Abstract
A synergistic composite bactericide for preventing and eliminating the diseases of apple, grape, vegetable, peanut, wheat, etc is proportionally prepared from tubeconazole, carbendazim and additive.
Description
Technical field
What the present invention had that the microbicide compositions of synergism relates to is a kind of microbicide compositions; be mainly used in melon, really, the harm of the germs of vegetables; crop had protection and therapeutic action; show extremely strong antibiotic and bactericidal activity, the said composition bactericide is different from existing other agriculture chemicals fungicides.
Background technology
As everyone knows, carbendazim, Tebuconazole all are effective bactericide, but they make separately and are used for sterilization and have its limitation.Carbendazim disturbs the fission process of germ; crop had protection and therapeutic action; to botrytis, sickle-like bacteria, wither spore bacterium, Penicillium notatum, gram pin spore bacterium, sclerotinite, black star bacterium, verticillium sp, rhizoctonia control efficiency is good for a short time, but phycomycetes, bacterium are not had preventive effect.Tebuconazole plays inhibitory action to the biosynthesis of the ergosterol of pathogen, control aecidium that can be fabulous, powdery mildew, net blotch, pine root fungus, botrytis cinerea, sigatoka bacterium, tea gall bacterium, ring spot bacterium, but to phytophthora, dry rot fungus weak effect.
Summary of the invention
The objective of the invention is at above-mentioned weak point, a kind of microbicide compositions with synergism is provided, carbendazim and Tebuconazole are composite, has obvious synergistic effect, enlarged fungicidal spectrum simultaneously, good to apple, grape, vegetables, peanut, wheat diseases control efficiency, surpass existing any other bactericide agricultural chemicals, and do not have cross resistance between the carbendazim, Tebuconazole.
Microbicide compositions with synergism takes following scheme to realize: composition fungicide active ingredient is made up of carbendazim, Tebuconazole.It is Tebuconazole 2.3～15%, carbendazim 15～28%, additive surplus that microbicide compositions prepares the raw material weight per distribution ratio.Microbicide compositions with synergism can be made into suspending agent, wetting powder.Additive adopts auxiliary agent, inserts.The suspending agent auxiliary agent adopts polyoxyethylene triphenyl phosphorus hydrochlorate, propane diols, xanthans etc., and filler adopts white carbon black, water.The wettable powder agent aid adopts dispersant calcium lignosulfonate, NNO, and neopelex, filler are potter's clay, precipitated calcium carbonate.
Microbicide compositions preparation technology method with synergism: composition suspending agent is by said ratio raw materials weighing carbendazim, Tebuconazole, additive.Additive adopts auxiliary agent and inserts.The above-mentioned raw materials that precentagewise weighs up is poured the mixing stirred tank into and is stirred, and enters the thickness sand mill and grinds, and mixes with thickener again, after the mixing stirred tank stirs, promptly can be made into the microbicide compositions finished product with synergism.Composite wettable powder is by said ratio raw materials weighing carbendazim, Tebuconazole, additive.Additive adopts auxiliary agent and inserts.The above-mentioned raw materials that precentagewise weighs up is poured into and is mixed stirred tank and stir, after airslide disintegrating mill is pulverized, mix again the composition fungicide finished product.
Microbicide compositions with synergism is used in control apple, grape, vegetables, peanut, all kinds of diseases of wheat.The composition fungicide range of application is control apple, grape, vegetables, peanut, all kinds of diseases of wheat, to crop safety, cost is low, preventive effect good.Prove that after tested combined bactericide chemical property of the present invention is stable, synergy is remarkable mutually, and controlling object is shown tangible synergy and complementary effect.
The combined bactericide advantage: 1, these two kinds of combination of active principles are used, enlarged fungicidal spectrum, control botrytis that can be fabulous, sickle-like bacteria, the various crop disease that spore bacterium, Penicillium notatum, gram pin spore bacterium, sclerotinite, black star bacterium, verticillium sp, rhizoctonia, aecidium, powdery mildew, net blotch, pine root fungus, botrytis cinerea, sigatoka bacterium, tea gall bacterium, ring spot bacterium etc. cause of withering for a short time.2, synergistic effect is remarkable, and carbendazim, Tebuconazole use the inhibition correlation coefficient (SR to the ring rot of apple bacterium separately
50) being respectively 0.98,0.99, Tebuconazole, carbendazim all have synergistic effect to be used in combination in weight percent proportioning Tebuconazole 2.3～15%, carbendazim 15～28% scopes, are used in combination the inhibition correlation coefficient (SR to the ring rot of apple bacterium
50) be 1.29～2.0.Especially with Tebuconazole 10%, carbendazim 20%, synergy is the most remarkable.3, use cost reduces, and uses the Tebuconazole cost higher separately, uses the carbendazim effect bad again separately, is used in combination preventive effect and improves, and has reduced agricultural basis again.
Embodiment:
Embodiment (is example with the suspending agent):
1, the microbicide compositions that weighing by weight percentage has synergism prepares raw material: carbendazim 28kg (weight ratio is 28%), Tebuconazole 2.3kg (weight ratio is 2.3%), additive is 69.7kg (weight ratio is 69.7%), auxiliary agent polyoxyethylene triphenyl phosphorus hydrochlorate 6kg wherein, propane diols 5kg, xanthans 4kg, the white carbon black of filler, water 54.7kg, pouring the above-mentioned raw materials that weighs up into the mixing stirred tank stirs, entering the thickness sand mill ground 1 hour, mix with thickener again, through mix stirred tank stir 1 hour evenly after, promptly make microbicide compositions finished product with synergism.
2, the microbicide compositions that weighing by weight percentage has synergism prepares raw material: carbendazim 22kg (weight ratio is 22%), Tebuconazole 8kg (weight ratio is 8%), additive is 70kg (weight ratio is 70%), auxiliary agent polyoxyethylene triphenyl phosphorus hydrochlorate 6kg wherein, propane diols 5kg, xanthans 4kg, the white carbon black of filler, water 55kg, pouring the above-mentioned raw materials that weighs up into the mixing stirred tank stirs, entering the thickness sand mill ground 1 hour, mix with thickener again, through mix stirred tank stir 1 hour evenly after, promptly make microbicide compositions finished product with synergism.
3, the microbicide compositions that weighing by weight percentage has synergism prepares raw material: carbendazim 15kg (weight ratio is 15%), Tebuconazole 15kg (weight ratio is 15%), additive is 70kg (weight ratio is 70%), auxiliary agent polyoxyethylene triphenyl phosphorus hydrochlorate 6kg wherein, propane diols 5kg, xanthans 4kg, the white carbon black of filler, water 55kg, pouring the above-mentioned raw materials that weighs up into the mixing stirred tank stirs, entering the thickness sand mill ground 1 hour, mix with thickener again, through mix stirred tank stir 1 hour evenly after, promptly make microbicide compositions finished product with synergism.
Show according to the land for growing field crops field trial: finished product of the present invention is good to preventive effects such as ring rot of apple, melon powdery mildew, earlys blight of tomato, has very high economic benefit and social benefit.
