Leaf spot disease

We have noticed slight leaf spot disease on the Albion day-neutral strawberry leaves within the last two months.  However, the disease pressure has increased in the last two weeks in the non-low tunnel plot.  As you can see below, the leaf spot is much more prevalent on the non low-tunnel plant leaves than in the […]

Day-neutral flower and runner removal

For our day-neutral strawberry project, we chose to remove flowers and runners early in the growing season, thus putting all of the plants growing energy into producing fruit.  We first removed flowers and cut runners in late May, again in early June and, finally in early July.  Timing of early July flower removal should provide […]

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 30, 2015 beginning at 5:15 pm and again at 7:15 pm, running one hour in length each time. Low […]

Gearing up for the 2015 growing season

The winter months are the perfect time to make plans and preparations for our day-neutral low tunnel strawberry growing season.  We learned about a retractable tunnel system from Dubois Agrinovation out of Quebec, Canada.  After doing some further investigation of the system, we decided it give it a try for this year. In the past, […]

Frost damage in day-neutral strawberries

The official air temperature at the West Central Research and Outreach Center on October 4, 2014 was 32 degrees.  Even with the air temperature at 32, the temperature recorded in the low tunnel system was 34 degrees, which prevented the day neutral strawberry flowers and fruit from frost damage.  By comparison, the non low tunnel […]

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.    

Mid-September Harvest

Even though cooler night temperatures in mid-September caused a decrease in fruit yield, the quality, appearance, size and flavor of these day-neutral strawberries remains excellent, as documented in our September 18 harvest:   Harvest began in early August for day-neutral varieties in both the low-tunnel and non-low tunnel systems, with two pickings per week.  The […]

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 […]
