As soon as the tree fruit management guides are done being formatted they will be posted to our website and I will let you know when they are available. In the meantime, this article will highlight the key changes that you can expect to see in this year's guides.
When the guides become available, all modifications mentioned below will be coloured red directly in the text for easy reference. Discard old editions of the pesticide spray guide publication each year.
