摘要
通过田间试验,研究了40%琥胶肥酸铜.三环唑可湿性粉剂防治水稻稻瘟病的效果。结果表明,采用40%琥胶肥酸铜.三环唑可湿性粉剂400倍液,在水稻孕穗期、破口期和齐穗期施药,对叶瘟和穗颈瘟防治效果分别达到80.86%和87.87%,增产率可达19.37%,对水稻生长无不良影响。
The effect of 40%DT ＋ Tricyclazole WP germicide was evaluated against rice blast in field trials in Guangdong Province. The results showed that 40% DT ＋ Tricyclazole WP had good effects on controlling rice blast Ustilaginoidea virens （Cke.） Tak.. The controlling effects were 80.86% to leaf blasts and 87.87% to neck blasts of rice with 400x, when the pesticide sprayed at boot stage, breaking hole and full heading time.
