“…Traditionally, rye has been used by Quebec potato growers as a rotation crop. Rye was previously recognized to be a good host for P. penetrans (Bélair et al 2002;Dunn and Mai 1973;Olthof 1980;Thies et al 1995). Our results demonstrated that rotation with rye increased P. penetrans population densities in soil and, in addition, reduced potato yields.…”

“…Many studies have shown that pearl millet hybrids are poor hosts of P. penetrans under greenhouse and field conditions (Ball-Coelho et al 2003;Bélair et al 2002Bélair et al , 2005Jagdale et al 2000). However, some studies have shown that grain hybrids were less effective than CFPM 101 (a forage hybrid commonly used by growers) in reducing P. penetrans populations and improving potato yields (Ball-Coelho et al 2003;Bélair et al 2005).…”

“…Unfortunately, rye is a good host of P. penetrans (Bélair et al 2002;Dunn and Mai 1973;Olthof 1980;Thies et al 1995); therefore, when used as a rotation crop, rye may increase nematode damage and yield losses on subsequent crops. Soil fumigation with chemicals such as metam sodium is commonly used in Quebec potato production to control P. penetrans populations and increase potato yields.…”

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

“…Different species of weeds have been recognized as host plants for Pratylenchus spp. in diverse regions of the world, contributing to an increase of nematode populations in the soil, thus constraining the establishment of agricultural cultures (Kutywayo and Been, 2006;Bélair et al, 2007;Smiley et al, 2014). In this context, this work aimed to assess the reproductive capacity of P. zeae in different species of weeds.…”

-Weeds can be hosts of root-lesion nematode (Pratylenchus spp.), maintaining or increasing their population in the soil. The objective of this study was to evaluate the reaction of 25 weeds species to the nematode Pratylenchus zeae. The weed plants were individually inoculated with 1,000 individuals of P. zeae and maintained in a greenhouse for 90 days. After this period, eggs and nematodes were extracted, quantified, and the reproduction factor (RF = final population/initial population) was calculated. All tested weeds were susceptible (RF>1) to P. zeae, and the species Brachiaria decumbens, Rhynchelytrum repens, Digitaria insularis, D. horizontalis, B. brizantha were the most susceptible to this parasite.Keywords: invasive plants, susceptibility, lesion nematode, parasite. RESUMO -As plantas daninhas podem ser hospedeiras de nematoides das lesões (Pratylenchus spp.), mantendo ou elevando sua população no solo. O objetivo deste trabalho foi avaliar a reação de 25 espécies de plantas daninhas a Pratylenchus zeae. As plantas daninhas foram individualmente inoculadas com 1.000 espécimes de P. zeae e mantidas em casa de vegetação por 90 dias. Após esse período, os ovos e nematoides foram extraídos e quantificados, sendo calculado o fator de reprodução (FR = população final/população inicial

Carrot yield (Daucus carota) and population levels of the root-lesion nematode Pratylenchus penetrans and the northern root-knot nematode Meloidogyne hapla were measured in five rotation crops and in subsequent carrot crops at three field sites (1998-1999, 1999-2000, and 2000-2001). Total and marketable carrot yields averaged over the three sites did not differ in the crop sequences but there was a difference among sites. The total yields at sites 1, 2, and 3 were 77.86, 68.12, and 30.33 tonnes ha-1, respectively. Marketable yields were 59.04, 60.62, and 24.11 tonnes ha-1 at sites 1, 2, and 3, respectively. The lower yields were attributed primarily to less rainfall during July and August in 2001, and possibly to northern root-knot nematodes that were more prevalent at site 3. Mean levels of root-lesion nematodes in soil were highest (2690 nematodes kg-1) in carrot that followed timothy (Phleum pratense cv. Common), lowest (1100 nematodes kg-1) in carrots that followed marigold (Tagetes erecta cv. Crackerjack), and intermediate after barley (Hordeum vulgare cv. Chapais), pearl millet (Pennisetum glaucum cv. Millet 101), and annual ryegrass (Lolium multiflorum cv. Lemtal). Root-lesion nematode populations were also lower in marigold than in the other crops. Northern root-knot nematodes were not detected in rotation crops. The study indicated that carrot yields did not differ irrespective of the previous crop, but root-lesion nematode populations in soil at harvest were highest in carrots that followed timothy and lowest in carrots that followed marigolds. Population levels of root-knot nematodes in carrots did not differ among the crop sequences.Le rendement de la carotte (Daucus carota) et l’importance des populations du nématode des lésions de racines Pratylenchus penetrans et du nématode cécidogène du nord Meloidogyne hapla ont été mesurés dans cinq cultures utilisées en rotation et dans les cultures subséquentes de carottes à trois sites en champ (1998-1999, 1999-2000 et 2000-2001). La moyenne des rendements totaux et commercialisables pour les trois sites ne différait pas en fonction de la séquence des cultures, mais différait en fonction des sites. Les rendements totaux aux sites 1, 2 et 3 ont été respectivement de 77,86, 68,12 et 30,33 tonnes ha-1. Les rendements commercialisables ont été respectivement de 59,04, 60,62 et 24,11 tonnes ha-1 aux sites 1, 2 et 3. Les rendements les plus faibles ont été principalement attribués à des précipitations moins importantes au cours des mois de juillet et août 2001, et peut-être aussi à la présence du nématode cécidogène du nord au site 3. Les populations moyennes du nématode des lésions de racines ont été plus élevées (2690 nématodes kg-1) dans la carotte qui suivait la phléole (Phleum pratense cv. Common), plus faibles (1100 nématodes kg-1) dans la carotte qui suivait le tagète (Tagetes erecta cv. Crackerjack) et intermédiaires après l’orge (Hordeum vulgare cv. Chapais), le mil perlé (Pennisetum glaucum cv. Millet 101) et le ray-grass d’Italie (Lolium multiflorum cv....
