This study was carried out to elucidate suppressive effect of loess-sulfur complex and neem oil on the development of leaf mold and fungus gnat in no-pesticide tomato farming system. Since tomato leaf mold occurred 15%, neem oil, loess-sulfur mixture and boscalid(47%, water soluble chemicals) 2,000 times, 1,000 times and 2000 times diluted was treated three times, respectively. When disease incidence of tomato leaf mold was investigated 20 days after final treatment, it was recorded 17% in neem oil treatment(control efficacy 40%) and 12.3% in loess-sulfur mixture treatment(control efficacy 59%). Among three control agents used, Boscalid(47%, water soluble chemicals) showed the best control effect against tomato leaf mold. When neem oil was diluted 250 times, 330 times and 500 times and treated in coir bag infected with fungus gnat, its control values was 69, 59, and 55%, respectively. There was no significant difference among three treatments. As a result, 500-fold diluted neem oil treatment is considered a good measure to control fungus gnat in the field condition.

Cherry tomato ‘TY Candy’ F₁ Hybrid was bred in Tomato Life Science and Research Institute from 2008 to 2014, which has indeterminate plant type, oblong fruit shape, average fruit weight 17 ~ 22 g and sugar content brix 8 ~ 9. Female line was selected and fixed with vigorous plant, firm fruit texture, Fusarium and Cladosporium resistance. Male line was selected and fixed with medium internode, deep leaf color, high brix, Yellow leaf curl virus and Nematode resistance. F₁ combination was made and pollinated in 2011 year, hybrid selection and sample seed production were progressed in 2012 year, farmers’ field trial was conducted at major tomato cultivation area and resulted good performance in 2013 ~ 2014. The distinctive characteristics of ‘TY Candy’ are higher yield, fruit quality and TYLCV, Nematode, Cladosporium etc. multi-disease resistance compared to existed varieties.
