“…However, the resilience of miscanthus with regard to insect, disease, and cold in North America remains an open question. Evaluating North American miscanthus, Bradshaw et al (2010) reported infestations of yellow sugarcane aphid (Sipha flava) and corn leaf aphid (Rhopalosiphum maidis), both of which are known vectors of potyviruses. Similarly, Falter and Voigt (2014) screened 13 fungal species on detached miscanthus leaves and identified four that were infectious.…”

Biomass Production a Stronger Driver of Cellulosic Ethanol Yield than Biomass Quality

Core Ideas Fermentable sugars were greatest in corn stover > perennial grasses > polycultures. Corn stover had the highest ethanol content. Miscanthus had the highest ethanol yield potential on a per hectare basis. Ethanol yield potential per hectare of switchgrass ≥ corn stover. Biomass yield was the strongest driver of per hectare ethanol yield. Many crops have been proposed as feedstocks for the emerging cellulosic ethanol industry, but information is lacking about the relative importance of feedstock production and quality. We compared yield and sugar content for seven bioenergy cropping systems in south‐central Wisconsin (ARL) and southwestern Michigan (KBS) during three growing seasons (2012 through 2014). The cropping systems were (i) continuous corn stover (Zea mays L.), (ii) switchgrass (Panicum virgatum L.), (iii) giant miscanthus (Miscanthus × giganteus Greef & Deuter ex Hodkinson & Renvoize), (iv) hybrid poplar (Populus nigra × P. maximowiczii A. Henry ‘NM6’), (v) native grass mix, (vi) early successional community, and (vii) restored prairie. A high‐throughput pretreatment and fermentation assay showed corn stover with the highest sugar content (213 g glucose kg−1 [Glc] and 115 g xylose kg−1 [Xyl]) followed by the two monoculture perennial grass treatments (154 [Glc] and 88 [Xyl]) and then the herbaceous polycultures (135 [Glc] and 77 [Xyl]). Biomass production and sugar content were combined to calculate ethanol yields. Miscanthus had the highest per hectare ethanol yields (1957 l ha−1 yr−1 ARL, 2485 l ha−1 yr−1 KBS) followed by switchgrass (1091 l ha−1 yr−1 ARL, 1017 l ha−1 yr−1 KBS) and corn stover (1121 l ha−1 yr−1 ARL, 878 l ha−1 yr−1 KBS). Perennial grass cropping systems (i.e., switchgrass and miscanthus) had higher per hectare ethanol yields at both sites relative to diverse systems that included dicots. Despite feedstock differences in fermentable sugars, biomass production was the strongest driver of per hectare ethanol yield.

“…There have been no reports of pests in commercial plantings in Europe. In the United States, however, several aphids (Bradshaw et al, 2010) have been reported recently and Mxg may be a site of oviposition and emergence for the western corn rootworm, a major pest of corn in the Midwest (Spencer and Raghu, 2009). Also, a leaf spot disease (Ahonsi et al, 2010) has been reported on Mxg plantings in Kentucky.…”

“…Many of the plant species suggested for possible widespread planting as biofuel crops have a history of being invasive weeds (Raghu et al 2006;Meyer et al 2010;WSSA 2012c), and their use must be considered extremely carefully to avoid disastrous "escapes" and invasions. The insects that will inevitably become the key pests in biofuel monocultures are not yet known (Landis and Werling 2010;Bradshaw et al 2010;Prasifka et al 2011). Finally, cooperation between publicsector scientists and industry is critical to dealing with these issues in an optimal way.…”
