Embodiment 1

[0022] Guaiacol 0.0005%-1% can be used to control rice diseases.

[0023] Applying guaiacol to the prevention and treatment of rice diseases, its field application includes the following steps:

[0024] S1. Prepare a guaiacol medicinal solution, which includes 1% acetic acid, 0.5%-1% chitosan, 0.001%-1% guaiacol, and 0.1%-25% lignosulfonate as a solvent.

[0025] S2. Applying pesticides, taking the guaiacol liquid configured in step S1 to spray the rice stems and leaves, and the spraying amount is 200-1000L / hm 2 , the spray pressure is 0.3-0.8kPa, and the spraying frequency is 2-3 times.

Embodiment 2

[0027] Applying guaiacol to the prevention and treatment of rice diseases, using the poisonous soil method to apply includes the following steps:

[0028] S11. Make guaiacol into wettable powder, its auxiliary agent includes one or more of dispersant, penetrating agent, wetting agent, adhesive agent, the guaiacol content of described wettable powder is 30% .

[0029] S12. Use the poisonous soil method to apply pesticides, take the guaiacol wettable powder prepared in step S1, use 50 grams of 10%-50% guaiacol wettable powder per mu, mix with 20 kg of moist fine soil, and mix well , Sprinkle the medicinal soil on the rice leaves and leaf sheaths at the lower part of the rice plant. There should be a 5 cm water layer in the field of application, and keep water for 5 days.

Embodiment 3

[0031] The plate method was used to determine the antibacterial activity of guaiacol single agent on the mycelial growth of Fusarium wilt of rice, and the antibacterial rate of the concentration of the agent to inhibit the mycelial growth of Fusarium oryzae was shown in the table below.

[0032]

[0033] It can be seen from the above table that under the condition of only using a single agent of guaiacol, the growth of sheath blight bacteria is significantly inhibited in the concentration range of 50ug / ml-500ug / ml, which proves that the single agent of guaiacol is suitable for Control rice diseases.

Abstract

The invention discloses application of guaiacol in prevention and treatment of rice diseases and an application method of the guaiacol. The guaiacol is applied to the agricultural field and is used for preventing and treating rice diseases, and new use of the guaiacol is developed. By spraying the guaiacol together with chitosan and other aids or by applying the guaiacol by virtue of a toxic clay method, the rice diseases can be effectively prevented and treated. Compared with other disease preventing and resisting pesticides in the prior art, the guaiacol is relatively low in production cost and is worthy of being popularized.

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 preventing and treating rice 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 rice diseases, and provides its application method, which fills up the blank of guaiacol in this field. For the prevention and treatment of rice diseases, the application c...
