“…Trichoderma based BAU bio-fungicide also showed the positive effect on plant growth parameters, however; the effect was less in compare with PGP hormone and Carbendazim treatment. Several studies also reported that plant height and weight increased with BAU bio-fungicide in different vegetables [22] and in this study, BAU bio-fungicide (seed treatment followed by spray) averagely increased plant height from 59.75 to 67.84 cm in both varieties. In lettuce, Yedicula cultivar with the application of Tricoderma in per peat number of leaf calculated 3.8 to 4.3, hypocotyls length measured 5 to 8.5 cm, and seedling fresh weight found 3.8 to 4.3 gm at 15 gm/m 2 dosages and root weight resulted 0.18 to 0.28 gm at 10gm/m 2 dosages [23].…”

Trichoderma based BAU-biofungicide, chemical Carbendazim and a synthetic plant growth promoting (PGP) hormone have been used to study their effect on Cercospora leaf spot of Indian spinach. Number of leaf, number of infected leaf, disease incidence, disease severity, area under disease progress curve (AUDPC), plant height and plant weight were measured and significant variations was found against different treatment combinations. Among the treatment combinations, seed treating with Carbendazim followed by foliar spray with Carbendazim, seed coating with BAU bio-fungicide followed by foliar spray with Carbendazim, only foliar spray with Carbendazim and only spray of PGP hormone significantly reduced disease incidence and severity with increasing of plant height and weight. Interestingly, foliar application of PGP hormone reduces disease incidence and severity by 58.38% and 63.8% in both the variety of Indian spinach, respectively over control, whereas; in both the variety disease incidence and severity is reduced by seed treatment with Carbendazim followed by foliar spray with Carbendazim 69.72% & 77.63%; seed treatment with BAU bio-fungicide followed by foliar spray with Carbendazim 63.73% & 69.49%; foliar spray with Carbendazim 55.68% & 58.19%, respectively. Foliar application of PGP hormone along with the reducing of disease incidence and severity, also increases the leaf number by 68.62%, plant height by 54.64% and plant weight by 65.69% over control. AUDPC showed that, local variety of Indian spinach is more susceptible to Cercospora leaf spot than BARI spinach 1.

“…Other management practices in the developing countries include seed treatment with non-conventional chemicals (Maiti et al 2005), cultural practices by adjusting sowing times (Naidu and Vasanthi 1995), and through use of biological control agents (Kishore and Pande 2005) and botanicals (Hossain and Hossain 2013). Multiple applications of chemical fungicides offer quick and effective remedy for these diseases.…”

Late leaf spot (LLS) (Phaeoisariopsis personata) and rust (Puccinia arachidis) are major foliar diseases of peanut causing significant losses worldwide. Identification and infusion of resistance into peanut cultivars is important in the management of these diseases. The present study therefore aimed at screening the peanut mini core collection to identify potential sources of resistance to these diseases. Two separate field experiments were conducted for screening LLS and rust under artificial epiphytotic conditions during rainy seasons of 2012 and 2013 at ICRISAT, Patancheru, India. The trials were laid in a randomized complete block design on beds with three replications. Data on LLS and rust disease severities were collected using 1 to 9 scales at 75, 90 and 105 days after sowing (DAS), and pod yields were recorded at harvest. Results indicate significant variations among accessions for LLS and rust resistance. Mean of 2 years study revealed that 53 accessions were moderately resistant (MR), 86 accessions were susceptible (S) and 45 accessions were highly susceptible (HS) to LLS. For rust disease, 10 accessions were resistant (R), 115 accessions were with 'MR' reaction and 59 accessions with susceptible (S) reaction. Six superior accessions in terms of combined disease resistance and yield (ICGs 4389, 6993, 11426, 4746, 6022, 11088) were selected and the disease progress curves, for each, were generated. Highest yields were recorded with ICG 11426 in LLS and rust plots. Overall, our results indicate that these six accessions can be potential sources of LLS and rust resistance.
