Embodiment Construction

[0023] (1) Strengthen cultivation management. Control the fertilizer and water, do not apply nitrogen fertilizer, do not make the garden soil too dry, and thin the flowers and leaves reasonably.

[0024] (2) Eliminate primary infection sources: insist on cleaning orchards and nurseries every autumn, plan tree trays, plow tree rows, eradicate self-rooting tillers and wild seedlings, and burn diseased plants, fruits and leaves. Timely and thorough removal is required.

[0025] (3) Chemical control: use biological pesticide control made of Chinese herbal medicine, weigh 190 grams of Chinese herbal medicine Dafengzi, 190 grams of Chuanxiong, 260 grams of Digupi, 260 grams of Psoralen, and 260 grams of Eucalyptus eucalyptus leaves, pulverize them and put them in an airtight container Add an appropriate amount of ethanol, cover and impregnate, stir, and after standing for 5 days, pour out the supernatant; add an appropriate amount of 50% to 75% ethanol to the medicinal residue, impr...

Abstract

The invention discloses a method for biological control of hawthorn powdery mildew, which comprises the steps that (1) cultivation management is strengthened, wherein fertilizers and water are controlled, excessive applying of a nitrogen fertilizer is avoided, garden soil is avoided from becoming too dry, and thinning of flowers and leaves is carried out rationally; (2) initial infection sources are removed, wherein an orchard and a nursery garden are cleaned in each autumn of a year, tree disks are dug, ploughing is carried out between tree rows, self-rooting tillers and wild seedlings are eradicated, sick plants and sick fruits are burnt, and sick leaves are timely removed thoroughly as required; and (3) chemical control is carried out, wherein a bio-pesticide made of Chinese herbal medicines including Hydnocarpus anthelmintica, Ligusticum wallichii, cortex lycii radicis, fructus psoraleae and Eucalyptus robusta leaf is sprayed. A field trial shows that the method is effective in prevention and control, leads to no pesticide residue and is environment-friendly and green.

Description

technical field [0001] The invention relates to a method for preventing and controlling plant diseases, in particular to a method for biologically controlling hawthorn powdery mildew. Background technique [0002] Combining the biological knowledge of middle school, the applicant carefully observed the powdery mildew of hawthorn planted in his own hawthorn garden in accordance with the requirements of the high school biological practice class, trying to reveal the law of its occurrence and development, and using my country's rich resources of Chinese herbal medicine to develop The biological control test, the test results prove that the biological control not only has a remarkable effect, but also has no pesticide residues, which is environmentally friendly and safe. [0003] When the leaves of hawthorn powdery mildew are infected, white powdery spots will appear on both sides of the leaves. In severe cases, the white powder will cover the entire leaves, and small black dots ...
