近年来,省外各地试验证明,通过秧田药剂防治可以推迟本田期病害发生期和减轻病害的危害。我省罗甸地区中稻秧苗已有发病,晚稻秧苗普遍发病。因此,秧田用药就更为重要。据74年用噬菌体检验法测定和田间調查,凡是中、晚稻秧苗带菌量高或秧苗已发病的移栽本田后,发病早为害重,凡是中、晚稻秧苗带菌量少或秧苗未发病的移栽
In recent years, tests at various places across the province have proved that it is possible to postpone the occurrence of diseases in Honda period and lessen the harm of disease through the control of seedling agent. The rice seedlings in Luodian area of our province have been inoculated, and the incidence of late rice seedlings is common. Therefore, seedling medication is even more important. According to the 74 years of phage assay and field surveys, usually in late rice seedlings with high transplanting Honda or seedling disease, the incidence of early damaging, usually late rice seedlings with less transplanting or seedling disease
