinocap and pyraclostrobin, of which the effective component is a binary compound of meptyldinocap and pyraclostrobin. The mass ratio of the meptyldinocap to the pyraclostrobin is (1-50):(50-1). The preparation comprises the following components in percentage by mass: 1-80% of effective component (meptyldinocap and pyraclostrobin) and the balance of allowable and acceptable auxiliary components in pesticide. The preparation formulation of the bactericidal composition can be missible oil, suspending agent, wettable powder, aqua, water-dispersible granule, aqueous emulsion, microemulsion, granule or microcapsule. The bactericidal composition is suitable for various types of powdery mildew on fruit trees, vegetables, flowers 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 pyraclostrobin. 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] Pyraclostrobin (also ...
