Effect of formulated zimmu (Allium cepa L. × Allium sativum L.) extract in the management of grain mold of sorghum

Suppression of Fusarium wilt disease of banana by Zimmu (Allium cepa L. x Allium sativum L.) leaf extract

“…These are in accordance with the findings of Huang et al (2012) who have studied the effect of Chinese leek (Allium tuberosum) on Fusarium wilt disease incidence and reported 58% reduction of incidence in the banana variety Baxi (AAA) and 79% in the banana variety Guangfen No.1 (ABB) under greenhouse conditions. The foliar application of Zimmu formulation 50 EC at 3 ml L -1 (v/v) concentration at 60, 75 and 90 days after sowing significantly reduced the incidence of grain mold and increased the grain weight and grain hardness (Karthikeyan et al, 2007). The combined application of Trichoderma viride + Pseudomonas fluorescens + Zimmu leaf extract as seed treatment under pot culture studies was superior in reducing the pre and post-emergence chilli damping-off incidence (8.3 and 17.0% respectively) and increasing the plant growth and yield (shoot length and root length of 13.7 and 6.3 cm, 146 g/plant, respectively) of chilli as compared to the control (Muthukumar et al, 2010).…”

“…The evaluation of fungitoxic effects of 66 medicinal plants in vitro on Pythium aphanidermatum, also indicated that only the Zimmu leaf extract showed the highest inhibition of mycelial growth (Muthukumar et al, 2010). Karthikeyan et al (2007) reported that the leaf extract of Zimmu exhibited strong antifungal activity against Aspergillus flavus, Fusarium moniliforme, Curvularia lunata and Alternaria alternata and caused in vitro fungal growth inhibition of 73.3, 71.1, 70.0 and 74.4%, respectively. The crude extract of different Allium species such as Allium fistulosum (Green onion), A. sativum (Garlic) and Allium tuberosum (Chinese leek) inhibited the spore germination of Alternaria brassicola by 100% (Ho et al, 2007).…”

Antifungal Effect and Protective Role of Ursolic Acid and Three Phenolic Derivatives in the Management of Sorghum Grain Mold Under Field Conditions

“…Studies suggesting the usage of combination of captan (0.2%) and aureofungin (200 ppm) followed by mancozeb (0.27) and captan (0.2%), and then thiram (0.2%) and carbendizam (0.5%) for the reduction in grain weathering was found in the literature . Earlier reports on evaluation of field efficacy of some commercial synthetic fungicides like captan, diethane, M‐45 (mancozab), propiconazole, carbendizam were found to be reducing disease incidence to 50% . Recently, the effect of propiconazole in reducing seed‐borne infections at milk stage and grain mold severity at matured stage had been reported by Govardhan and Das .…”
