Abstract

The invention provides a biological plant source miticide prepared from urban greening wastes, and preparation and application of the biological plant source miticide. The biological plant source miticide is composed of 40%-80% of bulk drugs and 20%-60% of conventional auxiliary materials. The bulk drugs comprise the following components in percenrage by weight: 2%-20% of ligustrum lucidum extract, 5%-30% of ailanthus altissima extract, 5%-30% of liriodendron chinensis extract, 5%-10% of camptotheca acuminate extract, 5%-25% of magnolia grandiflora linn extract, 5%-30% of koelreuteria paniculata extract, 5%-20% of cinnamomum camphora extract, 5%-15% of sapium sebiferum extract and 4%-10% of berberis thunbergii DC. extract. The plant extracts are all obtained by drying, powdering, leaching and filtering branches, stems, leaves, flowers and fruits or mixtures of these parts, which are cut from plants, or shed and wasted naturally or wasted in the process of processing other products. The biological plant source miticide is efficient, free from residuals, low in production cost, high in combination property as well as economical, practical and environment-friendly.

Description

technical field [0001] The invention relates to a botanical biological acaricide in the technical field of pesticides, in particular to a botanical biological acaricide made from urban greening waste and its preparation and application. Background technique [0002] Herbivorous mites are found on crops all over the world. They have the characteristics of small size, fast reproduction, strong adaptability and easy resistance to pesticides. They are recognized as harmful biological communities that are difficult to control. At present, most of the acaricides used in China's pesticide market rely on imports, and the cost of imported acaricides accounts for 88.8% of the total cost of imported pesticides. Moreover, the loss of crops caused by mites has increased significantly in the past 30 years. The main reasons are intensive monoculture and the use of non-specific insecticides. Secondly, due to the short growth time of one generation of mites, they can quickly develop resist...
