Can anyone help me with info on what I should buy to use. thanks. From peter cundalls page http://www.abc.net.au/gardening/stories/s1631445.htm Bordeaux Mixtu 1 Dissolve 100 gram of builders’ (hydrated) lime in half a standard (plastic) bucket of water. (About 5 litres). 2 Dissolve 100 grams copper sulphate (available at garden centres) in a separate half bucket of water. 3 Keeping the lime mixture agitated to prevent settling, pour it steadily into the half bucket of dissolved copper sulphate. 4 If necessary add enough extra water to make up a total of 10 litres. This is Bordeaux mixture. It is at its most effective strength when freshly mixed so must be used immediately or within a couple of days. 5 It is sprayed to completely cover the main (bare) branches of peach, nectarine and other stone fruit trees to help control leaf curl and brown rot disease. It is also sprayed over raspberry canes in late July for control of raspberry rust. Bordeaux mixture colours the sprayed plants blue. The spray can withstand light rain. However a disadvantage with this mixture is that it tends to quickly settle so must be constantly agitated during spraying operations. The lime content also tends to easily block the fine nozzles of sprayers. Burgundy Mixtu This is virtually the same except that lime is replaced by washing soda (cheaply available at supermarkets in 1kg packets as a water softener). The amounts are the same, as is the method of mixing. Always use non-metal buckets – standard 10 litre plastic buckets are ideal. If the water is slightly warm the washing soda and the copper sulphate dissolve more rapidly. Slowly pour half a bucket of (100 grams) dissolved washing soda into half a bucket of (100 grams) dissolved copper sulphate and add more water if necessary to make up 10 litres. The advantage of Burgundy mixture is that it does not block sprayer nozzles. It is also a little stronger and must never be used on plants in leaf.

Would suggest extreme caution with the washing soda though, as its vey alkaline and can burn. http://www.cutofcloth.com/article_bakingsoda.asp As well, dont confuse lime with Builders lime which is different to other lime... Know what you are using.... |

Washing Soda
which supermarket have you tried norman?
google hits aplenty, aussie ones suggest it's in the supermarket near the laundry detergents. washing soda = sodium carbonate. pulled this off the web: Can you tell me where I could buy washing soda? I have tried a number of big supermarkets, and a big hardware chain, but with no success. Thanks. You'll find washing soda in the cleaning aisle of your supermarket. It's in a smallish clear plastic bag in either a crystal or powder form. The brand name is Lectric Soda. It's generally around the pre-wash, ironing aid area. Most supermarkets have it, it's just usually well hidden.
