Embodiment 1

[0020] Efficacy Example 1 Control effect of the composition of azoxystrobin and Bacillus subtilis on rice sheath blight

[0021] The test summary and results are shown in the table below:

[0022]

[0023] It can be seen from the test results that under the condition that the active ingredients are almost the same, the combination of Bacillus subtilis and azoxystrobin greatly improves the control effect, and the control effect is much higher than the two single-agent treatments of Bacillus subtilis and azoxystrobin , indicating that the combination of the two has a synergistic effect.

Embodiment 2

[0024] Efficacy Example 2 Control effect of the composition of azoxystrobin and Bacillus subtilis on wheat head blight

[0025] The test summary and results are shown in the table below:

[0026]

[0027] It can be seen from the test results that under the condition that the active ingredients are almost the same, the control effect of the combination of Bacillus subtilis and azoxystrobin is much higher than that of the two single-agent treatments of Bacillus subtilis and azoxystrobin, indicating that the combination of the two can The control effect on wheat head blight is greatly improved, indicating that the combination of the two has a synergistic effect.

Embodiment 3

[0028] Drug effect example 3 The effect of the composition of azoxystrobin and Bacillus subtilis on the prevention and control of rape sclerotinia

[0029] The test summary and results are shown in the table below:

[0030]

[0031] It can be seen from the test results that under the condition that the active ingredients are almost the same, the control effect of the combination of Bacillus subtilis and azoxystrobin is much higher than that of the two single-agent treatments of Bacillus subtilis and azoxystrobin, indicating that the combination of the two can Greatly improved the control effect on rape sclerotinia, indicating that the combination of the two has a synergistic effect.

Abstract

The invention discloses a biocontrol bacterium and azoxystrobin composition belonging to the technical field of bactericides. The biocontrol bacterium and azoxystrobin composition contains active components including bacillus subtilis and azoxystrobin. The biocontrol bacterium and azoxystrobin composition disclosed by the invention can be used for remarkably reducing the medication cost while effectively preventing and controlling various diseases such as rice sheath blight disease, rice false smut, rice blast, ear rot, seedling-stage damping-off, tomato late blight, gray mold, wheat powdery mildew, sheath blight, cotton rhizoctoniosis, foxysporum, verticillium dahliae, soybean root rot, corn sheath blight, cucumber gray mold, blight, tobacco brown spot, bacterial wilt, various field crop and garden crop root rots and damping off, so that the medication cost can be reduced, the preventing and controlling ranges can be widened, the environment pollution can be reduced, and the phytotoxicity and pesticide resistance risks can be reduced.

Description

technical field [0001] The invention belongs to the technical field of fungicides, and in particular relates to a composition of biocontrol bacteria and azoxystrobin. Background technique [0002] Bacillus subtilis is a kind of Bacillus, which is widely distributed in the natural environment and is often used in industrial and agricultural fields as a beneficial microorganism. In the field of plant protection, the fungus is mainly used to fight against a variety of pathogenic fungi of the genera Fusarium, Aspergillus, Alternaria and Rhizoctonia through competition, lysis, secretion of antibiotic substances, induction of resistance, and promotion of host growth. All have biocontrol functions, against rice sheath blight, rice smut, rice blast, seedling blight, tomato late blight, tomato gray mold, wheat powdery mildew, wheat sheath blight, cotton sore blight, cotton wilt Bacteria, cotton verticillium wilt, soybean root rot, corn sheath blight, cucumber gray mold, cucumber wil...
