Response of Seed Potato (Solanum tuberosum) Cultivars to Glyphosate

Field trials were initiated during 2004 at a dryland site near Prosper, N.D., to evaluate the effects of simulated drift from glyphosate to `Russet Burbank' and `Red Lasoda' seed potato during the early senescence stage. Glyphosate was applied at rates 1/3, 1/6, 1/12, 1/24, and 1/48 the use rate for spring wheat desiccation on 10 Sept. 2004 with a CO2 pressurized sprayer operated at 280 L/ha and 276 kPa. The amount of a.m.S added to the spray solution was also reduced accordingly. Following harvest, samples from each plot were placed into cold storage until the following March. A subsample from each plot was slowly warmed to initiate sprout formation. Remaining samples were cut into 57-g pieces, dusted with a seed piece treatment, and stored at 18 °C with about 90% RH until planted. Plots consisted of two 3-m rows at 91 cm-row spacing with a border row on each side and three spacer plants between plots. The trial was arranged as a randomized complete block with four replications. Plots were desiccated on 12 and 19 Sept. and harvested 11 Oct. Tubers were hand-graded shortly after harvest. Results indicated that glyphosate at 70 g ae/ha or more inhibited tuber budbreak by 75% or more compared to untreated. In the field, injury was observed as delayed emergence and, in several instances, no plants emerged. Total yield for `Red Lasoda' was 34.8 Mg/ha for the untreated, which was significantly greater than glyphosate treatments of 280, 140, and 70 g ae/ha. `Russet Burbank' total yield was considerably less at 23.5 Mg/ha for the untreated. Both the untreated and glyphosate at 18 g ae/ha had significantly greater total yields compared with glyphosate treatments of 280, 140, and 70 g ae/ha.

Glyphosate Drift

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.

Nitrogen Fertiliser

Thirteen field trials were conducted on ferrosols and tenosols in Tasmania to assess the response of potatoes (Solanum tuberosum L., cv. Russet Burbank) to basal (up to 250 kg/ha) and topdressed (up to 100 kg/ha) nitrogen fertiliser. Economic yield responses to basal nitrogen were obtained at 9 sites. Topdressing did not increase yield compared with equivalent rates of basal nitrogen, and often failed to compensate for a lack of nitrogen applied at planting. This lack of response may reflect the inability of the potato crop to make use of nitrogen applied during tuber bulking. Nitrogen fertiliser decreased tuber specific gravity at several sites. The effects of nitrogen on misshapen tubers, bruising susceptibility, crisp colour and hollow heart were inconsistent and often of no practical importance. However, at 2 sites, nitrogen fertiliser increased yields of misshapen tubers at the expense of processing tuber yields. At 1 of these sites, nitrogen topdressing decreased the yield of misshapen tubers. Otherwise, topdressing had similar effects on tuber quality to those of basal nitrogen. Growers should fertilise with nitrogen to optimise their yields. Optimum rates were greater in paddocks that had been continuously cropped for more than 10 years (average rate 193 kg/ha), than in those that had been in pasture (average rate 48 kg/ha).

Effect On Yield

Whole seed potato tubers in the size ranges 35-100 g, 101-150 g and 35-150 g were compared with cut seed and a mixed run grade of both whole 35-100 g tubers and cut seed, at within row spacings of 25 and 33.3 cm in rows 81.3 cm wide, at Healesville, Ballarat and Warragul districts in 1986-87 and 1987-88. Whole 35-250 g tubers and 40 cm within row spacing were also included in experiments at Healesville during the 2 seasons. The mean total tuber yield from planting whole 35-150 g tubers (47.9 t/ha) was significantly higher than from planting Run grade seed [44.9 t/ha, 1.s.d. (P=0.05)=2.0]. Yields of 35-100 g and 101-150 g tubers were also significantly higher with plantings of whole seed compared with Cut or Run seed. The mean yield of tubers >250 g was significantly higher from planting Run grade seed (12.0 t/ha) than whole 35-150 g tubers [9.7 t/ha, 1.s.d. (P=0.05)=1.8]. Increasing the within row spacing from 25 to 33.3 or 40 cm significantly increased the yield of tubers >250 g and significantly reduced the yield of 101-150 g tubers. The effect on yield of 35-100 g, 151-250 g tubers and total tuber yield was variable. The mean multiplication rate (total yield/seed planting rate) from plantings of 101-150 g whole seed was significantly lower than from plantings of Cut and Run seed but was increased significantly with plantings of whole 35-100 g seed. Increasing the within row spacing significantly increased the multiplication rate and values from 1 environment were 17.2 at 25 cm, 22.2 at 33.3 cm and 24.6 at 40 cm [l.s.d. (P=0.05)=1.5]. The mean number of tubers per plant was significantly higher from plantings of whole seed (8.0-9.1) than from Cut or Run grade seed [6.8-7.1, 1.s.d. (P=0.05)=0.4] and was increased significantly by increasing the within row spacings from 25 to 33.3 or 40 cm.

