【摘要】 辣木果腐病是辣木种植业上的重要病害之一,其病原菌为半裸镰刀菌Fusarium semitectum Berk & Rav.。辣木果腐病为季节性动态流行,一般发生在4～7月辣木果荚生长至成熟期;5月中下旬是3月份坐果的果荚果腐病流行速度最快的时期,4月下旬至5月下旬是4～5月份坐果的嫩荚果腐病快速流行期,整个流行过程流行速度因时而异。雨水是导致辣木果腐病流行的主要环境因素,降雨量、降雨时间是关键因子。辣木果腐病易感期为伸长生长期,是防治的关键时期。辣木果腐病的防治应在4月中旬开始进行,与防虫相结合,并清除田间杂草。更多还原

【Abstract】 Fruit rot which caused by Fusarium semitectum Berk & Rav.is one of the important diseases on moringa oleigera.It occurs generally during fruit growth period from April to July,it develops rapidly in the late of May on March fruits and is usually in late April to May on young fruits of that time.The epidemics is influenced by some factors in which the rain is the main factor,the rainfall and raining time are key factors.The elongation period,which was susceptible to fruit rot,is the key control time as well.So it was the best time to control during disease occurring from the middle of April,combined with insect and weed control in the field.更多还原
