Grass and weeds need not be removed from around the base of the tree before applying the chemical. 2. Heavy rains just before or just after treatment do not appear to effect the action of the gas. 3. One year trees have not been injured when treated with P. D. E., in the proper manner. 4. It is not necessary to remove dirt from around the trees after treatment. 5. Up to the present time, there have been no injurious cumulative effects of P. D. B., in Illinois. 6. P. D.
