CHEMICAL CONTROL OF ADELGES PICEAE (HOMOPTERA: ADELGIDAE) IN NEWFOUNDLAND, 1967

Abstract Five insecticides (Baygon, diazinon, Dursban, Furadan, and menazon), previously shown to have some effect on control of the balsam woolly aphid, Adelges piceae (Ratz.), on branches of Abies balsamea (L.) Mill., have been tested more intensively. Individual trees were sprayed from the ground...

Description
Summary:Abstract Five insecticides (Baygon, diazinon, Dursban, Furadan, and menazon), previously shown to have some effect on control of the balsam woolly aphid, Adelges piceae (Ratz.), on branches of Abies balsamea (L.) Mill., have been tested more intensively. Individual trees were sprayed from the ground with 1.0, 0.5, or 0.25 litre of solution containing 5% active ingredient (an approximate per acre dosage rate of 12 to 25 lb). Dursban, Baygon, and diazinon caused 85, 75, and 72% mortality respectively. Furadan and menazon were less effective, causing 56 and 34% mortality.
