[0028] Bioassay Example 1 : Indoor Toxicity Determination of Berberine and Azoxystrobin Compound to Rice Bacterial Leaf Spot Pathogen

[0029] Test object: Bacterial leaf spot of rice collected from the field

[0030] Test method: make the mother liquor with a certain concentration of the test agent, and then dilute it with water according to the set ratio to prepare 5-6 concentrations. Set clean water as the control, and add the concentration of bacteria containing 1×10 7 In the cfu / mL NB culture medium, in a constant temperature shaker at 28°C and 130r / m, after culturing for 24 hours, use a UV spectrophotometer to measure the absorbance value at a wavelength of 600nm, and calculate the antibacterial rate according to formula 2-3. The drug concentration was converted into logarithm, and the bacteriostatic rate was converted into a probability value for linear regression, and the toxicity regression equation and EC50 value (HalfMaximalEffectiveConcentration, EC50) were calcul...

Embodiment 1

[0045] Example 1 : 1% Berberine. Azoxystrobin Granules

[0046]

[0047] Add xylene to berberine and azoxystrobin, and then stir them fully to dissolve them completely; under stirring, slowly add propylene glycol to the system, stir fully for 30 minutes, dissolve them completely, and form a stable solution.

[0048] First add 12-60 mesh zeolite into the mixer, then add the above stable solution into it, mix for 30 minutes, after screening and testing, you can get 1% berberine. Azoxystrobin granules.

Embodiment 2

[0049] Example 2 : 10% Berberine. Azoxystrobin microcapsule suspension

[0050]

[0051]

[0052] Dissolve 2% prothiostrobin and 8% azoxystrobin in 5% xylene, then pump in 0.3% tributyl phosphate, 2.4% carboxymethyl cellulose, and 2.7% sodium alginate under high shear High-speed shear in the kettle for 30 minutes, add 20% urea-formaldehyde resin prepolymer, heat up and solidify for 60 minutes under stirring at 2000 rpm, then add deionized water, 4.5% sodium dinaphthyl methane disulfonate, 1.8% bentonite, and stir 10% berberine · azoxystrobin microcapsule suspension can be obtained evenly.

Abstract

The invention discloses a sterilization composition containing berberine and azoxystrobin. An effective component is formed by compounding the berberine and the azoxystrobin, wherein the mass ratio of the berberine to the azoxystrobin ranges from (1:9) to (9:1). The sterilization composition disclosed by the invention can be prepared into conventional preparations in pesticide science, such as wettable powder, water dispersible granules, suspension, microcapsule suspension, granules or emulsion in water. The sterilization composition disclosed by the invention has the advantages of high efficiency, small environment pollution and delaying of bacterium drug resistance and the like; and the sterilization composition can be used for preventing and treating diseases of a plurality of types of crops, particularly rice bacterial streak.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a pesticide composition, in particular to a bactericidal composition containing berberine and azoxystrobin. Background technique [0002] During the entire growth process of crops, they are faced with the threat of many pests such as diseases, insects, and weeds. Among them, diseases, especially fungal diseases, are characterized by various types, complex symptoms, rapid spread, serious damage, and compound occurrence. It makes it more difficult to control and poses a huge threat to crop yield and quality. In the process of agricultural production, in order to reduce the losses caused by fungal diseases, chemical control is one of the more significant means at present. The currently used medicaments produce different degrees of resistance, and it is reported that due to this unscientific drug use method, the resistance generation time of various medicaments is shortened year by ...
