Abstract

The invention relates to a germicide combination which comprises thiophanate-methyl and tricyclazole, which has strong antibacterial and germicidal activity, and is applicable for the agricultural chemical protection field. The invention is mainly used for various diseases prevention and cure of the rice and has protection and cure functions to the rice, and the germicide combination is different from the prior other germicide combinations. The active ingredients of the invention are made from thiophanate-methyl and tricyclazole; the percentage of the weight distribution of the raw materials of the germicide combination is that: the thiophanate-methyl is from 20 percent to 50 percent; the tricyclazole is from 10 percent to 45 percent; the additive agent is ranged from 5 percent to 70 percent. The germicide combination can be made into wettable powder and suspension. The invention can be applicable for the various diseases prevention and cure of the rice.

Description

A kind of microbicide compositions that contains thiophanate-methyl and tricyclazole
Technical field
What the present invention relates to is a kind of microbicide compositions that contains thiophanate-methyl and tricyclazole; show extremely strong antibiotic and bactericidal activity; be applied to agricultural plant chemoproection field; be mainly used in all kinds of diseases of control paddy rice; paddy rice is had protection and therapeutic action, and this microbicide compositions is different from existing other microbicide compositions.
Background technology
Tricyclazole is a kind of agricultural production bactericide commonly used, suppress spore germination and adhere to spore to form, stop germ to be invaded and reduce the rice blast spore to produce, thus antibacterial, sterilization, but along with using in the agricultural production continuously for many years, resistance is also in continuous growth, effect is reducing, and dosage needs constantly to increase, and agriculture production cost constantly increases, controlling object is more single simultaneously, and is effective to rice blast.
Thiophanate-methyl is wide spectrum, interior absorption benzimidazole germicide, disturbs the formation of spindle in the bacterium mitosis, and then influences cell division, can be used for preventing and treating rice disease, and certain production-increasing function is arranged, but control efficiency is not obvious, and dosage is bigger.
Summary of the invention
The objective of the invention is at above-mentioned weak point, a kind of microbicide compositions that contains thiophanate-methyl and tricyclazole is provided, thiophanate-methyl and tricyclazole are composite, has obvious synergistic effect, raising is to the rice disease preventive effect, because two active ingredient bactericidal action mechanism are different, and no cross resistance, but delaying drug resistance development, enlarged the fungicidal spectrum of tricyclazole simultaneously, to rice sheath blight disease, rice diseases such as rice blast are all effective, and preventive effect is good, can prevent and treat, be better than thiophanate-methyl, two medicament lists of tricyclazole usefulness is used before the paddy rice fringe, and volume increase obviously, reduce dosage simultaneously, reduce farming originally.
A kind of microbicide compositions that contains thiophanate-methyl and tricyclazole takes following scheme to realize: a kind of microbicide compositions that contains thiophanate-methyl and tricyclazole is made up of two kinds of active ingredient thiophanate-methyls and tricyclazole, and composition fungicide prepares each accounting example of raw materials by weight and is: thiophanate-methyl 20~50%, tricyclazole 10~45%, additive 5~70%.
Additive comprises dispersant, wetting agent, antifreeze, thickener, defoamer, assistant carrier.The Synergistic bactericidal composition that contains tricyclazole and Tebuconazole is made wetting powder or suspending agent.
Dispersant in the additive adopts lignosulfonates, draws back a kind of or mixture in powder, NNO, polyoxyethylene triphenylethylene phosphenylic acid salt, alkylnaphthalene sulfonate, the alkylphenol polyoxyethylene; Wetting agent adopts alkylbenzenesulfonate; Antifreeze adopts a kind of or mixture in ethylene glycol, the propane diols; Thickener adopts a kind of or mixture in xanthans, the aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent; Assistant carrier adopts a kind of or mixture in white carbon black, precipitated calcium carbonate, kaolin, diatomite, the water.
A kind of microbicide compositions preparation technology method that contains thiophanate-methyl and tricyclazole: microbicide compositions is made wetting powder, by said ratio weighing thiophanate-methyl, tricyclazole, additive, fully mix, after airslide disintegrating mill is pulverized, mix again, through being up to the standards, promptly obtain finished product, finished product meets the every index request of country to wetting powder; Microbicide compositions is made suspending agent, by dispersant and the assistant carrier in said ratio weighing thiophanate-methyl, tricyclazole, the additive, fully mix, after the thickness sand mill evenly grinds, mix again, add thickener and antifreeze in the additive, stir again, through being up to the standards, promptly obtain finished product, finished product meets the every index request of country to suspending agent.
A kind of microbicide compositions that contains thiophanate-methyl and tricyclazole is used in preventing and treating rice disease, to rice safety, cost is low, preventive effect good.Thiophanate-methyl and tricyclazole are composite, has obvious synergistic effect, raising is to the rice disease preventive effect, because two active ingredient bactericidal action mechanism are different, no cross resistance, but delaying drug resistance development, enlarged the fungicidal spectrum of tricyclazole simultaneously, all effective to rice diseases such as rice sheath blight disease, rice blast, prove after tested, microbicide compositions chemical property of the present invention is stable, synergy is remarkable, and rice disease is had prevention and therapeutic action, shows tangible complementation and synergistic effect, can improve paddy rice fringe grain degree of saturation, improve output.
