1 Practices to Prevent Pathogen Transmission During Tomato Grafting Operations Sally A. Miller, Kai-Shu Ling, Fulya Baysal-Gurel, Rugong Li, Donna Henderson 8 November 2012 Grafting Mini-Symposium Orlando
2 Greenhouse Tomato Production Flow Seed Crop Work Propagation Germination Seedling production Grafting Topping Transplanting Training Dropping Staking De-leafing Pruning Harvest
3 Grafting Tomatoes and Pathogen Transmission Rootstock and scion = double chance of pathogen introduction Contaminated hands, tools, clothing spread pathogens during grafting and topping Ebb and flow irrigation may spread pathogens
4 Mechanically Transmitted Pathogens High risk to crop health May also be seedborne Bacterial canker Most risky pathogens Clavibacter michiganensis subsp. michiganensis Pepino mosaic virus (PepMV) Viroids Botrytis PepMV Photo Kai-Shu Ling, USDA-ARS Botrytis Photo Fulya Baysal-Gurel, Viroid Photo Kai-Shu Ling, USDA-ARS
5 A Molecular Tool to Study the Biology of Cmm Transmission in Tomato Marked strains to visualize bacteria Cannot interfere with virulence Must be stable Should be active in live cells only Lux genes bioluminescence ATP-dependent actively metabolizing cells emit light Amount of photons emitted correlated with number of living cells Xu et al Appl. Env. Microbiol 76:
6 Cmm Quickly Colonizes Seedlings 1 day 2 day 3 day 4 day 5 day Real-time in vivo images of a tomato seed inoculated with BL Cmm6, taken 1-5 days after seed placed on water agar Rainbow scale represents approximate photon counts (p/s/cm2)
7 Post-Grafting Environment High relative humidity (80-90%), low light (50 % of normal maximum) for the first week Medium relative humidity (50-60%), moderate light (70% of normal maximum) for the second week Conditions typical for tomato seedling acclimation until transplanting
8 Effect of Relative Humidity on Internal Colonization by Cmm 5 DPI 10 DPI 83% RH 45% RH 83% RH 45% RH Three-week old seedlings clip-inoculated with bioluminescent Cmm. Images taken every 5 days post inoculation (DPI). 15 DPI 20 DPI Xu et al Phytopathology 102:
9 Effect of Relative Humidity on Root Colonization by Cmm Control 83% RH 45% RH 20 DPI
10 Can Moisture Management Help Control Bacterial Canker? High moisture during propagation is designed to Enhance germination Encourage seedling growth Heal graft unions quickly Research is needed to Reconcile optimal horticultural conditions with need to minimize bacterial growth and colonization Determine effects of this environment on virus, viroid and fungal transmission
11 Managing by Sanitation An established cultural practice Reduce or eliminate inoculum How effective are common disinfectants in killing mechanically transmitted pathogens during grafting and crop work?
12 Requirements for Sanitizers Very short contact time Broadly effective against viruses, viroids, bacteria and fungi Not dangerous to workers Not corrosive to infrastructure or phytotoxic to plants Economical
