| ABSTRACT: A pot experiment was carried out for the biological control of charcoal rot on mung bean (Vigna radiata), caused by Macrophomina phaseolina. Pot soil was made sick with an inoculum of M. phaseolina. Dried powdered leaves of Sisymbrium irio, a weed from the Brassicaceae family, were mixed in soil at 1, 2 and 3% (w/w) with and without the application of Trichoderma harzianm, a fungal biological control agent. The highest grain yield (3.62 g pot-1) was recorded in a combined application of T. harzianum and 1% S. irio leaf amendment, which was 62% and 805% higher than negative and positive control treatments, respectively. The application of S. irio leaf amendment and T. harzianum generally enhanced leaf protein, sugar and chlorophyll contents, and... |

| ABSTRACT: A pot experiment was carried out to check the effect of Coronopus didymus (L.) Sm. dry biomass application (1%, 2% and 3% w/w) and two species of Trichoderma (T. viride and T. aureoviride) on growth and physiology of mungbean [Vigna radiata (L.) WIlczek] under biotic stress of Macrophomina phaseolina (Tassi) Goid. Inoculation of M. phaseolina (positive control) reduced plant survival, shoot and root length as well as plant dry biomass by 22%, 52%, 61% and 64%, respectively, over the negative control (without any amendment). There was 100% plant survival in treatments with T. aureoviride alone or in combination with 1% and 2% C. didymus biomass. Likewise, T. viride in combination with 2% biomass also showed 100% plant survival. Application of 3%... |

| ABSTRACT: Antifungal potential of aerial parts of an allelopathic grass Cenchrus pennisetiformis (Hochst. & Steud.) Wipff. was evaluated against Fusarium oxysporum f. sp. lycopersici Snyder & Hansen, a fungal pathogen causing wilt disease in tomato (Solanum lycopersicum L.). Different concentrations (1% to 6%) of methanolic leaf, stem and inflorescence extract of the grass significantly reduced fungal biomass by 40-88%, 13-89%, and 26-76%, respectively. Methanolic shoot (leaf + stem) extract was fractionated using four organic solvents viz. n-hexane, chloroform, ethyl acetate and n-butanol. All the sub-fractions of methanolic shoot extract showed remarkable antifungal potential to variable extents. Different concentrations (1.56-200 mg mL-1) of... |

| ABSTRACT Sclerotium rolfsii is a soil-borne fungal plant pathogen that causes diseases in more than 500 plant species. Chemical fungicides used to control this disease cause environmental pollution, therefore, plant derived compounds can be used as alternative to synthetic fungicides to reduce environmental pollution. Chenopodium album is a weed of family Chenopodiaceae that is used as food and also has medicinal importance. In the present study, antifungal activity of methanolic root extract of C. album was evaluated against S. rolfsii using six concentrations viz. 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 g 100 mL-1 amended in malt extract as growth medium. All the root extract concentrations significantly reduced fungal biomass by 15-58% over control. Gas... |

| ABSTRACT Biopower is a commercial rice biofertilizer comprised of various associative nitrogen fixers. In this present study, a field trial was carried out to assess the effects of Biopower application on the growth of some rice weeds and yield of rice (Oryza sativa). Four common rice weeds namely Cyperus rotundus, Echinochloa colonum, Marsilea minuta, Paspalum paspaloides, and mixed weeds were sown in 1:1 weed crop ratio in soil amended with i) ½ dose of N (nitrogen) + recommended doses of PK (phosphorus, potassium) fertilizers, ii) recommended doses of NPK fertilizers, and iii) farmyard manure (FYM) + ¼NPK fertilizers, with and without Biopower application. Biopower application variably reduced weed biomass in different soil amendment systems. The effect... |

| ABSTRACT The present study was conducted to assess antifungal potential of the allelopathic grass Cenchrus pennisetiformis Hochst. & Steud. against the fungal plant pathogen Fusarium oxysporum f. sp. lycopersici (cause of tomato wilt disease) under chromium stress. Laboratory experiments were performed in 10 mL volume glass test tubes each containing 1.0 mL of malt extract broth with seven concentrations (0, 50, 100, 150, 200, 250, 300 and 350 ppm) of each of Cr(III) and Cr(VI), and two concentrations (5% and 6%) of methanolic leaf, stem or root extract of C. pennisetiformis. A metal + weed extract amended medium was inoculated with the pathogen and incubated for 7 days at 25 C. Different concentrations of Cr(III) and Cr(VI) proved equally inhibitory... |

| ABSTRACT Macrophomina phaseolina, a soil-borne plant pathogen, has the ability to cause diseases in about 500 plant species. Unfortunately, so far no registered fungicide is available against this fungal pathogen. In the present study, different extracts of Sisymbrium irio, a weed of family Brassicaceae, were tested for evaluation of their antifungal activity against M. phaseolina. In screening bioassays, antifungal activity of methanolic extracts of 1% to 6% concentrations of different parts (leaf, stem, root and fruit) of the weed was assessed against the fungal pathogen. Methanolic leaf and root extracts significantly reduced fungal biomass up to 59% and 69% over control, respectively. Methanolic leaf and root extracts were further partitioned using... |

| ABSTRACT Leaves, stems, roots and inflorescence of the asteraceous weed Circium arvense were extracted in methanol for two weeks. Methanol was evaporated in a rotary evaporator. Different concentrations (1, 2, 3, 4 and 5%) of methanolic extracts were prepared, and their antifungal activities were studied against Macrophomina phaseolina, using malt extract broth as growth medium. In general, extracts of all plant parts showed antifungal activities to variable extents. The highest antifungal activity occurred due to methanolic extract of leaves, followed by stem and root extracts, resulting in 10-74%, 6-57% and 11-39% reduction in fungal biomass over control, respectively. Inflorescence extract showed the least antifungal activity, resulting in 2-30%... |
