Inoculum potential of Sclerotinia sclerotiorum sclerotia depends on isolate and host plant

plant_pathology_feb18.jpgAndrew Taylor, Emma Coventry, Claire Handy, Jon S West, Caroline S Young and John P Clarkson

The soilborne fungus Sclerotinia sclerotiorum infects many important crop plants. Central to the success of this pathogen is the production of sclerotia, which enables survival in soil and constitutes the primary inoculum. This study aimed to determine how crop plant type and S. sclerotiorum isolate impact sclerotial production and germination and hence inoculum potential. These findings, once further validated in field trials, could be used to inform future crop rotation decisions.

Handbook of Pest Management in Organic Farming - Pest Management in Organic Field vegetables in Temperate Areas

Handbook of Pest Management in Organic FarmingDaniel, Claudia; Collier, Rosemary; Niggli, Urs and Koller, Martin (2018) Pest Management in Organic Field vegeatables in Temperate Areas In: Vacante, Vincenzo and Kreiter, Serge (Eds.)

Preventative measures and the creation of resilient growing systems are key parts of pest management practice in organic field vegetable production.
Soil improvement, crop rotation, site selection, habitat management, variety choice, timing of plant and plant spacing are all considered before planting in order to avoid the most detrimental pest problems.
For some crops (eg. cabbage and carrot (Finch and Collier, 2000)), a holistic pest control strategy, which combines preventative and direct control measures, is available, however in lettuce production, pest management under organic conditions still relies heavily on direct pest control measures.
Due to the huge variety of vegetable crops and their associated pest insects, specific tailored approaches are necessary.
Within this chapter, strategies and methods of pest control in organic field vegetable production that are available currently are described.

A laboratory simulation of Arabidopsis seed dormancy cycling provides new insight into its regulation by clock genes and the dormancy‐related genes DOG1, MFT, CIPK23 and PHYA

Footitt, S., Ölcer‐Footitt, H., Hambidge, A. J., Finch‐Savage, W. E

plant_cell__env_aug17.jpgEnvironmental signals drive seed dormancy cycling in the soil to synchronise germination with the optimal time of year; a process essential for species fitness and survival. Previous correlation of transcription profiles in exhumed seeds with annual environmental signals revealed the coordination of dormancy regulating mechanisms with the soil environment. Here, we developed a rapid and robust laboratory dormancy cycling simulation using mutants in known dormancy-related genes. Involvement of the clock in dormancy cycling was clear when mutants in the morning and evening loops of the clock were compared. Dormancy induction was faster when the morning loop was compromised and delayed when the evening loop was compromised.

This whitepaper reports the deliberations of a workshop focused on biotic challenges to plant health held in Washington, D.C. in September 2016. Global food security is threatened by the vulnerability of our agricultural systems to numerous pests, pathogens, weeds, and environmental stresses. These threats are aggravated by climate change, the globalization of agriculture, and an over-reliance on non-sustainable inputs. New analytical and computational technologies are providing unprecedented resolution at a variety of molecular, cellular, organismal, and population scales for crop plants as well as pathogens, pests, beneficial microbes, and weeds. Data-driven, informed decisions based on knowledge of the variation of biotic challenges and of natural and synthetic variation in crop plants will enable deployment of durable interventions throughout the world. These should be integral, dynamic components of agricultural strategies for sustainable agriculture.

Resistance to Sclerotinia sclerotiorum in wild Brassica species and the importance of Sclerotinia subarctica as a Brassica pathogen

plant_pathology_jun17.jpgA Taylor, K Rana, C Handy, JP Clarkson

Brassica crops are of global importance with oilseed rape (Brassica napus) accounting for 13% of edible oil production. All Brassica are susceptible to Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, a generalist fungal pathogen causing disease in over 400 plant species. This is the first study to identify B. cretica as a source of resistance to S. sclerotiorum and to report resistance in other wild Brassica species to a UK isolate, hence providing resources for breeding of resistant cultivars suitable for Europe.

Research on integrated pest and disease management in carrot crops

1153aR.H Collier, D. Wilson, A. Jukes, M.S. Elliott, R. Warmington and J. Clarkson

The paper describes research on integrated pest and disease management in carrot crops, focusing on treatment timings for control of Psila rosae with a relatively new insecticide, Coragen®, the development of a forecast of the timing of the migration of Cavariella aegopodii into carrot crops and the use of biofumigation for control of soilborne plant pathogens such as Sclerotinia sclerotiorum. All three approaches show promise as components of integrated pest and disease management programmes.
