Abstract
The composite pesticide emulsion as one pesticide for preventing and killing rice borer is prepared by using triazophos and acephate as main material, emulsifier and mixed solvent as supplementary material and through mixing in certain proportion and precipitation treatment. It has high pesticidal activity, fast effect and low toxicity to human body and farm animal and can inhibit plant hopper in rice field. Its production process has no "three waste" exhausted.
Description
The present invention is one and the triazole acetyl emulsion, belongs to technical field of pesticide, especially a kind of insecticide that is used to prevent and treat the snout moth's larva of rice.
In recent years, along with the variation of tillage method, the snout moth's larva of rice be progressively ascendant trend, along with progressively stopping using of a series of high-toxic pesticides such as acephatemet, Hostathion can replace greatly.Hostathion is a kind of broad spectrum activity organic phosphor desinsection miticide, insect there be stronger tagging and stomach poison function, and can infiltrate plant tissue, nematode there is certain lethal effect, also worm's ovum is especially had tangible lethal effect to the lepidoptera pest ovum, range of application is also quite extensive, but it is reported, paddy rice is used after the Hostathion in earlier stage, to the later stage plant hopper certain negative interaction is arranged.
In order to give full play to the efficient insecticide advantage of Hostathion, overcome its weakness, the purpose of this invention is to provide a kind of to snout moth's larva of rice high-efficiency prevention and control, and act on fast, safe in utilization, to the later stage plant hopper do not have the triazole acetyl emulsion of easily accepting again of negative interaction for the peasant.
The present invention realizes like this, the triazole acetyl emulsion, still be that base stock is composite in addition with the Hostathion, it takes Hostathion, orthene, emulsifier and mixed solvent are pressed 1-50%: 1-50%: 10-40% successively: the weighing of 20-70% percentage by weight drops into fully stirs mixed mixture in the reactor, then above-mentioned gained mixture is dropped into to carry out sedimentation in the subsider and handle the branch jar packing that gets product.As mentioned above, solution of the present invention mainly is to carry out composite with orthene to Hostathion, why select orthene be composite dose of Hostathion this be all to have a good control efficiency because orthene is the same with Hostathion, though both mechanism of action are identical, but both are added with synergistic effect mutually, though and orthene belongs to low toxicity, but plant hopper there is good control efficiency, can suppress the negative interaction of Hostathion, thereby realize the purpose of the high-efficiency prevention and control snout moth's larva of rice of the present invention paddy rice later stage plant hopper stimulating growth.About the complementary synergistic effect of Hostathion and orthene, can be as follows at the experiment test form of plant protection system of Nanjing of China agriculture university referring to the present invention:
| Medicament and proportioning | Virulence regression equation | LD 50(mg/ head) | The actual measurement toxicity index | Theoretical toxicity index | Co-toxicity coefficient (CTC) |
| Hostathion (A) | Y=8.8434+1.8423X | ?0.0082 | ????100 | ????- | ?- |
| Orthene (B) | Y=7.1005+1.7645X | ?0.0645 | ????12.7 | ????- | ?- |
| ?A∶B(1∶1) | Y=9.0573+1.9926X | ?0.0092 | ????89.1 | ????56.4 | ?157.9 |
| ?A∶B(3∶2) | Y=9.4803+2.1255X | ?0.0078 | ????105.1 | ????65.1 | ?161.4 |
| ?A∶B(2∶3) | Y=7.9638+1.6578X | ?0.0163 | ????50.3 | ????47.6 | ?105.6 |
Above-mentioned form result shows, Hostathion and orthene are composite in 3: 2 ratio, co-toxicity coefficient (C.T.C) reaches 161.4, have significant synergies, character according to Hostathion and the former medicine of orthene, consider the adaptability of product simultaneously, generally select lower effective component content for use market.
Its stability of triazole acetyl emulsion of being made by such scheme has reached the GB/T1603-89 standard, and 54 ℃ (± 2 ℃) are two weeks of storage down, and outward appearance does not have significant change, keeps transparent homogeneous state.This triazole acetyl emulsion carries out toxicity test through Hunan Prov. Labour Health Occupation Disease Dispensary with big white mouse, acute oral LD50 is 121mg/kg (female) and 147mg/kg (hero) LD50) 2150mg/kg, according to its split pole standard, belong to moderate toxicity through oral examination, belong to toxicity such as low through skin test.This triazole acetyl emulsion shows through the result of the test of agriculture chemical examination institution, Hunan Province and two places, agriculture chemical examination institution, Jiangxi Province that again its control snout moth's larva of rice mu is sprayed with 75-100ml, and control efficiency is followed successively by 92.06% and 92.98% respectively.In sum, triazole acetyl emulsion of the present invention has the insecticidal activity height, and effect is fast, and is low to the person poultry toxicity, safe in utilization, can hold concurrently and prevent the characteristics of rice field later stage plant hopper, has obvious synergistic effect again, should be a kind of excellent insecticide.

Example 2: 160 kilograms of orthenes getting 210 kilograms of Hostathions that are weak yellow liquid, the crystalline solid that is white in color, that 130 kilograms of the emulsifier that Zhuzhou caustic soda factory produces, 500 kilograms of mixed solvents that Xiang River nitrogen fertilizer plant in Zhuzhou produces drop in the lump is mixed in the reactor, evenly stir and be brown with mixed liquor in the still such as last in 2 hours or brown drops into the gained mixed liquor in the subsider sedimentation then and promptly get triazole acetyl emulsion finished product equivalent more than 30 hours and divide and jar pack.
Facts have proved that triazole acetyl emulsion processing technology of the present invention is simple, raw material is easily purchased, and does not have " three wastes " discharging in the production process, environmentally safe, still a kind of product of compliance with environmental protection requirements.
