Abstract
The invention relates to a pesticide composition containing extracts of folium isatidis and thyme and a preparation method and application thereof, belongs to the field of pesticides, and provides the pesticide composition containing the extracts of the folium isatidis and the thyme in order to solve the technical problem. Active components of the pesticide composition containing the extracts of the folium isatidis and the thyme are extracted from the following raw medicinal materials in parts by weight: 10 to 30 parts of folium isatidis and 1 part of thyme. The common extracts of the folium isatidis and the thyme have a synergistic effect, and the effect of preventing and treating damping off of crops is obvious; by the adoption of the folium isatidis and the thyme for joint extraction, the contents of epigoitrin, thymol and other bacterial active components with main groups basically the same as those in the epigoitrin and the thymol are increased; the damping off is prevented and treated, the immunitysystem of the crops can be improved, and the activity of the crops can be obviously enhanced; traditional Chinese herbs are used as raw materials, so that pesticide residues are avoided; compared with an independently used chemical-source pesticide, the pesticide composition is environment-friendly; meanwhile, when the pesticide composition is used, the effective concentration is low, and the cost is low.
