Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiment:

[0013] 1) Scrape off the diseased tumors and old skin on the branches after the leaves fall in autumn, and then paint the scraped parts with 5Be lime sulfur mixture;

[0014] 2) Before germination in the next spring, paint the scraped part with 5Be lime sulfur mixture again;

[0015] 3) Spray Bordeaux mixture and 0.2Be lime sulfur mixture alternately after the apple fades. The interval between Bordeaux mixture and lime sulfur mixture is 15-20 days, and ends in early September;

[0016] The lime sulfur mixture is boiled from the following raw materials in parts by weight: 1 part of quicklime, 10 parts of sulfur and 100 parts of water.

[0017] The boiling method of lime sulfur mixture is as follows:

[0018] 1) Put 1Kg of quicklime powder into an iron pot, take a small amount of water from 100Kg of water to dissolve the quicklime, then add the remaining water and mix well; ...

Abstract

The invention discloses a method for controlling physalospora piricola nose of apple trees, belongs to the field of methods for controlling diseases of fruit trees, and aims to provides a method being convenient and easy to operate, low in cost, and good in disease resistance for controlling diseases of apple trees. The method includes scraping burls and old raised barks on a trunk after leaves fall in autumn, and coating 5 Be lime sulphur on scraped portions; coating 5Be lime sulphur on the scraped portions again in next spring; spraying a bordeaux mixture and 0.2 Be lime sulphur in an alternating mode after flowers on the apple trees fall until the first ten-day period of September, wherein the interval time between spraying of the bordeaux mixture and spraying of the 0.2 Be lime sulphur is 15 to 20 days. The lime sulphur is boiled by the following raw materials, by weight, 1 part of calcium oxide, 10 parts of sulphur and 100 parts of water. By using the method for controlling physalospora piricola nose of apple trees, diseases do not generate resistance, the effective rate of disease resistance and pest killing reaches up to approximately 90%. The invention provides the method for controlling physalospora piricola nose of apple trees.

Description

technical field [0001] The invention relates to a method for preventing and controlling fruit tree diseases, in particular to a method for preventing and controlling apple tree ring spot. Background technique [0002] Apple ring spot can damage all levels of branches and fruits of apple trees. On the branches, at the beginning of the disease, reddish-brown lesions are formed with the lenticels as the center. Later, the lesions protrude in the middle and become tumor-like, with cracked edges and upturned saddle-shaped. After many lesions are connected, the epidermis of the branches appears very rough, so it is also called rough skin disease. On fruit, the disease begins near maturity, is severe at harvest, and continues during storage. The typical symptom on the fruit is the formation of nearly round brown lesions centered on the lenticels, which may cause fruit rot in severe cases. [0003] Apple tree is a high-incidence tree species of ring spot, which will bring huge ec...
