Potatoes (Solanum tuberosum L.) are produced in all Canadian provinces, and interest has increased in the use of non-synthetic chemicals and organic techniques to provide weed control. Acetic acid has been suggested as a chemical that could potentially provide weed control in potato production. We examined glacial acetic acid and Ecoclear (30% acetic acid, 1.0% naptha solvent and 1.0% trimethyl benzene) for effectiveness in controlling weeds in potatoes when applied in a 30-cm-wide band over the potato row as well as their effect on potato yield components in three experiments repeated over 2 yr. The effects of time of application and volume of application were also examined. Glacial acetic acid at 10% concentration did not injure potato foliage, but at 20 and 30% concentration it injured emerged potato foliage. A concentration of 20% acetic acid was needed to provide acceptable weed control levels of lambs-quarters, corn spurry and wild buckwheat. Marketable yield was reduced by 20 and 30% acetic acid to below the standard herbicide treatment. Sequential applications of acetic acid at concentrations of 10, 20 or 30%, applied 7-10 d apart, caused slightly greater injury and yield was 10 to 15% less than in the single application. Ecoclear applied to emerged weeds and before potato emergence did not injure potato foliage, but when applied post-emergence it caused severe, but short lived, potato injury. Ecoclear gave greater than 80% control of lambs-quarters, corn spurry and wild radish. Potato marketable yield was comparable with that achieved with a herbicide and was reduced only in one year by Ecoclear applied post-emergence. Weed control was 18% or less when Ecoclear was applied at 200 L ha-1, 54 to 74% when applied at 400 L ha-1 and 91 to 95% when applied at 800 L ha-1 volume of application.

Weeds Control

Increasing costs of production have resulted in intensified efforts to reduce the amount of herbicides applied in potato production. This research evaluated the potential of applying herbicides in 30-cm-wide bands over the potato row in combination with cultivation between the potato rows to achieve weed control. At a moderate to high infestation of quackgrass and annual broadleaf weeds, control of quackgrass, corn spurry and wild radish was as effective with the banded herbicide + cultivation treatments as with the broadcast herbicide treatment. Potato marketable yields from the banded herbicide + cultivation treatments were comparable to the broadcast herbicide application treatment. A single cultivation at 21 d after planting (DAP) (at ground crack), 28 DAP (potatoes 5 to 10 cm tall) or 35 DAP (potatoes 10 to 15 cm tall) did not give adequate weed control, and potato yields were reduced by 30% or more at all times of cultivation compared to herbicide treatments. This study shows that acceptable weed control without effects on marketable yield is possible by using a 30-cm-wide herbicide band over the row followed by cultivation to remove weeds between the row. The amount of herbicide used per hectare with this technique is reduced by 66% compared to a broadcast herbicide application. Key words: Herbicide, potato, quackgrass, Elytrigia repens L.

Water Tables

To study potato (Solanum tuberosum) response to drainage in a poorly drained high-S de l’Anse clay loam (sulfaquept), five or six cultivars were grown for 3 consecutive years on separate plots where the water table fluctuated naturally or was maintained at 0.46-, 0.76-, or 1.22-m depth during the growing season. As the fixed water table was maintained at progressively lower levels, marketable tuber (> 45 mm) yields declined linearly from 0.46 to 1.22 m in a year with normal July rainfall. Marketable yield plateaued at 0.76 m then decreased in years with wet or dry July periods. Specific gravity of the potatoes declined each year. The reduction was greater from 0.46 to 0.76 than from 0.76 to 1.22 m in the dry and wet years. In the wet year, there was a slight increase in specific gravity from 0.76 to 1.22 m. Soil temperature and soil pH showed no effect of water table reduction. Generally, the values for variables measured on the controls where the water table fluctuated naturally occurred somewhere between the two extremes of those measured between 0.46 and 1.22 m. Therefore, there was no advantage in lowering the water table for crop growth on a high-water-table soil and doing so resulted in negative effects due to less water being available. These negative effects were not due to increased acidity on this cat clay. Since water table had no effect on soil pH, it may be that the sulfur compounds in this soil were not significantly labile.Key words: Solanum tuberosum L., cat clay, water table

Linuron, metribuzin, oryzalin, and metolachlor were applied at recommended (1X) and two-thirds (0.67X) rates to evaluate control of redroot pigweed and common lambsquarters in conventional and rye-stubble reduced-tillage potato production systems. Regardless of tillage, common lambsquarters control was satisfactory during both seasons at both rates of linuron, metribuzin, and oryzalin. Redroot pigweed control by these three herbicides, although excellent in 1988, was poor in RT plots during 1987. Yields did not differ between tillage systems. Reduced weed control with metolachlor during both seasons, and possible crop injury with linuron in 1987 resulted in significant yield reductions.

