两种无机铜剂对桔全爪螨种群的影响

Effects of two copper fungicides on population of Panonychus citri (McGregor)

通过室内、室外药效实验,测定了波尔多液和王铜对桔全爪螨种群数量的影响,研究了2种无机铜剂对桔全爪螨的刺激作用。结果表明,施用波尔多液会明显刺激桔全爪螨发生;而施用王铜区虫口密度与对照区差异不显著。因此,王铜可以替代波尔多液在柑桔园使用。

Effects of Bordeaux mixture and copper oxychloride on population of Panonychus citri （McGregor） were studied by laboratory and field experiment to investigate the stimulation of two copper fungicides to P. citri. Results showed that Bordeaux mixture can stimulate the occurrence of P. citri, but copper oxychloride had no significant difference with CK. Copper oxychloride can replace Bordeaux mixture to control Xanthomonas campestris pv. citri （Hasse） Dye in orange garden.
