Benzoxazinoids in Rye Allelopathy - From Discovery to Application in Sustainable Weed Control and Organic Farming

Abstract: The allelopathic potency of rye (Secale cereale L.) is due mainly to the presence of phytotoxic benzoxazinones-compounds whose biosynthesis is developmentally regulated, with the highest accumulation in young tissue and a dependency on cultivar and environmental influences. Benzoxazinones can be released from residues of greenhouse-grown rye at levels between 12 and 20 kg/ha, with lower amounts exuded by living plants. In soil, benzoxazinones are subject to a cascade of transformation reactions, and levels in … Show more

“…The phytotoxic allelopathic effects produced by rye residues are thought to be primarily due to benzoxazizone compounds. The biosynthesis of these compounds is greater in younger tissues and varies with rye cultivars and environmental factors [88]. In roller-crimper systems, where rye is terminated at a late stage and residues are not incorporated into the soil, allelopathy may have a limited role in weed suppression compared with the physical suppression provided by the vegetative mulch.…”

“…This shows potential for fall rye or winter wheat to be used as a cover crop incorporated at early growth stages for utilization of allelopathy for weed suppression. We did not evaluate known allelochemicals in fall rye or winter wheat because these putative benzoxazinoid allelochemicals and their derivatives are relatively unstable and not readily available aside from chemical synthesis [9] [12] [37]. Interestingly, reproductive stage fall rye had the greatest stimulatory effect on radicle elongation of response species; likely due to hormesis caused by the decrease of hydroxamic acids in fall rye tissue throughout its development [4] [9] [36].…”

“…The concentration of HBOA was found to increase as DIBOA and BOA degraded, reaching its maximum concentration (~100 ng·g −1 DW soil) in soil four days after the incorporation of rye [12]. Lamb's quarters seedlings have been noted to have a strong detoxification mechanism against benzoxazinoid allelochemicals [9]. In a greenhouse tray experiment, leachate from hairy vetch mulch had a stimulatory effect on the emergence of lamb's quarters seedlings [16].…”

“…Similarly, plants from the Poaceae family, such as oats (Avena strigosa Schreb. and Avena sativa L.) and rye (Secale cereale L.), are useful cover crops in the NT system because they can reduce the weed population (Tabaglio, Gavazzi, Schulz et al 2008;Gavazzi et al 2010;Bittencourt et al 2013;Schulz et al 2013). However, the straw of ryegrass (Lolium multiflorum Lam.)…”
