用叶枯净、代森铵防治稻苗白叶枯病,因期残效其短、不耐冲刷又无内吸性,加之病菌来源广,侵染期长,故需多次施药才能取得较好的效果。我们试验了敌枯双对稻苗化学免疫的作用,结果表明它内吸性强、残效期长、内疗作用好,能抑制叶内病菌的增殖和运行,降低发病率,减轻严重度,使发 With leaf dry net, the generation of ammonium prevention and control of rice seedling blight, due to its short residual effect, impatience flushing and no internal absorption, combined with wide source of bacteria, the infection period is long, so the need for multiple application in order to get more Good results. We tested the enemy dry double pairs of chemical immunization of rice seedlings, the results showed that it has strong systemic absorption, long residual period, good effect of internal medicine, can inhibit the proliferation and operation of leaf pathogens, reduce the incidence and reduce the severity of hair
