Interpretive Summary: Methyl jasmonate (MeJA) and salicylic acid (SA) have been reported to enhance yield and protect crop plants and products against environmental stresses and diseases. The effect of these compounds on sugarbeets, however, is unknown. Research was conducted in 2015 and 2016 to investigate the effects of an early season MeJA treatment, a late season MeJA treatment, or an early season SA treatment on sugarbeet root yield, sucrose content, and storage properties. All treatments were applied singly or in combination with a late season treatment of Headline, a commonly used fungicide. Postharvest Stadium™ treatments, with or without Headline treatment, were also applied and evaluated for their effect on storage properties. In 2015, roots from plants that received an early season MeJA treatment + a late season Headline treatment had improved storage properties, including reduced storage respiration rate at 30 days after harvest (DAH), reduced sucrose loss to molasses at 30 and 90 DAH, and increased quantities of recoverable sugar at 30 DAH. Beneficial effects from a Stadium + Headline treatment were also observed. Roots receiving this treatment had reduced respiration rate and reduced sucrose loss to molasses at 90 DAH. In 2016, no treatment significantly affected root yield or sucrose content at harvest. Evaluation of storage properties for the 2016 field study is ongoing.

Technical Abstract: Methyl jasmonate (MeJA) and salicylic acid (SA) have been reported to enhance yield and protect crop plants and products against abiotic stresses and diseases. The effect of these compounds on sugarbeets, however, is unknown. Research was conducted in 2015 and 2016 to investigate the effects of an early season MeJA treatment, a late season MeJA treatment, or an early season SA treatment on sugarbeet root yield, sucrose content, and storage properties including root respiration rate, sucrose loss, invert sugar accumulation, and root firmness. All treatments were applied singly or in combination with a late season treatment of pyraclostrobin (Headline), a commonly used fungicide with purported hormone-like attributes. Postharvest Stadium™ treatments, with or without Headline treatment, were also applied and evaluated for their effect on storage properties. In 2015, roots from plants that received an early season MeJA treatment + a late season Headline treatment had improved storage properties, including reduced storage respiration rate at 30 days after harvest (DAH), reduced sucrose loss to molasses at 30 and 90 DAH, and increased quantities of recoverable sugar at 30 DAH. Beneficial effects from a Stadium + Headline treatment were also observed. Roots receiving this treatment had reduced respiration rate and reduced sucrose loss to molasses at 90 DAH. In 2016, no treatment significantly affected root yield or sucrose content at harvest. Evaluation of storage properties for the 2016 field study is ongoing.
