preparation example Construction

[0028] 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 grape immune inducer of the present invention is obtained.

[0029] 1. Test materials

[0030] Grape variety 'Yongyou No. 1' (Yinzhou District Forestry Bureau, Zhejiang Province).

[0031] 2. Administration of immune inducers

[0032] Beginning in early April 2014, the grape production base in Hengjie Village, Jincheng Street, Lin'an, sprayed once every half a month, and ended in late July, with a total of 6 sprays. For each treatment in the base, two rows (23 grapes in each row) were selected to spray the corresponding chemicals. For each treatment, 10 grapes were randomly selected for statistics and related indicators. A total of 30 grapes were selected for three repetitions. Other field management measures such as fertilizer and water management were the same during the tes...

Abstract

The invention discloses application of a plant-immunity resistance inducer to the prevention of grape downy mildew and anthracnose. The plant-immunity resistance inducer comprises the following effective components in percentage by weight: 0.001-0.02 percent of amino oligosaccharin and 0.01-0.2 percent of phosphite. According to the application, the amino oligosaccharin and the phosphite are combined, the mixing ratio of all the components of the obtained plant-immunity resistance inducer is reasonable, the prevention effect on the downy mildew and the anthracnose is good by applying the plant-immunity resistance inducer to grape, and the yield and the quality of the grape 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 grape downy mildew and anthracnose. Background technique [0002] Grapes suffer from a variety of pathogenic bacteria during the whole growth process, among which grape downy mildew, grape anthracnose, and grape white rot are the most common. [0003] Grape peronospora belongs to the flagellate subphylum, Oomycetes Peronospora order, Plasmodium genus. Grape downy mildew survives the winter in the diseased tissue as oospores, or remains in the soil with the diseased leaves. In the next year, under suitable conditions, oospores germinate to produce sporangia, and then zoospores are produced from the sporangia, spread by wind and rain, invade from the stomata on the back of leaves, and carry out initial infection. Through the incubation period of 7-12 days, sporangia and sporangia are produc...
