Embodiment 1

[0026] Control effect embodiment 1, indoor virulence assay of preventing and treating rice sheath blight

[0027] For the experimental method, refer to "Agricultural Industry Standard of the People's Republic of China NY / T1156.5-2006 Indoor Bioassay Test Guidelines for Pesticides Fungicide Part 5: Test for Inhibition of Rice Sheath Blight Bacteria and Broad Bean Leaf Method". Firstly, 9 different ratios are set for the single agent and each mixed agent. Select broad bean susceptible varieties as potted plants, cut out the same parts, suppress the growth, put the leaves with petioles in a petri dish, and keep them moist for later use. Fully soak the leaves in the pre-prepared medicinal solution for 5 seconds, drain off the excess medicinal solution, and after natural air-drying, follow the treatment label and then moisturize and cultivate. Use an inoculator to inoculate the side of the bacterium cake with a diameter of 5 mm that has mycelium in the center of the treatment blad...

Embodiment 2

[0033] Control effect embodiment 2, indoor drug efficacy determination of control cotton blight

[0034] experimental method

[0035] The test uses the growth rate method (plate method). On the aseptic operating table, according to the test treatment, quantitatively add the pre-thawed sterilized medium into the sterile Erlenmeyer flask, take 5 ml of the liquid medicine from low concentration to high concentration, and add them respectively to 45 ml of hot medium. (40-45 degree) Erlenmeyer flask, after shaking up, pour into the glass petri dish of diameter 90 millimeters rapidly, each petri dish is poured into 10 milliliters of culture medium with medicine. Lay horizontally and form into flat plates after cooling. 5 replicates for each concentration. The treatment without the active ingredient of the drug was used as the blank control. Use a sterilized puncher with a diameter of 4mm to steal the bacteria cake from the edge of the colony under sterile conditions, and inocula...

Embodiment 3

[0041] Control effect embodiment 3, field test control rice sheath blight

[0042] experiment method

[0043] The experiment was carried out in the paddy area of ​​Jianli, Hubei, with an area of ​​15 square meters, and was repeated 4 times. Sampling at five diagonal points in each plot, surveying 0.1 square meters at each point, recording the total number of investigated plants, the number of diseased plants, and the number of disease grades.

[0044] Survey time and frequency

[0045] A total of 4 investigations were conducted in the test, including base investigation before the drug, 7 days after the first drug, 7 days after the second drug and 15 days after the drug.

[0046] Dosage Form and Method of Administration

[0047] The dosage form of the composition of the invention is a suspension concentrate, the application method is spraying, and the dosage is 30 liters / mu.

[0048] Drug efficacy calculation method

[0049] Grading standards:

[0050] Grade 0: The whole ...

Abstract

The invention relates to the technical field of combination of pesticides, and discloses a benziothiazolinone and thifluzamide containing fungicide composite. The fungicide composite comprises the effective components of benziothiazolinone and thifluzamide based on the mass ratio of 1: 40-40: 1; the total mass of the effective components accounts for 1-80% of the total mass of the whole preparation, and the rest is the assisting component. The fungicide composite can be prepared into a suspending agent, a dispersible oil suspending agent, wettable powder and water dispersible granules. The fungicide composite has an obvious synergistic interaction function and is mainly used for controlling and preventing banded sclerotial blight and damping off.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing thiamethoxam and thifuramide, which is mainly used for preventing and curing sheath blight and blight. [0002] technical background [0003] Thiemadone is a high-efficiency, low-toxicity, broad-spectrum fungicide, which can destroy the cell membrane protein and synthesis system of pathogenic bacteria, thereby inhibiting the reproduction of pathogenic bacteria, interfering with the metabolism of pathogenic bacterial cells, making them physiologically disordered, and leading to the death of pathogenic bacteria. The compound has good control effects on various crop diseases caused by bacteria and fungi, and is very safe to crops and the environment. [0004] Thiofuramide, belonging to the thiazole amide fungicides, has strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor. Becaus...
