Problems solved by technology

[0002] Guaiacol is a white or light yellow crystal or colorless to light yellow transparent oily liquid with a special aromatic smell. Existing in guaiac wood resin, pine oil and hardwood dry distillation oil, it is an important fine chemical intermediate, widely used in the synthesis of medicine, spices and dyes, and rarely used in other fields in existing production and life literature and technology

Embodiment 1

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

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

[0023] More specifically, the method for applying guaiacol in the prevention and treatment of sweet potato diseases is characterized in that it comprises the following steps:

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

[0025] S2. Pesticide application, taking the guaiacol liquid prepared in step S1 to spray the sweet potato stems and leaves.

[0026] More specifically, the guaiacol liquid also contains one or more of dispersants, adhesives, penetrants, emulsifiers, preservatives, and antifreeze agents.

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

Embodiment 2

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

[0034]

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

Abstract

The invention discloses application of guaiacol to control of sweet potato diseases and an application method. The guaiacol is applied to control of the sweet potato diseases in the agricultural field, so that novel application of the guaiacol is developed; during application, the guaiacol is sprayed in coordination with chitosan and other auxiliary agents, so that the sweet potato diseases can be effectively controlled; in addition, compared with the conventional other disease-preventing and disease-resisting pesticides, the guaiacol has the advantages of relatively low production cost and worthiness of popularization.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the application and application method of a single agent of guaiacol in the field of controlling sweet 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 smell. Existing in guaiac wood resin, pine oil and hardwood dry distillation oil, it is an important fine chemical intermediate, widely used in the synthesis of medicine, spices and dyes, and rarely used in other fields in existing production and life literature and technology. Contents of the invention [0003] The present invention develops the application of guaiacol in the field of agriculture, especially in the prevention and treatment of sweet potato diseases, and provides its application method, which fills up the blank of guaiacol in this field. For the prevention and treatment of sweet potato diseases, the a...
