THRIPS PDF Print E-mail

Thrips continued to create headaches in greenhouses this week as normal control efforts have fallen flat. Products such as spinosad (e.g. Conserve), abamectin (e.g. Avid) and methiocarb (e.g. Mesurol) have become the standard for thrips control. However, in some areas, growers report that thrips pressure continues to build. Without any new product in the immediate future, growers are reminded to continue to rotate the use of pesticides to prolong the effectiveness of any one product. Continued use of one class of pesticides increases the chance that thrips and other pests will become resistant. Inspect and monitor new material before bringing it into production areas. Also, keep greenhouses free of weeds as well as the exterior perimeter of the greenhouse, especially areas near vents and doorways.
