Spraying

These damn beetles are annoying as hell! I had to skip an insecticide application last week due to a flat tire on the tractor. Browning Equipment came and picked it up so I figured while they had it they may as well do a complete tune up: New rear tire, replaced several worn hydraulic hoses, all new filters and fluids. They did a great job but I was without the tractor for over a week. Missing one application of insecticide was all they needed to move back in. The damage is minimal (maybe 2-3 leaves on 50% of the vines) but it's the principle! So I put the sprayer back on the tractor and added the insecticide. And since we're into the humid summer season our consultant recommended we spray for both powdery and downy mildew as well.

For the powdery mildew we use Microthiol Special (wettable sulfur) at a rate of 4 lbs per acre. For the downy mildew we use Dithane DF Rainshield Nt (active ingredient is Mancozeb) at the same rate.
