The dreaded broad mites.. I feel for you bulldog I battled them last year... My recipe was as follows.... Use a strong dosage of a miticide called Nuke Em- the lady said it was designed to battle broad mites,
Avid and
Floramite,,, Mix these three miticides in a 30 gallon tote with water and soluble seaweed as well as cal mag and Caterpillar killer.... might as well spray for caterpillars at the same time and you can also use a wetting agent if you want.... Use one or two atomizers depending on the size of your garden and completely spray the shit out of everything every three days for about 2 weeks,,, wear masks and try not to get to much on your skin.... Yes i know how bad these pesticides are and I don't care-- Mites are 10 times worse..... It stopped the damage on the 15 that had it and prevented any spreading to near by plants.. I literally cried watching 8 or 9 foot beautiful plants start dying right in front of me.... Good luck
