Description
Technical field
The present invention relates to a kind of is the bactericidal composition and the application thereof of active ingredient with pyraclostrobin and tmtd, belongs to the bactericidal composition technical field of pesticide.
Background technology
Pyraclostrobin is a kind of novel methoxy acrylate (Strobilurins) class broad-spectrum germicide; have protection, treatment and good penetration, systemic action; sac fungi, basidiomycetes, oomycetes and imperfect fungus are all demonstrated significant antibacterial and bactericidal activity, be widely used in the control of fruit tree, vegetables and cereal crop disease.This bactericide belongs to the mitochondrial respiratory inhibitor, promptly blocks in the respiratory chain between cytochrome b and c1 electronics and shifts and suppress mitochondrial breathing, and the interference cell energy is supplied with, and makes cell death, thus the performance bactericidal action.Because therefore its mechanism of action uniqueness does not have mutual pesticide resistance with other common fungicides.Yet the intrinsic resistance risk of pyraclostrobin is very high, if long-term single use unavoidably can produce resistance; And this reagent cost height is bigger in each field penetration and promotion difficulty of agricultural production.By carrying out composite with other effective bactericide is to reduce production costs, and delays pesticide resistance and produces the effective way that prolongs its service life.
Tmtd (thiram) is a kind of dimethyl dithiocarbamate series bactericidal agent with protective effect.Its action principle is main to be combined with the hydrophobic bond or the metal bridge of subunit's connection on the cell membrane, causes membrane structure to be damaged, and crack, hole occur, and cell membrane loses normal physiological function.Be to destroy the somatic cells film, to many disease fungus tool activity in oomycetes, sac fungi, the Fungi Imperfecti, be usually used in seed treatment, soil treatment and leafage spraying, vegetables damping off, damping off and downy mildew of cucurbits, anthracnose etc. are all had good preventive effect, the market price is lower.
Summary of the invention
The present invention provides a kind of bactericidal composition with synergistic function and application thereof that contains pyraclostrobin and two kinds of active components of tmtd for fear of generation resistance, defect of high cost that the agent of long-term use pyraclostrobin list is brought.
The technical solution used in the present invention is as follows:
Bactericidal composition, contain active component pyraclostrobin (ovraclostrobin) and tmtd (thiram), its ratio of weight and number is 1: 40 ~ 40: 1, preferred proportion is 1: 20 ~ 20: 1, optimal proportion is 1: 8 ~ 8: 1, and the weight percentage of two kinds of active components is 1 ~ 90% in the composition, and preferred proportion is 10 ~ 70%, optimal proportion is 10 ~ 50%, the content of active component depend on each other proportioning and the degree of synergistic effect;
