| Authors: | A. Kvåle, B. Hovland |
| Abstract:
In 1993 a survey of pesticide use in Norwegian apple orchards was undertaken. A total of 1250 growers were asked to report on the usage of pesticides in the orchards. In 242 (85%) of a total of 283 orchards the number of insecticide sprays ranged from 1 to 4. Except for dimethoate, dosages applied per ha ranged from 15 to 58 percent of maximum recommended dosage. Number of fungicide sprays ranged from 5 to 8 in 72 percent of a total of 286 orchards. Dosages of fungicides applied per ha ranged from 19 to 74 percent of maximum recommended dosage. | |
