Abstract

The invention provides a prevention and treatment method of alternaria leaf spot of potted apple trees, and belongs to the field of fruit tree pest control. The prevention and treatment method comprises the following steps: 1, Chinese herbal medicine raw material pretreatment; 2, potted apple tree seedling root-soaking treatment; 3, cultivation soil preparation; 4, transplanting; and 5, watering. The prevention and treatment method has the beneficial technical effects that the occurrence of the alternaria leaf spot of the potted apple trees is greatly reduced, the pathogenic bacteria drug resistance degree of the alternaria leaf spot of the potted apple trees is reduced.

Description

technical field [0001] The invention belongs to the field of prevention and control of fruit tree diseases and insect pests, and in particular relates to a method for preventing and treating potted apple tree spot defoliation disease. Background technique [0002] The taste of apples is delicious and delicious, and it is one of the fruits that are often eaten in daily life. Its peel is smooth and brightly colored. In addition to being edible, it can also be used as a bonsai. As a bonsai apple mainly for ornamental purposes, it has dwarfing tree body, thick roots, short branches, small leaves, large and colorful fruits, late maturity, easy flowering and early fruiting, high fruit setting rate and self-pollination rate, It has the characteristics of strong disease resistance and ability to adapt to the potted environment. [0003] Due to fine management, good ventilation and light transmission, potted apples grow vigorously and have fewer pests and diseases. Once pests and d...
