Embodiment 1

[0027] A compound pesticide preparation containing spirocarb and niclosamide ethanolammonium salt, comprising the following components by weight percentage:

[0028]

[0029] The preparation method of above-mentioned compound pesticide preparation is as follows:

[0030] Weigh 40 kg of Spirocarb, 20 kg of Niclosamide, 5 kg of Sodium Lauryl Sulfate, 12 kg of Sodium Methylene Dinaphthalene Sulfonate, and 23 kg of Tea Dry Powder. Pulverize to 300-400 mesh with a pulverizer to obtain a wettable powder containing spiricarb and niclosamide.

Embodiment 2-10

[0032] The preparation method of Examples 2-9 and Example 1 is the same as that of Example 1 except that the proportion of components is different, and the effect is equivalent to that of Example 1. The composition ratio of Examples 2-9 is shown in Table 1.

[0033] The component distribution ratio of table 1 embodiment 2-10

[0034]

[0035] Check the wettable powder prepared in Examples 1-9, wherein the active ingredient content is ≥ 11.0%, moisture ≤ 2.0%, pH value 8.5-10.5, sieving rate (through a 50 μm sieve) ≥ 95%, suspension rate ≥ 90%, Long-lasting foaming (1min) ≤ 10mL, wettability ≤ 1min, qualified for accelerated heat storage stability.

[0036] Among embodiments 1-9, sodium lauryl sulfate can be sodium dodecylbenzene sulfonate, alkyl succinic acid sulfonate (such as alkyl succinic acid sodium sulfonate), alkylnaphthalene sodium sulfonate or fatty alcohol Instead of polyoxyethylene ether, sodium methylene dinaphthalene sulfonate can be replaced by sodium lignos...

Embodiment 10

[0051] The wettable powder containing spiricarb and niclosamide ethanolammonium salt prepared in Example 1 below is an example to do the test of killing oncomelania, to the purposes of the compound pesticide preparation containing spiricarb and niclosamide ethanolammonium salt Explain in detail.

[0052] Test unit: Hubei Institute of Schistosomiasis Control

[0053] Test time: June 2014

[0054] Test agent: Group A, the wettable powder containing spiricarb and niclosamide ethanolammonium salt obtained in Example 1.

[0055] Group B, 50% niclosamide ethanolammonium wettable powder (WPN).

[0056] Group C: 4% Luowei powder (developed by Hubei Jinhaichao Technology Co., Ltd.).

[0057] Group D, clear water.

[0058] Test plan:

[0059] In Dayuan Town, Jianli County, Hubei Province, a ditch and a river beach were selected, and the concentration of 2.5g / m 3 , 5.0g / m 2 Prepared in Example 1 2 Molluscicide test of wettable powder solution by dipping method and spraying method...

Abstract

The invention discloses a compound pesticide preparation containing thiamine disulfide and niclosamide ethanolamine and application thereof. The pesticide preparation comprises the following components in percentage by weight: 20-50 percent of a thiamine disulfide parent drug or a preparation containing the thiamine disulfide, 10-30 percent of niclosamide ethanolamine and the balance of aids. A preparation method comprises the following steps: weighing all components according to the mass ratio; mixing all the components; grinding the components until the mesh is 300-400 after the components are uniformly stirred. The pesticide preparation has a reasonable formula and is low in cost, convenient to use and good in oncomelania killing effect. The preparation method is simple, the process flow is extremely simple, the operation is extremely simple, and therefore the preparation cost is quite low. The pesticide preparation can kill oncomelania and is good in oncomelania killing effect. The killing rate of the oncomelania exceeds 81 percent seven days after spraying of a pesticide, and the oncomelania is unlikely to be resistant to drugs.

Description

technical field [0001] The present invention relates to the technical field of pesticides, more specifically to a compound pesticide preparation containing spirocarb and niclosamide ethanolammonium salt, and also to a compound pesticide preparation containing spirocarb and niclosamide ethanolammonium salt Use in medicines for killing snails. Background technique [0002] Schistosoma, also known as schistosoma, is a flat-shaped animal that parasitizes in the veins of the host, parasitizes most vertebrates, and is mainly distributed in 76 countries and regions in Asia, Africa, and Latin America. The eggs of Schistosoma japonicum enter the bladder through the vein wall and are excreted with urine. The larva enters the snail and develops in the intermediate host snail (mainly Bulinus and Physopsis). The mature larva enters the final host human body through the skin or mouth, harming the human body . Schistosomiasis is the most important parasitic disease that endangers people'...
