Abstract
The invention relates to a bactericide composition for preventing and controlling cotton disease. The bactericide composition is a composition of wettable powder, suspending agent, water dispersible granule or seed coating, which is prepared from fluoride ether bacteria amide, thiram and auxiliaries of wetting agent, dispersing agent, filling agent and the like. The fluoride ether bacteria amide and the thiram are mixed by the proportion of 1:4 to 4:1 and the combination of two bactericides with different bactericidal action mechanisms not only plays an obvious synergistic effect for cotton blight, but also is helpful for postponing the drug resistance of pathogenic bacteria. The bactericidal range is wide. The bactericide composition provided by the invention is applicable to prevention and control of various fungal diseases of crops, such as cotton blight, cotton damping off, cotton anthracnose, vegetable root rot and damping off and strawberry blight.
Description
Technical field
The present invention relates to a kind of bactericide, specifically the microbicide compositions of a kind of control cotton disease (especially fusarium wilt).It is suitable for preventing and treating the multiple fungal diseases such as cotton wilt, cotton seedling blight, cotton anthracnose, vegetable root rot and damping off, strawberry fusarium wilt.
Background technology
Fluorine ether bacterium acid amides (LH-2010A), that Shandong United Pesticide Industry Co., Ltd. cooperates with Shandong Agricultural University, in the synthetic a kind of novel fluorine benzamide series bactericidal agent of innovation in 2010, chemical name: N-(the chloro-5-(trifluoromethyl of 3-) pyridine-2-methyl)-2,3,5,6-tetrafluoro-4-methoxy benzamide.It has very high biologically active to Oomycete fungi germ, has protection and therapeutic action.Fluorine ether bacterium acid amides has stronger interior absorption.Can absorb by cauline leaf, by plant bottom, to upper direction, be conducted, along plant xylem, to whole strain crop, distribute.Its structural formula is:
The organosulfureous fungicide of a kind of broad spectrum protection of tmtd (Thiram), has good control efficiency to various crop damping off, anthracnose and fusarium wilt.
Cotton is the important economic crops of China, in the whole growing process of cotton, multiple diseases usually occurs, as cotton wilt, cotton verticillium wilt, cotton seedling blight, cotton anthracnose etc.The disease of cotton is perplexing the development of cotton planting industry, particularly cotton wilt always and spread rapidly in recent years and developed for many years, and the output of cotton and quality have been caused to great impact.The medicine that has on the market at present multiple control cotton disease, have not been reported but fluorine ether bacterium acid amides and tmtd are carried out to composite control cotton disease.
Summary of the invention
The object of this invention is to provide a kind of microbicide compositions of preventing and treating cotton disease, said composition is suitable for preventing and treating the multiple fungal diseases such as cotton wilt, cotton seedling blight, cotton anthracnose, vegetable root rot and damping off, strawberry fusarium wilt, bactericidal action wide spectrum, using value is large, and economic and social benefit is very remarkable.
Technical scheme of the present invention is: a kind of microbicide compositions of preventing and treating cotton disease, it is characterized in that, and comprise active ingredient and auxiliary agent, active ingredient is fluorine ether bacterium acid amides and tmtd, and its mass ratio is 1:4 ~ 4:1, and the total content of active ingredient is 10%-60%.
The present invention can use the auxiliary agents such as wetting agent, filler, by conventional method, above-mentioned microbicide compositions is processed into suspending agent, water dispersible granules, wetting powder and seed coat agent.Wherein applying more is wetting powder.The component of described wetting powder is: fluorine ether bacterium acid amides, tmtd, filler, wetting agent and dispersant; Wherein wetting agent is lauryl sodium sulfate and pulls open powder, and dispersant is sodium lignin sulfonate, and filler is white carbon and diatomite.
The optimum ratio of above-mentioned wetting powder is (weight ratio): fluorine ether bacterium acid amides 25%, and tmtd 25%, filler white carbon 15%, filler diatomite 23%, wetting agent lauryl sodium sulfate 4%, wetting agent pulls open powder 3%, dispersant sodium lignin sulfonate 5%.
The present invention also provides a kind of method of using above-mentioned microbicide compositions control cotton wilt and various plants fungal disease.The method is in cotton's seeding time seed dressing, seed coat agent dressing, soil treatment, or when crop growth period disease just occurs, adds water and be made into suspension liquid irrigating root and use.
The invention has the beneficial effects as follows: the present invention is mixed by 1: 4～4: 1 with tmtd by fluorine ether bacterium acid amides; systemic fungicide and protectant combine; not only cotton-wilt fusarium is had to remarkable synergistic effect; also can be efficient to the multiple fungal disease on cotton, and can delay the resistance of pathogen to medicament.The present invention is suitable for preventing and treating the multiple fungal diseases such as cotton wilt, cotton seedling blight, cotton anthracnose, vegetable root rot and damping off, strawberry fusarium wilt, bactericidal action wide spectrum, and using value is large, and economic and social benefit is very remarkable.Said composition of the present invention is as shown in table 1 below to the control efficiency of cotton wilt.
Table 1 fluorine ether bacterium acid amides and tmtd composition are filled with the effect of root field control cotton wilt
* in table, data are added up through duncan's new multiple range method, containing same letter person, are that difference is not remarkable
The present invention be take fluorine ether bacterium acid amides and tmtd and when cotton growing stage disease just occurs, is prevented and treated as 50% fluorine ether bacterium acid amides wetting powder, 50% thiram wettable powder, 50% fluorine ether bacterium acid amides+tmtd (1:4) wetting powder and 50% fluorine ether bacterium acid amides+tmtd (1:1) wetting powder of active ingredient processing.Two single doses are compared with two mixed composite preparations, composition is under the working concentration of 4000 times of dilutions, the effect of field control cotton wilt is all significantly greater than the preventive effect of 1000 times of tmtd in intermixture dilutions, and higher than the preventive effect (table 1) of 4000 times of alone 50% fluorine ether bacterium acid amides wetting powders, show that fluorine ether bacterium acid amides and tmtd composition are more suitable for field control cotton wilt, and can doublely control other diseases, also can delay pathogen the resistance of fluorine ether bacterium acid amides is occurred.
Accompanying drawing explanation
