Carbofuran, oxamyl, aldicarb and fenamiphos treatments were tested for control of grape phylloxera [Daktulosphaira vitifolii (Fitch)] on ungrafted Cabernet Sauvignon grapevines in central Victoria. All insecticides were applied as granular formulations to the root zone of grapevines. Oxamyl was also tested as a foliar spray. Carbofuran was the most effective treatment, although aldicarb and oxamyl reduced phylloxera populations at some sampling periods. Fenamiphos did not control phylloxera. Vegetative growth, yield and root mass of infested grapevines declined during the 3 years of the experiment. In the third year, carbofuran- treated vines had significantly (P=0.05) greater fruit yield and more vegetative growth than control vines, but were performing poorly in relation to yields expected from uninfested vines. It is concluded that carbofuran treatment combined with optimum viticultural management may delay or reduce the decline of phylloxera infested grapevines. However, replanting with vines grafted to resistant rootstocks is a preferable long-term solution.

Strategies that mitigate the negative effects of vineyard exposure to smoke on wine composition and sensory properties are needed to address the recurring incidence of bushfires in or near wine regions. Recent research demonstrated the potential for post-harvest ozonation of moderately smoke-exposed grapes to reduce both the concentration of smoke taint marker compounds (i.e., volatile phenols and their glycosides) and the perceived intensity of smoke taint in wine, depending on the dose and duration of ozone treatment. The current study further evaluated the efficacy of ozonation as a method for the amelioration of smoke taint in wine by comparing the chemical and sensory consequences of post-harvest ozonation (at 1 ppm for 24 h) of Cabernet Sauvignon grapes following grapevine exposure to dense smoke, i.e., ozone treatment of more heavily tainted grapes. Ozonation again yielded significant reductions in the concentration of free and glycosylated volatile phenols—up to 25% and 30%, respectively. However, although the intensities of smoke-related sensory attributes were generally lower in wines made with smoke-exposed grapes that were ozonated (compared to wines made with smoke-exposed grapes that were not ozonated), the results were not statistically significant. This suggests that the efficacy of ozone treatment depends on the extent to which grapes have been tainted by smoke.

Vegetative growth, orchard productivity, fruit quality and marketable yield were evaluated for rootstock (D6, BP1 and Quince A), tree density (741–4444 trees/ha), and training system (Open Tatura trellis, two-dimensional vertical and three-dimensional traditional) effects on young trees of the blush pear cultivar ‘ANP-0131’. ‘ANP-0131’ is a vigorous scion and vegetative growth, precocity, and yield were influenced by the selected rootstocks. Tree density and training system treatments exerted a substantial effect on canopy radiation interception while increasing tree density improved yield. Increasing tree density from 2222 (high density) to 4444 (ultra-high density) trees/ha did not improve cumulative yield. Crop load affected fruit size, such that “marketable” yield (yield of fruit weighing between 150 and 260 g) was greatest for trees on D6 rootstock and trained to Open Tatura trellis at high and ultra-high densities.
