Embodiment 1

[0021] Guaiacol 0.001%-1% can be used to prevent and control potato diseases.

[0022] More specifically, the application concentration of guaiacol is 0.005%-0.05%.

[0023] More specifically, the application method of guaiacol for preventing and treating potato diseases is characterized in that it comprises the following steps:

[0024] S1. Configure guaiacol medicinal solution, which includes guaiacol 0.02%-0.5%, and the solvent is water.

[0025] S2. Spraying, taking the guaiacol liquid prepared in step S1 and spraying the potato stems and leaves.

[0026] More specifically, the guaiacol medicinal solution also contains one or more of dispersant, adhesive, penetrant, emulsifier, preservative, and antifreeze.

[0027] More specifically, the dispersant is one or two of fatty acid dispersant and alkali metal phosphate; wherein the concentration of the fatty acid dispersant is 0.1%-5%; wherein the alkali metal phosphate dispersant The concentration is 0.1%-5%.

[0028] More specifically, ...

Embodiment 2

[0033] The plate method was used to determine the antibacterial activity of a single agent of guaiacol on the growth of Pseudomonas solanacearum hyphae. The antibacterial rate of the agent concentration to inhibit the growth of Pseudomonas solanacearum is shown in the table below.

[0034]

[0035] It can be seen from the above table that the growth of Pseudomonas solanacearum is significantly inhibited in the concentration range of 50ug / ml-500ug / ml under the condition of using only guaiacol single agent, which proves that guaiacol single agent Suitable for preventing and controlling potato diseases.

Abstract

The invention discloses application of guaiacol to control over potato diseases and an application method. Guaiacol is applied to the field of agriculture to control the potato diseases, new application of guaiacol is developed; when combined with chitosan and other auxiliaries for spraying during application, the guaiacol can effectively control the potato diseases, and compared with existing other disease-resistant pesticides, the guaiacol is low in production cost and worth popularizing.

Description

Technical field [0001] The invention relates to the field of pesticides, in particular to the application and application method of a single guaiacol agent in the field of preventing and controlling potato diseases. Background technique [0002] Guaiacol is a white or light yellow crystal or colorless to light yellow transparent oily liquid with a special aromatic odor. Its scientific name is o-hydroxyanisole, glycerol ether, guaiacol glycerol ether, o-hydroxyglycerol ether, etc., in nature It exists in guaiac resin, pine oil and hardwood retort oil. It is an important fine chemical intermediate. It is widely used in the synthesis of medicine, perfume and dye. It is rarely used in other fields in existing production and life. Literature and technology. Summary of the invention [0003] The present invention develops the application of guaiacol in the agricultural field, especially in the prevention and treatment of potato diseases, and provides its application method, filling the...
