Abstract
The invention relates to a synergistic sterilization composite comprising tricyclazole and tebuconazole, which shows a very strong antibacterial and germicidal activity. The invention, which has the prevention, eradication and treatment effectiveness, is applied in the agriculture rice production, which plays an very important role for the increasing yield and profit. The synergistic sterilization composite is unlike the other existing fungicide composite, in which the occurence of drug resistance can be delayed with safe use. With the incresing yield and ensured profit, the invention is easy to promote. The synergistic sterilization composite comprising tricyclazole and tebuconazole is characterized in that the fungicide composite is composed of the effective components tricyclazole and tebuconazole. The weight percentage of preparation raw materials is 20 to 70% tricyclazole, 2 to 25% tebuconazole, and 5 to 78% additive. The synergistic sterilization composite is made to wettable powder or suspension concentrate. The synergistic sterilization composite comprising tricyclazole and tebuconazole is applied in the rice diseases prevention and treatment.
Description
Technical field
What the present invention relates to is a kind of Synergistic bactericidal composition that contains tricyclazole and Tebuconazole, show the extremely strong antibiotic and bactericidal activity of rice Pyricularia grisea, have prevention, root out, therapeutic efficiency, be applied to during agricultural rice produces, increasing production of rice increased income play an important role.This Synergistic bactericidal composition is different from existing other microbicide compositions, can suspension of pesticide resistance generation, and safe in utilization, increase production without increasing the work force, be convenient to promote.
Background technology
Rice blast is to endanger severe diseases the most in the Rice Production, and whole world paddy fields nearly all has inferior disease to take place, and it is very extensive to distribute.Its extent of injury is in the popular time, general underproduction 10-20%, and serious reaches more than the 40-50%, and chemical control is the important means of control rice blast.At present; agricultural chemicals of using always on the agricultural such as Isoprothiolane, iprobenfos, kitazine, Hinosan etc. have all produced resistance; China widelys popularize the special effect agent of tricyclazole as lower-cost control rice blast; cost is low; the peasant is ready to accept, and through using for many years, also increases impact effect because of resistance; and tricyclazole is a protective fungicide, lacks result of treatment.
Tebuconazole is the wide-spectrum bactericide of developing in recent years, inhale therapeutic action in having, partially absorb and conduct by plant is vegetative to the top, suppress germ ergosterol demethylation, promote plant growth, make it well developed root system, the leaf look dark green, robust plant, effective tiller increases, thereby improves output.All effective to multiple germ, but lack the prevention protective effect, agricultural cost is also higher relatively.
Summary of the invention
The objective of the invention is at above-mentioned weak point; a kind of Synergistic bactericidal composition that contains tricyclazole and Tebuconazole is provided; active ingredient tricyclazole and Tebuconazole are used with; has tangible synergy complementation; utilize the difference of germ action site; by protection of rice plant medicament and interior suction are conducted; play the prevention protection, treat and root out germ; improve rice plant self activity; reach the increasing both production and income purpose; be better than the effect that tricyclazole, two medicament lists of Tebuconazole are used, and also effective to the bacterial strain that produces resistance, can also reduce farming this.
A kind of Synergistic bactericidal composition that contains tricyclazole and Tebuconazole takes following scheme to realize: a kind of Synergistic bactericidal composition that contains tricyclazole and Tebuconazole, it is characterized in that microbicide compositions is made up of active ingredient tricyclazole, Tebuconazole, it is tricyclazole 20～70%, Tebuconazole 2～25%, additive 5～78% that Synergistic bactericidal composition prepares raw material weight percentage.
Described 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 described 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 Synergistic bactericidal composition preparation technology method that contains tricyclazole and Tebuconazole:
1, bactericidal composition is made wetting powder, by said ratio weighing tricyclazole, Tebuconazole, additive, in the twin-screw stirred tank, fully mix, be sent to airslide disintegrating mill after the high velocity air collision is pulverized through conveyer, mix with the twin-screw stirred tank again and stirred 30 minutes, through being up to the standards, promptly obtain the big packing of finished product, finished product meets or is higher than the every index mandatory requirement of country to wetting powder.
2, bactericidal composition is made suspending agent, by dispersant, the assistant carrier in said ratio weighing tricyclazole, Tebuconazole, the additive, fully mixed 1 hour with a high-speed stirred still, after the coarse sand grinding machine evenly grinds, grind through the fine sand grinding machine more earlier, stir thickener and the antifreeze that adds down in the additive with another high-speed stirred still again, stirred again 1 hour, 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 Synergistic bactericidal composition that contains tricyclazole and Tebuconazole is used in preventing and treating rice disease.A kind of Synergistic bactericidal composition that contains tricyclazole and Tebuconazole; be different from other bactericide combinations; active ingredient tricyclazole and Tebuconazole are used with; has tangible synergy complementation; utilize the difference of germ action site; by protection of rice plant medicament and interior suction are conducted; play the prevention protection, treat and root out germ; improve rice plant self activity; reach the increasing both production and income purpose; be better than the effect that tricyclazole, two medicament lists of Tebuconazole are used, and also effective to the bacterial strain that produces resistance, can also reduce farming this.
Embodiment
Further specify the present invention below with reference to embodiment, following embodiment only is used to the present invention is described and to the present invention without limits.
Embodiment 1: for verifying that the different proportioning consumptions with Tebuconazole of tricyclazole are to the rice Pyricularia grisea fungistatic effect, carried out the Toxicity Determination of the different proportionings of tricyclazole to rice Pyricularia grisea with Tebuconazole, be made into respective concentration according to percentage by weight in the table, carry out indoor antibacterial test, now result of the test be reported as follows:
Table 1 tricyclazole and the agent of Tebuconazole list and mixture thereof are to rice blast fungus toxicity test result
