摘要
梨锈病是为害梨树的一种真菌性病害。近年来,随着柏类树木种植的急剧增加及农药的不合理使用等因素,该病害在太原市梨主产区发病程度逐年加重,严重影响梨果的品质和产量。2023年太原市4月份降水量较常年同期偏多,极利于该病的发生,预计2023年太原市梨锈病中等发生,局部偏重发生,希望广大果农注意早期预防。
Fruit tree rust is a fungal disease that damages fruit trees.In recent years,with the rapid increase in cypress planting and the unreasonable use of pesticides,the disease has become increasingly prevalent in the main fruit producing areas of Taiyuan,seriously affecting the quality and yield of the fruit.Moreover,the precipitation in April this year in our city is 50%higher than the same period in previous years,which is extremely conducive to the occurrence of this disease.It is expected that fruit tree rust will occur moderately in Taiyuan in 2023,with some areas being more severe,and the growers should pay more attention to early prevention.
