【摘要】 荸荠枯萎病是荸荠的一种毁灭性病害。研究结果表明,该病由尖孢镰刀菌(Fusarium oxysporum f.sp.eleocharidis)为害所致。病原菌生长和产孢温度范围10～35℃,适宜温度为25～30℃;pH范围在2～12,适宜pH为6.0～8.5。适宜的湿度、营养能促进孢子萌发。该病在福建省9月下旬至10月下旬为发生盛期,发病与种荠、流动水、温度、湿度等有关。挑选出室内抑菌效果较好的25%施保克、荸荠秆枯净进一步进行大田小区试验,防效分别为73.17%、60.49%。更多还原

【Abstract】 Fusarium Wilt is a destructive disease in Chinese water chestnut.The results showed the pathogen was Fusarium oxysporum f.sp. eleocharidis.The range of temperature for colony growth and conidial production was 10—35℃,with an optimum of 25～30℃. The range of pH was 2～12,with an optimum of pH6.0～8.5.The conidia can germinate well in optimum humidity and nutrition. The explosive phase of the disease in Fujian was from the last ten days of September to the last ten days of October in the year. The disease development is related to seeds, fluid-water, temperature, humidity and so on. The experiments showed that 25% Sporkle and Gankujing could control the disease effectively in the field.更多还原
