ABSTRACT:
Implements for the removal of insects or the like are provided which dedicate an individual centrifugal fan unit to each plant row. The fan unit includes exhaust means which are constructed to traverse the top of the plant row in order to direct the exhaust airflow to the side of the plant opposite the fan intake. The exhaust airflow contacts and passes through the plant in order to facilitate insect removal. A portion of the exhaust airflow reenters the intake airflow thereby forming a closed circuit airflow. This closed-circuit airflow also permits the introduction of fluids such as pesticides or herbicides into the airflow while minimizing both fluid usage and fluid introduction into the general surrounding environment.
