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 [...]

Bud burst in ‘Williams’ pears highly variable

Bud burst in ‘Williams’ pears is highly variable, leading researchers to look deeper for the causes to find management strategies that support an even bud burst and even maturity of fruit for harvest. Author: Marco Calderon Masters Student University of Melbourne 0434 058 769 Evenly matured fruit at harvest time makes picking [...]

A discussion on dormancy — and why it’s worth thinking about in early December

By Dr Heidi Parkes Eight years ago I made the shift from Sydney to Stanthorpe, Queensland. One of the first things I noticed was how distinctly each year is broken into seasons by the apple trees that grow in the area – the dormant trees in the winter, the masses of blossoms in the spring, [...]

It’s blooming time for quality fruit

Regular readers of my blog — Farming Unlocked — will know that I do not particularly enjoy our cold winters. However as spring envelops us, the weather warms up and the sun’s rays soak into my skin and prise something open from within. My heart feels somehow warmer and I feel invigorated and alive. This is mirrored [...]
