“…Among other options, the synergistic use of green manures, cover crops, solarisation, nematicidal plants, etc., in complement with plant resistance may become realistic . The current challenge for pathogen control is to design new cropping systems that allow incorporation of alternative techniques with the use of R genes, in order to diversify the selection pressures on the nematode populations while satisfying the farmer constraints . Obviously, this challenge will open new research questions at the crossroads of various disciplines from plant to agricultural sciences, as well as at the crossroads of experimental approaches varying from very controlled experiments to field surveys.…”

Host genetic resistance to root-knot nematodes,Meloidogynespp., in Solanaceae: from genes to the field

et al. 2015

Root-knot nematodes (RKNs) heavily damage most solanaceous crops worldwide. Fortunately, major resistance genes are available in a number of plant species, and their use provides a safe and economically relevant strategy for RKN control. From a structural point of view, these genes often harbour NBS-LRR motifs (i.e. a nucleotide binding site and a leucine rich repeat region near the carboxy terminus) and are organised in syntenic clusters in solanaceous genomes. Their introgression from wild to cultivated plants remains a challenge for breeders, although facilitated by marker-assisted selection. As shown with other pathosystems, the genetic background into which the resistance genes are introgressed is of prime importance to both the expression of the resistance and its durability, as exemplified by the recent discovery of quantitative trait loci conferring quantitative resistance to RKNs in pepper. The deployment of resistance genes at a large scale may result in the emergence and spread of virulent nematode populations able to overcome them, as already reported in tomato and pepper. Therefore, careful management of the resistance genes available in solanaceous crops is crucial to avoid significant reduction in the duration of RKN genetic control in the field. From that perspective, only rational management combining breeding and cultivation practices will allow the design and implementation of innovative, sustainable crop production systems that protect the resistance genes and maintain their durability.

“…Several agroecological techniques are known to affect RKNs (Zasada et al 2010;Collange et al 2011): sanitation, soil tillage, organic amendment, nematicidal green manure, biological control, heat-based methods, and plant resistance etc. Each of these techniques is only partly effective, necessitating their combination, which further complicates their adoption on farms where space available under shelters for non-commercial practices is very limited (Collange et al 2014). Breeders are mostly focusing on the introgression of resistance genes (R-genes) into commercial cultivars or rootstocks, a strategy with several limitations.…”

Root-knot nematodes are causing serious economic losses of vegetable production. Actual agroecological control solutions are not effective enough to control this pest or are difficult to implement in farms. There is little knowledge on the use of crops to trap nematodes in protected cultivation systems. Therefore, we tested a resistant pepper as a trap crop for root-knot nematodes over 4 years in a commercial farm and an experimental station in Southern France. The effects of pepper trap crop on plant damages and soil infestation were compared with a sorghum cover crop. We also surveyed 28 local vegetable farmers for their interest concerning the possible use of the pepper trap crop. Our results show that nematode infestation of the soil decreased by 99 and 80%after the first and second implementation of the trap crop. The gall index measured on Swiss chard decreased from 2.5 to less than 1 after 4 years. Respectively, 21 and 36 % of farmers found the cropping system completely and partially acceptable. The most interested farmers were those having sufficient labor and available land in summer. Farmer criticisms were higher nursery costs and planting duration, versus sorghum. Overall, this is the first design of a cropping system using a resistant cultivar as a dead-end trap crop for root-knot nematodes. The process used, moving from a genetic construct to agronomic innovation through an interdisciplinary and participatory approach, holds promise for scientists seeking new integrated pest management approaches to increase the sustainability of agriculture

“…To control lettuce white mould disease agent in Turkey, effective control measures are currently not available. Use of resistant cultivars, solarisation, drip irrigation, crop rotation and soil disinfections were major cultural practices offered for disease management (Collange et al, 2014). However, the fungicides registered against the fungal disease agent do not adequately control the diseases (Zhu et al, 2016).…”

In this study, biocontrol efficiency of endophytic bacterial isolates obtained from the leaf lettuce (Lactuca sativa L.) healthy plants was investigated against white mould disease agent Sclerotinia sclerotiorum in vitro and in vivo conditions. Antagonistic efficiency of endophytic bacterial isolates was determined to inhibit mycelial growth and sclerotial germination, suppress disease incidence caused by S. sclerotiorum. A total of 48 endophytic bacterial isolates were isolated from different tissues of lettuce healthy plants. Mycelial growth and germination of sclerotia of S. sclerotiorum in vitro inhibited 18 bacterial isolates. Bacillus subtilis and B. amyloliquefaciens isolates were found to be the most efficient ones, which significantly inhibited the mycelial growth by 68.1-83.1%, germination of sclerotia by 82.7-89.6% and suppressed disease incidence by 55.7-75% caused by S. sclerotiorum. In addition, the fungal mycelium close to the inhibition zone in dual culture was denser and darker in colour. B. subtilis and B. amyloliquefaciens isolates caused significant morphological alterations in hyphae such as hyphal shrivelling and perforation close to the inhibition zone in dual culture. Significant suppression in the mycelial growth, sclerotial germination and disease incidence caused by endophytic bacterial isolates indicate that isolates of B. subtilis and B. amyloliquefaciens could be considered as possible biocontrol agents against soil-borne fungal diseases.
