It grows naturally in various half shaded and sunny habitats such as open forests and edges of farmland47,48. Across our study area (central Sweden) flowers are produced throughout the entire growing season from May until September, with a clear peak in early June48. In addition to sexual reproduction, woodland strawberry is also capable of clonal reproduction and forms a high number of runners that grow quickly into self-sustaining plants47. The 16 plant genotypes used in this study were derived from distinct wild populations in Uppsala County, Sweden, during spring 201224,25,49 (Supplementary Material Table 1). Following the clonal propagation for several generations, forty runners per plant genotype were transplanted into a common garden close to Uppsala (N59.741°, E17.684°) in autumn 2013.

FRESH FRUIT PORTAL 13/03/19 The Biocontrol Brief: How to control two-spotted spider mites in strawberry production

With an annual value of about $2.6 billion, California represents close to 90% of the United State’s strawberry production, followed by Florida, which is by far the largest domestic producer of winter strawberries. Despite their large sizes, these crops are being put in significant danger by some tiny threats. “Arthropods” more commonly known as spider mites are threatening our ability to enjoy these sweet red delicacies year-round. This very small (1/100 – 1/50 inches / 0.3 – 0.5mm) yellow/green pest with large dark spots on each side of their body can cause significant yield loss.

Growers should pay special attention when the weather is dry and hot, as these conditions promote the emergence of pest populations.

In turn, California is the leading producer in the U.S., accounting for 87% of the nation's strawberry production (29). The Watsonville area annually grows strawberries on about 5,000 hectares, accounting for about 40% of the strawberry acreage in the state (29). The selection of 13 field pairs (5 in 2004 and 8 in 2005) from commercial strawberry farms was made on the basis of grower interviews and on-farm field examinations to ensure that all soil-forming factors, except management, were the same for each field pair [21].

For tuning up sustainable organic strawberry production new measures in pest management needs to be developed. Both pest insects and pathogenic fungi reduces yields and fruit quality. Present study shows that mass trapping of strawberry blossom weevils by using volatile baited traps is not an efficient measure in an established field. Repository Staff Only: item control page.

By increasing the plant resistance, the dependence on those resources may decrease. "The supermarket chains are increasingly demanding higher standards regarding the number of used active ingredients and the residue. The consumer is entitled to a completely reliable and safe product. That is what we have to work on. The possibilities and opportunities are there," according to Dutch strawberry grower Michiel Penninx. Together with his colleague Rob van Enckevort, he took the initiative to see if strawberry cultivation could become more sustainable. A necessity, because sustainability is not yet a priority among the growers, Penninx explains. Michiel Penninx: "The products are available.

The way of conventional means is ending The problem is complex, according to Penninx. UNIVERSITE LAVAL (QC) 06/12/17 Présentation : La fraise bio : où et comment?

Ce cocktail développé par la firme belge Viridaxis est commercialisé sous le nom de FresaProtect. En Suisse, la première année, avec des conditions météorologiques très fraîches en avril, les parasitoïdes ont eu de la peine à s’installer et la population de pucerons n’a pas pu être maîtrisée. L’année suivante, elle a pu être contrôlée avec succès en commençant les lâchers de parasitoïdes plus tôt dans la saison dans un tunnel fermé. Dans le tunnel témoin conduit en production conventionnelle, quatre traitements chimiques ont dû être appliqués, contre aucun dans le tunnel en test.
