In this issue of the Fresh Market Strawberry Bulletin:
  • Read the Fall 2018 evaluations on each strawberry variety in our four-year trial. (Go here for some background information on this project and for summaries of each variety in the trial). 
  • Mark your calendars for our first Washington-based Fresh Market Strawberry Workshop on November 29, 2018. 
  Fresh June bearer trial fall evaluations

Sangria plants had a range of 56% to 100% live plants. An average of 2.5 crowns were found per plant and a wide range (0-11) of runners were found per plant dependent on location. There was no Powdery Mildew disease presence in this variety, but one field had mottled leaves from a mite infestation that seemed to impact this variety more so than the others in this trial. Generally, the organic production of this variety saw the least number of runners and plant growth compared to the conventionally managed trial plots.

Emilia plants had an average of 88% of plants surviving since spring planting. Similar to Sangria, the organic produced plants had fewer (1.5) crowns, no runners and nutrient deficient leaf coloring (yellowing and purpling) versus the conventional managed plants which averaged 2.5 crowns and 13.5 runners per plant. Powdery Mildew was occasionally found but no other disease or insect symptoms were observed in this variety.  Generally, this variety appeared to be weaker (total canopy size and coloration) in both the organic and conventional plantings compared to the other plantings.

Ruby June plants had an average of 92% live plants and two crowns per plant. There was an average of one runner per plant in the organic production plot compared to the 11 runners per plant average in the conventional plots. Plants were without disease or insect symptoms across all plots evaluated. Generally, the runners have started growing the last week of August and have filled in the row better than other varieties at this time with at least one crown per daughter plant.

Camila plants had a large range of live plant percentages depending on plot location with 100% surviving plants found in the organic plot while between 24% and 64% surviving in the conventional plots. Plants remaining in the plots look much weaker in appearance. One plot with the lowest surviving number of plants appeared to show a possible sensitivity to Dual and Spartan herbicide application compared to other varieties under the same conditions. The organic produced plants appeared to be the most robust of all the organic trial plantings though some leaf yellowing was noticeable in this plot. There were an average of 2.5 crowns per plant and there were between 5 and 19 runners per plant depending on the plot location. Very low level of Powdery Mildew was found across all plots.
  Day neutral trial fall evaluations   
ABOVE: WSU 12.216-3
WSU 12.216-3 had an average of 3.5 crowns per plant with no runners found in either location. An average of 92% of live plants remained since the spring planting. Powdery mildew was found at very low levels at one of the two locations. Consistent fruiting occurred through the season thus far though fruit was slightly smaller in size and capped easier compared to the neighboring Albion fruit. Significantly more new fruit spurs and crowns were found on these plants versus Albion especially in the later part of the fruiting season. Organic production plots have smaller, yellowing leaves which could be related to the organic nutrition practices used. In the conventional field, a general observation shows the effect of lygus bug appears more severe on these berries than on the Albion berries in the same field. General plant growth is more robust than the Albion standard, however these are also plug plants are being compared to Albion bareroot plants.
 Processed trial fall evaluations

Marys Peak had an average of three crowns per plant with 7.5 runners per plant. Late season Powdery Mildew was found at very low levels and there was one average crown per daughter plant. 90% of plants that have survived the summer. Growers observed this variety producing runners sooner than Puget Crimson (beginning of August) though these plants are more sensitive to Stinger herbicide application than Puget Crimson plants.

Puget Crimson had an average of four crowns per plant with 10 runners per plant. Late season Powdery Mildew was found at very low levels and there were 1.5 average crowns per daughter plant. 92% of plants that have survived since planting. Grower observations include this variety producing runners later than Marys Peak (end of August) and the leaf color is generally darker color than other varieties.
  Upcoming Strawberry Events   
Join us for a Fresh Market Strawberry Workshop at the Washington Small Fruit Conference
When: Thursday November 29, 2018.

Where: Fall Creek Nursery Room at the WA Small Fruit Conference (NW Washington Fairgrounds, 1775 Front Street, Lynden, WA). This event will also be broadcast in Prosser (1228 Mead Avenue, Prosser, WA) and Vancouver (1919 NE 78th St., Vancouver, WA). 

About the Fresh Market Strawberry Workshop: This is a day-long workshop held in conjunction with the Washington Small Fruit Conference and Lynden Ag Show. The workshop will cover all aspects of fresh market strawberry production and marketing, including:
  • Introduction and Panel Discussion on Present State of the Washington Fresh Strawberry Market
  • Mid-late Season Pest Management for Day Neutral strawberries
  • Question and Answer Panels: Stories from Fresh Strawberry Growers/ Interest from Potential Buyers
  • Fresh Strawberry Research Update
  • Weed Management Update and Strawberry Herbicide Discussion
  • Fresh Market Equipment and Supplies Discussion and Audience Response Survey
About the Washington Small Fruit Conference: Washington Small Fruit Conference is a 3-day conference (Nov. 28 -30), presented Live in Lynden and broadcast to Prosser & Vancouver, with the latest relevant research information delivered by the scientists performing the research. This conference is presented in association with the Lynden Ag Show, a trade show featuring vendors serving the small fruit community.
