室内研究了“嘧菌酯+恶醚唑”对西瓜枯萎病菌和西瓜炭疽病菌菌丝生长和孢子萌芽的抑制效果,结果表明:嘧菌酯与恶醚唑以1∶2混配时,混剂对病菌菌丝生长和孢子萌芽菌具有显著的抑制作用。田间试验研究了“嘧菌酯+恶醚唑”对西瓜枯萎病和西瓜炭疽病的防治作用,结果表明:嘧菌酯与恶醚唑以1∶2混配时,混剂对西瓜炭疽病和枯萎病具有良好的防治效果。同时,混剂可以明显提高西瓜的含糖量、Vc含量、可溶性固形物含量。
The inhibitory effects of azoxystrobin and oxapazole on mycelial growth and spore germination of Fusarium oxysporum and watermelon germplasm were studied in laboratory. The results showed that when azoxystrobin and oxazole were mixed in a ratio of 1: 2, Mixture of the mycelial growth of bacteria and spore germ has a significant inhibitory effect. The field experiment was conducted to study the control effect of azoxystrobin and oxapazole on watermelon fusarium wilt and watermelon anthracnose. The results showed that the mixture of azoxystrobin and oxazole was mixed with 1: 2, Disease and blight have a good control effect. At the same time, the mixture can significantly improve the watermelon sugar content, Vc content, soluble solids content.
