Early blight is the most devastating disease of tomato it is caused by pathogens i.e. Alternaria solani. In tropical and subtropical countries it creates hazardous effect. It is also a common problem in United Kingdom, Australia, India, Nepal and United States. It is one of the most common foliar diseases of tomatoes. The disease can occur over a wide range of climatic conditions, but is most prominent in areas with heavy dew, rainfall and high relative humidity. Every year sever disease appears in north India.

The field experiment on screening of tomato lines for GBNV infection was carried out Horticultural College and Research Institute, Tamil Nadu Agricultural University and Coimbatore. Totally 25 hybrids/varieties were screened in Rabi season during 2015. None of the varieties/hybrids screened were resistant or immune to GBNV during Rabi season. However, average disease incidence ranged from 7.55 to 25.25 percent indicating moderately resistant to highly susceptible.

Fusarium oxysporum f. Sp lycopersici is the causal organism that causes wilt disease in tomato all over the world. The antifungal activity of aqueous extract of neem leaf (5%), ginger bulb (5%), Lantana camara (5%), Trichoderma harzianum (5%), carbendazim (0.01%) and combination of carbendazim+T. harzianum (0.01+5%) was investigated against Fusarium oxysporum f. sp lycopersici in vitro.The least growth of pathogen was recorded in Carbendazim (treated control) (94.00) followed by Neem leaf (35.20) followed by Lantana camara (31.11), ginger bulb (26.

The Screening of tomato cultivars (hybrids/ varieties) for whiteflies in field condition was carried out during 2012-13. All the experimental studies were conducted at Main Agriculture Research Station Raichur Karnataka. The results revealed that, 15 Days after transplanting Vybhav recorded least number of adult (1.00/ three leaves) followed by Arka Samrat, PTR 4 was significantly preferred variety with highest (4.50) number of adult whitefly population.

Field screening of F3 generation interspecific tomato hybrids derived lines for resistance to Peanut bud necrosis virus (PBNV) was carried out in the Department of Horticulture, Agricultural College and Research Institute, Madurai, Tamil Nadu Agricultural University, Tamil Nadu, during 2019-2020. PBNV is the most destructive and economically important plant virus in tomato which causes yield loss up to 80 to 100 per cent. The present study was formulated to develop PBNV resistant lines in tomato suitable for commercial cultivation. Totally 35 lines from four interspecific crosses Viz.

Tomato leaf curl disease caused by tomato leaf curl virus (ToLCV) is a major limiting factor in tomato cultivation in Jammu region of Jammu and Kashmir. Screening of different germplasm collected from different sources against the disease showed that out of fifteen germplasm, Mahaveer and Avinash-2 were found resistant, Samrudhi F1 and Namdhari 82535 were found moderately resistant while eleven germplasm viz. Heem Sohna, Sonali, Rupali, NS 816, NS 812, Pusa Ruby, Indus 1030, Arti, DVRT-2, Hybrid no. 15 and local showed susceptible reaction.

A study was conducted to evaluate the reaction of tomato genotypes to root knot nematode (Meloidogyne incognita race - 3) and the nematode reproduction were studied in the nematode infested pot culture experiment. Forty tomato genotypes were subjected for screening. At 65 days after nematode inoculation, whole plants were uprooted, washed and ranked for root galling and egg mass indices on a 1 to 5 scales. The plant growth responses viz.

A field study was conducted to screen out six important tomato genotypes for resistance/ tolerance against important sucking pests and their natural enemies under West Bengal conditions. Aphid (Aphis gossypii Glover) and whitefly (Bemisia tabaci Genn.) were first appeared on the crop in third week of January and second week of February respectively. The peak populations of both the pest were reached in the third to fourth week of February.

Tomato leaf mold is a common disease in tomato cultivation. This disease is caused by Cladosporium fulvum, which has many physiological races and differentiates rapidly. Cf genes confer resistance to C. fulvum, and the C. fulvum-tomato pathosystem is a model for the study of gene-for-gene interactions.
