The invention discloses a sterilizing agent containing metconazole and oligosaccharide. The effective ingredients of the sterilizing agent are metconazole and oligosaccharide, the weight ratio of the metconazole to the oligosaccharide is (1:10) to (10:1). The invention further discloses application of the sterilizing agent to the prevention and curing of wheat scab. Practical tests show that the sterilizing agent provided by the invention has a remarkable effect of preventing and curing the wheat scab.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of bactericide and application thereof that contains metconazole and oligosaccharide element.
Background technology
Wheat scab has another name called reddish tone miasma, and rotten wheat head has generation in national Ge Mai district, with the middle and lower reach of Yangtze River and Northeasten Spring Wheat Area of China, occurs the heaviest.This disease main harm wheat, not only affects wheat yield and also causes that wheat seed is putrid and deteriorated, and the toxin of this disease germ secretion can also make person poultry poisoning, the general time can become in the underproduction 1-2, the time underproduction 5-6 of being very popular becomes, and even total crop failure, constitutes a serious threat to Wheat Production.
The head blight fringe portion of mainly causing harm, but can be injured in each stage of wheat growth, to infect seedling stage and cause that seedling is rotten, the middle and later periods infects and causes that bar is rotten and fringe is rotten, especially with the rotten harm maximum of fringe.General blooming stage infects, and the pustulation period shows disease, and the maturing stage causes disaster.On small ear and lepicena, there is water stain shape foxiness in the head blight initial stage of infecting, after expand to gradually whole small ear, sick small ear is withered and yellow immediately, at small ear base portion, there is the mould layer of pink colloid in the morbidity later stage.
Wheat scab has multiple fusarium infection to cause, gibberellic hypha pathogenecity is extremely strong, and distribution is extremely wide.Gibberellic hypha is got over the summer, is survived the winter on the crop residueses such as wheat or maize straw, with mycelium state, survives the winter; Spring in next year, shape ascospore, was transmitted to wheatear portion through air-flow, from wilting flower pesticide, invaded small ear; The difficulty or ease that wheat different growing is invaded germ have very big-difference, and blooming stage is the most susceptible, and take second place heading stage; Under the condition that has a large amount of bacterium source to exist, if meet 3 days above wet weather continuously between wheat heading flowering period, temperature remains on more than 15 ℃, and head blight will be very popular.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is to provide the bactericide that contains metconazole and oligosaccharide element of the good wheat scab of a kind of control efficiency.
Technical scheme: technical scheme provided by the invention is: a kind of metconazole and composite bactericide of oligosaccharide element of containing, the active ingredient of described bactericide is metconazole and oligosaccharide element, the weight ratio of described metconazole and oligosaccharide element is 1:10-10:1, described bactericidal composition also includes auxiliary agent and filler, wherein metconazole and oligosaccharide element account for the 20%-60% of bactericide gross weight, auxiliary agent accounts for the 5%-30% of bactericide gross weight, and all the other are filler.
The weight ratio of described metconazole and oligosaccharide element is 1:1-4:1.
Described bactericide formulation is a kind of in water dispersible granules, wetting powder or aqueous emulsion.
When described formulation is water dispersible granules, described auxiliary agent is one or more in lauryl sodium sulfate, ethoxylated dodecyl alcohol, lignosulfonates, sulfonic acid polyformaldehyde condensation product, polyethylene glycol, ammonium sulfate and sodium carboxymethylcellulose, and described filler is kaolin.
When described formulation is wetting powder, described auxiliary agent is lauryl sodium sulfate, sodium lignin sulfonate and pulls open one or more of powder, and described filler is diatomite.
When described formulation is aqueous emulsion, described auxiliary agent is one or more in dimethylbenzene, 1-METHYLPYRROLIDONE, alkyl benzene calcium sulfonate, phenethyl phenol mela mine-formaldehyde resin polyoxy ethyl ether, ethylene glycol, silicone compound, xanthans and aluminium-magnesium silicate, and described filler is water.
Above-mentioned a kind of contain metconazole and the application of the composite bactericide of oligosaccharide element in preventing and treating wheat scab.
Bactericide of the present invention, through actual test, has significant control efficiency to wheat scab.
Beneficial effect: compound disinfectant of the present invention is compared with conventional head blight bactericide, has the following advantages:
1, compare this kind with single dose wheat scab is had to obvious synergistic effect, can significantly improve control efficiency;
2, high poisoning microbial inoculum in can Substitute For Partial, reduces dosage, reduces the residual of environmental pollution and agricultural product;
3, can delay the pesticide resistance of wheat scab to single bactericide;
4, have advantages of that the lasting period is long, compare with single medicament, can reduce costs.
