Natural Mildew Spray Treatment


During the lunch break at last Sunday's Bee keeping workshop the folks enjoyed a walk around the main vegetable garden here at Jembella.  When Brian was asked about controlling mildew he told of the Casuarina  (Equisetum) Tea that he brews from needles of Casuarina or commonly referred to as Sheoak and sprays out to treat mildew on our vegetables. It is also very good for grape vines.


 When asked the mixing rate, Brian admitted that he now goes by sight, and he promised to consult our Biodynamic Manual and let them know. Our original copy of this resource manual became so well used it almost fell apart, so I purchased another copy from Bio-dynamics Agriculture Australia to keep in the house for my use.

 So here is the recipe for Fresh Equisetum or Casuarina Tea as described in the manual.
Cover fresh leaves (needles) from the Casuarina, Equisetum) Tree with water and bring to the boil. Simmer for twenty to thirty minutes and allow to stand until cool.
Strain off the liquid (tea) and use to the ratio of 10 litres of tea to 400 litres of water @ 34 litres per hectare.
It should be poured into a bucket or drum and stirred for twenty minutes before pouring into your spray unit or container. Those already familiar with bio-dynamics will understand the necessity of stirring, to potentize or energise, the preparations before spraying out in the early morning or late afternoon. 
The tea will keep for up to three weeks in a capped container in a cool dark place. When it starts to get black and a bit smelly, throw it away and brew up a new batch.

Depending on the area you need to spray, it can be put out using anything from a small spray bottle to a large mechanised spray unit behind a tractor.
It's amazing stuff, cheap to make, and harmless to our plants, the beneficial insects in the garden and ultimately, ourselves!
Cheers!

  2. Thanks for that recipe, Sally. I don't think we have that tree here unfortunately. I will have to ask my husband about that.
