Abstract
, can be with effectively preventing nematode aphelenchoide, while simultaneous control bakanae disease the invention discloses a kind of rice seed soaking compound drug.Its main component is fosthiazate and metconazole, and the weight ratio of fosthiazate and metconazole is 120:1~1:500.The present invention can effectively overcome tradition preventing and treating nematode aphelenchoide medicament cartap formulation narrow-mindedness and degradable unstable shortcoming in the past, and can effectively prevent and treat the bakanae disease of rice that resistance is produced to carbendazim and Prochloraz.Preventing and treating paddy rice seed-borne disease seed treatment can be developed into the efficiently environment-friendly agent type such as missible oil, aqueous emulsion, suspending agent.And handle seed by way of seed soaking and realize accuracy pesticide applying, it can obviously reduce the mu consumption of fosthiazate.
Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of rice seed soaking medicament containing fosthiazate and metconazole and
It is applied.
Background technology
Bakanae disease of rice and Aplelenchiodes bessegi of rice are that two kinds of common clocks of China paddy rice pass disease.Wherein bakanae disease of rice due to
Soaked seed throughout the year using Prochloraz, causing pathogenic bacteria, prevention effect declines to the Prochloraz generation obvious resistance to the action of a drug.LIPIDS OF DRY RICE EMBRYO point
There is generation nematodiasis countries in the world, although the disease leaf portion symptom is slight, because nematode aphelenchoide is pierced in paddy rice spikelet differentiation
Inhale harm panicle initiation and cause number of grain per ear to decline, mass of 1000 kernel mitigates, retransmit the time and often cause to seriously endanger to Rice Production.
Cartap has been applied up to more than 30 years as the sick medicament of preventing and treating aphelenchoides besseyi, although also have one to nematode aphelenchoide
Determine preventive effect, but due to its special physicochemical property, the compounding processing formulation of the medicament and other medicaments is limited only to wettable powder
The minority formulation such as agent, and easily degrade, cause prevention effect to decline obvious.
Fosthiazate is a kind of organophosphorus pesticide for preventing and treating root knot nematode, and main formulation is granule, for preventing and treating root
Its active ingredient mu consumption is 100-200 grams during tie lines worm.But it yet there are no any document report and reality for preventing and treating nematode aphelenchoide
Apply on border.
The content of the invention
Goal of the invention：For tradition preventing and treating nematode aphelenchoide medicament cartap formulation narrow-mindedness and degradable unstable lack
Point, and Fusarium moniliforme Sheld is to common fungicide --- Prochloraz develops immunity to drugs present situation, multiple the invention provides a kind of rice seed soaking
Dose out powders, can be with effectively preventing nematode aphelenchoide, while simultaneous control bakanae disease.
Technical scheme：The invention provides a kind of rice seed soaking medicament containing fosthiazate and metconazole, its main component
For fosthiazate and metconazole, the weight ratio of fosthiazate and metconazole is 120:1~1:500.
Specifically, paddy rice seed soaking agent of the present invention can for missible oil, aqueous emulsion or suspending agent, wettable powder, can
All formulations of pesticide such as dispersible granule, micro-capsule suspension.Preferably missible oil, wettable powder and aqueous emulsion of the invention.
When the seed soaking medicament is missible oil, according to the mass fraction, each group distribution ratio is 0.1~3 part of fosthiazate, metconazole 5
~50 parts, 0,265 4.2~4.8 parts of emulsifying agent, 0.8~1 part of diffusant, vegetable oil solvent adds to 25~80 parts.
When the seed soaking medicament is wettable powder, according to the mass fraction, each group distribution ratio is 6~10 parts of fosthiazate, leaf
10~15 parts of bacterium azoles, 1.5~4.5 parts of neopelex, 0.6~1.6 part of dispersing agent NNO, kaolin adds to 30~50
Part.
When the seed soaking medicament is aqueous emulsion, according to the mass fraction, each group distribution ratio is 10~15 parts of fosthiazate, metconazole
0.1~15 part, phenethyl phenol polyethenoxy ether phosphoesterase 30 .3~0.7 part, 0.2~0.7 part of NPE, the third two
0.5~0.8 part of alcohol, deionized water adds to 40~50 parts.It is as the optimization formula of aqueous emulsion：According to the mass fraction, each component
Match as 10 parts of fosthiazate, 10 parts of metconazole .3 parts of phenethyl phenol polyethenoxy ether phosphoesterase 30, NPE 0.2
Part, 0.5 part of propane diols, 29 parts of deionized water.
Present invention also offers the application of above-mentioned rice seed soaking medicament.For preventing and treating aphelenchoides besseyi disease and bakanae disease.
Every mu of consumption is fosthiazate effectively into 0.1g~15g, 0.1~50g of metconazole active ingredient.
Beneficial effect：The present invention can effectively overcome before tradition preventing and treating nematode aphelenchoide medicament cartap formulation narrow-mindedness and
Degradable unstable shortcoming, and can effectively prevent and treat the bakanae disease of rice that resistance is produced to carbendazim and Prochloraz.It will can prevent and treat
Paddy rice seed-borne disease seed treatment develops into the efficiently environment-friendly agent type such as missible oil, aqueous emulsion, suspending agent.And the side for passing through seed soaking
Formula processing seed realizes accuracy pesticide applying, can obviously reduce the mu consumption of fosthiazate.
