Abstract

The invention relates to a bactericidal composition containing meptyldinocap and kresoxim-methyl. The active ingredients of the bactericidal composition are meptyldinocap and kresoxim-methyl in a mass ratio of (1-50) to (50-1). Meptyldinocap and kresoxim-methyl are subjected to binary compounding. The preparation comprises 1-80% by mass of meptyldinocap, 1-80% by mass of kresoxim-methyl and the balance of auxiliary ingredients which are allowed to be used and accepted in pesticides. The dosage forms of the bactericidal composition include emulsifiable concentrate, suspension concentrate, wettable powder, water aqua, water dispersible granules, emulsion in water, microemulsion, granules and microcapsules. The bactericidal composition is suitable for controlling various powdery mildew of ornamental plants such as fruit trees, vegetables, flowers and plants and the like 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 kresstrobin. 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] Kresoxim-methyl (kresoxi...
