Embodiment 1

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

[0023] The leaves of moso bamboo are cleaned and placed in the room to air-dry, pulverized with an electric grinder, and passed through a 40-mesh sieve to obtain moso bamboo leaf powder. Weigh 500g of moso bamboo leaf powder into the extraction tank of the extraction and concentration unit, add 10L of 95% ethanol at a ratio of 20:1 (extraction solvent / sample, ml / g), extract at an extraction temperature of 30°C for 2 hours, repeat twice, and concentrate the extract The prepared Phyllostachys pubescens extract into extract form, and stored at 4°C.

[0024] Preparation of 10% Moso Bamboo Extract Water Emulsion

[0025] Configure according to the formula shown in Table 2, the configuration steps are as follows:

[0026] (1) Uniformly mix the moso bamboo extract, organic solvent and emulsifier into an oil phase;

[0027] (2) Evenly mix antifreeze, thickener and distilled water to form a water phase;

Abstract

The invention relates to a moso bamboo extract emulsion in water and a preparation method thereof, belonging to the technical field of bactericides. The moso bamboo extract emulsion in water contains the following ingredients by weight: 5-15% of moso bamboo extract, 10-30% of organic solvent, 5-20% of emulsifier, 2-5% of antifreeze agent, 0.1-3% of thickener and the balance of water. The moso bamboo extract emulsion in water provided by the invention meets the requirements of pesticide formulations on quality and has good effecs in inhibiting plant pathogenic bacteria. The moso bamboo extract emulsion in water has the advantages that the raw material are readily available, the processing is simple, the cost is reduced, and the moso bamboo extract emulsion in water is environmentally safe and has bacteriostasis activity; and the moso bamboo extract emulsion in water is a botanical pesticide.

Description

technical field [0001] The invention belongs to the technical field of fungicides, and in particular relates to a moso bamboo extract fungicide aqueous emulsion preparation and a preparation method thereof, which are applied to tomato gray mold, tomato fusarium wilt, pepper gray mold, tomato leaf mold, and rape sclerotinia Prevention and control of fruit and vegetable diseases such as apple anthracnose and pear scab. 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 environmental safety, extensive plant resources, safety to non-target organisms, specific mode of action, and high efficiency to target organisms. [0003] Phyllostachys pubescens extract is obtained by extracting...
