Hi All,
I can no longer obtain Malathion WP and am looking for a replacement systemic insecticide in a wettable powder form. Wondering what thoughs you might have? What products you are using?
This is for use in a GH situation. For a collection of about 500 plants. Of which 90% are seedlings, ex vitro, ranging in age from about 2 years to last week.
Growing in/on various media; Sphagum moss, soilless mix, bark mixes, cork bark, and tree fern.
After about a 20 year hiatus from growing orchids, and now in our retirement, we (my bride, the fair Jacqueline and I) have started again. However, we are well behind the curve on the latest/best agents.
Understand nothing beats good culture as a preventative measure. But we are bringing also bringing in mature plants. Some of which arrive with minor amounts of "livestock" on board. While these had been kept in check where they can from, under new conditions and after the stress of shipping, we are getting occasional flushes of "undesirables".
Any thoughts, suggestions, ideas, experiences would be very appreciated.
Thanks in advance.
