豆瓣绿的病虫害防治

Miss Chen

豆瓣绿的养殖环境要保持空气流通湿润,温度在10~30度之间,豆瓣绿喜阴,平时散光养护就可以,避免强光照射,豆瓣绿生长旺季生机勃勃,一片绿色。

1、环斑病:受害植株产生矮化,叶片扭曲。

防治方法:用等量式波尔多液喷洒。

2、根颈腐烂病、栓痂病

防治方法:用50%多菌灵可湿性粉剂1000倍液喷洒。

3、炭疽病:叶斑近圆形,褐色至灰褐色,边缘深褐色,病、健部分界明晰,后期斑面散生小黑点(病菌分孢盘),病斑易破裂,或脱落成穿孔。

防治方法:

①冬春清园,疏除过密荫枝及病残物,随即全面喷施1%波尔多液一次。

②发病期视天气和病情交替喷施30%氧氯化铜胶悬剂,或40%多硫悬浮剂,或30%混杀硫悬浮剂600~800倍液。

豆瓣绿病害较少,主要有环斑病毒病为害,受害植株产生矮化,叶片扭曲,可用等量式波尔多液喷洒。另有根颈腐烂病、栓痂病为害,用50%多菌灵可湿性粉剂1000倍液喷洒。

虫害偶有介壳虫和蛞蝓危害,要及时防治。
