Intercropping at the NIARC

Posted by Russel Higgins -

Visitors to the NIARC are surprised to see pumpkins growing in and between the rows of one our cornfields. An experiment in intercropping? In a sense, the pumpkin seed is mixed with our late planted seed corn for this particular plot. The resulting "mixed" crop serves as a trap crop for adult corn rootworm beetles. They are attracted to the late silking corn and the cucurbit flowers and we expect substantial egg laying to take place.This field will be used for rootworm management trials in 2013 in the enhanced rootworm pressure site.
