Aphids Comments
APHIDS: Characteristics and Controls They feed on buds and flowers, are common on cymbidiums; winged forms can reinfest continually so systemic insecticides which last a month are preferred; use dimethoate (Cygon), Meta-systox and Temik. AH4; use Malathion, N329; in Florida, two kinds named, seven controls listed, DK10+, S190; use Meta-Systox-R, or Zectran, C73-22; OR74-227; OR74-230 0

APHIDS: Controls A common aerosol insecticide spray is satisfactory; use Raid and stand back several feet from plants to be most effective; don11 use a commercial insect repellant because they damage buds and flowers. RMH; A85-99Malathion, Diazinon, Cygon, Parathions are used for controls in Hawaii. P69(l)-llOrthene WP is recommended.
