hey all,
I did my first spray with bayern I think its called last week, it says complete every 10 days for a maximum of 4 times.

my question is if i do this then I am finished spraying in the first half of July, will this really protect the potatoes for remainder of july and into august

I am wondering does the spray only work for 10 days or does it build up ammunity over the 4 sprays to last the season

hoping someone can advice
thanks

I use bluestone and washing soda. It was the original solution to blight.

No idea I'm afraid, but it sounds fierce complicated. I don't use any sprays. I grow blight resistant varieties and cut off the foliage as soon as I see signs of blight. Lots of blight last year but the tubers were plentiful and healthy.
