Embodiment 1

[0028] The dried cumin roots, stems, leaves and seeds are crushed and passed through a 40-mesh sieve. Weigh 100kg of crushed cumin in a reflux extraction kettle, then add 400kg of hexyl acetate solution, conduct reflux extraction at a temperature of 70°C to 80°C for 8 hours, and filter to obtain the extract. Concentrate the extract to 100kg to obtain the cumin extract. Embodiment 2: the preparation of cumin antiseptic cream

Embodiment 2

[0029] Weigh 50 kg of cumin extract, dissolve it with 40 kg of methanol, add 9 kg of nonylphenol polyoxyethylene ether and 1 kg of calcium dodecylbenzenesulfonate under stirring, and stir evenly to obtain 100 kg of cumin sterilized cream. Embodiment 3: the preparation of cumin antiseptic microemulsion

Embodiment 3

[0030] Weigh 30kg of cumin extract and 15kg of nonylphenol polyoxyethylene ether phosphate, dissolve in 15kg of ethanol, heat the above solution to 43°C in a homogenizer, and add 40kg of deionized water dropwise under high-speed stirring; After the addition is complete, stir for another 45 minutes and cool to obtain the cumin bactericidal microemulsion. Test Example 1: Determination of the inhibitory activity of cumin hexyl acetate extract to plant pathogenic bacteria
