Abstract
The invention discloses a compound pesticide containing fosthiazate, tebuconazole and prochloraz, a preparation method and an application thereof, wherein the compound pesticide includes 1-15 parts of fosthiazate, 0.05 to 10 parts of tebuconazole and 0.5 to 2 parts of prochloraz. The compound pesticide can effectively overcome the disadvantage that the traditional insecticide cartap for preventing and treating aphelenchoides besseyi is narrow, degradable and unsteady, a treating agent for avoiding rice seed to spread disease can be developed into an emulsifiable concentrate, an emulsion in water, a suspension concentrate and a high-efficiency environmental-protection agent. The compound pesticide is compounded with tebuconazole and prochloraz to enhance fosthiazate permeability and obviously reduce fosthiazate dosage in per mu.
Description
Technical field
The invention belongs to pesticide field, especially a kind of Recompounded pesticide that contains fosthiazate, Tebuconazole and Prochloraz and its preparation method and application.
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, owing to using Prochloraz seed soaking throughout the year, causes pathogenic bacteria to produce obvious pesticide resistance to Prochloraz and control efficiency decline.
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 in paddy rice spikelet differentiation time thorn and cause number of grain per ear to decline due to nematode aphelenchoide, thousand kernel weight alleviates, and retransmits the time and often causes serious harm to Rice Production.
Cartap has been applied and has been reached more than 30 year as the sick medicament of control aphelenchoides besseyi, although nematode aphelenchoide is also had to certain preventive effect, but due to its special physicochemical property, the composite processing formulation of this medicament and other medicaments is only confined to the minority formulations such as wetting powder, and easily degraded, cause control efficiency to decline obviously.
Fosthiazate is a kind of organophosphorous pesticide of preventing and treating root knot nematode, and main formulation is granule, and its active ingredient mu consumption is 100-200 gram when preventing and treating root-knot nematode.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: provide a kind of Recompounded pesticide that contains fosthiazate, Tebuconazole and Prochloraz, the problems referred to above that exist to solve prior art.And further provide the preparation method of this Recompounded pesticide.
Technical scheme: a kind of Recompounded pesticide that contains fosthiazate, Tebuconazole and Prochloraz, contains fosthiazate 1～15 weight portion, Tebuconazole 0.05～10 weight portion, Prochloraz 0.5～2 weight portion.
In a further embodiment, described Recompounded pesticide is missible oil, aqueous emulsion or suspending agent.
The method of preparing the above-mentioned Recompounded pesticide that contains fosthiazate, Tebuconazole and Prochloraz, step is: weigh Tebuconazole, Prochloraz and fosthiazate, and add emulsifier, diffusant and vegetable oil, stir.
The method of preparing the above-mentioned Recompounded pesticide that contains fosthiazate, Tebuconazole and Prochloraz, step is: weigh Tebuconazole, Prochloraz and fosthiazate, and add emulsifier, dispersant and propane diols, supply surplus by deionized water, stir.
The application of the above-mentioned Recompounded pesticide that contains fosthiazate, Tebuconazole and Prochloraz in control aphelenchoides besseyi disease and bakanae disease.Further, fosthiazate mu consumption is 1g-15g, and every mu of consumption of Tebuconazole is that 0.05-10 gram, every mu of consumption of Prochloraz are 0.5-2 gram.
Beneficial effect: tradition control nematode aphelenchoide medicament cartap formulation narrow-mindedness and the unsettled shortcoming of easy degraded before the present invention can effectively overcome, can be developed to the efficient environment-friendly agent type such as missible oil, aqueous emulsion, suspending agent by control paddy rice seed-borne disease seed treatment.And composite by with Prochloraz and Tebuconazole, can strengthen the permeability of fosthiazate, obviously reduce the mu consumption of fosthiazate.

The composition pesticide seed soaking control aphelenchoides besseyi making with above-described embodiment and bakanae disease test.Test is processed with 25% Prochloraz missible oil and 98% cartap soluble powder medicament in contrast.Be that serious rice varieties-Huaihe River rice No. 11 occur for Aplelenchiodes bessegi of rice and bakanae disease for examination rice varieties.
25 DEG C of soaking temperatures when seed treatment, seed soaking time 48 hours, after seed soaking enough time, vernalization is to the sowing that shows money or valuables one carries unintentionally.Seedling raising method is non-irrigated seedling, after 20 days length of time rice seedlings grow, transplants land for growing field crops.Filling stage investigation bakanae disease strain rate and nematode aphelenchoide diseased plant rate also calculated preventive effect.
Result of the test shows, the embodiment of the present invention 1,2,3,4,5,6 seed soakings all have good preventive effect to paddy rice seed-borne disease Aplelenchiodes bessegi of rice and bakanae disease, embodiment 1 every mu of consumption is that 20 milliliters, embodiment 2 every mu of consumptions are 40 milliliters, embodiment 3 every mu of consumptions are 20 milliliters, embodiment 4 every mu of consumptions are 40 milliliters, embodiment 5 every mu of consumptions are 20 milliliters, and embodiment 6 every mu of consumptions are 20 milliliters.Soak seed 48 hours, reach more than 90% booting stage to Aplelenchiodes bessegi of rice preventive effect, far above cartap and 10% fosthiazate granule 120g for mu (containing 12 grams of fosthiazate active ingredients).Various embodiments of the present invention reach more than 85% the effect of bakanae disease while adopting above-mentioned consumption seed soaking, and preventive effect is higher than conventional control medicament 98% cartap soluble powder.Illustrate that sick and bakanae disease has good control efficiency to the seed treatment composition that adopts the present invention to fill a prescription to manufacture to aphelenchoides besseyi.Owing to Prochloraz being had to pesticide resistance for examination rice varieties Fusarium moniliforme Sheld, this experimental control medicament Prochloraz is to the anti-heterodyne of bakanae disease, and booting stage, preventive effect only had 50% left and right, and result is as table 1.
The preventive effect kind of the medicament of table 1, embodiment of the present invention manufacturing to aphelenchoides besseyi disease and bakanae disease: Huaihe River rice No. 11
(fosthiazate mu active constituent content is 1g-15g, and every mu of consumption of Tebuconazole scale is that 0.05-10 gram, every mu of consumption of Prochloraz scale are 0.5-2 gram.)
Table 2, Tebuconazole and Prochloraz are composite to fusarium moniliforme Tests of Synergistic Actions
As can be known from the above table, Tebuconazole and Prochloraz are composite has a good synergistic effect.
In a word, the present invention's application fosthiazate, Tebuconazole and Prochloraz are as the composite manufacture rice seed soaking of main active ingredient medicament, tradition control nematode aphelenchoide medicament cartap formulation narrow-mindedness and the unsettled shortcoming of easy degraded before can effectively overcoming, can be developed to the efficient environment-friendly agent type such as missible oil, aqueous emulsion, suspending agent by control paddy rice seed-borne disease seed treatment.And composite by with Prochloraz and Tebuconazole, can strengthen the permeability of fosthiazate, obviously reduce the mu consumption of fosthiazate, its mu of consumption is only below 20 grams, far below the consumption (100-200 gram/acre) of single dose control nematode, and can effectively administer the pesticide resistance of fusarium moniliforme to Prochloraz.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple equivalents to technical scheme of the present invention, these equivalents all belong to protection scope of the present invention.