Yield Responses

This study examined the influence of irrigation, soil nitrogen (N) levels and seed piece spacing on the yields and tuber size distribution of Norland, Russet Burbank and Shepody potatoes over three seasons at two sites in central Saskatchewan. The crops were grown under standard irrigated conditions or on dryland with in-row spacings of 15, 23 or 30 cm and total N levels of 200 or 300 kg ha−1 as either preplant or split applications. Irrigation greatly enhanced yields of all tuber size categories in the drier years but had less effect if seasonal precipitation reached or exceeded normal levels. Smaller size tubers formed a greater proportion of the total yield in crops exposed to drought stress. Norland was less affected by drought than the later-maturing cultivars. Yield responses to N were limited to situations where soil moisture was abundant or crop demand for nutrients was increased by close in-row spacings. Close in-row spacing increased total yields in some cases, while in others it resulted in a reduction in tuber size with little effect on overall yields. Yields for the cultivar Norland were less affected by seed piece spacing than yields for Russet Burbank or Shepody. Key words: Solanum tuberosum, drop seed, spacing, fertility

Crop Injury

Sulfentrazone was applied POST at 13, 26, or 53 g ai/ha alone or in combination with metribuzin at 280 or 420 g ai/ha in field trials conducted with ‘Russet Burbank’ potatoes in 2002 to 2004. Sulfentrazone alone provided less than 84% redroot pigweed, common lambsquarters, and kochia control, although control usually improved to 90% or greater when metribuzin was included. Hairy nightshade control reached 90% only when the highest rates of both herbicides were applied in combination. Sulfentrazone alone did not provide any volunteer oat control, whereas control was 85% when the highest metribuzin rate was included. Potato crop injury, consisting of chlorosis, interveinal blackening of the leaves, eventual necrosis, leaf malformation, and plant stunting, increased as the sulfentrazone rate increased. In contrast, injury decreased as metribuzin rate increased from 0 to 420 g/ha, when averaged across sulfentrazone rates. Reduction in injury levels and increased weed control translated to improved tuber yields as metribuzin rate increased. However, when sulfentrazone was combined with the highest metribuzin rate, potato injury was still relatively high at 26 and 18% at 1 and 4 wk after treatment, and acceptance of sulfentrazone applied POST with metribuzin by potato growers is unlikely.

Potato (Solanum tuberosum) selections (clones and commercial cultivars) were examined for resistance to root galling, caused by the powdery scab pathogen Spongospora subterranea f. sp. subterranea in seven field trials conducted between 2003 and 2007 in the states of Washington and Idaho. Four industry reference cultivars—Shepody, Russet Burbank, Russet Ranger, and Umatilla Russet—were used as susceptible standards. Every year, selections less susceptible than the standards were considered resistant and progressed to the next season. Selections that did not demonstrate resistance in at least two consecutive trials were discarded. Eight potato selections were more resistant to root galling than the susceptible standards in two or more trials: PA98NM38-1 was more resistant than the susceptible standards in 5 of 5 trials, PO94A009-10 in 4 of 5 trials, PA95B2-4 and PA98N5-2 in 3 of 5 trials, POR00HG5-1 in 2 of 5 trials, PO94A009-7 in 3 of 4 trials, PO94A012-2 in 2 of 3 trials, and Summit Russet in 2 of 2 trials. POR00HG5-1 has Solanum hougasii in its ancestry, while the other selections have the Mexican wild species Solanum bulbocastanum and the commercial cultivar Summit Russet appearing in their ancestry. Summit Russet is the most plausible source of resistance.

The Mean

The efficacy of metalaxyl-m (Ridomil Gold 480EC) and phosphite (Phostrol) applied at planting in-furrow against pink rot (Phytophthora erythroseptica) of potato (Solanum tuberosum) ‘Shepody’ and ‘Russet Burbank’ was evaluated in field trials conducted in 2005 and 2006 in Florenceville, New Brunswick, Canada. Inoculum made from a metalaxyl-m-sensitive isolate of P. erythroseptica from New Brunswick was applied either in-furrow as a vermiculite slurry at planting or as a zoospore drench in soils adjacent to potato plants in late August. After harvest, the number and weight of tubers showing pink rot symptoms were assessed and expressed as percentages of the total tuber number and total weight of tubers. Metalaxyl-m applied in-furrow was significantly more effective against pink rot than phosphite. The mean percentage of diseased tubers as a percentage of total tuber weight was 1.5% (2005) and 1.2% (2006) for metalaxyl-m-treated plots and 9.6% (2005) and 2.8% (2006) for phosphite-treated plots, a percentage similar to that obtained in inoculated control plots with no fungicide treatment. The mean percentage of diseased tubers expressed as a percentage of the total number of tubers was 1.7% (2005) and 1.3% (2006) for metalaxyl-m-treated plots and 10.1% (2005) and 3.1% (2006) for phosphite-treated plots. Disease incidence was significantly higher using the late-season inoculation technique (respective means in 2005 and 2006 were 9.9 and 3.8% diseased tubers, by weight, and 10.6 and 3.9%, by number) than with the in-furrow inoculation method (respective means in 2005 and 2006 were 3.3 and 0.7% by weight, and 3.7 and 1.3%, by number). The potato cv. Shepody was significantly more susceptible to pink rot (9.9 and 3.3% diseased tubers, by weight, in 2005 and 2006, respectively, and 10.6 and 3.9%, by number) than Russet Burbank (respective means in 2005 and 2006 were 3.4,% and 1.2%, by weight, and 3.7,% and 1.2%, by number). Our findings indicate that metalaxyl applied in-furrow at planting is a viable option for control of pink rot caused by metalaxyl-sensitive strains of P. erythroseptica, whereas phosphite was ineffective.
