提起金银花，我们首先想到的就是它是一味良好的药材，实际上金银花还是园林绿化的好材料，将其修剪成球状，点缀在草坪上，可爱又俏皮。今天我们来谈一下金银花的病虫害及其防治。

金银花的虫害及其防治

常见害虫：胡萝卜微管蚜

消灭虫卵可以很好的减少虫害，喷洒3-5波美度石硫合剂，可以有效的杀死虫卵。为了防止虫害的迁移，可在早春时喷10%吡虫啉可湿性颗粒2000倍液，或者1%印楝素剂800倍液。

常见害虫：榆木角线蠹蛾

榆木角线蠹蛾具有趋光性，因此，可以借助这一特点，安装黑光灯进行诱杀。还可以选择在植株的根部喷洒浇灌杀虫剂进行消灭。

金银花的病害及其防治

金银花的病害多为真菌感染所致，因此，在日常护理中，应不断加强水肥管理，注意植株的修剪工作。发现褐斑病时，可以每周喷洒一次65%代森锌可视性颗粒600倍液，连续喷洒三到四周，就可以得到有效的控制。

发现白粉病时，可选取75%百菌清可湿性颗粒1000倍液，每周喷洒一次，连续喷洒三到四次，就可以及时的抑制住病情了。

要控制煤污病的发生，首先要控制好蚜虫的危害，其次，选取75%甲基托布津可湿性颗粒1000倍液防治，同样每七天一次，连续喷洒三到四次。
