Multiple Pests

[Leafmite]

Hi!
I was reading this and wondered how systemic is applied to orchids that are planted in an open media. I've had to treat other plants and I've always used a granular type that is mixed in the soil. So far, the pests prefer the other plants and alcohol has taken care of things with the orchids but I do want to be prepared. What type of systemic is used with orchids? How much? And, yes, if the nasties keep returning on that cymbidium, definitely go for the systemic. If these things really like your cymbidium, they can get out of hand very quickly.
Good luck,
