Aim at the influence factors about special field, cultivation system and cultivating level of rice in Shanghai farm, I studied characters of rice stripe blight occurrence on the Farm, investigated the disease resistance level and yield lose rate of different rice cultivars planted on the Farm, and made the suggestion about a synthetical control strategy for the disease in priority to adopt rice cultivars with resistance to the disease. Through investigation for the actuality of plant protection in Shanghai Farm and the examination of medicament for the disease, I gave an advice about the best chemical controlling method for the disease.

本研究的目的和方向：针对上海农场这一特殊地域因素、栽培制度、种植水平等因素的影响来研究农场水稻条纹叶枯病的发生特点；通过调查与试验上海农场不同品种的抗病性及产量损失，从而提出推广抗病品种的防治策略；通过调查与试验上海农场栽培制度下条纹叶枯病的发生特点，从而根据上海农场的特点提出综合防治的策略；通过对上海农场现有植保状况的调查与药剂试验，从而提出最佳化学防治方法。

Rice stripe blight occur only bits and pieces and didnt result in obvious harm from 2001 to 2003, and quantity of Laodelphax striatellus Fallen was very low and only in part place it was more serious.

And the lesion number of severest diseased stem is over 100, the percentage of disease in Brown Spot is around 60%. From the result of fungicide test, we know the Difolatan, Benlate and Orthocide are the more effective for controlling Stem Blight, but the percentage of prevention don't reach the perfect effect. The effect of other fungicides is not good. So we must continue to work to search for safe, and ideal fungicides as the index of prevention.

由药剂试验结果，以Difolatan（预防率：100p.p.m为80.95%，200p.p.m为83.33%），Benlate（预防率：100p.p.m为85.71%，200p.p.m为92.85%），Orthocide（预防率：100p.p.m为71.42%，200p.p.m为73.80%），三种药剂对茎枯病之防治效果最佳，但预防率未达百分之百，其他药剂之防治效果不佳，故仍需进一步寻求安全、有效之防治药剂，以供今后笋农防治茎枯病之依据。
