Embodiment 1～10

[0027] Embodiment 1~10 granules

[0028] Mix spiroucarb, active ingredient B, binder, colorant, dispersant, wetting agent, and filler uniformly in a mixing tank, extrude, granulate, dry, and sieve to obtain the present invention. For granule products, see Table 1 for details.

[0030]

[0031]

Embodiment 11～20

[0032] Embodiment 11~20 wettable powder

[0033] Mix snail, active ingredient B, dispersant, wetting agent and filler uniformly in a mixing tank, pulverize them with a jet mill and then mix them uniformly to obtain the wettable powder product of the present invention, see the table for details 2.

[0034] Table 2 Embodiment 11~20 each component and parts by weight

Embodiment 21～26

[0036] Embodiment 21~26 water dispersible granules

[0037] Spiroquab, active ingredient B, dispersant, wetting agent, disintegrating agent, filler, etc. are crushed together by air flow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain granulation material. The water-dispersible granule product of the present invention can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 3 for details.

[0040] The embodiment of the present invention adopts a method combining indoor toxicity measurement and field test. The co-toxicity coefficient (CTC) of the two agents after compounding in a certain proportion is clarified first through the indoor toxicity test. CTC120 is a synergistic effect. On this basis, field experiments were carried out.

Abstract

The invention discloses a luokuwei-containing compound gastropod-killing composition, the luokuwei-containing compound gastropod-killing composition comprises an active component A and an active component B, the active component A is selected from luokuwei, the active component B is selected from any one of the following compounds: metaldehyde, niclosamide and niclosamide ethanolamine, and the weight ratio of the active component A to the active component B is 1: 60-80:1. The luokuwei-containing compound gastropod-killing composition has a synergistic effect on a plurality of harmful gastropod damaging agricultural production, can reduce the pesticide use amount, reduce pesticide residues on crops, and reduce environmental pollution, is safe to human and livestock, and has good environment compatibility, and diseases have low tendency to produce resistance to the composition.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a compound molluscicidal composition containing snails to crop snails. Background technique [0002] The chemical name of Spirokuwei: 3-glucose (grape, arabinose, galactose, xylose)-4-methyl-4,17-dimethylol-16-hydroxy-21,22-dicarboxylate ( Acetate, angelate)-triterpene, molecular formula: C 57 h 90 o 26 , Snail Kuwei is a pure natural botanical pesticide extracted from the seeds of the Theaceae plant, which has a destructive effect on animal red blood cells, causing hemolysis and causing the death of snails. [0003] Metaldehyde chemical name: 2,4,6,8-tetramethyl-1,3,5,7-tetraoxycyclooctane (metaldehyde), molecular formula: C 8 h 16 o 4 , This product is a stomach poison, which has a certain attractant effect on apple snails. Plants do not absorb the drug, so it will not accumulate in plants. This product is moderately toxic to humans and animals. It is ...
