Problems solved by technology

[0004] Although trifloxystrobin has the advantages of high efficiency, quick effect, strong systemic absorption, and resistance to rain erosion, it also has many defects such as drug resistance risk and high production cost.
As a biological pesticide, Bacillus subtilis has the advantages of being environmentally friendly, low production cost, not easy to produce resistance and long-lasting effect, but it also has the disadvantages of slow effect and high requirements on environmental conditions

Embodiment 1

[0020] Efficacy Example 1 Control effect of the composition of trifloxystrobin 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 trifloxystrobin greatly improves the control effect, and the control effect is much higher than the two single-agent treatments of Bacillus subtilis and trifloxystrobin , indicating that the combination of the two has a synergistic effect.

Embodiment 2

[0024] Efficacy Example 2 Control effect of the composition of trifloxystrobin 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 conditions of almost the same active ingredients, the control effect of the composition of Bacillus subtilis and trifloxystrobin is much higher than that of the two single-agent treatments of Bacillus subtilis and trifloxystrobin, 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 trifloxystrobin 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 conditions of almost the same active ingredients, the control effect of the composition of Bacillus subtilis and trifloxystrobin is much higher than that of the two single-agent treatments of Bacillus subtilis and trifloxystrobin, 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 trifloxystrobin composition, and belongs to the technical field of bactericides. The composition contains the following active components: Bacillus subtilis and trifloxystrobin. The composition can effectively control rice sheath blight, rice false smut, rice blast, seedling blight, tomato late blight, tomato botrytis, wheat powdery mildew, wheat sheath blight, cotton Rhizoctonia solani Kuhn, cotton fusarium wilt, cotton verticillium wilt, soybean root rot, corn sheath blight, cucumber botrytis, cucumber wilt, tobacco brown spot, tobacco bacterial wilt disease, various field and garden crop root rot, seedling blight and other various diseases, and substantially reduces the pesticide cost, so the pesticide cost is reduced, the control range is enlarged, environmental pollution is reduced, and the pesticide harm and the pesticide resistance risk are 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 trifloxystrobin. 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 mainly inhibits various fungi of the genus Fusarium, Aspergillus, Alternaria and Rhizoctonia through competition, lysis, secretion of antibiotic substances, induction of resistance, and promotion of host growth. It has a biocontrol effect on rice sheath blight, rice smut, rice blast, rice seedling blight, tomato late blight, tomato gray mold, wheat powdery mildew, wheat sheath blight, cotton blight, Cotton Fusarium Wilt, Cotton Verticillium Wilt, Soybean Root Rot, Corn Sheath Blight, Cucumber Botrytis, Cucumber Fusarium Wilt, Tobacco Red Spot, Tobacco Ba...
