Tomato is one of the most remunerable and widely grown vegetables in world. The objective this study was to evaluate tomato varieties for nematode Ralstonia diseases resistance productivity.

Intercropping could alleviate soil-borne diseases, however, few studies focused on the immunity of the host plant induced by the interspecific interactions. To test whether or not intercropping could enhance the disease resistance of host plant, we investigated the effect of companion cropping with potato onion on tomato Verticillium wilt caused by Verticillium dahliae (V. dahliae). To investig...

Principally, plants grown in soilless culture may be attacked by the same pests and diseases as cultivated traditionally in soil. The most destructive phytopathogens are fungi, such as Phythium, Phytophthora and Fusarium, followed by viruses, bacteria and nematodes. We investigated effect of carbon nanotube filters on disease management of soilless culture. Tomato seedlings transplant in plasti...

It has been proposed that cloned plant disease resistance genes could be transferred from resistant to susceptible plant species to control important crop plant diseases. The recently cloned N gene of tobacco confers resistance to the viral pathogen, tobacco mosaic virus. We generated transgenic tomato plants bearing the N gene and demonstrate that N confers a hypersensitive response and effect...

In this work we applied simple computer graphics techniques and artificial neural networks technology to identify the tomatoes that had foliage diseases. We propose the use of low cost computational apparatus to support early detection of diseases and pests in Brazilian tomato crops. A description of methods and results are presented in this work. Our proposal consorts field experiments with in...

in 2010- 2012 surveys, witches'- boom disease of tomato was observed in borazjan area (bushehr province, iran). agent of the disease was transmitted from tomato to tomato and eggplant by grafting and to madagascar periwinkle via dodder inoculation, inducing phytoplasma-type symptoms in inoculated plants. presence of phytoplasma in naturally affected tomatoes and all symptomatic graft and dodder...

The consumption of tomato products has been associated with a decreased risk for chronic inflammatory diseases. In this study, the anti-inflammatory potential of tomato ketchup was evaluated by studying the effect of tomato ketchup extracts and bioactives from tomato ketchup on human monocytes and vascular endothelial cells (HUVEC). HUVEC were pre-treated for 1 h with either individual bioactiv...

phytoplasmal big bud is one of the important diseases of tomato (lycopersicon esculentum) in the world. the disease has been reported from iranian provinces of bushehr, isfahan, fars, khorasane razavi and ardabil. during a summer surrvey in 2010, symptoms of big bud disease was observed in tomato fields of dorood area in lorestan province. characteristic symptoms of the disease were small thick...
