Embodiment 1

[0031] Embodiment 1: the preparation method of granules of the present invention (technical scheme one):

[0032] Based on the total weight of granules, including: emamectin 1%, diazinon 1%, quartz sand 75%, corn starch 1%, polyvinyl alcohol 0.1%, attapulgite 0.5%, polyvinylpyrrolidone 0.2 %, the rest is a mixture of calcium bicarbonate and white kaolin.

[0033] Such as figure 1 As shown, according to the production process diagram of the granules of the present invention, 2% emamectin·diazinon granules are obtained.

Embodiment 2

[0034] Embodiment 2: the preparation method of granules of the present invention (technical scheme two):

[0035] Based on the total weight of the granules, it includes: 10% to 50% of carrier fertilizer, 1% of sweet potato starch, 0.2% of gum arabic, 0.2% of industrial gelatin, 0.5% of polyvinyl alcohol, and the rest is a mixture of calcium bicarbonate and white kaolin.

[0036] Such as figure 2 As shown, according to the production process diagram of the granules of the present invention, the 0.1% emamectin·diazinon granules are obtained.

[0037] The production process of the granule preparation method of the present invention is mature, and can produce products with qualified quality and stable effect according to product standards. In order to verify the stability of product quality, we conducted a thermal storage stability test of the product: store it at 54°C±2°C for 14 days, and measure the decomposition rate, moisture, pH value, etc. of the active ingredients. The t...

Embodiment 3

[0038] Embodiment 3: In order to better verify the actual application effect of the present invention, the field efficacy test of the granule of the present invention is illustrated below with examples.

[0039] Drugs for testing:

[0040] (1) Test agent: 0.1% emamectin · diazinon fertilizer granules (0.05% emamectin: 0.05% diazinon); 2% emamectin · diazines Phosphorus granules (1% emamectin: 1% diazinon);

[0041] (2) Control agents: 1% emamectin microemulsion, 5% diazinon granules.

[0042] (3) Control object: Cucumber root-knot nematode

[0043] (4) Application method: spraying, the control agent 1% emamectin microemulsion mixed with water for root irrigation, and 5% diazinon granule mixed with fine soil for spreading.

[0044] On September 11, 2013, a field efficacy test of emamectin and diazinon granules for controlling cucumber root-knot nematode was carried out in Yacheng Town, Sanya City, Hainan Province.

[0045] Table 2. Field efficacy test results of emamectin and...

Abstract

The invention discloses methylaminoavermectin-diazinon particles. The methylaminoavermectin-diazinon particles comprise methylaminoavermectin and diazinon as effective components and pesticide auxiliary agents, wherein a mass part ratio of methylaminoavermectin to diazinon is in a range of 1: 20 to 20: 1 and a ratio of methylaminoavermectin and diazinon in the methylaminoavermectin-diazinon particle is in a range of 0.01-20wt%. The methylaminoavermectin-diazinon particles are suitable for preventing and controlling root-knot nematode on crops such as vegetables, peanuts, watermelons and bananas. The methylaminoavermectin-diazinon particles effectively, scientifically and reasonably utilize resources, reduce pesticide-caused environmental pollution, have a low cost, are convenient for use and actively promote reduction of an agricultural investment and improvement of an agricultural product yield.

Description

technical field [0001] The invention relates to a pesticide granule for preventing and controlling the root-knot nematode of crops, in particular to an emamectin and diazinon granule. Background technique [0002] Plant parasitic nematodes mainly include: Meloidogyne, Rotylenchulus, cyst nematodes (Heterodera), root spot nematodes (Pratykenchus), nematodes The damage can greatly reduce the absorption of nutrients and water by the plants. The nematodes cause wounds to the plants and cause the invasion of plant pathogens. [0003] At present, the chemicals used to prevent and control nematodes include highly toxic pesticides such as fenamiphos, carbofuran, terbufos, and thiamephos. Due to the long-term single use of these pesticides, nematodes are relatively resistant to them, and they also cause hidden dangers to environmental pollution. . [0004] Emamectin benzoate, common name in English, is a biological source insecticide. This product is highly efficient, broad-spectr...
