Of these respondents, 37 were also personally interviewed. Responding arborists combined purchased 9,200 pounds of fungicide and 225,000 pounds of insecticide in 1982. Benomyl, maneb, and zineb were the most frequently used fungicides; carbaryl, dimethoate, malathion, and dormant oil were the most frequently used insecticides. Scab and rust were the most prevalent diseases; scales, aphids, and bagworms were the most prevalent insects. Cost of pesticide purchased by the average Illinois arborist was $8,500. Of this, 15% was for fungicides and 85% for insecticides. ER -
