It belongs to the chloronicotynl class of insecticides. Although, Ni-25 is noted for its activity towards whiteflies and aphids it has demonstrated some activity to thrips. Success has demonstrated good activity against a broad range of Lepidopterous pests, leafminers and thrips. Like Alert, it has translaminar activity and will move into the leaf tissue, and is most active after ingestion. It is thought to act at the GABA site and also at the nicotinic receptor on the nerve synapse.
Success is very safe to beneficial insects and is low in toxicity to mammals.
The purpose of this research was to evaluate the efficacy new insecticides and insecticide currently available for citrus thrips control, for their potential for use in the unique growing conditions of the low desert citrus production areas of Arizona. The following report represents citrus thrips control data collected during 1997 from three separate small plot efficacy trials. Materials and Methods Nine year old lemon trees managed by Glen Curtis Inc. in Yuma, AZ were treated with insecticides for control of in three separate efficacy trials during 1997. All small plot tests were randomized complete block designs consisting of four replicates. Temperature data are presented as an average maximum daily temperature in F for each 24 hr period following the most recent insecticide application.
