Embodiment 1

[0024] Embodiment one: (1.5% boluohui total alkaloid water dispersible granule)

[0025] Take Boluohui total alkaloids 15kg Boluohui total alkaloids, 270kg camellia saponins, 10kg lignosulfonate, 10kg tea seed polysaccharide, 150kg nonylphenol polyoxyethylene ether, 5kg alkylbenzene Sulfonic acid, 10 kilograms of gum arabic, and the carrier attapulgite are added to 1000 kilograms. In a three-dimensional mixer, the components of the formula are mixed evenly, and pulverized by ultra-fine airflow to obtain a fine powder of 500 mesh to 1000 mesh. Swing granulator granulation, microwave vacuum drying, sieving, sampling inspection, packaging and warehousing. The 800-fold solution of the preparation was used to conduct a field drug efficacy test, and the control effects on tomato early blight were 76.5% and 83.1% on the 8th day and 15th day after the application.

Embodiment 2

[0026] Embodiment two: (2.5% boluohui total alkaloid water dispersible granule)

[0027] Take Boluohui total alkaloids 25kg Boluohui total alkaloids, 270kg camellia saponins, 10kg lignosulfonate, 10kg tea seed polysaccharide, 150kg nonylphenol polyoxyethylene ether, 5kg alkylbenzene Sulfonic acid, 10 kilograms of gum arabic, and the carrier attapulgite are added to 1000 kilograms. In a three-dimensional mixer, the components of the formula are mixed evenly, and pulverized by ultra-fine airflow to obtain a fine powder of 500 mesh to 1000 mesh. Swing granulator granulation, microwave vacuum drying, sieving, sampling inspection, packaging and warehousing. The 1000-fold liquid of the preparation is used for field drug efficacy test, and the control effects on tomato early blight are 81.5% and 90.0% respectively on the 8th day and the 15th day after the application.

Embodiment 3

[0028] Embodiment three: (5% boluohui total alkaloid water dispersible granule)

[0029] Take 50 kg of Bo Luohui total alkaloids, 270 kg of camellia oleifera saponins, 10 kg of lignosulfonate, 10 kg of tea seed polysaccharides, 150 kg of nonylphenol polyoxyethylene ether, 5 kg of alkylbenzene Sulfonic acid, 10 kilograms of gum arabic, and the carrier attapulgite are added to 1000 kilograms. In a three-dimensional mixer, the components of the formula are mixed evenly, and pulverized by ultra-fine airflow to obtain a fine powder of 500 mesh to 1000 mesh. Swing granulator granulation, microwave vacuum drying, sieving, sampling inspection, packaging and warehousing. The 1500-fold solution of the preparation was used to carry out the field drug efficacy test, and the control effects on tomato early blight were 82.1% and 95.3% on the 8th day and the 15th day after the application.

[0030] The above examples have been used to show that the Boluohui total alkaloid water-dispersible ...

Abstract

The invention discloses a Macleaya cordata total alkaloids water dispersion granule disinfectant, which comprises the following components by weight percentage: 1.5 percent to 5 percent of Macleaya cordata total alkaloids, 10 percent to 30 percent of sasanguasaponin, 1 percent to 15 percent of disintegrant, 1 percent to 15 percent of dispersant, 1 percent to 15 percent of wetting agent, 0.5 percent to 1 percent of caking agent, 0.5 percent to 1 percent of stabilizing agent and the rest of carrier. The invention also discloses a preparation method of the disinfectant. The Macleaya cordata total lakalioids is used for being made into plant farm chemical water dispersion granule, so the application range of the chemical can be enlarged, the lasting period can be prolonged, and the drug action can be improved; not only can the damage to the ecological environment be alleviated, but also the production cost can be reduced, and the toxic effect on different natural enemies can be greatly alleviated; and the disinfectant is convenient to pack, store and transport.

Description

technical field [0001] The invention relates to the field of pesticide production, and relates to a plant pesticide preparation and a preparation method thereof, in particular to a water-dispersible granule fungicide of boluohui total alkaloids and a preparation method thereof. technical background [0002] In the 1980s, a new pesticide dosage form appeared: water-dispersible granules, which quickly became the current pesticide dosage form due to the advantages of less environmental pollution, low toxicity, high content of active ingredients, small product volume, and easy packaging, storage and transportation. The most superior and competitive new dosage form in China. Inventors Zhou Ligang, Wang Jingguo, etc. have disclosed the publication number CN 101352180A "Petrodia alkaloids for inhibiting plant pathogenic bacteria and its preparation method". It has been described that Bodlagui alkaloids are used to inhibit plant pathogens, but the specific dosage form of pesticides ...
