今年南方大部分香蕉在7～8月份抽蕾,以吸芽蕉居多,抽蕾挂果期正是高温多雨季节,抽蕾后病虫发生扩展快且危害严重,主要表现为香蕉抽蕾后,植株抗病力下降,加上长期单一地使用某种杀菌剂,使得病菌已产生抗性,容易引发叶斑病、折叶型叶柄炭疽病、蕉果黑星病和纹孔病(又叫梅毒病)等;主要发生的虫害有香蕉叶跳甲和花蓟马。针对这一状况,香蕉抽蕾后在病虫防治上应主要把握好两点:1.选准药剂。因蕉农长期单一地使用某种杀菌剂,病菌已产生抗性,应考虑换用其它特效药,例如“应得”(内吸、 This year most of the southern bananas in July and August to bud, in order to absorb the majority of bud banana, pumping buds fruiting period is the high temperature and rainy season, after pumping buds spread rapidly and serious harm, mainly for the banana bud, the plant Resistance to decline, coupled with the long-term use of a single fungicide, making the bacteria have resistance, easily lead to leaf spot, foliar petioles anthracnose, banana fruit scab and psoraleae (also known as syphilis ); The main pests are banana leafhopper and flower thrips. In view of this situation, the banana buds in the prevention and control of pests should be mainly to grasp the two points: 1.
