Riverland people are not known for their boastfulness; certainly not in their vineyards and wineries. Community is a key word. Helping each other out, encouraging new ideas, finding ways to do more with less. These are values that mark the majority who choose to live and work here. Winegrowers in the Riverland are incredibly privileged to have among their numbers, gifted viticulturists, prepared to share their knowledge and expertise as a core element of the comeback; back from a decade of drought and dreary grape and wine prices that would break most spirits. But not these:
People of the region like Nicole Pitman from Kingston Estates, Pete Arnold from Treasury Estates and Ian MacRae from CCW, all contribute way beyond what might normally be expected restore pride, professionalism and profitability to our vineyards. Nicole has provided the following reminders for this week:
Some varieties of wine grapes are nearing stage 19 (i.e. start of flowering). Growers should ensure thorough coverage is achieved and should consider the use of a DMI (e.g. Domark ® or Topas ®) just before, or during the early part of flowering. If growers have had a problem in the past consider, using a strobilurin (e.g., Flint ® Amistar®, or Cabrio ®), Flute®, or Vivando® as a way of rotating chemical groups in your spray program. Be aware that the larger canopies may mean that more water volume and slower ground speeds are needed to achieve adequate spray coverage. This may be different from the calibration that was used at similar times last season. Growers are urged to constantly check the performance of their spray units and make sure that coverage is adequate.
The first botrytis preventative sprays should commence during flowering in susceptible varieties (e.g. Chardonnay, Colombard and Semillon) where growers decide sprays are needed
Now is the time to start monitoring for light brown apple moth. Look in bunches and shoot tips for webbing and caterpillars, and on leaves for egg masses. There have been large numbers caught in pheromone traps recently. This year could possibly be a year for high light brown apple moth pressure.
Thanks Nic. Next week we’ll have some tips from Pete Arnold.
