Ralstonia solanacearum species complex (RSSC) consists of three species, including R. solanacearum, pseudosolanacearum, and syzygii. The K60-type strain was isolated from a wilted 'Marglobe' tomato in Raleigh, North Carolina (NC) 1953 (Kelman 1954). It is classified as phylotype IIA, sequevar 7 (Prior Fegan 2005). In July 2023, during field visit Eastern NC, patches >50 eggplant (Solanum melongena cv. Pingtung Oriental) lycopersicum Saybrook) plants showing wilt symptoms were observed 1...
Rice blast caused by Pyricularia grisea Sacc. is the important disease of rice and different fungicides against this were evaluated in summer 2014 at Karma Research Development Center, Jyotinagar, Chitwan, Nepal. A susceptible cultivar ‘Mansuli’ was planted randomized complete block design viz. Tricyclazole 22% + Hexaconazole 3% SC (0.2%), Streptomycin 5% Thiophanate Methyl 50% WP (0.15%), Prochloraz 25% EC (0.3%), Kasugamycin 2% 4% Zineb 68 % (0.2%) Udaan (Hexaconazole SC) sprayed thrice...
Wheat ( Triticum aestivum L.) is one of the major staples in Nepal providing bulk food calories and at least 30% Fe Zn intake 20% dietary energy protein consumption; thus, it essential to improve its nutritional quality. To select high-yielding genotypes with elevated grain zinc iron concentration, sixth, seventh, eighth, ninth HarvestPlus Yield Trials (HPYTs) were conducted across diverse locations for four consecutive years: 2015–16, 2016–17, 2017–18, 2018–19, using 47 biofortified 3...
Fusarium wilt of banana (FWB), caused by oxysporum f. sp. cubense (Foc), is the most important constraint industry globally. In Nepal, epidemics resembling FWB have been increasingly observed on Malbhog cultivar in past several years. However, disease has not officially reported yet, and consequently, little known about pathogen present across country. this study, we characterized 13 fungal strains isolated from plants (Silk, AAB) showing symptoms similar to plantations Nepal. All were typed...
A field experiment was conducted on fourteen rice varieties to determine the level of resistance against brown leaf spot (Bipolaris oryzae)disease at Karma Research and Development Center, Jyotinagar, Chitwan during summer in 2013. Design used randomized completeblock design with three replications. Disease severity, total AUDPC value, thousand grain weight yield were highly significant amongthe varieties. severity value ranged from 21.73% 58.07% 614.8 1827 respectively. None thesevarieties...
Spot blotch disease of wheat caused by Bipolaris sorokiniana; is one the most concerning in warm and humid regions Nepal due to its widespread prevalence increasing severity. An in-vitro experiment was conducted evaluate efficacy different botanicals fungicides against sorokiniana, National Plant Pathology Research Centre’s laboratory at Khumaltar, Lalitpur 2019. The done completely randomized design with three replications poison food technique. Five viz. neem, garlic, eucalyptus, bojho...
Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. is considered as one of the major threats to rice production in Nepal. To identify effective control measures, an experiment was done a randomized complete block design with three replications farmer's field at Bhaktapur, during summer seasons 2018 and 2019. Three plants extracts; 1% Neem extract, 2% Asuro Titepati extract along two fungicides viz. 0.1% Agricin 0.2% Blitox 50, bio-control agent 1%Kisan Pseudomonas were used...
Rhizoctonia solani and Alternaria citri are major plant pathogens of citrus, causing considerable production losses. Chemical fungicides widely used for disease control. Using the food poisoning technique under in vitro conditions, an experiment was undertaken to investigate efficacy several against those pathogens. To evaluate effect on mycelial growth, five different chemicals, viz. SAAF (Carbendazim 12% WP + Mancozeb 63% WP), Bavistin 50% VACOMIL PLUS (Metalaxyl 15% Copper oxychloride 35%...
A study was conducted during June to September, 2012, in the field at National Maize Research Program, Rampur, Chitwan, Nepal with objective of screening 20 maize genotypes against southern leaf blight caused by Bipolaris maydis. Experiment laid out a randomized complete block design three replications. Disease scoring done as percentage area infected on individual plant 7 days intervals starting from 50 after sowing, for 6 times, and disease severity mean AUDPC were calculated yield...
Blast, caused by Pyriculariagrisea (Sacc.) is the most destructive disease of rice in Nepal. To identify sources leaf blast resistance genotypes, a field experiment was conducted under natural epiphytotic condition at National Plant Pathology Research Centre (NPPRC), Khumaltar, Lalitpur, Nepal during summer season 2018 and 2019.A total 128 genotypes 291during 2019 including resistant check (Sabitri) susceptible (Shankharika/Mansuli) were tested. Field single rod row design. Leaf assessment...
Stalk rot of maize (Zea mays L.) is becoming a serious threat in tropical and subtropical growing regions Nepal. To identify the sources disease resistance genotypes, field experiment was conducted under natural epiphytotic condition during summer season 2016 2017 with thirty genotypes randomized complete block design two replications. Statistical analysis showed that percent incidence (PDI) grain yield were highly significant among tested genotypes. Most resistant to moderately resistant,...
Stripe rust disease is a major problem for wheat production in the hills of Nepal. To find resistance sources against this disease, 444 and 457 genotypes received from National Wheat Research Program, Bhairahawa 2018 2019 respectively were evaluated at Khumaltar under inoculated high pressure field condition. Disease was both seedling adult stages. In 2018, 315 showed stage while 89 having plant (APR). Also, 71 entries immune response 191 resistant Similarly 2019, 233 201 showing APR....
Banana is affected by a wide number of diseases, which, Fusarium wilt caused oxysporum f.sp. cubense has played major role in devastating Malbhog (Silk) banana plantations Nepal. The objective this study was to evaluate the commonly available fungicides (Carbendazim 50%, Fenamidone 10%+ Mancozeb Chlorothalonil and biocontrol agents (Trichoderma sps., Bacillus thuringiensis Pseudomonas species) for their efficacy against Foc. effectiveness Foc examined screenhouse. experiment laid out...
