The Bollworm complex is becoming more present throughout the state. The general scenario is to find live worms but no damage squares OR find damage squares and no live worms. This indicates that the technology is working where there are live worms, and damaged squares means the technology is overwhelmed. The economic threshold is 6% damaged squares with live worms present in Bt cotton. The crop stage is critical to warrant a control spray. Cotton that is at cutout or past cutout means the likelihood of economic loss is very low. Please call this office if in doubt if a control spray is needed.
