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.

Except cellulose acetate fiber,the strength of other four-kind fibers in completely dry state is decreased notably after MHT.With the initial moisture regain increased,the breaking elongations of cotton,rayon and loycell are improved remarkably after MHT.The increasing level is rayon>loycell>cotton,but ramie seems little improved.As the moisture regain is low,the fiber initial modulus is enhanced.However,when the moisture regain is higher,the fiber initial modulus did not change obviously.
除了醋酸纤维素纤维,其余四种纤维在初始回潮率为0的时候,经过微波处理,纤维强度都是显著性下降的:随着初始回潮率的增大,棉纤维、粘胶、天丝的断裂伸长率有了显著性的提高,其中升高的幅度为粘胶>天丝>棉纤维,苎麻没有显著性提高;在回潮率较小的范围内,微波处理之后纤维的初始模量是增大的,随着回潮率的增大,初始模量变化不显著。
