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 initiated in 2014 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 Headline, a commonly used fungicide with purported hormone-like attributes. In 2015, postharvest Stadium™ treatments, with or without Headline treatment, were added to the study. In 2014, plants receiving an early season MeJA treatment + a late season Headline treatment yielded 3.5 tons/acre more than untreated controls. This yield gain was not repeated in 2015, although this replication of the experiment was compromised by development of a late season Cercospora infection. No detrimental effects on storage properties were observed for any MeJA-containing treatments. Storage properties, however, were negatively impacted by the early season SA + late season Headline treatment in 2014.

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 initiated in 2014 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. In 2015, postharvest Stadium™ treatments, with or without Headline treatment, were added to the study. In 2014, plants receiving an early season MeJA treatment + a late season Headline treatment yielded 7.8 Mg ha-1 more than controls. This yield gain was not repeated in 2015, although this replication of the experiment was compromised by development of a late season Cercospora beticola infection. No detrimental effects on storage properties were observed for any MeJA-containing treatments. Storage properties, however, were negatively impacted by the early season SA + late season Headline treatment in 2014.
