Controlling wasps without insecticides
(H. Buchler)
While the wasp populations in most vineyards were lower than last year, some of the very early, thin-skinned varietals still suffered some damage. The culprits belong to the family of vespidae, with the European paper wasp appearing in the largest numbers, followed by the yellow jackets and the bald faced hornets.

Nutritional requirements for maintenance of healthy vines and highest quality grapes
(Dr. Gerry Neilsen - PARC)
Recently, there have been reports of vines with poor vigour and weak growth, which may be a result of nutrient deficiency, compounded by overcropping. Low vigour can also be a consequence of excessive root damage, resulting from soil nematodes. This project will correlate vine nutrition and quality of grapes in a number of soils in the Okanagan/ Simlkameen and determine if nematodes play a role in vines showing poor vigour.
