Two full spring season tomato crops (Lycopersicon esculentum Mill. “Trust”) were grown in an open rockwool system with standard rockwool feeding formulae (O-R; conventional method), and in closed rockwool systems with standard rockwool (C-R) or Nutrient Film Technique (C-NFT) feeding formulae (modified in 1997) in 1996 and 1997 to examine the feasibility of a fully closed rockwool production system with appropriate feeding formulae. The closed rockwool system with optimized feeding formulae achieved high marketable yield, similar to that of the open rockwool system. There were no differences in early plant growth, plant biomass or biomass partitioning, and in total fruit yield, size and grades except for the closed rockwool system with the standard rockwool feeding formulae (C-R), which had lower yield than C-NFT in the last month of harvest in 1996. The photosynthesis of old foliage was higher and the root systems at the end of the experiments were rated healthier in plants grown in the closed (C-R and C-NFT) systems than in plants grown in the open (O-R) system. Over 30% of water and fertilizer was saved with the closed systems in comparison to the conventional open system. These results demonstrated that closed rockwool systems with optimized nutrient feedings are economically and environmentally sound alternative methods for greenhouse tomato production in Ontario.

AgriPhage applied as a preventative foliar spray significantly reduced severity of bacterial canker of greenhouse tomato in two of three years. Area under the disease progress curves (AUDPC) indicated that AgriPhage slowed the progression of bacterial canker symptom development by 50% and 59% in 2006 and 2007, respectively. Plant mortality was significantly reduced by 76% in 2006 as compared to the inoculated control. AgriPhage-treated plants produced significantly greater total yield in 2006 only. Copper and Kasumin sprays also significantly reduced severity (AUDPC) of bacterial canker in 2007 as compared to the inoculated control. However, none of these treatments reduced symptom development or increased yield in 2008. Accepted for publication 9 April 2009. Published 12 May 2009.
