preparation example Construction

[0046] The preparation method of the plant immune inducer in the following examples adopts the conventional pesticide preparation method, that is, after mixing and dissolving each component in water, the cucumber immune inducer of the present invention is obtained.

[0047] 1. Test materials

[0048] The cucumber variety is 'Jinchun 4'.

[0049] 2. Administration of immune inducers

[0050] The test was carried out in the Binjiang Experimental Base of Hangzhou Plant Protection Soil and Fertilizer General Station. The seedling substrate is vegetable garden soil: peat: charcoal ash (12:15:23), and add appropriate amount of compound fertilizer.

[0051] 9 treatments are set in the test, wherein, comparative example 1 (contrast 1) is clear water solution contrast, comparative example 2 (contrast 2) is carbendazim, and each process is repeated 3 times, and each repetition is 1 plot, and each plot is 100 seed.

[0052] The concrete application method of immune inducer is: (embod...

Abstract

The invention discloses application of a plant immune resistance inducer in prevention and control of damping-off and blight of cucumbers. The plant immune resistance inducer is prepared from the following active ingredients in percentage by weight: 0.001 to 0.025 percent of amino-oligosaccharin, 0.01 to 0.25 percent of phosphite and 0.01 to 0.25 percent of phosphate. Each component of the immune resistance inducer obtained by combining the amino-oligosaccharin, the phosphite and the phosphate is mixed in a reasonable proportion, so that a good prevention and control effect on damping-off and blight of the cucumbers can be achieved, an emergence rate and a seedling rate of the cucumbers can be increased, and seedling quality of the cucumbers can be improved.

Description

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to the application of a plant immune inducer in the prevention and treatment of cucumber damping-off and blight. Background technique [0002] Cucumber suffers from a variety of pathogenic bacteria during the whole growth process, among which damping-off and blight are the main diseases of cucumber seedlings in winter and spring. [0003] Most of the pathogens causing cucumber damping-off are melon and fruit rot mold (Pythiumaphanidermatum (Eds.) Fitzp), belonging to the flagellate subdivision fungus; mycelia cotton flocculent, white, mycelium without septum, diameter 2.3 ~ 7.1 μm; sporangia filamentous, size (63 ~ 725) μm × ( 4.9~14.8) μm; ovary organ spherical, diameter 14.9~34.8 μm. egg spore Spherical, smooth, 14.0-22.0 μm in diameter. [0004] The pathogen is very saprophytic and can survive in the soil for a long time, overwintering on the diseased plant res...
