Abstract
SUMMARY: A device is described which, fitted to conventional pruning shears, applied a small quantity of fungicide to the surfaces of pruning wounds on apple trees. Of a number of fungicides tested in conjunction with the shears plienylmercuric nitrate (PMN) was found to be the most effective protectant against subsequent infections by Nectria galligena. The data presented showed that both pruning early in the season and well above the bud reduced infection. Wounds became increasingly resistant to infection with age and very few lesions developed from inoculation of wounds 30 days old. The protestant action of PMN remained effective throughout this period.Keywords
