Abstract
The invention relates to a mixed bactericide for preventing and treating diseases of rice and other crops. The mixed bactericide for preventing and treating diseases of rice and other crops comprises the active ingredients of triclopyricarb and simeconazole; the ratio of triclopyricarb to simeconazole is (50:1)-(1:50), and preferably (20:1)-(1-20); besides, triclopyricarb and simeconazole have a synergistic effect; mixture of triclopyricarb and simeconazole can be prepared into agriculturally acceptable preparations by adopting the conventional pesticide processing method, and percentage by weight of the active ingredients can be 1-90%. By adopting the mixture of triclopyricarb and simeconazole, the control efficiency on diseases is improved, and the chemical cost is saved.
Description
Technical field
The present invention relates to a kind of bactericidal composition containing chlorine nalidixic bacterium ester and simeconazoles with synergistic function, belong to disinfectant use in agriculture field.
Background technology
Rice blast is distributed in national Ge Dao district, the blade of mainly causing harm, stem stalk, fringe portion.Because the period of causing harm, position difference are divided into seedling pest, leaf pest, joint pest, panicle blast, grain pest, very large on paddy growth impact, rice growth is fallen ill in earlier stage, can cause the withered of rice seedling, and heading stage, morbidity, can cause withered dead ears, had a strong impact on rice yield.To the effectively preventing method of rice blast, be chemical control, main medicament has that three rings gurgle, Isoprothiolane, carbendazim, thiophanate-methyl, rice blast peptide, Hinosan, iprobenfos, kasugarnycin etc.False smut is also that one of serious disease occurs in Rice Production in recent years.Producing at present the bactericide such as upper main application jinggangmycin, Tebuconazole, Prochloraz, carbendazim prevents and treats in medication the last week of paddy rice cut.And prevent and treat these two kinds of its most effective medicaments of disease, it not same medicament.
Chlorine nalidixic bacterium ester (test code number: SYP-7017, chemical name: N-methoxyl group-N-[2-[[(3,5,6-trichloropyridine-2-yl) oxygen] methyl] phenyl] methyl carbamate) be that China Shenyang Chemical Engineering Inst develops synthetic methoxy acrylic bactericide, its mechanism of action is to suppress the effect of germ mitochondrial respiratory.Have fungicidal spectrum wide, active high, high to non-target organism and environmental safety, the lasting period is long, the plant height feature such as safely for correspondence.Sclerotinia rot of colza, wheat powdery mildew, rice blast are all had to good control efficiency.
Flusilazole (english common name: flusilazole) belong to triazole bactericidal agent, destroy and stop the biosynthesis of ergosterol, cause cell membrane not form, make germ dead.Mainly can be used for preventing and treating Ascomycetes, Basidiomycetes and Fungi Imperfecti fungal disease, as venturia inaequalis, Powdery Mildew, the wheat class nuclear cavity bacteria of Cereal, Septoria bacterium, snag shell bacterium etc., the various pathogens on Guignardia and sweet Lay, leaf spot of peanut.Effective to disease due to sac fungi, basidiomycetes and imperfect fungus, invalid to oomycetes, pear scab is had to special efficacy.
Above active component is bactericide well known in the art, can buy by various commercial channel.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art and problem, provide a kind of rice blast, false smut and other plant disease are had to better control efficiency, and environmental friendliness, safety compound sterilizing thing.
Combination sterilization composition of the present invention be take chlorine nalidixic bacterium ester (A) as an active ingredient, and another active component is simeconazoles.
The mass ratio that in the present invention, chlorine nalidixic bacterium ester and fluosilicic gurgle is 50: 1～1: 50, preferred proportion 20: 1～10: 1.
In the present invention, the quality total amount of chlorine nalidixic bacterium ester and simeconazoles is 1%～90%, and all the other can use and acceptable auxiliary element in pesticide processing.
In the present composition except chlorine nalidixic bacterium ester and simeconazoles active component, also comprise that the auxiliary agents such as solvent, dispersant, emulsifier, stabilizing agent, antifreezing agent, wetting agent, antioxidant and other are of value to the known substance of active ingredient stable and drug effect performance in preparation, all various compositions conventional in Pesticide formulation, be not particularly limited, concrete composition and consumption can require to determine through simple experiment according to formula.
Bactericidal composition of the present invention can be processed into by known method any formulation that is applicable to agricultural use, and reasonable formulation comprises microemulsion, suspending agent, aqueous emulsion, water dispersible granules.In preparation, the quality percentage composition of active ingredient is 1%～90%.
Bactericidal composition of the present invention is used for preventing and treating paddy rice rice blast and false smut, also for the fungoid powder evil on other plant, as powdery mildew, gray mold etc.
Bactericidal composition of the present invention, can spray-on process dispenser.Also available other conventional method dispenser.
The invention has the beneficial effects as follows:
The present invention utilizes chlorine nalidixic bacterium ester and the different mechanisms of action of simeconazoles to disease fungus, has improved fungistatic effect and the control efficiency to disease of germ; Delay the generation of germ to fungicide resistance simultaneously.
Embodiment
Embodiment 1 chlorine nalidixic bacterium ester and the synergy of simeconazoles to Pyricularia oryzae: chlorine nalidixic bacterium ester of the present invention and simeconazoles are measured and carried out with reference to the agricultural industry criteria NY/T1156.2-2006 > > of the < < People's Republic of China (PRC) the toxicity of Pyricularia oryzae (Magnaporthe grisea).The former medicine of chlorine nalidixic bacterium ester and simeconazoles takes 0.1g (being converted into pure medicine) and is dissolved in 0.5ml dimethylbenzene, and adds 0.2ml Tween-20 as wetting agent, with aqua sterilisa, is dissolved to 10ml, is mixed with the mother liquor of 10000mg/L.The later sterile water solution with 0.1% Tween-20 dilutes each mother liquor and is mixed with variable concentrations series liquid.
The serial liquid of different bactericide is mixed, and its mixed ratio is in Table 1.All for test medicine and Mixed Pharmacy all the sterile water solution of 0.1% Tween-20 be diluted to the liquid of series concentration, liquid be added in proportion in the PSA medium of 50 ℃ of left and right and pour rapidly culture dish into and make pastille flat board.After cooling, in plate central authorities, move into the Pyricularia oryzae bacterium sheet (diameter 5mm) of preculture 7d.Under 27 ℃ of dark conditions, cultivate after 8d, colony diameter (colony diameter-5mm) is measured in right-angled intersection.By following formula, calculate: mycelial growth inhibition rate (%)=((contrast colony diameter-chemicals treatment colony diameter)/contrast colony diameter) * 100.Pharmacy quality concentration is changed into mass concentration logarithm (x), and mycelial growth inhibition rate changes into and suppresses probit value (y), carries out regression analysis.Calculate concentration (EC in the virulence regression equation y=bx+a of medicament, effective inhibition
50) and correlation coefficient (r) and calculate relative virus force index (ATI), theoretical toxicity index (TTI) and co-toxicity coefficient CTC), the results are shown in Table 1.
