Tropical and Sub-Tropical Quarantines

Authors: Wilmon Newell;

Tropical and Sub-Tropical Quarantines

Abstract

Quarantines to prevent the introduction of insect pests and plant diseases from foreign countries are of prime importance. The southern states are more vitally concerned with quarantine protection than are the northern states as insects have, in the South, a large number of host plants and control measures must be applied during a longer growing season. The Federal Horticultural Board is the mainstay of the country in the maintenance of effective quarantines and while its work has been invaluable and its accomplishments significant it is still far short of what it should be. Education of the public as to the importance of quarantine protection and more liberal appropriations for the work of the Federal Horticultural Board are urged.
