Isothiocyanates (ITCs) are degradation products of glucosinolates in crucifer plants and have repellent effect on insects, pathogens and herbivores. In this study, we report that exogenously applied allyl isothiocyanate (AITC) induced stomatal closure in Arabidopsis via production of reactive oxygen...

Rhizospheric bacteria Bacillus subtilis and Pseudomonas fluorescens are two widely tested biological control agents against root-knot nematodes (RKN) of different crops. However, their performance as bio-control agents varies with their place of origin. Culture filtrates of rhizospheric bacteria con...

Rice (Oryza sativa) stands as a crucial staple food worldwide, especially in Bangladesh, where it ranks as the third-largest producer. However, intensified cultivation has made high-yielding rice varieties susceptible to various biotic stresses, notably sheath blight caused by Rhizoctonia solani, wh...

To control blast disease in the rice field under natural conditions, three antagonistic isolates of rhizospheric P. fluorescens were formulated in talc, kaolinite, PVP, and vegetable oil using an RCBD with three replications. At various phases of the rice plants' growth, all of the products markedly...

Cumin (Cuminum cyminum L.) is an important spice crop worldwide and its production is hampered by the infection of Alternaria blight. Cultivation of cumin in Bangladesh is very limited due to the lack of appropriate germplasm and adequate scientific information regarding the prevalence of Alternaria...

We analyzed the effects of diffusates from six different crops on the egg hatching of Meloidogyne chitwoodi collected from young and senescing tomato plants using a non-linear model. Diffusates only from tomato and carrot significantly delayed the hatching of eggs from young plants, but did not do s...

In Bangladesh most agronomic biomass (straw, husk, dried dung) is burnt for domestic cooking use. Consequently, the soil is continuously stripped of mineral nutrients and carbon (C) substrate. Here we investigate if recycling of household ash (ash) as fertilizer can sustainably improve soil fertilit...

Fluorescent Pseudomonads (Pseudomonas fluorescens and P. putida) were formulated in talc, bentonite, palm oil and coconut oil for the management of blast disease of rice. The formulated products showed promising shelf-value. The formulated products were evaluated by root dipping of rice seedlings an...

Culture filtrates collected from Trichoderma harzianum were assayed to control seed-borne fungi of selected vegetables viz. bottle gourd, wax gourd, sweet gourd, snake gourd and okra. Three fungal genera comprising of four species viz. Aspergillus niger, Aspergillus flavus, Penicillium spp. and Fusa...

Induced resistance (IR) is a unique physiological state characterized by reduced plant susceptibility to (a)biotic stress. Our previous studies showed that exogenous foliar application of dehydroascorbate (DHA), the oxidized form of ascorbic acid, induces systemic resistance against root-knot nemato...

Rice production is severely affected by sheath blight disease in Bangladesh which is caused by a fungus Rhizoctonia solani that is still merely managed by synthetic chemical fungicides. In this study, different isolates of Pseudomonas fluorescens and Bacillus subtilis were evaluated to assess their ...

A field experiment was conducted to investigate the efficacy of Trichocompost utilizing Trichoderma as biological agent. Three doses of Trichocompost viz. 500g/m<sup>2</sup>, 750g/m<sup>2</sup>, 1000g/m<sup>2</sup> were applied including untreated control treatment. All the yield parameters were sig...

Abstract Isolation and identification of native fluorescent Pseudomonads from the rice rhizosphere were evaluated for their growth suppressing ability against blast disease of rice causing pathogen (Magnaporthe oryzae). Twenty strains of fluorescent Pseudomonads were isolated and identified initiall...
