Chill requirements of new pear cultivars

Researchers are uncovering the chill requirements of new and old pear cultivars including ANP-0131 (Deliza®), ANP-0118 (Lanya®), ANP-0534, and PremP009 (Piqa®Boo®). In doing so they hope to understand the suitability of these cultivars for the Goulburn Valley now and under future climates. When selecting new varieties, growers consider many important factors including marketability, time to [...]

Effects of climate change on apple and pear production

Australia’s climate has warmed since 1910 and is likely to continue warming, with more hot days and fewer cold days expected in future, according to State of the Climate, 2016. So how will climate change affect apple and pear production in Australia? In some horticulture industries, like vegetables, decisions relating to new plantings such as [...]

Historical and future climates for Australian growing regions

Global temperatures have warmed in the past 100 years and this trend is likely to continue. What changes in climate can Australian growers expect in the future? Autumn and winter temperatures have increased in most apple and pear growing regions in Australia. Climate change refers to any long-term trends or shifts in climate [...]

Website shows winter chill data for your region

A new website ( is providing access to accurate local winter chill data for Australian apple and pear growers, with benefits for in-season orchard management and long-term orchard business planning. A new website helps growers to access and interpret local winter chill data to help with crop management for the current season, as well [...]

Tasmania calls for bumble bee trials to progress

Endemic populations of bumble bees in Tasmania could help to improve pollination services in the state if trials are allowed to progress, a Senate Inquiry hearing in Hobart was told in February 2017. Bumble bees could be used to pollinate Tasmania’s apple, pear and other horticultural crops. Overseas, Bombus terrestris (bumble bees) are [...]

Finding the triggers of biennial bearing in apples

Australian and German researchers from the Productivity, Irrigation, Pests and Soils (PIPS) program are embarking on a new project to better understand the underlying processes that cause biennial bearing in apples trees.  Understanding what causes floral bud development is fundamental to finding better ways to manage biennial bearing.  Biennial bearing is the term used [...]

Preparing for Varroa destructor

Plant Health Australia outlines how growers can prepare for an incursion of Varroa destructor that would seriously threaten bees and orchard pollination. Currently Australia has a high concentration of feral honey bee colonies (unmanaged hives in the wild) that help to pollinate many crops including apples and pears. But, as overseas experience has [...]

Dormancy-breaking sprays for low chill years

By Heidi Parkes, Susie Murphy-White and Sally Bound Researchers are assessing the value of dormancy-breaking sprays to help growers encourage compact and uniform flowering in their apple orchards when it’s just not cold enough for the trees to do it on their own.   The use of dormancy-breaking sprays could help apple and pear growers adapt to warmer years because dormancy breakers can stimulate earlier, more homogenous bud burst [...]
