A field study was conducted in Quebec to determine the effect of crop rotation with grain pearl millet (Pennisetum glaucum) on Pratylenchus penetrans populations and the subsequent yields of two potato cultivars (Solanum tuberosum) when compared with rye and continuous potato with and without fumigation. Pearl millet had a suppressive effect on P. penetrans populations compared with rye but not as much as continuous potato with fumigation. In 2002, total potato yields of cv. Superior and cv. Hilite Russet were negatively correlated with P. penetrans densities at harvest. Total yields of potato cv. Superior were increased by 123 and 229% following pearl millet and fumigation, respectively, compared with rye. Total yields of potato cv. Hilite Russet increased by 26 and 17% following pearl millet and fumigation. Grain pearl millet CGPM H-1 reduced P. penetrans densities and improved potato yields in Quebec.L’effet d’une rotation avec le millet perlé grain (Pennisetum glaucum) sur les populations de Pratylenchus penetrans et les rendements subséquents de deux variétés de pommes de terre (Solanum tuberosum) a été comparé à des rotations avec le seigle, la pomme de terre et la pomme de terre suivie d’une fumigation. Le millet a eu un effet suppressif sur les populations de P. penetrans comparativement au seigle, mais à un degré moindre que la fumigation. En 2002, les rendements de pommes de terre cv. Superior et cv. Hilite Russet étaient négativement corrélés avec les densités à la récolte du P. penetrans. Les rendements de pomme de terre cv. Superior ont été accrus respectivement de 123 et de 229 % après la culture de millet et la fumigation comparativement au seigle. Les rendements de pomme de terre cv. Hilite Russet ont été accrus respectivement de 26 et de 17 % après la culture de millet perlé et la fumigation. Le millet perlé grain CGPM H-1 a réduit les densités du P. penetrans et accru les rendements de pommes de terre au Québec

“…A study by Jagdale et al (2000) reported no effect on tobacco yield due to millet rotation, compared with the winter rye fumigated or non-fumigated control plots. Bélair et al (2004) observed that tobacco yields in plots previously planted to forage millet or grain millet were significantly higher than those of the rye non-fumigated control, and were similar to those of the rye-fumigated plots. Ball-Coelho et al (2003) and more recently Bélair et al (2005), who used potato as the associated crop, reported similar results.…”

“…In addition, comparisons based on the non-fumigated winter rye plots show a yield increase of 19 to 70% in tobacco following forage millet, tobacco following grain millet had a yield increase of 18 to 65% and tobacco following winter rye with fumigation showed a yield increase of 14 to 51%.

“…It has been reported that pearl millet (Pennisetum glaucum L.) used as a rotation crop will facilitate the reduction of P. penetrans population (Jagdale et al 2000;Ball-Coelho et al 2003;Bélair et al 2004). These studies have involved the planting of forage or grain hybrids of pearl millet developed at Agriculture Environmental Renewal Canada (AERC Inc.), Delhi, Ontario, in rotation with tobacco or potato.…”

