The response of dry bean (Phoseolus vulgaris L.), buckwheat (Fagopyrum esculentum Moench.), potato (Solanum tuberosum L.) and sunflower (Helianthus annuus L.) to soil residues of ethametsulfuron was determined. Buckwheat and sunflower exhibited moderate to severe injury 4 wk after planting; navy bean, buckwheat, sunflower and potato yields were unaffected in the cropping year after ethametsulfuron application.

The effect of flumetsulam on several vegetable crops grown following soybean was investigated over a 4-yr period. Flumetsulam was applied preplant incorporated to soybean at 0, 70 and 140 g a.i. ha−1 from 1992 to 1994. In trials 1 yr after flumetsulam application, cabbage (Brassica oleracea var. capitata), potato (Solanum tuberosum L.), tomato (Lycopersicon esculentum L.), and pepper (Capsicum annuum L.), showed visual injury symptoms and reduced yields in 1993, while only cabbage showed visual injury symptoms and reduced yields in 1994 and 1995. Cucumber (Cucumis sativus) showed injury symptoms only in 1993 and had no yield reduction. Cabbage also showed visual injury and reduced yields 2 and 3 yr following a 1992 flumetsulam application. Broccoli (Brassica oleracea var. italica) and cauliflower (Brassica oleracea var. botrytis) showed visual injury symptoms in 1995, 3 yr after flumetsulam application. Generally, crop tolerance decreased linearly as application dose increased from 0 to 140 g ha−1. Minor visual injury symptoms did not correspond with a reduced yield. Injury was most severe on sites with the lowest soil pH values. Based on these studies, effects of flumetsulam from normal use rates (70 g ha–1) will carry over to injure-sensitive crops like cabbage, in the rotation for up to 3 yr, especially in low pH soils (pH 6.1 or less). Otherwise, a 22-mo planting interval is adequate to protect other vegetable crops in the rotation from injury and yield reductions. Key words: Crop injury, herbicide carryover, flumetsulam, yield

Pageni, B. B., Lupwayi, N. Z., Larney, F. J., Kawchuk, L. M. and Gan, Y. 2013. Populations, diversity and identities of bacterial endophytes in potato ( Solanum tuberosum L.) cropping systems. Can. J. Plant Sci. 93: 1125–1142. Most plants host endophytic bacteria, but their identities and functions are usually unknown. Bacterial endophytes associated with potato grown after dry bean (Phaseolus vulgaris L.) or wheat (Triticum aestivum L.) were isolated, quantified and identified in a field study that compared crop rotations (3 to 6 yr in length) and soil management (CONV, conventional; CONS, conservation) for dry bean, potato, sugar beet (Beta vulgaris L.) and spring wheat. Populations of culturable endophytes ranged from 2.83×103 to 7.65×103 colony-forming units g−1 of root dry matter. The populations and diversity of the endophytes were greater with CONS than CONV soil management, and tended to be greater in longer than shorter rotations. The community structures of the endophytes were different between CONV and CONS soil management. A terminal-restriction fragment length polymorphism assay targeting the 16S rRNA gene, and its sequencing, showed that CONS management systems contained more Proteobacteria than CONV management systems, and vice-versa for Acidobacteria. Bacteriodetes were found only in long CONS rotations. This phylogenetic characterization of potato endophytes is important for further studies on their effects on the host plants.

Pageni, B. B., Lupwayi, N. Z., Akter, Z., Larney, F. J., Kawchuk, L. M. and Gan, Y. 2014. Plant growth-promoting and phytopathogen-antagonistic properties of bacterial endophytes from potato (Solanum tuberosum L.) cropping systems. Can. J. Plant Sci. 94: 835–844. Endophytes are microorganisms that live within a plant without harming it. Bacterial endophytes were isolated from roots of potatoes (Solanum tuberosum L.) grown under different rotations (3 to 6 yr in length) and soil management (CONV, conventional; CONS, conservation) in irrigated cropping systems with dry bean (Phaseolus vulgaris L.), sugar beet (Beta vulgaris L.) spring wheat (Triticum aestivum L.) and timothy (Phleum pratense L.). The endophytes were characterized for nitrogen fixation potential, phytohormone production and phytopathogen-antagonistic properties. The nitrogen-fixing nitrogenase (nifH) gene was detected in potato grown in all rotations, presumably partly because the soil in all rotations contained Rhizobium leguminosarum bv. phaseoli from the dry bean phase. Sequence analysis revealed that it was homologous to the genes found in Burkholderia, Azospirillum, Ideonella, Pseudacidovorax and Bradyrhizobium species. Indole acetic acid (IAA) hormone production by endophytes isolated from potato grown under CONS management was 66% greater than that those isolated from potato grown under CONV management, and tended to be greater in longer than shorter rotations. When 12 endophytes were inoculated to dry bean, four increased shoot biomass by 27–34%, and six increased total (shoot+root) biomass by 25% on average. Endophytes from the longer CONS rotations (4–6 yr) resulted in significantly higher (by 9%) shoot biomass than the shortest CONS (3 yr) rotation. Six of 108 endophyte isolates exhibited antagonistic properties (reduced pathogen biomass by 12 to 58% in dual culture assays in liquid media) against potato pathogens Pectobacterium atrosepticum, Fusarium sambucinum and Clavibacter michiganensis subsp. epedonicus. All the six isolates were from CONS soil management. Therefore, the benefits of long rotations, with their associated CONS soil management, to crop productivity in these irrigated cropping systems probably include nutritional (biological nitrogen fixation and IAA hormone production) and disease-control benefits imparted by endophytic bacteria.
