Management

Due to the recent introduction of chilli thrips into the U.S., pest management programs are still being developed. Preliminary tests suggest that foliar sprays with insecticides containing acephate, imidacloprid, or spinosad are effective for pest control on ornamental landscape plants (Table 2). The use of insecticides containing pyrethroids (such as bifenthrin, cyfluthrin and permethrin) is not recommended because they are not very effective against chilli thrips, and are more damaging to beneficial insects.

Note: Pesticides labeled for landscape plants should not generally be used on vegetables, unless specifically noted on the label. Failing to follow pesticide labels carefully is illegal and can result in unsafe applications. Under certain temperature, humidity, water and shade conditions, pesticides may cause injury to certain plants (phytotoxicity). Generally, apply pesticides during early morning to avoid dew or late afternoon to avoid the hottest part of the day. Water plants 1-2 days before applying a pesticide. Always check the product label for the list of plants that may be injured by the pesticide.
