Abstract
The invention relates to the technical field of plant disease prevention and treatment and discloses a composition for preventing and treating maize sheath blight. The composition comprises, by mass, 10-20 parts of kasugamycin, 7-9 parts of bamboo vinegar liquid, 45-50 parts of mancozeb, and 8-15 parts of ethylicin. The composition is used for preventing and treating maize sheath blight, at least reduces incidence of disease by 31.7% and at most improves a corn yield by 25.2%. The composition has substantial effects of prevention and treatment on maize sheath blight.
Description
Technical field
The present invention relates to control of plant disease technical field, more specifically, relate to a kind of composition of control of maize banded sclerotial blight.
Background technology
The infringement that plant disease is fungi, bacterium or virus produce in process of growth plant, also be one of natural calamity affecting agricultural production, maize sheath blight bamboo telegraph due to the expansion of maize sown area after 20 century 70s, its main harm leaf sheath, also stem stalk can be endangered, cause fruit ear to be injured time serious, their early stage is many produces the water stain shape scab of dirty-green on base portion 1 ~ 2 stipes leaf sheath, and rear expansion is fused into irregular shape or the large scab of moire shape.Taupe in the middle part of scab, edge dark brown, spreads expansion from bottom to top, and fringe bract catches an illness and also produces same moire shape spot.Fruit ear is bald after catching an illness, and seed carefully flat or browning rots.Time serious, rhizome base portion tissue becomes canescence, secondary root yellowish-brown or rotten.Rainy, the high humidity duration, time long, sick minister went out dense white hypha body, and mycelia is gathered into multiple hypha body further, formed bulbil.
Germ survives the winter at invalid body or in soil with mycelia and sclerotium.Spring, condition adapted to, and sclerotial germination produces mycelia and invades host, and rear sick portion produces aerial hyphae, constantly expands near diseased tissues, produces and invade structure when mycelium invades corn epidermal tissue.Maize sheath blight developmenting spread is very fast, generally there is harm closely to be in China on the rise, the general incidence of disease is 70 ~ 100%, the underproduction caused is lost in 10 ~ 20%, serious in 35%, the leaf sheath of this disease hazard corn a few joint near the ground and stem stalk, cause stem foot corrupt, destroy conducting tissue, affect the conveying of moisture and nutrition.
The existing bacterial classification about control of maize banded sclerotial blight or compound in prior art, but the effect of control is undesirable.
Summary of the invention
Technical problem to be solved by this invention is the deficiency overcoming maize sheath blight control efficiency in prior art, provides a kind of composition of control of maize banded sclerotial blight.
Second object of the present invention is to provide the agricultural chemicals containing above-mentioned composition.
3rd object of the present invention is to provide above-mentioned composition or the application of agricultural chemicals in control of maize banded sclerotial blight.
Object of the present invention is achieved by the following technical programs:
A composition for control of maize banded sclerotial blight, comprises the component of following parts by weight: 10 ~ 20 parts of kasugarnycin; 7 ~ 9 parts of bamboo vinegars; 45 ~ 50 parts of maneb alkene; 8 ~ 15 parts of S-Ethyl ethylthio sulfonates.
The cause of disease of maize sheath blight is caused to be Rhizoctonia solani Kuhn, belong to Deuteromycotina fungi, germ survives the winter at invalid body or in soil with mycelia and sclerotium, the beginning of spring, condition was suitable for, sclerotial germination produces mycelia and invades host, rear sick portion produces aerial hyphae, constantly expands near diseased tissues, produces and invade structure when mycelium invades corn epidermal tissue.
Bamboo vinegar is through pyrolysis and the liquid of the characteristic smell of dark reddish brown that obtains of condensation by bamboo wood and bamboo surplus material of processing, containing Multiple components such as organic acid, phenols, ketone, aldehydes, alcohols and heterocyclic, it all has stronger inhibitory action to multiple putrefying bacteria, can be used for preventing and treating diseases and pests of agronomic crop, bamboo vinegar has the antibacterial activity of wide spectrum.
Preferably, described composition also comprises 4 ~ 10 parts of Fluoxastrobins.
Fluoxastrobin is conventional efficient germicide, and its Main Function mechanism suppresses mitochondrial respiratory, to nearly all mycota disease, as downy mildew, powdery mildew, rust, rice blast etc. all have good activity.
Preferably, above-mentioned composition comprises the component of following parts by weight: 15 ~ 20 parts of kasugarnycin; 7 ~ 9 parts of bamboo vinegars; 45 ~ 50 parts of maneb alkene; 8 ~ 10 parts of S-Ethyl ethylthio sulfonates; 4 ~ 10 parts of Fluoxastrobins.
The present invention's any one composition above-mentioned may be used to control of maize banded sclerotial blight, in above-mentioned composition, kasugarnycin, S-Ethyl ethylthio sulfonate and maneb alkene are that in prior art, report can be used for control of maize banded sclerotial blight, but the research that bamboo vinegar and Fluoxastrobin are used for control of maize banded sclerotial blight is not reported, the present invention, on the basis of existing technology in conjunction with the feature of maize sheath blight, has invented the composition of above-mentioned control of maize banded sclerotial blight Be very effective.
Comprise the agricultural chemicals of any one composition above-mentioned, the formulation of described agricultural chemicals is suspending agent, wetting powder or water dispersible granules.Particularly, according to practical application needs, can utilize preparation technique of pesticide field routine techniques that any one composition above-mentioned for the present invention is made the agricultural chemicals of corresponding formulation.
There is provided any one composition above-mentioned in the application of control of maize banded sclerotial blight kind.
There is provided any one agricultural chemicals above-mentioned in the application in control of maize banded sclerotial blight kind.
Compared with prior art, beneficial effect of the present invention:
The invention provides a kind of composition of control of maize banded sclerotial blight, applicant carries out mixture and research to various ingredients following on the basis of plant growth, make the advantage between composition significantly complementary, said composition is used for control of maize banded sclerotial blight, its incidence of disease have dropped 31.7%, the highest volume increase 25.2% of corn, composition of the present invention is used for control of maize banded sclerotial blight Be very effective.
