BT and Pyrethrin which first?

[brogro]

I've got spider mites which I want the pyrethrin for, and I've got BT for the bud worms. Which would you spray first, would you wait days in between. Do you guys use a light soap as a surfactant with the BT. Will it kill them?

Thanks

Not sure if BT will kill mites (information on the internet is conflicting). BT has to be ingested by the bug, and it is not systemic, so it has a limited effect on sucking insects like mites and thrips. Pyrethin will kill them both, but I would not spray it if the plant is in flower. Pyrethrin is best sprayed at lights out, as it can burn leaves. If you've got mites, I'd spray for them first (you may have to do it twice, about a week apart). Then let the plant recover a bit and do the BT. BT won't burn the plant, unless it has an oil or soap added to it.

Those 2 will tank mix fine, at lower application rate.

In flower, might want to use spinosad or Grandevo on mites which also tank mixes with Bt-k.
Pistils are fragile, so higher application rates may brown them. Grandevo defenitly will.
Another option is following up pesticide spray with B.bassiana mixed in the Bt-k. It will weaken survivors, infect hatchlings for the second application.

I use couple tablespoons of Regalia for sufactant in flower, seems to help the plant recover faster.

Nice, is regalia a fungicide as I see on line?

Bio stimulant, produces an immune response in the plant.
Plants will fight off Powdery Mildew better, when applied before you have a problem with it.

Mix in some DE as well, it doesn't kill the infestation, but it will slow it down.

Is there a cheaper way to do regalia or is the expensive option the only way? Is there a way to not pay “retail”?, i guess is what im askin
