| Abstract: | Melanpsors magnusiana of more than 20 clones of Populus euramericana during their secdling was investigated and results are as follows:Melanpsors magnusiana of 6 clones etc. such as L-B_1,and L-B_2 is rcla tivcly serious and pathogecnic indexes are all over 20%, L-B_1 is the highest and reachs 78.7% in which. Control effcct of 70% thiophanate-methyl on Melanpsors magnusiana is good and over 50%, and 800 times liquid of 70% thiophanatc-methyl is bcst and reachs 83.2% especialliy. |
