Residential buffer zones around commercial citrus can be treated by CDFA with insecticides to suppress Asian citrus psyllid populations only if 90% of growers in that region apply insecticides within a designated 3-week window. While useful, this threshold created logistical difficulties and a new criterion for treatment was explored. We proposed that regions that reached 90% in 2 out of the last 3 treatment windows be eligible for buffer zone treatments.
