Embodiment 1

[0010]The application of the atractylodes atractylodes essential oil in this implementation, the atractylodes atractylodes essential oil is used for the prevention and treatment of tea tree leaf spot; the EC of the atractylodes root oil for the indoor virulence determination of Pseudopestalotiopsis camelliae-sinensis50It is 0.269mg / mL.

[0011]The essential oil of Atractylodes is obtained by steam distillation. The specific method is:

[0012]Take 200g atractylodes powder through a 26-mesh sieve, place it in a 5000mL round-bottomed flask, add 3000mL of water to soak overnight, and then heat it on a constant temperature electric heating mantle to boil and extract for 6 hours, then stop heating, pass in condensed water and reflux until the extractor is cooled down The liquid flows down from the condenser tube to collect the essential oil of atractylodes.

[0013](1) Laboratory virulence determination of Atractylodes japonicus essential oil on tea tree leaf spot disease

Abstract

The invention provides application of rhizoma atractylodis essential oil. The rhizoma atractylodis essential oil is used for preventing and treating tea tree ring spot. The rhizoma atractylodis essential oil disclosed by the invention has a good inhibition effect on Pseudopestalotiopsis camelliae-sinensis and can be used as a novel botanical pesticide to be developed and used.

Description

Technical field[0001]The invention belongs to the technical field of tea tree disease prevention and treatment, and specifically relates to the application of atractylodes lanceolata essential oil.Background technique[0002]Ring spot disease is one of the main leaf diseases that damage tea trees. It is common in all tea gardens in our country and widely exists in various tea producing areas. It harms the development of the tea industry to varying degrees in different regions, and can cause large areas of tea leaves in severe cases. The necrosis falls off, which affects tree vigor and tea yield and quality. Pestalotiopsis-like species fungi are considered to be the pathogens of tea tree leaf spot. At present, the main measures for the prevention and control of tea plant diseases in tea gardens are the use of chemical pesticides, which occupy a very important position. However, chemical pesticides have the characteristics of environmental pollution and resistance to tea. Therefore, it ...
