Spotted wing drosophila

With any fruit crop, it is important to monitor and routinely check for insects and disease.  Once such insect that can be especially devastating to a strawberry crop is the spotted wing drosophila (SWD). In 2014, we changed our trap cup design.  We used a clear plastic quart-size cup, with lid, as seen below.  We […]

Strawberry leaf spot disease

In September, we noticed strawberry leaf spot in the non-low tunnel treatment, but not in the low tunnel.  This occurred at both the St. Paul and Morris locations.  For reasons unknown to us, the leaf spot affected only the non-low tunnel but not the low tunnel treatments.    

Western flower thrips causes damage to non-low tunnel fruit

During the August 2014 harvest period, we noticed fruit damage from western flower thrips.  Western flower thrips are slender, very small insects, about 0.03 inch long when mature.  Adults have feathery wings and vary in color from yellow to dark brown; nymphs are white or yellowish with small dark eyes. Thrips feed on strawberry blossoms, […]

Twospotted spider makes an appearance in low-tunnel system

Twospotted spider mite damage was detected on the leaves of day-neutral strawberry plants under the low-tunnel system in late July.  While the damage was slight, it certainly came as a surprise since we did not experience this type of insect problem in 2013 with our low-tunnel system.  Typically, the twospotted spider mite is found in […]

Low Tunnel Tour!

The University of Minnesota (U of MN) and the West Central Research and Outreach Center (WCROC), Morris, invite you to a tour of our day-neutral low tunnel strawberry plot.  Tours will be held on Thursday, July 24, 2014 beginning at 5:15 pm and again at 7:30 pm, running one hour in length each time. The […]

Gearing up for another growing season

We are gearing up for another exciting year of day-neutral low tunnel strawberry farming.  The growing season of 2013 provided us with valuable opportunities to learn how this system can work for strawberry growers in the Upper Midwest.  Based on what we learned, we are heading into our second year with a few tweaks and […]

What we learned

With one growing season under our belt, we now have a better idea of where we need to focus our research efforts in year two in order to improve the low tunnel system.  Watch as Steve Poppe shares his thoughts and ideas for improvements for the 2014 growing season.        

End of season day-neutral strawberry yields

One of the objectives of our project was to determine if the use of a low tunnel system with day-neutral strawberries could provide adequate yields.  Traditional June-bearing strawberry varieties in Minnesota have a baseline yield of 5,500 pounds per acre (lb/A).  As shown below, lb/A of each of the six cultivars in the low tunnel and non-low […]
