Embodiment 1

[0029] Weigh gallnut, the stems, leaves, roots or mixtures of gallnuts, ghost needle grass, ground brocade, and thistle, and the discarded stems, leaves, flowers, fruits, or their mixtures of acacia and linden trees that have been pruned or naturally fallen off, and dried Grind into powder (20 mesh particles) each 25g, impregnate 3d at room temperature with 125ml of 70% ethanol solution, filter, get the filtrate of four kinds of plants and concentrate under reduced pressure to recover the solvent to obtain the extraction extract (wherein Galla galla extract accounts for 20%, ghost 20% needle grass extract, 30% brocade extract, 10% thistle extract, 10% albizia juniper extract, 10% linden tree extract). Then add 20% Tween, stir according to conventional technology, make it mix evenly, make compound plant fungicide. Then it is diluted with water to be prepared as a compound plant fungicide whose concentration of crude drug is 1.7%. The indoor pot method of the compound plant fun...

[0032] Weigh gallnut, the stems, leaves, roots or mixtures of gallnuts, ghost needle grass, ground brocade, and thistle, and the discarded stems, leaves, flowers, fruits, or their mixtures of acacia and linden trees that have been pruned or naturally fallen off, and dried Grind into powder (20 mesh particles) each 80g, soak 7d at room temperature with 2000ml of 15% methanol solution, filter, get the filtrate and concentrate under reduced pressure to recover the solvent to obtain the extraction extract (wherein Galla galla extract accounts for 38%, ghost needle grass 7% extract, 15% Kamba extract, 30% thistle extract, 8% Albizia Julibrissin extract, 2% linden tree extract), and then 30% Tween, stirred according to the conventional process to make it evenly mixed, Made into a compound plant fungicide. Then it is diluted with water to prepare a compound plant fungicide whose concentration of crude drug is 4%. For cucumber downy mildew, the indoor potting method was used for biot...

Embodiment 3

[0034]Weigh gallnut, the stems, leaves, roots or mixtures of gallnuts, ghost needle grass, ground brocade, and thistle, and the discarded stems, leaves, flowers, fruits, or their mixtures of acacia and linden trees that have been pruned or naturally fallen off, and dried Grind into powder (20 mesh particles) each 45g, impregnate 1d at room temperature with 1500ml of 30% ethyl acetate solution, filter, get the filtrate and concentrate under reduced pressure to recover the solvent to obtain the extraction extract (wherein Galla galla extract accounts for 6%, ghost 39% of needle grass extract, 7% of brocade extract, 3% of thistle extract, 29% of albizia juniper extract, 16% of linden tree extract), and then add a certain amount of conventional auxiliary materials according to the conventional process to make a compound plant sterilization agent. Then it is diluted with water to be prepared into a compound plant fungicide whose concentration of crude drug is 0.9%. For cucumber do...

Abstract

The invention provides a compound plant bactericide containing Rhus chinensis Mill., and preparation and applications thereof. The compound plant bactericide is composed of, by weight, 40 to 80% of a bulk pharmaceutical chemical and 20 to 60% of a conventional auxiliary material; the bulk pharmaceutical chemical comprises, by weight, 5 to 40% of Rhus chinensis Mill. extract, 5 to 40% of Bidens pilosa L. extract, 2 to 30% of Cirsium setosum extract, 2 to 30% of Tilia tuan Szyszyl. extract, 2 to 30% of Albizia julibrissin Durazz. extract, and 2 to 30% of Parthenocissus tricuspidata extract. The compound plant bactericide is prepared from natural plant extracts, can be decomposed easily under natural conditions, is safe to the environment and the surrounding ecological system, and is a pollution-free plant-derived biological bactericide; and no environmental pollution is caused.

Description

technical field [0001] The invention relates to a plant fungicide in the technical field of pesticides, in particular to a compound plant fungicide containing gallnut and its preparation and application. Background technique [0002] Pesticides play an important role in controlling agricultural pests and increasing agricultural production and income. In order to improve the quality of human living environment and food quality, countries all over the world are conducting research on reducing the amount of chemical pesticides. Pollution, high biological activity, high selectivity biological pesticide. Among them, finding substances with antibacterial activity from plants has become an important way to create new fungicides. In addition, the random discarding of a large number of agricultural wastes today not only causes a lot of resources to be idle and wasted, but also causes a certain burden on the environment. Therefore, to realize the recycling of agricultural waste reso...
