“…However, some genotypes did not show high disease incidence but lost significant dry weight. Thus some genotypes lost energy in overcoming disease stress, even when no disease symptoms were apparent; a finding similar to Alwathnani and Perveen, (2012). The Fusarium pathogen interrupts enzyme activity, especially those related to pathogenicity including cellulase, lipase, protease, pectinase and many others (de Guadalupe Moctezuma- Zárate et al, 2013).…”

Tomato is an important vegetable crop worldwide and Fusarium wilt is a significant disease of tomato in many countries. One hundred and fifty three diverse tomato genotypes collected from local and exotic sources were screened for resistance to F. solani in the greenhouse. Significant variation in genotype response to inoculation was observed. The organic metabolite profiles of resistant and susceptible genotypes were assessed to determine the basis of resistance. Significant genetic variation was observed for ABA, malic acid, citric acid, fructose, glucose, sucrose, L-proline and myo-inositol. The disease treatment produced significant changes in fructose, glucose, proline and sucrose and significant genotype-by-treatment interaction was observed for ABA, citric acid, fructose, glucose, malic acid and sucrose, indicating that genetic improvement of these traits is feasible. Disease incidence was strongly associated with citric acid (R 2 = 0.84), sucrose (R 2 = 0.72) and L-proline (R 2 = 0.76). Principal component analysis confirmed that citric acid and L-proline were important in determining plant disease response. Genetic variation for Fusarium wilt resistance can be used to develop new tomato cultivars with improved disease resistance.

Five fungal antagonists viz., Aspergillus flavus, Aspergillus luchuensis, Penicilliun citrinum P. chrysogenum and Trichoderma viride were isolated from soil of guava orchards near the bank of river Ganga, Kanpur, following serial dilution plate technique; evaluated against guava wilt pathogen i.e. Fusarium solani at 10%, 25%, 50%, 75% and 100% concentration following "Poisoned food technique". The antagonists were effective in controlling the growth of test pathogen at different levels. Among the antagonists tested, Aspergillus luchuensis was effective by 89.68% (3 rd day), 92.32% (5 th day) and 93.85% on (7 th day) after inoculation at 100% concentration followed by Aspergillus flavus and Penicillium citrinum by 78.52% and 77.96% (3 rd day), 84.10% and 81.86% (5 th day), 87.29% and 82.59% on (7 th day) respectively. However, P. chrysogenum and Trichoderma viride gave almost similar results and inhibited the mycelial growth of pathogen by 79.50% and 79.95% on 7 th day after inoculation at 100% concentration respectively.

“…T 5 (seed treatment with T. harzianum+ foliar spray with carbendazim) and T 6 (seed treatment with T. harzianum+ foliar spray with neem leaves extract) treatments were showing 7.9 g and 6.00 g in dry shoot weight, respectively. Alwathnani and Kahkashan (2012) reported that seed treatment with bioagents (Aspergillus niger, Penicillium citrinum, Penicillium sp. and Trichoderma harzianum) significantly increased plant height , fresh weight and dry weight of plant.…”

Integration of different methods for sustainable management of Fusarium wilt of tomato revealed that all the treatments were able to significantly reduce the disease severity over control. Among the treatments, the minimum disease severity was recorded in the T 3 treatment where treatment was given as seed treatment with T. harzianum + soil application of neem cake powder + foliar spray of carbendazim, representing the value 4.82, 8.23, 12.37 and 16.37 per cent against 10.75, 14.84, 20.00 and 25.75 per cent in case of control at 30, 45, 60 and 75 days age of plant, respectively. Integrated approach has also been able to increase shoot length as 27.00, 42.15, 54.98, and 65.07 cm at 30, 45, 60 and 75 days age of plant, respectively whereas in case of control it was 18.60, 25.70, 34.63 and 44.29. Similarly, fresh and dry shoot and root weight have also been found increased in case of integrated approaches. Biochemical analysis of the treated plants revealed that highest soluble protein and total phenol content is observed in T3 treatment (Seed treatment with T. harzianum + soil treatment with neem cake powder and foliar spray with carbendazim), showing 37.85, 36.78 and 35.76 mg/gm of fresh leave of protein and 2.40, 2.14 and 2.04 mg/gm of fresh leave of phenol at 30, 45 and 60 days age of plant. As per yield is concerned, it has found that the maximum yield was obtained per plant from the treatment given as seed treatment with T. harzianum + soil treatment with neem cake powder + foliar spray with carbendazim, showing the value of 500 g per plant which was followed by the treatment given as seed treatment with T. harzianum + soil treatment with neem cake powder + foliar spray with neem leaf extract showing 470 g per plant.
