Plant-source natural fungicide for preventing and controlling botrytis cinerea and preparation method thereof

Abstract

The invention provides a plant-source natural fungicide for preventing and controlling botrytis cinerea, which comprises the following raw materials: garlic essential oil, a plant essential oil mixture, an organic solvent, a surfactant and water. The garlic essential oil servers as the main fungicide, and more than two other plant essential oils serve as synergists, thus the efficiency of killing the botrytis cinerea can be improved. Due the combination of different chemical components of the plant essential oils, even under the condition of reducing the use amount, the purpose of preventing and controlling the botrytis cinerea can still be achieved, and the resistance to the plant-source natural fungicide of one or more compounds can be prevented. The plant-source natural fungicide comprises complex chemical components and also comprises functional groups formed by several kinds of chemical components, thus the efficiency of fulfiling the function of the plant-source natural fungicide is enhanced, the synergistic forms are increased, the permeability of the chemical components is improved, and the compound can take effect on the crops for a long time. Because the chemical components of the plant-source natural fungicide are natural medical plants, the plant-source natural fungicide is not-toxic to humans and animals and is safe to environment.

Description

technical field [0001] The invention belongs to the field of plant fungicides, and in particular relates to a botanical natural fungicide for tomato cinerea. The raw materials of the fungicide contain garlic essential oil, a mixture of plant essential oils, an organic solvent, a surfactant, and water; The fungicide is non-toxic to humans and animals and safe to the environment. Background technique [0002] At present, the cost of controlling pests with chemical pesticides is as high as 10 billion U.S. dollars every year in the world. Even so, the annual losses caused by pests still account for 20-30% of the total crop output. However, due to a series of problems such as environmental pollution, human and animal poisoning caused by long-term use of chemical pesticides, and increased resistance of diseases and insect pests, some countries have begun to take measures to restrict and ban chemical pesticides. Especially in 1992, after the World Conference on Environment and Dev...

Problems solved by technology

[0009] However, the common botanical pesticides and chemical pesticides currently on the market have the following obvious problems in the market competition: first, the drug effect is slow, the drug effect period is short, and the antibacterial and insecticidal efficiency is low; second, the production cost is high; The efficacy of Botrytis cinerea is not strong; these three factors limit the industrial development of botanical pesticides. In production practice, it is necessary to solve the problem of high efficiency and long-term effect of existing products, which are harmless to humans and animals and environmentally friendly.
