Q.What Quantity Of Water Do I Require To Mix 10g Of Miedzian 50wp?
I have an apple tree in my garden it usually produces a large amount of fruit but this year very little fruit it has something which is creeping up the trunk making the bark peel off. I read in a gardening book that miedzian could be the answer so I orderd some off the internet but the instructions are not in English. I would be grateful for your advice. many thanks

This is very hard to dose out in such small quantities. This is more geared towards large fields, but generally, 1-4 percent is recommended.
The lower end of that should be used during fruiting, but you can treat with a higher concentration during dormant seasons.
Figuring out concentration rates should be done in Liters. This will make life much easier. 4 percent of 1000 ml (1L) will be 40 mL, and so on.
