摘要
分别于2016年和2017年,采用林业施药试验测定了不同稀释倍数的30%苯甲·丙环唑乳油、32.5%苯甲·嘧菌酯悬浮剂、40%腈菌唑可湿性粉剂等9种不同农药对山核桃干腐病病斑复发和新病斑形成的影响,比较了凿破病斑和不凿破病斑对喷药的防治效果。结果表明:供试的9种药剂对山核桃干腐病病斑复发及新病斑发生均有显著的抑制效果;凿破病斑处理能显著提高药剂防治效果,2016年,30%苯甲·丙环唑乳油和50%喹啉铜可湿性粉剂防治后病斑复发率分别降低了57.52%和61.14%,新病斑发生率分别降低了36.19%和34.75%;2017年,处理后均无病斑复发和新病斑产生。
Nine kinds of pesticides, including 30% difenoconazole · propiconazole EC, 32？ 5% difenoconazole ·azoxystrobin SC, 40% myclobutanil WP, 50% copper 8-hydroxyquinolinate WP, 36% copper 8-hydroxyquinolinat ·tebuconazole SE, 1.6% benziothiazolinone EC , 30% difenoconazole SE, 25% Difenoconazole WG and 75% TrifloxystrobinTebuconazole WG were used to investigate their control efficiency against Chinese hickory （Carya cathayensis） stem cankercaused by Botryosphaeria dothidea in the field. From 2016 to 2017, the ratios of both canker recovery and new canker occurrence decreased significantly after their application. In the meantime, 30% difenoconazole·propiconazole EC and 50%copper 8？hydroxyquinolinate WP were selected to assess the synergistic control effect after canker smashing treatment. In2016, comparing to the control, the ratio of canker recovery of 30% difenoconazole·propiconazole EC and 50% copper 8-hydroxyquinolinate WP decreased by 57.52% and 61.14%, respectively, and the ratio of new canker occurrence decreasedby 36.19% and 34.75%, respectively. In 2017, there were no more canker recovery and new canker.
