I appreciate the consistent disdain for spraying fungicides and insecticides but at this point in time, spraying is THE option.
As far as sarcastically spraying 4 times a year, 50 bpa x 4 will pencil very nicely but 2 will most likely be sufficient. It’s not something to be reactive to, it’s not a scout and spray when you see it, you have to be proactive about it. It’s pretty easy to see who has dealt with it before and who hasn’t. Just happens to be a much bigger classroom than normal this year.
I don’t know. Hopefully someone did some extensive testing this year. Based on color alone even some very late 1 time sprayed looks a lot different. I’m betting it could have been scouted and treated while it was in the lower leaves and still payed off |
