Hello,
Does anybody know what the correct apllication rate is for this product: Immunox (2% Myclobutanil)?
When applying this product do you spray the top and bottom of the leaves or do a soil drench?
I am in western, PA when do you think the best time is to start applying fungicides?
How often do you apply this product?
Thanks in advance for the help!

Is this the one you have?

"Yes" you need to treat both sides of the leaves. Pay particular attention to the bottom

Yes, That is exactly it.
This is a systemic can the leaves absorb the the fungicide and take it into the plant, or does it just coat the leaves and deter the fungi from starting?
Thanks

Myclobutanil is a basipetal penetrant. A true systemic (acropetal penetrant) could be soil applied then found coursing up through the vascular system. Not so most fungicides. Only Aliette/Agri-fos/etc can truly translocate up & down.
Myclobutanil can only penetrate locally. It doesn't get all the way through a leaf even with the most advanced penetrating surfactants.
It coats the leaf & penetrates the cells on the treated side.
Contact fungicides protect a leaf only until the leaf outgrows the protective layer or until sunlight (& to a lesser extent rain) degrades the layer. Systemic fungicides have limited protective properties but they can kill a fungus after it has gained access to the plant.
No fungicide can do everything. Hence we find what works best for the problem we're dealing with at the time.
