Experiments were conducted to identify blast-resistant fragrant genotypes for the development of a durable blast-resistant rice variety during years 2012-2013. The results indicate that out of 140 test materials including 114 fragrant germplasms, 25 differential varieties (DVs) harbouring 23 blast-r...

An investigation was made to manage strawberry black root rot caused by Rhizoctonia solani (R. solani) through the integration of Trichoderma harzianum (T. harzianum) isolate STA7, mustard oil cake and Provax 200. A series of preliminary experiments were conducted to select a virulent isolate of R. ...

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...

Rice blast and bacterial blight diseases are the global threat for rice production. To develop blast and bacterial blight resistant lines, two blast resistance genes (Pi9 and Pb1) and three bacterial blight resistance genes (xa5, xa13 and Xa21) were pyramided in the background of premium quality ric...

Efficacy of various concentrations of four plant extracts prepared from garlic, Neem leaf, ginger and onion bulb on reduction of seed-borne fungi was evaluated. Among the treatments, garlic extract preparations (1:0, 1:1 and 1:2) and fungicide Rovral (0.25% of seed weight) had shown to enhance seed ...

Genetic variation in blast resistance was clarified in 334 Bangladesh rice accessions from 4 major ecotypes (Aus, Aman, Boro and Jhum). Cluster analysis of polymorphism data of 74 SSR markers separated these accessions into cluster I (corresponding to the Japonica Group) and cluster II (correspondin...

Bacterial Blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo), a destructive disease of rice. Altogether, 96 isolates of Xoo were collected from 19 rice growing districts of Bangladesh in irrigated and rainfed seasons during 2014 to assess pathotypic variation. Pathotypic analyses on a set of ...
