Problems solved by technology

[0006] From the fall of leaves in winter to the spring of the next year, the germs and overwintering eggs will be revived. Simple cleaning of fallen leaves in the garden can only remove some of the eggs, but it cannot effectively kill the germs. After the temperature warms up, the bacteria will infect the crabapple again, resulting in slow growth of the crabapple
[0007] In the process of preventing diseases and insect pests on the crabapple, the influence of bacteria on the crabapple is usually ignored. Due to the poor disease resistance of the crabapple, the growth of the crabapple will be slowed down by the action of bacteria, resulting in the death of the crabapple.

Embodiment 1

[0026] A method for preventing and treating the brown spot disease of Begonia chinensis comprises the following steps:

[0027] step one:

[0028] Spring: April is the first month when the flowers of the crabapple are in full bloom. Due to the end of insect dormancy and the growth of pathogens, the crabapple will be eroded. Prevent it once in the first ten days of April, and use protective fungicides, because The increase of rain in spring will wash away the pesticides sprayed on the crabapple and reduce the efficacy of protective fungicides. Therefore, after that, prevent once every 20-30 days, and then use therapeutic fungicides later.

[0029] According to the life cycle of aphids, before April 15, combined with the control of aphid pupae 80% mancozeb wettable powder 600 times liquid control, mancozeb wettable powder can kill aphids, so that the aphid pupae will not affect the hanging silk The crabapple is affected. Since April is the flowering period of the crabapple, the...

Abstract

The invention discloses a method for preventing and controlling brown spot of malus halliana and solves the problem that malus halliana suffers from brown spot and bacterial damage. The method is characterized by including the following steps: in spring, preventing for one time in early April, namely, mainly using protective bactericide and subsequently using curative bactericide, using a 750-multiple solution of 75% chlorothalonil wettable powder for prevention and control in middle May, and using a 700-multiple solution of 70% thiophanate-methyl wettable powder for prevention and control from late May to early June; in summer, using a 3000-multiple solution of 43% tebuconazole suspension for prevention and control from late June to early July, and using a 1000-multiple solution of 25% prochloraz rubber oil for prevention and control from late July to early August. The method has the advantages that prevention and control can be realized according to degree of plant disease and insect pests in different mouths, so that growing speed of malus halliana is increased.

Description

technical field [0001] The invention relates to the technical field of plant disease and insect pest control, and specifically belongs to a method for preventing and treating the brown spot disease of begonias. Background technique [0002] Suisi crabapple is a plant of the genus Malus in the Rosaceae family, and it is a unique plant in China. Hanging silk crabapple likes sunshine, not tolerant to shade, and not very cold-resistant. It likes warm and humid environment, suitable for growing in sunny and leeward places. The soil requirements are not strict, and it can grow in slightly acidic or slightly alkaline soil. The growth is better with deep, loose, fertile, well-drained and slightly sticky layers. This peanut is strong in nature, easy to cultivate, and does not require special technical management, but it is not resistant to waterlogging. Potted plants must be protected from waterlogging to avoid root rot. Distributed in Sichuan, Anhui, Shaanxi, Jiangsu, Zhejiang, Y...
