ACP Effective Insecticides
See individual pesticide labels and the UC IPM guidelines for citrus for rate recommendations. Many insecticides are effective in killing psyllids, especially if they make direct contact.
Synthetic Insecticides known to be effective for ACP management. The broad spectrum insecticides have a much longer residual than the soft insecticides - often weeks to months. Of these insecticides, the neonicotinoids and pyrethroids have the greatest persistence and so the greatest effect on populations. Research is demonstrating that Actara (foliar thiamethoxam) is a particularly effective insecticide. *Insecticides that affect primarily egg and nymph stages.
Organic insecticides provide short-term reduction of ACP
Organic insecticides require direct contact with the insect body and so it is difficult to control the hard-to-reach nymphal stages of ACP with these products. The persistence of organic products is only hours-days (not weeks like the synthetics) and so they need to be applied frequently. Of the organic insecticides tested, Entrust shows the greatest efficacy and persistence. Treatment frequency: For each conventional insecticide application, apply two organic treatments 10-14 days apart.
