Abstract
The invention discloses a paddy rice seed soaking compound agent which can effectively prevent aphelenchoides besseyi and also can treat bakanae disease. Main ingredients of the paddy rice seed soaking agent are fosthiazate and metconazole, and the weight ratio of fosthiazate and metconazole is (120 to 1) to (1 to 500). The paddy rice seed soaking agent can effectively overcome the weaknesses that the traditional agent for preventing the aphelenchoides besseyi is limited in form, easy to degrade and unstable and can effectively prevent the paddy rice bakanae disease having fastness to carbendazim and prochloraz. The paddy rice diseased seed processing agent can be developed into high-efficiency environment-friendly forms such as missible oil, emulsion in water, suspension and the like. Seeds are processed in a soaking manner, so that precision in agent application can be realized, and the dosage of the fosthiazate per Mu can be obviously reduced.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of the rice seed soaking medicament and the application thereof that contain fosthiazate and metconazole.
Background technology
Bakanae disease of rice and Aplelenchiodes bessegi of rice are that the common two kinds of clocks of China paddy rice pass diseases.Wherein bakanae disease of rice is soaked seed owing to using Prochloraz throughout the year, causes pathogenic bacteria to produce obvious pesticide resistance and control efficiency to Prochloraz and declines.There is generation the sick countries in the world of aphelenchoides besseyi, although this disease leaf portion symptom is slight, but inhale harm panicle initiation due to nematode aphelenchoide thorn when paddy rice spikelet differentiation and cause number of grain per ear to decline, thousand kernel weight alleviates, and the repeating transmission time often causes serious harm to Rice Production.
Cartap has been applied as water prevention rice white tip medicament and has been reached more than 30 year, although also there is certain preventive effect to nematode aphelenchoide, but due to the physicochemical property that it is special, the composite processing formulation of this medicament and other medicaments is only confined to the minority formulations such as wetting powder, and easily degrade, cause control efficiency to decline obviously.
Fosthiazate is a kind of organophosphorous pesticide preventing and treating root knot nematode, and main formulation is granule, and during for preventing and treating root-knot nematode, its active ingredient mu consumption is 100-200 gram.But yet there are no any bibliographical information and practical application for preventing and treating nematode aphelenchoide.
Summary of the invention
Goal of the invention: for tradition control nematode aphelenchoide medicament cartap formulation narrow-mindedness and unstable shortcoming of easily degrading, and Fusarium moniliforme Sheld is to common fungicide---Prochloraz develops immunity to drugs present situation, the invention provides a kind of rice seed soaking compound drug, can effectively preventing nematode aphelenchoide, simultaneously doublely control bakanae disease.
Technical scheme: the invention provides a kind of rice seed soaking medicament containing fosthiazate and metconazole, its main component is fosthiazate and metconazole, and the weight ratio of fosthiazate and metconazole is 120:1 ~ 1:500.
Concrete, paddy rice seed soaking agent of the present invention can be missible oil, aqueous emulsion or suspending agent, wetting powder, dispersible all formulations of pesticide such as granula, micro-capsule suspension.The preferred missible oil of the present invention, wetting powder and aqueous emulsion.
When described seed soaking medicament is missible oil, according to the mass fraction, each component proportion is fosthiazate 0.1 ~ 3 part, metconazole 5 ~ 50 parts, and 0265 emulsifier 4.2 ~ 4.8 parts, diffusant 0.8 ~ 1 part, vegetable oil solvent adds to 25 ~ 80 parts.
When described seed soaking medicament is wetting powder, according to the mass fraction, each component proportion is fosthiazate 6 ~ 10 parts, metconazole 10 ~ 15 parts, neopelex 1.5 ~ 4.5 parts, and dispersing agent NNO 0.6 ~ 1.6 part, kaolin adds to 30 ~ 50 parts.
When described seed soaking medicament is aqueous emulsion, according to the mass fraction, each component proportion is fosthiazate 10 ~ 15 parts, metconazole 0.1 ~ 15 part, phenethyl phenol polyethenoxy ether phosphoesterase 30 .3 ~ 0.7 part, polyoxyethylene nonylphenol ether 0.2 ~ 0.7 part, propane diols 0.5 ~ 0.8 part, deionized water adds to 40 ~ 50 parts.Optimization formula as aqueous emulsion is: according to the mass fraction, and each component proportion is fosthiazate 10 parts, metconazole 10 parts, phenethyl phenol polyethenoxy ether phosphoesterase 30 .3 part, polyoxyethylene nonylphenol ether 0.2 part, propane diols 0.5 part, deionized water 29 parts.
Present invention also offers the application of above-mentioned rice seed soaking medicament.For water prevention rice white tip and bakanae disease.Every mu of consumption is that fosthiazate effectively becomes 0.1g ~ 15g, metconazole active ingredient 0.1 ~ 50g.
Beneficial effect: the shortcoming that before the present invention can effectively overcome, tradition control nematode aphelenchoide medicament cartap formulation narrow-mindedness is unstable with easily degraded, and effectively can prevent and treat bakanae disease of rice carbendazim and Prochloraz being produced to resistance.Water prevention rice seed-borne disease seed treatment can be developed to the efficient environment-friendly agent type such as missible oil, aqueous emulsion, suspending agent.And realize accuracy pesticide applying by the mode process seed of seed soaking, obviously can reduce the mu consumption of fosthiazate.
