Chlorophos, chemical name O, O-dimethyl-(2,2,2-three chloro-1-ethoxys) phosphonate ester.Insect there are stronger stomach poison function and action of contace poison, and have permeability.Former medicine big white mouse acute oral LD
50560-630mg/kg is to the people, animal low toxicity.Can be used for preventing and treating paddy rice, tea, really, the insect pest of crop such as vegetables.
Have now found that the composite granule of carbofuran and chlorophos has the preventive effect identical with the carbofuran granule under same consumption, but toxicity reduces significantly, but and suspension of pesticide resistance generation.
Thus, the object of the present invention is to provide a kind of is carbofuran-chlorophos granular insecticide of 3% by granule weight total amount, and commodity are called 3% Kediwei, this granule high-efficiency low-toxicity.
Second purpose of the present invention is to provide the method for producing above-mentioned 3% carbofuran-chlorophos granular insecticide.
The 3rd purpose of the present invention is the application of above-mentioned 3% carbofuran-chlorophos granule as cotten aphid, corn borer, peanut nematode and sugarcane field tiger insecticide.
In order to finish task of the present invention, adopt following technical scheme.
A kind of granular insecticide, this granular insecticide are that carrier outsourcing total amount is the carbofuran and the chlorophos of 3% (by granule weight) in sand.
In the granule of the present invention the content of active ingredient carbofuran by granule weight in the scope of 0.2-2.8%, preferred 0.5-2.5%, more preferably 1.0-2.0%.
The carbofuran that is used for the present invention, granularity are more than 200 orders, and available from the Hunan Chemical Research Institute test site, trade mark is extra large sharp board.
The used chlorophos of the present invention is 90% chlorophos pulvis of our factory's production.Production method is the known technology that record is gone up by " chemical industry complete works " (the refined chief editor of plum, Chemical Industry Press).
As carrier, the preferred river of the present invention sand, other is the sand of main component with calcium carbonate, also can use.The preferred 16-50 order of the granularity of sand, % (mass ratio) 〉=95.
In order to be processed into granular pesticide by former medicine, carrier and adjuvant, when making particle, also used polyvinyl alcohol and colouring agent alkalescence crystal violet as binding agent, be insecticide as the aubergine warning colouration to distinguish and to identify granule of the present invention.The polyvinyl alcohol consumption is 0.17% of a granule weight, and alkaline crystal violet is 0.1%.
The production method of above-mentioned 3% carbofuran-chlorophos granule comprises following step successively:
(1) screening and oven dry sand;
(2) with polyvinyl alcohol: alkaline crystal violet: water=1.7: 1: the 15-17 weight ratio is mixed each material, and to neutral, heating gets painted binding agent liquid, this liquid is added in the resulting sand of step (1) and with it mix with the sour solution of transferring;
(3) add the carbofuran of 0.2%-2.8% in step (2) the gained mixture by granule weight, mixing;
(4) with chlorophos: methyl alcohol=weight ratio made the chlorophos methanol solution in 3: 1, this solution was added in step (3) the gained mixture mixing;
(5) oven dry.
Being used for the present invention's sand fineness, so select the 16-50 order, is because the carrier grains of sand are spent greatly, easily come off when sand collides as the carbofuran and the chlorophos of dressing, and during undersized, carbofuran and chlorophos is difficult for wrapping on the surface of carrier sand.Through evidence 16 orders-50 order, the sand of 〉=95% (quality) is optimal.
Water content≤0.5% of sand before the preferred dressing.This is because if the sand grains water content in the finished product when too high, in order to slough redundant moisture, is had under higher temperature or the time expand oven dry, does not only uneconomically like this, but also can cause the thermolysis of carbofuran and chlorophos.
For the water that guarantees that the active ingredient in 3% carbofuran-chlorophos granule does not reduce, must manage to remove in the technical process as much as possible to be added.Consider that carbofuran is higher than 175 ℃ in temperature and begins at once to decompose, chlorophos begins to decompose at 115 ℃, so the inventor is chosen in 65-90 ℃ of hot-air, stirs 30 rev/mins of revolutions, and drying time is under 30-50 minute the condition, to carry out baking test.Result of the test shows, the oven dry optimum condition: with 70-80 ℃ hot-air; Stirring the commentaries on classics effect is 30 rev/mins; Time is 30-45 minute.
Granular insecticide of the present invention forms owing to be that carbofuran and chlorophos are composite, so enlarged insecticidal spectrum, under the situation that preventive effect does not reduce, has significantly reduced toxicity.Again because the price of chlorophos is much lower far beyond carbofuran, so composite granule price is much lower far beyond single carbofuran granule.
Below with reference to embodiment the present invention is done more specifically, illustrates without limitation, and advantage of the present invention is done announcement more fully.Embodiment 1-produces 3% carbofuran-chlorophos granule.
Get the 16-50 order that sieves, 〉=95% (by quality) and moisture content are lower than 0.5% river sand 967.3kg, put into mixer.
In another container that can heat, add 15kg water, add 1kg alkalescence crystal violet and 1.7kg polyvinyl alcohol then successively, be heated to 50-60 ℃, get the binding agent liquid of a uniform coloring, under agitation add mixer.Add the carbofuran of 20kg then greater than 200 order fine powders, after fully stirring, add 10kg chlorophos again in the mixer and be dissolved in solution in the 3.4kg methyl alcohol, stop the agitator running after fully stirring, material in the mixture is transferred to removes moisture in the warm air drier, treating that moisture reaches is lower than at 0.8% o'clock, sends to packing, obtains finished product.Finished product expulsion rate≤5% (quality).Embodiment 2-field control effectiveness test.
