Problems solved by technology

[0004] 1) The increased drug resistance of pathogens leads to an increase in the number of carbendazim spray irrigation and an increase in the amount of one-time control application;
[0005] 2) The ecological and environmental problems of the beech woodland caused by the control of chemical pesticides, for example, the soil is easy to harden and the fertility is reduced;
[0006] 3) Long-term application of chemical pesticides will affect the species and structural composition of the bacterial community in the soil

Embodiment 1

[0045] 1) Ditch circularly within the radius of 0.8-1.5m of the beech tree trunk; the position of the ditch expands outward year by year according to the age of the beech tree, the excavation width is controlled at 60-100cm, and the excavation depth is controlled at 40-50cm;

[0046] 2) 13 parts of Streptomyces flavinus CICC 23627 fermentation broth, 12 parts of 300 times liquid Condirad (Paenibacillus polymyxa fine granule), prepared solution for root irrigation, 1500 mL per plant, as treatment 1;

[0047] 3) Streptomyces flavinus CICC 23627 fermentation broth 13 parts by mass, 300 times liquid Condilet (Paenibacillus polymyxa granule) 12 parts, citral fungicide 5 parts, 500 times liquid carbendazim for sterilization 3 parts of prepared solution for root irrigation, 1500mL per plant, as treatment 2;

[0048] 4) 13 parts by mass of Streptomyces luteus CICC 23627 fermentation broth, 5 parts of citral fungicide, and 3 parts of 500-fold liquid carbendazim fungicide were prepared ...

Embodiment 2

[0058] The medicament for the prevention and treatment of beech root rot comprises the following components in parts by mass: 18 parts of Streptomyces luteus CICC 23627 fermented liquid, 15 parts of Condirad, 8 parts of citral fungicide and 6 parts of carbendazim fungicide .

[0059] The method for using the above-mentioned control agent to prevent and treat beech root rot may further comprise the steps:

[0060] 1) each component is prepared the prevention and treatment agent of beech root rot according to the ratio of parts by mass;

[0061] 2) Ditch circularly within the radius of 0.8-1.5m of the beech tree trunk, the width of the ditch is controlled at 60-100cm, and the depth of the ditch is controlled at 40-50m;

[0062] 3) Pour the control agent of zelkova root rot into the annular ditch, and carry out the root irrigation treatment according to 1000-1500mL of each zelkova;

[0063] 4) After the root irrigation is completed and the control agent penetrates into the soil...

Embodiment 3

[0066] It is basically the same as Example 2, except that the control agent includes the following components in parts by mass: 15 parts of Streptomyces flavinus CICC 23627 fermented liquid, 13 parts of Kangdirad, 6 parts of citral bactericide and multibacterial Ling bactericide 5 parts.

[0067] The various components of the prevention and control agent of the present application cooperate with each other to increase efficiency, and the control effect is obvious, and the microbial agent effectively inhibits the growth and reproduction of pathogenic bacteria of beech root rot and provides a favorable environment for the reproduction of beneficial microorganisms .

Abstract

The invention discloses a prevention and treatment agent and method for root rot of zelkova schneideriana, and belongs to the field of plant protection. The prevention and treatment agent is preparedfrom the following components in parts by weight: 13-18 parts of streptomyces microflavus CICC 23627 fermentation broth, 12-15 parts of Kangdeleide, 5-8 parts of citral bactericide and 3-6 parts of carbendazim bactericide. The method for preventing and treating root rot of zelkova schneideriana by using the agent comprises the following steps: (1) annularly ditching within the radius range of 0.8-1.5 m of the trunk of zelkova schneideriana with a ditching width of 60-100 cm and a ditching depth of 40-50 m; 2) irrigating the annular ditch with the prevention and treatment agent, wherein 1000-1500 mL of the prevention and treatment agent is irrigated to each zelkova schneideriana for root irrigation treatment; and 3) after root irrigation is completed, carrying out soil filling treatment onthe annular ditch. According to the prevention and treatment agent, the application amount of chemical pesticides is reduced, poison to soil and plants is reduced, all the components cooperate with one another to achieve a synergistic effect, and growth and propagation of pathogenic bacteria of the root rot of zelkova schneideriana can be effectively inhibited.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a control agent and a control method for beech root rot. Background technique [0002] Beech root rot is a relatively serious disease that has occurred in the Maoshan area of ​​Jurong City, Jiangsu Province in recent years. Seedlings, saplings, and large trees are all affected by this disease. It starts to show that the leaves turn yellow and curl, and a few leaves wither or even fall off; the roots and stem bases rot and turn black. When a big tree gets sick, a whole circle of discoloration rings can appear on the trunk and branch cross-section. In the longitudinal section, light yellow-brown longitudinal stripes can be seen running upward from the rhizosphere. The closer to the root, the darker the vertical stripes are. It becomes darker, shrinks and is easy to separate from the xylem, the leaves turn yellow and wither and fall off, the branches die, and finally the...
