“…Similarly, Hatterman-Valenti (2014) reported delayed emergence, distorted leaflets with random puckers on the leaf surface, and leaf strapping when potato seed tubers derived from mother plants treated with glyphosate were grown. These symptoms are also similar to what would be expected from synthetic auxin herbicide activity on potato (Thornton et al 2013). Symptom severity varied widely and, as reported by Hatterman-Valenti (2014), did not appear to be associated with a specific glyphosate and/or dicamba rate applied to the mother plants.…”

Increased use of dicamba and/or glyphosate in dicamba/glyphosate-tolerant soybean might affect many sensitive crops, including potato. The objective of this study was to determine the growth and yield of ‘Russet Burbank’ potato grown from seed tubers (generation 2) from mother plants (generation 1) treated with dicamba (4, 20, and 99 g ae ha−1), glyphosate (8, 40, and 197 g ae ha−1), or a combination of dicamba and glyphosate during tuber initiation. Generation 2 tubers were planted near Oakes and Inkster, ND, in 2016 and 2017, at the same research farm where the generation 1 tubers were grown the previous year. Treatment with 99 g ha−1dicamba, 197 g ha−1glyphosate, or 99 g ha−1dicamba + 197 g ha−1glyphosate caused emergence of generation 2 plants to be reduced by up to 84%, 86%, and 87%, respectively, at 5 wk after planting. Total tuber yield of generation 2 was reduced up to 67%, 55%, and 68% when 99 g ha−1dicamba, 197 g ha−1glyphosate, or 99 g ha−1dicamba + 197 g ha−1glyphosate was applied to generation 1 plants, respectively. At each site year, 197 g ha−1glyphosate reduced total yield and marketable yield, while 99 g ha−1dicamba reduced total yield and marketable yield in some site-years. This study confirms that exposure to glyphosate and dicamba of potato grown for potato seed tubers can negatively affect the growth and yield potential of the subsequently grown daughter generation.

“…Occasionally, one or two small daughter tubers formed from the seed piece sprout masses, even though no aboveground plant was ever produced. A few plants with delayed emergence had distorted leaflets with random puckers on the leaf surface and leaf strapping; similar to what would be expected from a synthetic auxin herbicide (Thornton et al 2013). These symptoms varied widely, and plants with these symptoms were sporadic and did not appear to be associated with a specific glyphosate rate applied to the mother plants.…”

Field trials were conducted to evaluate the effect of simulated glyphosate drift rates applied to two non-irrigated potato cultivars in the late tuber bulking stage grown for potato seed production. Mother plants receiving a sublethal glyphosate application had similar yields regardless of the year or cultivar. ‘Red LaSoda' seed pieces visually evaluated the following spring had more sprout inhibition from glyphosate-treated plots. With ‘Russet Burbank', only seed pieces from mother plants that received more than 18 g ha−1 glyphosate showed sprout inhibition. Total yield reductions the year following glyphosate treatments were attributed to fewer and smaller tubers from plants that did not emerge or were delayed in emergence. Red LaSoda seed pieces from mother plants receiving ≥ 71 g ha−1 glyphosate yielded less than the nontreated. In 2005, Russet Burbank seed pieces from mother plants receiving ≥35 g ha−1 glyphosate had reduced yields, whereas in 2006, all glyphosate treatments reduced total yield compared with the nontreated.

“…According to Sawicka (1999), growth regulators (Mival, Potejtin, Moddus 250 ME) intensified the severity of Streptomyces scabies infections, in particular in dry years. 2,4-dichlorophenoxyacetic acid (2,4-D) reduced the symptoms of the disease caused by S. scabies (Waterer 2010) and influenced the growth of potato plants, potato yields and the color of red-skinned cultivars (Red LaSoda and TerraRosa) (Thornton et al 2013). In a previous study by Cwalina-Ambroziak et al 2015, Bio-Algeen S-90 and Kelpak SL growth regulators and the Asahi SL biostimulant did not affect the severity of common scab, soft rot and black scurf on stored potato tubers.…”

The Effect of Biostimulants on the Health Status and Content of Chlorogenic Acids in Potato Tubers (Solanum Tuberosum L.) with Colored Flesh

The aim of this study was to evaluate the influence of cultivar and biostimulants on the health status of potato tubers after harvest and after 5 months of storage. The fungal pathogens isolated from potato tuber were cultured on PDA. The biostimulants limited the symptoms of dry rot in cv. Satina after harvest, in stored cv. Irga (Bio-Algeen S-90) and cv. Blaue St. Galler (Kelpak SL). The symptoms of common scab were reduced in stored potatoes cv. Satina in the Asahi SL treatment and the symptoms of late blight in stored potatoes cv. Satina in the Kelpak SL and Trifender WP treatment and in cv. Valfi in the Bio-Algeen S-90 and Kelpak SL treatment. Asahi SL and Kelpak SL decreased the severity of black scurf in stored potatoes cv. Irga. Biostimulants decreased the occurrence frequency of the causative agents of dry rot and black scurf after harvest. Total chlorogenic acid, which is predominant in potato tubers, was present in higher concentrations in the skin than in the flesh. Potato tubers had the highest content of 5-caffeoylquinic acid, followed by neochlorogenic acid (3-caffeoylquinic acid) and cryptochlorogenic acid (4-caffeoylquinic acid). Higher concentrations of chlorogenic acid were found in potato cultivars with blue-purple-and red-colored flesh than in those with yellow-and cream-colored flesh, and in response to the application of the Asahi SL biostimulant and Trifender WP.
