Hi Sherwin

I have the book 'the fruit tree expert' by Dr d.g. Hessayon and on page 50 there is a title called Spraying programs in which it tells you to use these chemicals to prevent the following, apple blossom weevil, canker, scab, capsid bug and many more diseases.
It does say to dilute the stuff though. There is nothing wrong with my trees but I thought that it would benifit them.
If it eliminates the mother in law too thats a definite bonus!! lol!

Do you have any other ideas on prevention of tree diseases?

Thanks

Richard
