The effects of broadleaf tobacco, tomato, and black nightshade on juvenile hatch and reproduction of Globodera tabacum tabacum were determined in laboratory and greenhouse experiments. Root exudates from nightshade stimulated greater egg hatch than those from either 'Rutgers' tomato or '86-4' tobacco. Hatch was greater at higher proportions of root exudates for all three plant species. Root exu...

Studies were done to evaluate specific strains of plant growth promoting rhizobacteria (PGPR) for induced resistance against cucumber mosaic cucumovirus (CMV) in tomato. In greenhouse experiments where plants were challenged by mechanical inoculation of CMV, the percentage of symptomatic plants in the most effective PGPR treatments ranged from 32 to 58%, compared with 88 to 98% in the nonbacter...

The South American tomato pinworm (Tuta absoluta) has recently invaded Europe and is rapidly spreading in the Afro-Eurasian continent where it is becoming a major pest on tomato crops. Laboratory tests were undertaken to evaluate the potential of 29 European strains of Trichogramma parasitoids to control T. absoluta. In addition to the host itself, the host plant (tomato) was used during the la...

Agriculture is extremely vulnerable to climate change. Greenhouse farming recognized as a promising measure against Nevertheless, greenhouse frequently encounters environmental adversity, especially greenhouses built protect typhoons. Short-term microclimate prediction challenging because meteorological variables are strongly interconnected and change rapidly. Therefore, this study proposes wat...

Tomato (Lycopersicon esculentum Mill.) is the one of major greenhouse vegetable crops throughout the world. In terms of nutritional value, tomato is an excellent source of vitamin A and C, carotenoids, α-tocopherol, as well as phenolic compounds as antioxidants [1]. However, the quantity or quality levels of such phytochemicals vary considerably depending on genotype, and/or environmental condi...

Bacterial wilt of tomatoes caused by Ralstonia solanacearum is a devastating disease that limits the production of tomato in Korea. The best way to control this disease is using genetically resistant tomato plant. The resistance degree to R. solanacearum was evaluated for 285 tomato accessions conserved in the National Agrobiodiversity Center of Rural Development Administration. These accession...

Greenhouse detection and mapping via remote sensing is a complex task, which has already been addressed in numerous studies. In this research, the innovative goal relies on the identification of greenhouse horticultural crops that were growing under plastic coverings on 30 September 2013. To this end, object-based image analysis (OBIA) and a decision tree classifier (DT) were applied to a set c...

Fusarium species are causal agents of fungal diseases occurring frequently in numerous agriculturally important plants, including potato, garlic and are one of the common pathogens of tomato, causing root rot in the west part of Iran. Therefore, the objectives of this study were to isolate and identify disease-causing Fusarium species from infected tomatoes based on the morphological and molecu...

KOSTOV, K., R. BATCHVAROVA and S. SLAVOV, 2007. Application of chemical mutagenesis to increase the resistance of tomato to Orobanche ramosa L. Bulg. J. Agric. Sci., 13: 505-513 In this study chemical mutagenesis of tomato seeds with Ethylmethanesulfonate was used to obtain lines with increased resistance to Orobanche ramosa L. The M2 progeny of the mutant tomato plants was screened for the res...
