Encouraging Adoption of IPM in Muck Onion Production Through the Use of Demonstrations 1997

Project Leader: Lee Stivers

Objective:

Compare the effectiveness of the IPM program to the conventional management program of weekly sprays.

Results:

Disease pressure and thrips population were both relatively low in 1997. The conventional field received 2 insecticide sprays for thrips, and the IPM field received one. The IPM field required four applications of fungicide, and the conventional field required five. Yields were virtually identical in the IPM and the conventional fields. Spray costs were lower in the IPM field. The grower whose farm was used for the demonstration has converted his entire operation to IPM methods.
