稻瘟病是我县水稻上的主要病害,造成一定程度的损失,尤其是早稻损失程度更为严重。为了探求简便、有效的防治方法,1989年我们用三环唑药液浸秧苗,是防治稻瘟病的新的用药方法。据我们试验:浸过药液的秧苗种到大田后,比对照不浸的,叶瘟发生时间要推迟,丛发病率减少61.16％,叶片发病率减少71.64％,叶瘟中急性叶瘟所占比例减少49.64％。由于减轻了叶瘟,穗瘟也相应减轻。试验结果表明:处理区比对照区:穗病率减少66.11％,病情指数减少65.77％,损失率减少
Rice blast is the main disease on rice in our county, resulting in a certain degree of loss, especially the loss of early rice is more serious. In order to explore a simple and effective method of prevention and treatment, in 1989 we tricyclazole solution dip seedlings, is the prevention and treatment of blast of the new drug method. According to our experiments, after the seedlings of the soaking liquid were applied to the field, the time of leaf blast was delayed compared with that of the control. The incidence of plexus was reduced by 61.16% and the incidence of leaves was reduced by 71.64%. The acute leaf blast accounted for The proportion decreased by 49.64%. As a result of reducing leaf blast, panicle blast also reduced accordingly. The results showed that the treatment area was 66.11% less than the control area, the disease index was reduced by 65.77% and the loss rate was decreased
