SUMMARY Of the list of possible remedies the following are the least desirable for using on a large scale for the reasons stated. Nicotine Uncertain in its action and being poisonous must be used cautiously. Pyridine Highly offensive odour. Petroleum Inflammable. Bugs dislike it, they often leave the pots and under certain conditions they may escape death. Methyl alcohol Inflammable, action slow. Acetone Will not mix with water—injections into the soil are impracticable. Fuel oil Bugs escape from the pots. Miscible fusel oil No effect. The three following stand out as being the most effective and suitable: Tetrachlorethane (Westoran) Trichlorethylene (Westropol) Potassium sulpho‐carbonate The root mealy bug and root aphis living under similar conditions in pots, adopting similar methods of feeding and protection, respond similarly to any particular treatment. The grower may, therefore, cope with both pests by the application of a common remedy.
