Researchers dispatched to the fields, collected samples and documented what they found. Most importantly, researchers were able to pinpoint when certain pests would emerge and become active. They discovered, for example, that a destructive caterpillar emerged in April, and that a certain beetle arrived in June.
With this knowledge, they could anticipate threats and take preventive action. They were able to change their approach to spray for a target pest during the precise time when it would be vulnerable. They also began to rotate materials and use a different chemistry to keep pests from developing resistance.
