Abstract
The invention discloses a bactericidal composition containing thifluzamide and trifloxystrobin, comprising 1-50wt% of thifluzamide, 1-50wt% of trifloxystrobin, 4-6wt% of alkylphenol polyoxyethylene phosphate ester, 0.1-0.2wt% of organosilicon, 1-2wt% of white carbon black, 4-6wt% of glycol, 0.1-0.2wt% of sodium benzoate, 0.3-5wt% of xanthan gum, 0.6-1wt% of polypropylene carboxylic acid sodium, and the balance of water. By compounding thifluzamide and trifloxystrobin, the two drug effects complement each other, the sterilization variety is enlarged, simultaneously the sterilization effect is enhanced, the application amount is low, the composition is environmentally friendly and has high prevention rate, and the cost of applying the composition is lower than that of individually using thifluzamide.
Description
Technical field
The present invention relates to a kind of bactericidal composition, relate in particular to a kind of bactericidal composition that contains thifluzamide and oxime bacterium ester.
Background technology
Thifluzamide, the full fringe of trade name, adopted name thifluzamide.Belong to the thiazole amide bactericide, have strong interior conductivity and the long lasting effect of inhaling.Thifluzamide is the succinate dehydrogenase inhibitor, because fluorine-containing, its its competitiveness in biochemical pathway is very strong, in case combine just to be difficult for recovering with substrate or enzyme.Thifluzamide all has activity to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas, especially the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc. is had special efficacy.
Oxime bacterium ester, English name Trifloxystrobin, Chinese another name: oxime grass ester; (2Z)-2-methoxyimino-2-[2-[[1-[3-(trifluoromethyl) phenyl] ethyleneimino] oxygen methyl] phenyl] methyl acetate; Trifluoro is quick; Oxime grass ester; Oxime bacterium fat; Trifluoro is quick; Former medicine content: 95%, oxime bacterium ester class wide-spectrum bactericide is one type of new fluorine-containing bactericide successfully developing as the bactericide lead compound from natural products Strobilurins.Characteristics such as having efficient, wide spectrum, protection, treat, root out, infiltration, systemic activity, resistance of rainwater washing against, lasting period are long.To 1,4-demethylation enzyme inhibitor, benzamides, the bacterial strain of dicarboxyl amine and benzimidazole generation resistance is effective, does not have cross resistance with at present existing bactericide.Nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete and Fungi Imperfecti) disease such as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc. all there is good activity.Except that powdery mildew, leaf spot are had the special efficacy, rust, downy mildew, damping off, apple apple scab there is good activity.To crop safety, because of its at soil, capable of being fast degraded in the water, so environmentally safe.
Rice sheath blight disease is the important disease in paddy rice producing region, and seedling stage to the fringe phase all can fall ill.Leaf sheath is caught an illness and is produced dirty-green water soaking mode edge blurry stigma at nearly water surface place, big ovalize of back flaring or moire shape, and the middle part is grayish green or taupe, is yellowish or canescence in the middle part of when humidity is low, the middle part disorganization shape that is translucent, the edge is dun.Several scabs of falling ill when serious merge and form big scab, are irregular moire spot, and it is withered often to cause yellow leaf.The blade scab of catching an illness also is the moire shape, and the edge takes off Huang, and scab is dirty green during rapid onset, and blade rots very soon, and the stem stalk is injured symptom like blade, and the later stage is yellowish-brown, and is easy to break.The fringe neck is injured and just is dirty green, and it is brown that the back becomes ash, the Chang Buneng heading; The not plump paddy of heading is more; Thousand kernel weight descends, and rice sheath blight disease adopts jinggangmeisu to prevent and treat for many years always, but after long-time the use; Control efficiency descends to some extent, does not appear in the newspapers as yet and adopt the bactericidal composition that contains thifluzamide and oxime bacterium ester to prevent and treat rice sheath blight disease.
Summary of the invention
The object of the present invention is to provide a kind of bactericidal composition that contains thifluzamide and oxime bacterium ester, be used to prevent and treat paddy rice, rice blast, false smut and banded sclerotial blight reduce drug cost, preserve the ecological environment.
The present invention realizes like this, is made up of following weight raw material percentage: thifluzamide 1～50%, oxime bacterium ester 1%～50%, APES phosphate 4%～6%, organosilicon 0.1%-0.2%, white carbon 1%-2%, ethylene glycol 4%-6%, Sodium Benzoate 0.1%-0.2%, xanthans 0.3%-5%, polypropylene carboxylic acid sodium 0.6%-1%; All the other are water.
The weight ratio of thifluzamide and oxime bacterium ester is preferably 50: 1 to 1: 50 in the said said composition, and more preferably 30: 1 to 1: 30, most preferably 20: 1 to 20: 1.
Technique effect of the present invention is: thifluzamide and oxime bacterium ester is together composite, and both drug effects are replenished each other, when enlarging the sterilization kind, have strengthened bactericidal effect, and usage amount is little, and is environmentally friendly, and control rate is high, and lower than using the thifluzamide cost separately.
