Efficacy of Fungicides against fusarium Pallidoroseum Causing Fruit Rot of Kachari (cucumis Callosus)

Kachari (Cucumis callosus) is a warm season annual crop which is grown as wild or cultivated crop at large scale with bajra, moth, moong and guar crops in arid and semi-arid regions of Rajasthan. Kachari fruits were found infected with Fusarium pallidoroseum causing severe damage both in quantitatively and qualitatively at Jobner and near by areas during Kharif season 2009. The efficacy of five systemic and non-systemic fungicides was tested in vitro by Poison food technique. Companion (carbendazim 12% + mancozeb 63%) at 100, 300 and 500 ppm was found the most effective in inhibition (100%) of mycelial growth of F. pallidoroseum followed by mancozeb and carbendazim.
