Problems solved by technology

[0005] The purpose of the present invention is to provide a bait made by adding a special compound attractant on the basis of the prior art, which can greatly improve the activity on molluscs, and also produce resistance to metaldehyde single agent The pests have high activity, and solve a series of problems such as the poor actual stomach poisoning effect of spirulina used alone, the slow speed of a single dose of metaldehyde, and resistance.

Embodiment 1

[0020] Embodiment 1: 11% tetrameric spirulina bait

[0021] The content of each component (by weight) is 10 parts of spiroxamine, 1 part of metaldehyde, 0.1 part of betaine, 15 parts of fish bone meal, and 5 parts of sucrose. After adding flour to 100 parts, it is ground into granules by a pulverizer 100-350 mesh, then mixed together into the screw mixer, stirred and mixed, quantitatively added to the kneader, after aging, quantitatively entered into the granulator, processed into bait granules, sent to the dryer, controlled drying The temperature is 40-60°C, after drying and cooling, it is packaged to obtain the finished product.

Embodiment 2

[0022] Embodiment 2: 6% tetrameric spirulina bait

[0023] The content of each component (by weight) is 3 parts of spiroxamine, 3 parts of metaldehyde, 0.5 part of thiobetaine, 1 part of fish bone meal, and 10 parts of sucrose. After adding flour to 100 parts, it is ground by a pulverizer The granules are 100-350 mesh, and then mixed into the screw mixer together, stirred and mixed, quantitatively added to the kneader, after aging, quantitatively entered into the granulator, processed into bait granules, and the granules were sent to the dryer. Control the drying temperature at 40-60°C, pack after drying and cooling to obtain the finished product.

Embodiment 3

[0024] Embodiment 3: 6% tetrameric spirulina bait

[0025] The contents of each component (by weight) are 2 parts of spiroxamine, 4 parts of metaldehyde, 0.3 part of dimethyl-beta-thiatin propionate, 5 parts of fish bone meal, 2 parts of acesulfame potassium, and 0.5 parts of allicin After adding flour to 100 parts, it is ground into granules with a size of 100-350 mesh by a pulverizer, and then mixed into a screw mixer together. For bait granules, send the granules into a dryer, control the drying temperature at 40-60°C, and pack them after drying and cooling to obtain the finished product.

Abstract

The invention discloses a mollusk killing bait formulation containing niclosamide and an application thereof. The bait formulation mainly comprises the following components in percentage by mass: 0.1%-0.3% of the niclosamide or salt thereof, 1%-95% of compound attractant and the balance of carriers, wherein the compound attractant is selected from at least two of metaldehyde, sugar, fishbone dust and a special attractant; the special attractant is selected from one or more of betaine, sulfobetaine, allicin and dimethyl-beta-dimethylpropiothetin. According to the mollusk killing bait formulation containing the niclosamide, a novel application range of the niclosamide is created; the problems that the niclosamide is not suitable for being used in vegetables of dry lands and easily generates phytotoxicity are solved; the problems that the metaldehyde easily generates pesticide residues on the surfaces of the vegetables by spraying, and the food safety problem is caused and the like are avoided; the mollusk killing bait formulation containing the niclosamide is suitable for partial exported vegetable or pollution-free vegetable planting regions and even can be used in regions with high requirements.

Description

technical field [0001] The invention relates to a molluscicidal bait containing spirulina bait and application thereof, belonging to the field of pesticides. Background technique [0002] Niclosamide, also known as niclosamide and conch, has the following structural formula (I), chemical name: N-(2'-chloro-4'-nitrobenzene)-5-chlorosalicylamide, Commonly used in agriculture is its ethanolamine salt form. Spirocidal is a kind of molluscicide that has the functions of killing and stomach poisoning. It has good quick effect and strong killing effect on snail eggs and schistosomiasis cercariae. Control harmful molluscs such as apple snails and oncomelanias. At present, spiroxamine is mainly used for spraying and soaking in paddy fields and water bodies, and it is rarely used in dry land, especially for gastric toxicity. The bait formed has a low food intake of molluscs and cannot meet the control requirements; 2, the spirulina spray is prone to various degrees of phytotoxicity...
