Spraying freshly grafted apples/pears

General Fruit Growing

I am going to try my hand at grafting this year and had a question about spraying freshly grafter trees. My area is prone to cedar apple rust and fireblight. Would it be ok spraying the grafted trees with neem oil and em-1 (the recipe Michael Philips uses but can’t recall other ingredients at the moment)?

If it matters I plan on sealing the graft union with Parafilm and the tip with wax.

Yes.

You should know BTW that CAR is just going to laugh at those sprays. It needs something stronger. Or just leave it be, the trees will look bad but usually the fruit is not so damaged. Quince rust on the other hand can seriously damage the fruit.
