Problems solved by technology

[0005] At present, the domestic treatment of jasmine canopy is mainly based on the control of chemical agents, such as using 2500 times of Guoguang propiconazole (25% EC) or 1500 times of Guoguang azoxystrobin. The advantages of silkworms, but long-term use of chemical treatment, coupled with the private addition of other pesticides by farmers, not only greatly increases the cost of using medicines, large pesticide residues, serious loss of pesticides, and long-term consumption of this kind of pesticides Drugs and food can cause chronic toxicity to the human body, especially delayed neurotoxicity, which has threatened the living environment of human beings; in addition, the wide application of chemical agents has endangered ecological agriculture and caused serious damage to soil and water resources. Pollution, which is seriously inconsistent with the concept of green, environmental protection, health and sustainable development advocated by modern times

Abstract

The invention belongs to the technical field of plant disease and pest prevention and particularly relates to a method using Baeckea frutescens branch and leaf extract to prevent and treat jasmine southern blight. The method includes: using the Baeckea frutescens branch and leaf extract to soak the roots of jasmine seedlings before jasmine seedling transplanting, and spraying the Baeckea frutescens branch and leaf extract to the jasmine seedlings after transplanting and planting; using the Baeckea frutescens branch and leaf extract to perform root irrigation on diseased jasmine plants which have the preliminary symptoms of the southern blight and the jasmine plants adjacent to the diseased jasmine plants and the like. By the method, jasmine southern blight can be effectively prevented, theharm of the southern blight in the growth process of jasmine can be lowered, the use amount and times of chemical pesticides can be reduced. In addition, the method is safe, environmentally friendly,free of pesticide residues and free of threat to human bodies and environments.

Description

technical field [0001] The invention belongs to the technical field of protection against plant diseases and insect pests, and in particular relates to a method for preventing and treating jasmine silkworm by using extracts from pine branches and leaves. Background technique [0002] Jasmine mildew is a major disease of jasmine roots, which is known by flower farmers as rot, white hair disease, rapeseed disease, etc., and the disease generally occurs in jasmine planting areas. Jasmine mildew is prone to occur during the rainy season and high temperature and humidity in northern Jiangsu. In the early stage of the disease, the root and neck of potted jasmine near the ground change color and gradually rot, and gradually spread and expand to form a white silky silk film. Later, sclerotia appear on the lesions, which are white at first and then yellow to dark brown. Only rapeseed sample size. But the phloem of the susceptible part is rotten, the nutrition of the plant is blocke...
