Embodiment 1

[0020] A method for preventing and treating pear scab, comprising the following steps:

[0021] (1) Select disease-resistant varieties: when building a garden, choose July crispy pears, Xiangshui pears, Western pears or sand pears with strong disease resistance;

[0022] (2) Eliminate the source of overwintering bacteria: clean up fallen leaves and fruits in late autumn and early winter, and burn them in a centralized way; pruning pear trees in early spring before germination, removing diseased shoots, reducing the source of infection, and spraying biological agents, the biological agent is 1.2μg / g Crude extract of bitter bark vine;

[0023] (3) Artificial prevention and control: timely search and cut off diseased shoots, diseased leaves and diseased fruits from April to May each year, and then bury or burn them;

[0024] (4) Strengthen cultivation and management: increase the application of organic fertilizers, enhance tree vigor, and improve tree disease resistance;

Embodiment 3

[0034] A method for preventing and treating pear scab, comprising the following steps:

[0035] (1) Select disease-resistant varieties: when building a garden, choose July crispy pears, Xiangshui pears, Western pears or sand pears with strong disease resistance;

[0036] (2) Eliminate the source of overwintering bacteria: clean up fallen leaves and fruits in late autumn and early winter, and burn them intensively; prune pear trees in early spring before germination, remove diseased shoots, reduce infection sources, and spray biological agents at 1.5 μg / g Crude extract of bitter bark vine;

[0037] (3) Artificial prevention and control: timely search and cut off diseased shoots, diseased leaves and diseased fruits from April to May each year, and then bury or burn them;

[0038] (4) Strengthen cultivation and management: apply more organic fertilizers to enhance tree vigor and improve tree disease resistance;

Abstract

The invention discloses a control method for scab of pears. The method comprises the following steps: selecting to use a disease-resistant variety, including selecting a variety which is relatively good in disease resistance in garden building; eliminating over-wintering pathogen sources, including sweeping fallen leaves and dropped fruits when autumn changes into winter, and burning the fallen leaves and dropped fruits in a concentrated manner; before pear trees sprout in early spring, combined with trimming, removing diseased shoots, to reduce infection sources, and spraying a biological drug; controlling in an artificial manner, including searching and cutting off the diseased shoots, diseased leaves, and diseased fruits in time in April to May each year, deeply burying or burning the diseased shoots, diseased leaves, and diseased fruits; enhancing planting management, including additionally applying an organic fertilizer to enhance tree vigor and improve tree disease resistance; controlling by drugs, including determining types and spraying frequency of drugs according to different growing periods and disease conditions. Through the above method, the method uses a comprehensive control measure, and control effect on scab is substantial, and loss caused by the scab is reduced.

Description

technical field [0001] The invention relates to the field of pear tree planting, in particular to a method for preventing and treating pear scab. Background technique [0002] Pear is a commercial fruit second only to apple in our province. The cultivated area is nearly one million mu, and a large-scale industry has been formed. But along with the gradual expansion of pear planting scale in recent years, several main diseases such as pear scab, rot and rust in the pear planting process have become increasingly serious to the production of pear fruit, seriously affecting the production of pear fruit. The quality and appearance pose a great threat to the pear industry in our province. Scab is one of the main diseases in the production of pear trees. It occurs more commonly and often causes heavy losses in severe years. In recent years, due to the uncontrolled use of fungicides and the continuous repeated use of a single agent, the resistance of pear scab has increased signif...
