Abstract

The invention discloses an application of lavender essential oil. In order to achieve green control of crop diseases, efficient sterilization activity components are selected from aromatic plant sources, and antibacterial activity of the lavender essential oil for phytophthora parasitica is detected by a mycelial growth method. The results show that when the concentration of the lavender essentialoil reaches 250 micro-liters / liters, the lavender essential oil has remarkable inhibiting effect on the phytophthora parasitica. Dosage effect experiment results show that by a fumigation mode, an EC50 value of the lavender essential oil for inhibiting the phytophthora parasitica is 255.20 micro-grams / milliliters. Piece inserting method experiment results show that the lavender essential oil hasa certain effect on phytophthora parasitica mycelial growth. The lavender essential oil has the advantages that the oil is environmentally friendly, low in cytotoxicity and wide in spectrum, strain drug resistance is avoided and the like. The lavender essential oil is expected to be an environment-friendly novel pesticide for preventing and treating the phytophthora parasitica.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to the application of lavender essential oil. Background technique [0002] Phytophthora tobacco ( Phytophtora parasitica var. nicotianae Tucker) is a soil-borne pathogen with a wide range of hosts, which seriously harms tobacco and other Solanaceae crops worldwide, especially in Yunnan tobacco-growing areas, causing serious economic losses to tobacco farmers. Phytophthora nicotiana can cause root and stem rot and leaf withering, and can infect and cause disease in various growth stages of tobacco growth. At present, the prevention and control of this disease mainly adopts the method of continuous and large-scale use of chemical pesticides, which leads to the generation of pathogenic bacteria resistant physiological races, the destruction of soil microbial communities, the destruction of farmland ecological environment, and the impact of excessive pestici...
