[0035] Step 1: Preparation of ozonated sunflower oil

[0036] Select the DR03-A ozone machine (power≦55W) designed and produced by Xi’an Derun Biotechnology Co., Ltd., take 5L of commercially available Fulinmen sunflower oil and put it into a plastic bucket with a volume of 25L, and put the ozone machine catheter into In sunflower oil, make ozone gas fully react with sunflower oil, after continuous treatment for 24 hours, measure the IP value of ozonated sunflower oil to be 680mmol Kg -1 , the viscosity is 240mpa, the acid value is 40U, and the iodine value is 74. The prepared ozonated sunflower oil was refrigerated in the dark at 4°C for later use.

[0037] Step 2: Control cucumber powdery mildew in the greenhouse

Abstract

The invention discloses a method for preventing and controlling fungal diseases of cucumbers. The method comprises the steps of firstly inserting an ozone generator conduit into a container containing plant oil, introducing ozone for continuous treatment and performing saturation ozonization on the plant oil; adding a surfactant into the plant oil processed by the ozone and diluting and uniformly stirring with 10-100 times volume of water to prepare into an oil emulsion, and spraying the oil emulsion onto plant faces of cultivation soil of plants. The method for preventing fungal diseases of the cucumbers can ensure the durability of medical effect and can realize the controllability on use concentration. Experiments show that the sterilization effect of the method is not lower than the currently universal chemical fungicides such as carbendazim and procymidone, and the method has no side effects on plants, is simple and convenient to apply, and has the broad spectrum killing effect on harmful pathogenic microorganisms such as various funguses and germs beyond comparison with organic chemical pesticides.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a method for preventing and treating fungal diseases of cucumbers. Background technique [0002] my country is a major producer of horticultural products in the world, and the output of fruits and vegetables ranks among the top in the world. However, crop production reduction due to infection of plant diseases has been very serious, accounting for nearly one-third of the total output, and the economic loss is huge. For a long time, the control of plant diseases has mainly relied on the use of chemical pesticides. However, chemical fungicides have problems such as poor efficacy and large residues. Excessive abuse leads to environmental pollution, excessive pesticide residues, and quality decline. These problems are deteriorating day by day, which has a serious impact on my country's food safety and agricultural development. Therefore, the demand for non-toxic...
