5200 |a"The investigations described in the following pages grew out of a request of the Department of Agriculture of Nova Scotia and of various horticultural organizations, that a study be undertaken to determine whether the alleged destruction of pollinating insects by poison dusts and sprays was adversely affecting the set of fruit in commercial apple orchards. As a result of the initial survey, the work quickly broadened out into a study of the entire pollination problem. As indicated in the evidence presented, it was found that the hive bees of the Annapolis valley had indeed suffered great losses as a result of prevailing spraying and dusting practices. However, it was found that wild solitary bees were sufficiently abundant in most orchards during the period of the investigation, alone to effect pollination under favourable conditions. The results secured emphasized that the proper interplantingof cross-fruitful varieties was a crucial factor in the production of commercial crops"--p. 5.
