Introductory note. Further investiga tional work has shown that methyl bro mide fumigation in partial vacuum can be applied at lower soil temperatures than heretofore authorized, for the de struction of larvae of the white-fringed beetles; also, that larvae of all species of white-fringed beetles can be included under the same treatment schedules.
Dosage schedules for fumigation o f nur sery plants with soil balls not greater than 5 inches in diameter under nor mal atmospheric pressure have also been developed. Likewise fumigation sched ules for produce have been developed.