. 2006. Pearl millet as a rotation crop with flue-cured tobacco for control of root-lesion nematodes in Ontario. Can. J. Plant Sci. 86: 1265-1271. In Ontario, flue-cured tobacco (Nicotiana tabacum L.) growers routinely fumigate their soils to control root-lesion nematodes (Pratylenchus penetrans Cobb). Studies suggest that planting pearl millet (Pennisetum glaucum L.) as a rotation crop may control the nematodes; winter rye (Secale cereale L.), the crop commonly grown in rotation with tobacco, is susceptible to the nematodes. In 2002, plots of forage millet (var. CFPM 101), grain millet (var. CGPMH-1) and winter rye were established at three sites and in 2003, tobacco was grown at these sites in non-fumigated plots where the rotation crops grew, except for a winter rye/fumigation treatment. The goal was to evaluate P. penetrans populations and tobacco yield and quality in the millet rotations relative to the traditional rye-fumigation system. In 2002, initial P. penetrans populations assessed in the spring were similar for all treatments; however, the final populations and consequently the ratios of final populations/initial populations (Pf/Pi) consistently differed among treatments. The Pf/Pi ratios ranged from 0.07 to 0.79 for forage millet, from 0.18 to 0.94 for grain millet and from 2.33 to 21.65 for rye. In 2003, P. penetrans populations in tobacco plots previously cropped to either type of millet were comparable with those detected in fumigated winter rye plots. Compared with tobacco following rye without fumigation, tobacco yield was 14 to 51% higher following rye with fumigation, 19 to 70% higher following forage millet and 18 to 65% higher following grain millet. Grade index was unaffected. Results indicate that pearl millet offers an alternative to fumigants for the suppression of P. penetrans population and provides equivalent gross returns. hiver à trois endroits puis, l'année suivante, ont cultivé du tabac sur les mêmes sites sans fumiger le sol, sauf dans un cas, pour le seigle d'hiver. L'objectif était d'évaluer la population de P. penetrans ainsi que le rendement et la qualité du tabac poussant sur les parcelles où l'on avait cultivé du millet, comparativement à ceux obtenus avec le régime usuel seigle/fumigation. En 2002, la population de P. penetrans initialement évaluée au printemps était similaire pour tous les traitements; cependant, la population finale et le ratio entre la population finale et initiale (Pf/Pi) différaient constamment d'un traitement à l'autre. Le ratio Pf/Pi varie de 0,07 à 0,79 pour le millet fourrager, de 0,10 à 0,94 pour le millet grainier et de 2,33 à 21,65 pour le seigle. En 2003, la population de P. penetrans dans les parcelles de tabac sur lesquelles on avait antérieurement cultivé une ou l'autre sorte de millet était comparable à celle des parcelles de seigle fumigées. Comparativement au rendement obtenu sur les parcelles de seigle non fumigées, le rendement du tabac augmente de 14 à 51 % après fumigation des parcelles de seigle, de 19 à 70 % après la culture du mi...

. 2010. Chemical and mechanical weed management strategies for grain pearl millet and forage pearl millet. Can. J. Plant Sci. 90: 371Á381. There are limited options for controlling weeds in grain and forage pearl millet production in eastern Canada. Field studies were conducted near Quebec City in 2005 and 2006 to evaluate the effectiveness of herbicidal treatments (s-metolachlor/benoxacor and pendimethalin) and harrowing to control weeds and maximize yield in grain and forage pearl millet cultivation. s-Metolachlor/benoxacor and pendimethalin were applied either preemergence or early postemergence at the full dose recommended for corn and at half of that dose. Harrowing was evaluated at the three-and the five-leaf stage of pearl millet. In both types of pearl millet, s-metolachlor/ benoxacor applied preemergence reduced plant density and yield. All other herbicidal treatments caused no visual injury to pearl millet and adequately controlled annual weeds, leading to grain and forage yields similar or slightly lower than those of the hand-weeded control. Better barnyard grass control resulted from early postemergence application of s-metolachlor/ benoxacor compared with that of pendimethalin. Preemergence application of pendimethalin was more effective at controlling barnyard grass than early postemergence application. Harrowing was not effective at controlling annual weeds, resulting in important millet yield losses. Les herbicides s-me´tolachlore/benoxacor et pendime´thaline ont e´te´applique´s en pre´leve´e ou en postleve´e haˆtive a`la pleine dose et a`la moitie´de la dose recommande´e dans le maı¨s-grain, alors que le passage de la herse-e´trille a e´te´e´tudie´aux stades trois et cinq feuilles du millet perle´. Dans les deux types de millet perle´, le s-me´tolachlore/benoxacor applique´en pre´leve´e a re´duit de fac¸on significative le peuplement de la culture, re´sultant en des baisses conside´rables de rendement. Tous les autres traitements chimiques n'ont pas cause´de symptoˆmes visibles sur le millet perle´et ont procure´un de´sherbage ade´quat, re´sultant en des rendements en grain et en fourrage e´quivalents ou le´ge`rement infe´rieurs aux rendements obtenus avec le te´moin de´sherbe´a`la main. En postleve´e haˆtive, le s-me´tolachlore/benoxacor a re´prime´l'e´chinochloa pied-de-coq plus efficacement que la pendime´thaline. Les applications de pre´leve´e de pendime´thaline ont mieux re´prime´l'e´chinochloa piedde-coq que les applications de postleve´e haˆtive. Le de´sherbage me´canique a peu re´prime´les mauvaises herbes annuelles, ce qui a provoque´d'importantes pertes de rendement.
