...knows how phloem necrosis spreads. Dutch elm disease is better understood; it is a fungus carried from elm to elm by small bark beetles. They slip through the meshes of the strictest quarantine. Spraying will kill them, and the Department is experimenting with DDT and its rival, benzene hexachloride ("Gammexane" in Britain; TIME, June 24). But it is not too hopeful. There are too many elms to spray...
Best hope for the future: resistant varieties. Siberian elms are not killed by Dutch elm disease-which probably indicates that the fungus came originally from Asia. The Buisman elm of The Netherlands is resistant also. The Department is already experimenting with fungus-defying hybrids. Perhaps, in a century, there will be an elm renaissance...

But after the black year 1935, when 85,000,000 bushels were lost to rust, Canada's Dominion Experimental Farms Service developed two "rustproof" wheat strains, Renown and Regent. Last week, the Service announced that rust, adapting itself to new conditions as Nature usually does, is now attacking the rustproof strains. But Canada's wheat crop was in little danger. Reason: the Service has developed...
...next few weeks 6,000 huskies, sent out by lumber companies and forestry services, will take to the woods, armed for total war. The enemy: white pine blister rust, an incurable fungus infection that is spreading like a blitzkrieg...
