Growth and pathogenicity characteristics of Ralstonia solanacearum strain RS1100 in long-term stationary phase cultureJournal of Plant Diseases and Protection - Tập 117 - Trang 156-161 - 2016
Y.-J. Zhu, R.-F. Xiao, B. Liu
Nonsporulating gram-negative bacteria remain metabolically active and also develop increased resistance to a variety of environmental stresses after exponential growth has stopped and cells enter stationary phase. Ralstonia solanacearum is a nonsporulating gram-negative soil-borne pathogen that causes lethal wilt diseases of many plants around the world. Its growth and pathogenicity characteristic...... hiện toàn bộ
Effect of xanthan gum and allicin as elicitors against Bipolaris sorokiniana on barley in field experimentsJournal of Plant Diseases and Protection - Tập 115 - Trang 104-107 - 2016
N. Antoniazzi, C. Deschamps, E. E. Bach
Barley spot blotch, caused by the fungus Bipolaris sorokiniana (Sacc.) Shoem., leads to decreases in productivity and affects beer quality. The objective of the present study was to validate findings in laboratory and greenhouse experiments on biochemical responses that occur in malting barley cultivar BRS 195 when treated with elicitors of resistance (xanthan gum and allicin) and with the fungici...... hiện toàn bộ

In this paper, we evaluate the use of an electronic nose (EN) containing 13 conducting polymer gas sensors to discriminate between patterns of volatile organic compounds (VOCs) emitted by plants. The VOC patterns examined were produced by tomato, cucumber and pepper plants under both healthy and infected or infested conditions. Leaves from the plants were subjected to mechanical damage or pest and...... hiện toàn bộ
Effects of insect net coverage in field vegetables on pests, diseases, natural enemies, and yieldJournal of Plant Diseases and Protection - Tập 129 - Trang 1401-1415 - 2022
Elias Böckmann
With the reduced availability of effective plant protection products, alternative control measures gain importance. Insect net covers are a promising tool in this regard, because they can reduce pest damage on crop by exclusion of pests. However, as under practical conditions, most crop net covers need to be removed several times during a crop cycle to manage weeds and apply fertilizers, a complet...... hiện toàn bộ
Molecular identification and characterization of groundnut bud necrosis virus and its associated thrips vector from Gerbera jamesonii in IndiaJournal of Plant Diseases and Protection - Tập 128 - Trang 673-683 - 2021

Gerbera is an important cut flower crop popular throughout the world. In summer months of 2016, gerberas grown in polyhouses of RHREC, GKVK, Bengaluru, Karnataka, India showed heavy infestation of thrips and displayed symptoms of viral infections. Infected plants displayed irregular chlorotic or necrotic spots or blotches, necrosis of veins, bronzing, crinkling and deformations of leaves; necrotic...... hiện toàn bộ
Farmers' knowledge, perceptions, and farm-level management practices of citrus pests and diseases in MoroccoJournal of Plant Diseases and Protection - Tập 128 - Trang 1213-1226 - 2021
Rachid Lahlali, Manal Jaouad, Alieu Moinina, Fouad Mokrini, Zineb Belabess
This paper documents pest management practices adopted by citrus farmers in two of the citrus-growing regions in Morocco. The survey data propose possible recommendations to ensure sustainable pest management strategies. By variety, the surface area occupied by the Navel and Maroc-late represented 25% and 23%, respectively. 54% of the citrus farmers used certified sour orange rootstocks. 79% of fa...... hiện toàn bộ
