Application and application method of guaiacol in prevention and treatment of pepper diseases

Abstract

The invention discloses application and an application method of guaiacol in prevention and treatment of pepper diseases. The guaiacol is applied in the agricultural field. The new application of guaiacol is developed for preventing and treating the pepper diseases, guaiacol is sprayed in cooperation with chitosan and other auxiliaries during application, and the pepper diseases can be effectively prevented and treated; compared with other existing disease-prevention and disease-resistance pesticides, guaiacol is low in production cost and worthy of popularization.

Description

technical field

[0001] The invention relates to the field of pesticides, in particular to the application and application method of a guaiacol single agent in the field of preventing and treating pepper 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 pepper diseases, and provides its application method, which fills up the blank of guaiacol in this field. For the prevention and treatment of pepper diseases, the applicatio...

Examples

Embodiment 1

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

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

[0023] More specifically, the application method of the described guaiacol in the prevention and treatment of pepper 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 pepper 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...

Embodiment 2

[0033] The antibacterial activity of guaiacol single agent on the growth of Xanthomonas herpes mycelium was determined by the plate method, and the antibacterial rate of the concentration of the agent to inhibit the growth of Xanthomonas herpes 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 Xanthomonas herpes was significantly inhibited in the concentration range of 50ug / ml-500ug / ml, which proves that the single agent of guaiacol It is suitable for the prevention and treatment of pepper diseases.
