“…Together with fruit size and firmness, a dark blue/violet peel color for blueberry fruit is a key parameter that makes the fruit intriguing to the consumer [44]. The key regulating factor of blueberry peel color is the amount of light [2], whereby a higher light quantity leads to a more intense peel color [19]. Although significant differences in the fruit color parameters were seen for the individual cultivars here, these differences were minor and were not possible to detect with the naked eye.…”

“…The modified light spectrum alters plant physiological processes, while scattered light penetrates deeper into the blueberry plant between leaves compared to direct light. The introduction of hail nets has already been established for the production of many fruit species, such as apple [15][16][17], pear [18], persimmon [19], kiwifruit [20], peach [21], and others, and demand among growers for hail net installation for blueberry orchards has started to appear in recent years [22].…”

Due to the increasing interest in highbush blueberry (Vaccinium corymbosum L.) among consumers, together with the problems of climate change and specific substrate requirements, a novel approach to intensive blueberry production is required. Here, ‘Duke’, ‘Aurora’, and ‘Brigitta’ blueberry cultivars were planted under the protective environments of a high tunnel and black hail net, each using ridge and pot planting systems. The high tunnel increased the maximal air temperature on average by 7.2 °C compared to the hail net. For all three cultivars, harvest began 6 to 18 days earlier under the high tunnel than under the hail net; however, lower yields and individual phenolics contents were obtained for the fruit. In ‘Aurora’ and ‘Brigitta’, environmental conditions under the high tunnel also reduced plant volume and fruit sugar/organic acid ratio. Growing blueberry plants in 60 L pots had no negative effects on plant volume and fruit ripening time, yield, firmness, color, and chemical composition. This study represents the first to compare highbush blueberry grown under the high tunnel and hail net protective environments using ridge and pot planting systems across three different cultivars. Here, we can conclude that optimal highbush blueberry production of ‘Duke’, ‘Aurora’, and ‘Brigitta’ under the climate conditions of the study provides earlier ripening times under the high tunnel. However, according to fruit yield and quality, all three cultivars benefit from the hail net over the high tunnel, while ‘Duke’ and ‘Brigitta’ also benefit in particular from the hail net combined with growth in pots.

“…Plastic mulches have been used in fruit and vegetable agroecosystems since the 1950s due to their ability to modify the microclimate, improve weed control, induce earlier ripening, improve fruit quality, and increase yield (Tarara 2000;Lamont 2005;Kasirajan and Ngouajio 2012). White and metallic plastic mulches reflect solar radiation and can increase canopy light intensity (Decoteau et al 1989;Jakopic et al 2007;Andreotti et al 2010;Nottingham and Kuhar 2016;Smrke et al 2019;Nottingham and Beers 2020) and canopy temperatures (Gordon et al 2008;Andreotti et al 2010) in fruit and vegetable crops. Despite the plastic mulches' ability to modify the canopy microclimate, their efficacy as a cultural control for insect pests has been inconsistent by crop and insect species.…”

Plastic mulches reduce adult and larval populations of Drosophila suzukii in fall-bearing raspberry

The invasive spotted-wing drosophila, Drosophila suzukii, is a major pest of fruit crops worldwide. Management of D. suzukii relies heavily on chemical control in both organic and conventional systems, and there is a need to develop more sustainable management practices. We evaluated the efficacy of three colors of plastic mulches at reducing populations of D. suzukii in fall-bearing raspberry and assessed the mulches’ impacts on canopy microclimate factors relevant to D. suzukii. Black, white, and metallic plastic mulches reduced adult D. suzukii populations by 42–51% and larval populations by 52–72% compared to the grower standard. The mulches did not change canopy temperature or relative humidity, but metallic mulches increased canopy light intensity compared to the black mulch. Radiance in the visible spectrum (401–680 nm) was higher for the white and metallic mulch plots, but the black mulch plots did not differ from the control. In the UV spectrum (380–400 nm), all three plastic mulches had higher radiance than the control plots. Future studies will determine whether changes in radiance are associated with the observed reduction in D. suzukii populations. Plastic mulches are a promising cultural practice for managing D. suzukii since they can reduce adult and larval populations and could be incorporated into an integrated pest management program in both organic and conventional systems.
