| 柑橘黑点病(Diaporthe citri)是危害柑橘最严重的病害之一,每年需要喷施4-5次杀菌剂进行防治,为明确68.75%噁酮.锰锌WG对柑橘果实黑点病的防治效果,分别在浙江黄岩和常山进行了田间试验。结果发现黄岩试验点68.75%噁酮.锰锌WG 500倍全程5次对黑点病的防治效果为84.79%、常山试验点同样药剂800倍全程4次对黑点病的防治效果为74.10%,效果不亚于常规推荐的杀菌剂代森锰锌,说明68.75%噁酮.锰锌WG 500-800倍在柑橘花谢2/3后开始第一次用药,隔20-25天喷施一次,共用药4-5次,可有效防治柑橘黑点病。 |

| Citrus melanose caused by Diaporthe citri Sis one of the most serious diseases affecting citrus marketability and requires spraying of fungicides 4-5 times a year for control, Field tests were conducted in Huangyan and Changshan, Zhejiang province, to determine the effect of 68.75% mancozeb.famoxadone WG on citrus melanose. Our experiments showed that the prevention effect of 68.75% mancozeb.famoxadone WG 500 times, 5 sprays during fruit growing season for melanose was 84.79% at Huangyan test site , and 68.75% mancozeb.famoxadone WG 800 times for melanose was 74.10% at Changshan test site, the effect were similar to those of the conventional recommended fungicide mancozeb. The results showed that 68.75% mancozeb.famoxadone WG 500-800 times was used for the first time after 2/3 of the citrus flower faded, and then sprayed once every 20-25 days for a total of 4-5 times could effectively prevent and control citrus melanose. |
