Embodiment 1

[0026] Indoor Activity Assay

[0027] Toxicity determination of 50% water dispersible granules compounded with kasugamycin and nano-silver against citrus canker

[0028] Test object: Canker sorrel citrus bacteria was obtained from the laboratory of Dr. Li Pei, Guizhou Kaili College, Qiandongnan Ethnic Medicine Comprehensive Utilization Engineering Technology Research Center.

[0029] Test method: The antibacterial activity of 50% water-dispersible granules of kasugamycin and silver particle composition against X. citri was determined by turbidity method.

[0030] The composition is configured into drug-containing NB medium with different concentration gradients, and the OD of the 5 concentrations of drug-containing sterile NB medium is determined 595 value, which is the OD value of the sterile medium. Then add the bacterial suspension respectively, shake and culture in a constant temperature shaker at 28 °C and 180 rpm / min for 48 h, and measure the OD of each concentration o...

[0043] Embodiment 2: 30% kasugamycin·nanometer silver wettable powder

[0044] Table 2 Component ratio of 30% kasugamycin·nanometer silver wettable powder

[0045]

[0046] Mix the active ingredients, various additives and fillers according to the ratio in Table 2, and pulverize them with an ultrafine pulverizer to obtain 30% kasugamycin·nano silver wettable powder.

Embodiment 3

[0047] Embodiment 3: 10% kasugamycin nano-silver suspension

[0048] Table 3 Component ratio of 10% kasugamycin·nanometer silver dry suspension

[0049]

[0050] The active component kasugamycin former drug, active component nano-silver, sodium lignosulfonate, carboxymethyl cellulose, organosilicon compound and glycerin in Table 3 are added to the water successively by the above-mentioned formula, and the pH is adjusted with hydrochloric acid to 3.5-5.0, you can get 10% kasugamycin · nano silver suspension.

Abstract

The invention relates to a pesticide composition by taking kasugamycin and nano-silver as active components and application thereof. The pesticide composition comprises the active components kasugamycin and nano-silver in a mass ratio of (100:1)-(1:100). After kasugamycin and nano-silver are compounded, an obvious synergistic effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and in particular relates to a pesticide composition with kasugamycin and nano-silver as active components and an application thereof. Background technique [0002] Citrus canker is a bacterial disease caused by X. citri. Xanthomonas citrus pv. citrus Xanthomonas axonopodis pv. citri , citrus canker can infect a variety of Rutaceae plants, and common sweet oranges, navel oranges, limes and other varieties are the most susceptible. The fungus can be spread by splashing raindrops and high-speed wind, through lenticels, stomata and wounds, thereby invading plants, causing crater lesions on leaves, fruits and stems, causing immature fruit rupture, deformity, fruit drop and leaf drop . The current drugs used to prevent and treat canker sores of citrus are mainly single-dose and compound preparations of copper preparations, such as copper hydroxide, copper king, Chunlei • king coppe...
