Systemics Comments
SYSTEMICS: For Scale Control Systemic sprays are not very effective because orchids grow too slowly to get a good "burst" of pesticide into the affected area; Cygon is the best for Boisduval scale but is not labelled for greenhouse use. A87-615 0
SYSTEMICS: Insecticides Commercial names include Actidione, Cygon 2E (Dimethoate), Di-Syston, Orthene, Meta-Systox-R, Temik. RMHOf limited effectiveness because orchids grow slowly and systemics are not much good, although Cygon 2E will penetrate the sheath of cattleyas and kill scale, etc. ; it takes months for a systemic to move from the roots to the top of the plant. A87-615; OIE85Jy-6 0
SYSTEMICS: Pesticides A product that has been recommended for years in Florida is Meta Systox-R25.4%. A87-1237 0
SYSTEMICS: Review For description, etc. of Di-Syston granules, Di-Syston cartridge, Meta-Systox-R sprays and Cygon spray, refer to C69-46+ see also Cygon 2E; Insecticides; Temik 0
