HOW DO YOU ESTIMATE CORN ROOTWORM PRESSURE USING YELLOW STICKY TRAPS?


Assessing adult corn rootworm activity with yellow sticky traps is an important scouting tactic and is key to staying ahead of the threat. If you haven’t set traps before, you can learn more here. Reading the results of those yellow sticky traps does require some math. While crunching numbers isn’t everyone’s favorite part of farming, calculating the average number of beetles in your fields is easy with this equation.
