Effects of crop load on apple fruit maturity

Fruit maturity at harvest plays a key role in quality. Dario Stefanelli, of Agriculture Victoria, outlines the results of trials into the effect of crop load on fruit maturity which form part of an international collaborative project to better understand biennial bearing. Apples are among the most important commercial fruit crops grown worldwide. Meeting market [...]

Growing a quality crop with limited water

With growers looking to set up their crop for the coming season with the possibility of limited water, AgFirst’s John Wilton explores ways to grow marketable crops in a dry year; methods that are also relevant if water is not an issue. High quality requires thinning to well-spaced singles. Matching crop load to [...]

Brevis secures Australian registration

The Adama-developed fruit thinner Brevis® has been registered for Australian use by the Australian Pesticides and Veterinary Medicines Authority (APVMA). Brevis is a secondary thinner for apples, containing the active constituent metamitron at 150 g/kg in a water soluble granular formulation, applied as a foliar spray. Welcoming the registration, Adama Australia said Brevis has been developed to [...]

Understanding Biennial Bearing in Apples – 2018 Update

Why do some apple cultivars bear biennially? Listen to Jens Wünsche, University of Hohenheim, Germany, and Dario Stefanelli, Agriculture Victoria, talk about recent progress in their Productivity, Irrigation, Pests and Soil (PIPS2) project Physiological, metabolic and molecular basis of biennial bearing in apple, and why international collaboration is great for industry.

Speed updating gives growers a fast serve of current R&D

In June, as part of Hort Connections 2018, APAL ran its annual Speed Updating event where industry researchers shared key information for growers about their findings. Funded by Hort Innovation as part of the Australian Apple and Pear Innovation and Adoption Program, this year’s Speed Updating was attended by more than 130 people. PIPS The [...]

Precision crop load management without chemicals

In the lead-up to spring, University of Tasmania researcher Sally Bound updates us with the latest and very promising results from her research identifying how to use Artificial Spur Extension to manage crop load and get better production results. What is Artificial Spur Extinction? Artificial Spur Extinction (ASE) is a crop load management method using [...]

Pushing orchard performance boundaries

AgFirst’s John Wilton hones in on some key factors – particularly chemical thinning in the lead up to spring – that orchardists can concentrate on to optimise yield and fruit colour.  In preparation for writing this article I spent some time trawling through our OrchardNet™ Australian database. The database shows that in general, Australian orchard yield performance is climbing. The two major varieties [...]

High orchard performance depends on good thinning

By John Wilton, AgFirst The 2014/15 season was a very good time for pome fruit across Australia. The positive results were partly due to a kinder than normal climate for growing apples but this appears to have been a minor factor.  These second leaf red strain of Cripps Pink have failed to colour well [...]

Spring crop management

By John Wilton This tree flowered for about six weeks. At the time the photo was taken the flowering sites ranged from tight cluster to early stages of petal fall. The chemical thinners lifted fruitlet rather than reduced it. As we head towards Spring, AgFirst’s John Wilton shares his advice and expert tips [...]
