On-Farm Integrated Pest Management Trials for 1995
This article was published originally on 5/5/1995For the third consecutive year, ISU specialists Mark Gleason and Donald Lewis will coordinate on-farm trials of Integrated Pest Management (IPM) methods for control of diseases and insect pests. The crops involved this year, and the disease/insect problems targeted, are as follows:
The IPM methods in these cooperative trials are well tested through years of grower use in Iowa and many other locations. Cooperators find that the methods involve very little additional work for them. The biggest incentive is that the IPM methods can save pesticide sprays. An average reduction of 30% in sprays - with no increase in insect or disease damage to the crop - is common, but spray savings can be higher or lower depending on weather and pest populations and past spray practices. Fewer sprays translates to greater profitability.
Over 30 growers are involved in the 1995 on-farm IPM trials. These include:
Harold and Jo Dilts, Ames (tomatoes)
In addition, several melon growers in the Muscatine area will be involved in cooperative trials for disease control on watermelon and muskmelon.
Grower survey. A written survey will be mailed to all Iowa Fruit and Vegetable Growers Association (IFVGA) members in late summer, in order to help us measure the impact of our IPM on-farm trials and education efforts. They are an essential part of our project, and will help us to secure grant funds to support future IPM efforts in Iowa.
Videos. With help from ISU Extension Communications, we plan to develop two videotapes on IPM themes this summer. One will focus on the on-farm IPM trials for four crops, while the other will focus exclusively on strawberry IPM. Both videos will incorporate extensive footage from the on-farm trial sites at various stages in the crop cycle from bloom through harvest.
County and field staff involvement. We hope that Extension staff in county and field specialist positions will take an interest in these cooperative trials. We, or your local cooperating grower, can provide additional information about the trials. We'd welcome any media interest in these efforts to minimize pesticide use while maintaining or enhancing profitability. Please let us know if we can help in any way.
