Abstract
A study was made to evaluate the effectiveness of seed treatment (4 g/kg seed) and soil application (4 g/kg soil) of Trichoderma atroviride, T. auroviride, T. hamatum, T. harzianum, T. koningii, T. longibrachiatum, T. virens, and T. viride for managing white mould caused by Sclerotinia sclerotiorum (2 g/kg soil) in pea (Pisum sativum) under pot condition. The pea cv. Vasundhara was found highly susceptible to the white mould fungus, exhibiting irregular water-soaked lesions on stems, branches and leaves. Application of Trichoderma spp. reduced the severity of mould by 27–29% and significantly enhanced the plant growth (19–22%) and yield of pea (11–16%) over control. The treatments with T. harzianum provided maximum enhancement in the plant growth (14–32%) and yield (9–13%). The root nodulation was promoted by 14–21% (T. harzianum) and 11–17% (T. virens) over control. Overall, seed treatment with Trichoderma spp. on seeds provided relatively greater control of Sclerotinia mould of pea and subsequent enhancement in the yield in comparison to soil application.
