Embodiment 1

[0022] Embodiment 1: the preparation of Phyllostachys pubescens extract

[0023] Clean the leaves of Phyllostachys pubescens and place them to air-dry indoors, pulverize them with an electric pulverizer, and pass through a 40-mesh sieve to obtain leaf powder of Phyllostachys pubescens. Weigh 500 g of the leaf powder of Phyllostachys pubescens and put it in the extraction tank of the extraction and concentration unit, press 20:1 (extraction solvent / sample, ml / g) was added with 10L of 95% ethanol, extracted at an extraction temperature of 30°C for 2h, repeated twice, and the extract was concentrated to extract, and the prepared Phyllostachys pubescens extract was stored at 4°C.

Abstract

A fungicide compound preparation containing moso bamboo extract and a preparation method thereof belong to the field of fungicide technology. The preparation includes the following components: Moso bamboo extract 5-15%, kresoxim-methyl 0.1-3%, organic solvent 10-30%, emulsifier 5-20%, antifreeze agent 2-5%, thickener 0.1- 3%, water is the remainder, and each component is measured in parts by weight. The compound aqueous emulsion of moso bamboo extract and kresoxim-methyl provided by the invention meets the quality requirements of pesticide preparations and has good inhibitory effect on plant pathogenic bacteria. The invention has the advantages of easy-to-obtain raw materials, simple processing, low cost, environmental safety and antibacterial activity, and is a mixed agent of plant source extracts and chemical pesticides.

Description

technical field [0001] The invention belongs to the technical field of fungicides, in particular to a fungicide compound preparation containing moso bamboo extract and a preparation method thereof, which is applied to tomato leaf mold, tomato gray mold, pear scab, pepper gray mold, rapeseed Control of fruit and vegetable diseases such as sclerotinia, apple anthracnose and tomato wilt. technical background [0002] Environmental pollution and food safety caused by long-term use of traditional chemical pesticides have aroused widespread concern. In the process of crop pest control, there is an urgent need to use low-toxic, low-residue, and easily degradable pollution-free green pesticides. Botanical pesticides have the advantages of low toxicity to humans and animals, not easy to produce drug resistance, little or no residue, etc., but most of the natural fungicides currently developed have many disadvantages: the dosage is relatively large; and most natural product compounds...
