植物图片 2021-02-27 11:00

锈病是它经常出现的病害，可以每隔半个月的时间喷粉锈宁溶液。黑斑病也是其一，梅雨时节常见，可以喷洒多菌灵溶液防治。如果出现白粉病，情况严重可直接将叶片剪掉，喷洒抗霉菌素溶液。虫害方面也比较严重，红蜘蛛和蚜虫是最经常见到的，喷氧化乐果乳剂的溶液。

一、病害方面

1、锈病：感染的初期，叶片上会出现黄褐色的小斑点，如果不及时处理的话，后期斑点会越长越大，最终影响生长。可以每隔半个月的时间喷粉锈宁溶液，或者是敌锈钠溶液，一般喷几次就能治疗好。

2、黑斑病：刚开始的时候，叶片的中间部分会出现黑褐色的小斑点，后期逐渐感染影响整个叶片，一般在梅雨时节常见。可以喷一些多菌灵，治疗效果也是不错的，这个病情不能拖延。

3、白粉病：症状是叶片上会出现白色的粉末斑点，会感染其他的叶片。需及时将白粉清除掉，情况严重的话可直接将叶片剪掉，植株上喷洒一点抗霉菌素溶液，隔半个月喷一次。

4、其他病害：除了上述的这几种之外，还可能出现霜煤病、花叶病等，需先将叶片剪掉，之后喷洒药剂。

二、虫害方面

虫害方面也是比较严重，红蜘蛛和蚜虫这两种非常常见，是危害它的主要害虫，可以先人工去除，或是配制一些自制的农药，要是数量非常的多喷氧化乐果乳剂的溶液，可以起到很好的效果。
