Abstract

The invention relates to a bactericidal composition containing meptyldinocap and bupirimate. Active ingredients of the bactericidal composition are binary complex formulation of meptyldinocap and bupirimate. The mass ratio of meptyldinocap to bupirimate is 1-50:50-1. The active ingredients meptyldinocap and bupirimate account for 1-80 wt% of the mass of the preparation, and the balance is auxiliary components which are allowed to be used and accepted in pesticides. Dosage forms of the bactericidal composition contain missible oil, a suspending agent, a wettable powder, water dispersible granules, an emulsion in water, a micronemulsion, a particulate agent and microcapsules. The bactericidal composition is suitable for treating various powdery mildews of fruit trees, vegetables, ornamental plants such as flowers and field crops.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing medistrobin and pyrithrimol sulfonate. 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. 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] Pyrimolsulfonate belongs to pyri...
