Rice stem rot disease in paddy cultivation leads to reduction of yield. Management this is difficult as it soil borne. In the present study, field trials were conducted during Rabi 2016-17 and early Kharif 2017-18 assess effectiveness twelve fungicides four rhizosphere bacterial antagonistic isolates (RRB-1 RRB-4) against rice disease. Disease incidence was recorded from date initial i.e., once...

While fungicides may be a major mechanism for control of avocado root rot, integrated management requires several other non-fungicidal approaches which are used together to maximize root rot control. Non-fungicidal methods of control include planting clean avocado nursery stock, selecting low hazard sites, planting on mounds in more hazardous sites, preventing the introduction of P. cinnamomi, ...

the common root rot of wheat caused by bipolaris sorokiniana is considered as an important disease of world wide distribution including iran. biological control of b. sorokiniana can be an effective method for control of this disease. for this purpose, the biocontrol potential of mycorrhiza glomus fasciculatum, pseudomonas fluorescens sh4 and a mixture of the two was evaluated for the common ro...

Maize is susceptible to a number of diseases that can infect all plant organs and serve as constraint on cereal production. The reduction in production caused by disease estimated at an average 9.4%. Corn root rot contributes greatly the grain quality. main objective this work was review research maize determine susceptibility genotypes quantify inheritance resistance maize. methodology used co...

this experiment was conducted for determining the effect of irrigation termination before harvesting and late application of nitrogen on sugar beet yield, quality and root rot during 1993-95 at safiabad agricultural research center. different irrigation termination and late nitrogen application treatments had a significant effect on root yield. terminating irrigation 1 and 3 weeks before harves...

metallic silver nanoparticles have been reduced from silver nitrate by employing the extracellular enzymatic machinery of edible white button mushroom (agaricus bisporus). the physical properties of these particles, size and shapes have been determined using techniques like tem, ftir and xrd and were reported in our earlier report. but, what stands of paramount importance in the present context...

Phytophthora is a genus of plant pathogens, many species of which live in water or soil. The name means “plant destroyer” in Greek. Phytophthora species are common pathogens in agricultural systems, especially in those where the crop is irrigated with surface or recycled water. In cranberry culture, the most troublesome species is P. cinnamomi, the cinnamon fungus. This pathogen causes a very c...

Spot blotch is caused by Helminthosporium sativum or H. sorokinianum = Drechslera sorokiniana (Bipolaris sorokiniana). The disease is widespread in Illinois and is believed to lower potential barley yields by 1 to 3 percent; also, the bushel weight. The causal fungus affects all parts of the plant and produces a variety of symptoms, from a seedling blight and root rot to “Black point” of the ke...