Background: In a Mediterranean agrosystem of low productivity, a study was carried out on the effects of municipal solid waste compost (MSWC) compared to other organic and inorganic amendments on the production, quality and yield of three potato varieties (Solanum tuberosum L.) and an advanced clone. Method: Simultaneously, the agronomic and nutritional parameters of the potato crop, the degree of bioavailability and the possible risks of heavy metal contamination were studied. Results: Two stages are observed in the yield and content of macro, micronutrients and heavy metals. The addition of all amendments and especially that of urban waste compost increased potato production and the content of macronutrients, micronutrients and heavy metals in the soils of all varieties, showing a progressive accumulation in tubers. Nevertheless, the performance is not maintained over time with a notable decrease during the second stage of its application. Conclusion: Highlighting the potato clone A7677 not only in its performance but also in the concentration of iron, zinc, copper, essential micronutrients for human consumption and especially for populations deficient in these trace elements.

Bacterial Wilt Disease

Bacterial wilt caused by Ralstonia solanacearum is one of the most important bacterial diseases in potato production. This study aimed to obtain the transgenic potato (Solanum tuberosum L.) cultivar IPB CP3, containing LYZ‐C gene encoding for lysozyme type C, resistant to bacterial disease caused by R. solanacearum. Genetic transformation using Agrobacterium tumefaciens LBA4404 to 124 internode explants resulted in the transformation efficiency of about 47.58% with a regeneration efficiency of approximately 30.51%. Gene integration analysis showed that 16 clones were confirmed as transgenic clones containing the LYZ‐C gene. Analysis of resistance to R. solanacearum of three transgenic clones showed that all three transgenic clones were more resistant than a non‐transgenic one. This result showed that the LYZ‐C gene integrated in the genome of transgenic potato increased the resistance of potato plants to R. solanacearum. We obtained two transgenic clones considered resistant to bacterial wilt disease.

Plant Sci. 92: 783–794. Potassium is frequently applied to irrigated potato in Manitoba. Field experiments were conducted at two sites in each of 2006, 2007 and 2008 to assess effects of rate and timing of potassium chloride (KCl) application on the yield, quality, and nutrient status of irrigated potato (Solanum tuberosum ‘Russet Burbank’) in southern Manitoba. Preplant application of KCl increased total and marketable yield at one site, and tended (0.05<P ≤ 0.10) to increase total and marketable yield at three additional sites. At three of the four K-responsive sites, soil test K levels were <200 mg NH4OAc-extractable K kg−1, the level below which K fertilizer is recommended based on existing guidelines. Effects of timing of KCl application on total and marketable yield were limited although, averaged across sites, KCl applied at hilling reduced the yield of small tubers (<85 g) and increased the proportion of larger tubers (170 to 340 g) compared with preplant application. Averaged across sites, KCl applied preplant or at hilling reduced specific gravity compared with the 0 KCl treatments. Improvements in fry colour with KCl application were evident at only one site. Petiole and tuber K and Cl− concentration, K and Cl− removal in harvested tubers, and post-harvest soil test K concentration increased with KCl application. However, petiole K concentration measured 82 to 85 d after planting predicted only 24% of the variability in relative marketable yield for sites containing between 164 and 632 mg NH4OAc-extractable K kg−1 to 15 cm. Results demonstrate the potential for yield increases and specific gravity declines with KCl application under Manitoba conditions, but suggest that further research will be required to better predict the potential for yield responses using soil and petiole testing.

Irrigation is required for profitable commercial potato (Solanum tuberosum L.) production. Excessive or deficit soil water availability during the growing season can have adverse effects on tuber yield, quality, and storability. A field study was conducted during the 2018 and 2019 field and storage seasons in Central Wisconsin, a region in the U.S. with a high volume of potato production, to evaluate the impacts of different irrigation rates on three chipping potato varieties, Hodag, Lamoka, and Snowden. The treatments were implemented during the late-tuber bulking and tuber maturation growth stages, and consisted of irrigation at 125%, 100%, 75%, and 50% of crop evapotranspiration (ET). Irrigation before the treatment period was at 100%ET for all plots. With the industry standard irrigation practice being at 100%ET, other treatments were designated as over-irrigation or deficit irrigation. The impact of these watering rates on tuber yield and quality was evaluated at harvest, and tuber storage quality was assessed by measuring chip fry color and sugar concentrations at 0, 4, and 8 months of storage. It was found that compared to the standard practice, the over-irrigation treatment at 125%ET when tubers reached late bulking resulted in no significant increase in total yield, marketable yield, tuber quality at harvest and during storage, as well as reduced irrigation efficiency (IE) and water-use efficiency (WUE). This treatment also increased nitrate leaching potential in both years. In comparison, deficit irrigation at 75%ET or even 50%ET during the late season had no impact on tuber growth, could increase IE and WUE in one of the two years, and showed reduced drainage. In both years, irrigation rate had no significant effects on hollow heart incidence, tuber specific gravity at harvest, and fry quality during the 8-month storage period. This study suggested that over-irrigation was not beneficial for potato production in Central Wisconsin of the U.S., and deficit irrigation during late tuber bulking and tuber maturation stages could potentially result in more sustainable water use while not penalizing tuber yield, quality and storability of chipping potatoes.
