After a lot of work by a number of people the Thrips Management Program for Plants for Planting is now available. This plan is an evolving document and will change as new information regarding thrips management is developed.
This document presents a program to manage thrips including but not limited to Western Flower Thrips (Frankliniella occidentalis) and Chilli Thrips (Scirtothrips dorsalis) on plants. This program does not require a pesticide application when the first thrips is detected. However, it does outline steps to manage and maintain thrips populations throughout the initial propagation and active growth stages at levels to enable complete control on final plant material being shipped. Growers should apply pesticides when scouting reports identify population densities at levels where experience and/or extension personnel dictate action be taken. These densities would depend on many factors including the crop, source(s) of infestation, history of viral infection, and environmental conditions
