[0027] Bioassay Example 1 : Indoor Toxicity Determination of Berberine and Orysastrobin Complex to Bacterial Leaf Spot of Rice
[0028] Test object: Bacterial leaf spot of rice collected from the field
[0029] 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 (Half Maximal Effective Concentration, EC50) were calculated...
Embodiment 1
[0043] Example 1 : 1% Berberine. Orysastrobin Granules
[0044]
[0045] Add xylene to berberine and orysastrobin, then stir them well to dissolve them completely; under stirring, slowly add propylene glycol into the system, stir well for 30 minutes to dissolve them completely and form a stable solution .
[0046] 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. Oryzastrobin Granules.
Embodiment 2
[0047] Example 2 : 10% Berberine. Oryzastrobin Microcapsule Suspension Concentrate
[0048]
[0049]
[0050] Dissolve 2% prothiostrobin and 8% orysastrobin in 5% xylene, then pump in 0.3% tributyl phosphate, 2.4% carboxymethyl cellulose, and 2.7% sodium alginate in high shear Cut the kettle and shear at high speed 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, Stir evenly to get 10% berberine · orysastrobin microcapsule suspension.
