Technical field

The present invention relates to a kind of new applications of pesticide, and especially one kind is using prothioconazoles and cartap as main active Pesticide new opplication.

Background technique

Bakanae disease of rice is that a kind of systematicness of hazard rice infects fungal disease, is distributed widely in each rice in the world Area.At the beginning of the eighties in last century, as China's Indica changes the propulsion of round-grained rice, bakanae disease of rice hair harm aggravates year by year, and causes to have Pass department payes attention to.Carbendazim, which becomes, to be prevented and treated bakanae disease of rice first choice medicament at that time and promotes the use of a large area, and water is effectively controlled Bakanae disease of rice spreading trend.The nineties after 10 years, due to the popularization of seedling in fertile and dry seedbed seedling technology, seedbed hot and humid environment promotes The breeding of Fusarium moniliforme Sheld is infected.Meanwhile Fusarium moniliforme Sheld generates serious drug resistance to carbendazim, bakanae disease of rice roll up again it is native and Come, on Jiangsu, Shanghai and other places, outburst is caused disaster.Surrogate-data technique Prochloraz, it is strong due to having to the synthesis of hyphal cell ergosterol Inhibiting effect is recommended for bakanae disease of rice prevention and treatment, and obtains immense success.Into 21st century, transplanting is as main Rice mechanization cultivation step be widely applied, large-scale industrialized seedling due to seed soaking link in related measure and Technology is difficult to carry out in place, and Fusarium moniliforme Sheld more exacerbates bakanae disease rice vertical spread danger to the generation of Prochloraz drug resistance Evil.

Aplelenchiodes bessegi of rice is endangered as another seed-borne disease of rice, mainly pathogenic nematode piercing and sucking in rice Spike development Evil destroys panicle initiation, and it is small to show as fringe type, and grain deformity seriously affects rice yield.

Prothioconazoles are a kind of New-type wide-spectrum triazole thioketone fungicide, and the mechanism of action is inhibited in fungi before sterol Body-lanosterol or 2, the demethylation effect on 4- methylene dihydro wool steroid 14, the mechanism of action of the medicament is completely not It is same as currently preventing and treating the mode of action of bakanae disease of rice medicament.

Summary of the invention

Goal of the invention: the present invention is directed to the resistance problems that fusarium moniliforme forms related fungicide, provides one kind New prevention and treatment bakanae disease of rice and Aplelenchiodes bessegi of rice composition pesticide is reduced since bakanae disease and Aplelenchiodes bessegi of rice cause The loss of rice yield.

Technical solution: it is of the present invention it is a kind of prevent and treat rice seed-borne disease composition pesticide, containing prothioconazoles with The effective component mass ratio of cartap, the prothioconazoles and cartap is 1-400:1-500.

Preferably, above-mentioned composition pesticide contains prothioconazoles and cartap, the prothioconazoles and cartap it is effective Composition quality ratio is 1-10:1-10.

Preferably, above-mentioned composition pesticide, containing prothioconazoles and cartap, the prothioconazoles and cartap it is effective Composition quality ratio is 1-4:1.

Preferably, prothioconazoles and cartap described in above-mentioned composition pesticide and dispersing agent, emulsifier, wetting agent, filler Or one of solvent or a variety of it is made into any one dosage form allowed on pesticide.

Preferably, above-mentioned composition pesticide prothioconazoles and cartap are made into wettable powder, suspending agent, water-dispersible grain Agent, aqueous emulsion or seed treatment suspending agent.

Preferably, it is 1- that seed treatment suspending agent described in above-mentioned composition pesticide, which includes active constituent mass percent, 99%.

Preferably, the composition pesticide of above-mentioned prevention and treatment rice seed-borne disease, preferably seed treatment suspending agent and wettable Property pulvis.

The seed treatment suspending agent is composed of the following components:

Active constituent: 1-60%；

Dispersing agent: sodium lignin sulfonate, 2-15%；

Wetting agent: alkylnaphthalene sulfonate, 2-15%；

Thickener: xanthan gum, 0.1-5%；

Antifreezing agent: ethylene glycol, 0.1-5%；

Film forming agent: PVA, 2-5%；

Defoaming agent: organosilicon, 0.01-3%；

Mill base: rhodamine toner, 0.1-0.5%；

Thixotropic agent: aluminium-magnesium silicate, 0.2-5%；

Surplus is supplied with water；

The wettable powder is composed of the following components:

Active constituent: 1-60%；

Surfactant: sodium carboxymethylcellulose, 2-10%；

Wetting agent: pull open powder, 1-5%；

Filler: bentonite complements to 100%；

The active constituent is the prothioconazoles and cartap that mass ratio is 1-400:1-500.

Preferably, active constituent is the prothioconazoles and cartap that mass ratio is 1-10:1-10.

Most preferably, active constituent is the prothioconazoles and cartap that mass ratio is 1-4:1.

Preferably, the seed treatment suspending agent is prepared by following methods: each component being added to the water according to the ratio, pearl is added Grinding machine carries out continuously grinding, and seed treatment suspending agent is made.

The present invention also provides the composition pesticides of above-mentioned prevention and treatment rice seed-borne disease in prevention and treatment bakanae disease of rice and dry point Application in nematodiasis.

Preferably, the application method is to dilute composition pesticide using 500-1000 times of aqueous solution, and soak seed 24-48 Hour.

The utility model has the advantages that the seed soaking prevention and treatment bakanae disease of rice and dry point of composition pesticide of the invention for rice paddy seed Nematodiasis, reduction cause the loss of rice yield due to bakanae disease and Aplelenchiodes bessegi of rice.
