Maize (Zea mays L.) is a major food and fodder crop cultivated on 1.54 million ha in the Democratic Republic of Congo (DRC). In December 2013, unusually severe chlorotic mottle symptoms pale green streaks were observed local varieties (Mudishi 1 2, Bambou, Kasayi, H614, H613, Mugamba) exotic (H520, H624, H403, HDK8031, ZM607) Beni, Lubero, Rutshuru territories at 1,015 to 1,748 m elevation North Kivu Province. Symptoms prominent newly emerging leaves that later developed marginal necrosis...
Ascochyta blight (AB) of pulse crops (chickpea, field pea, and lentils) causes yield loss in Montana, where 1.2 million acres was planted to pulses 2016. Pyraclostrobin azoxystrobin, quinone outside inhibitor (QoI) fungicides, have been the choice farmers for management ascochyta pulses. However, a G143A mutation cytochrome b gene has reported confer resistance QoI fungicides. A total 990 isolates blight-causing fungi were isolated screened resistance. Out these, 10% from chickpea, 81% dry...
Didymella pisi is the predominant causal pathogen of ascochyta blight dry pea causing yield losses in Montana, where 415 000 acres were planted to 2018. Thirty-three microsatellite markers developed for pathogenic fungus, pisi, these used analyze genetic diversity and population structure 205 isolates from four different geographical regions Montana. These loci produced a total 216 alleles with an average 1.63 per marker. The polymorphic information content values ranged 0.020 0.990 0.323....
Montana leads the production of dry pea in United States. About 530,000 acres were planted to 2019, accounting for 48% total national ( USDA-NASS 2019 ). A predominant foliar disease is Ascochyta blight, which caused by multiple fungal pathogens including Didymella pisi, Peyronellaea pinodes, and pinodella. D. pisi pathogen causing blight Montana. Recently, an anticipated shift composition has been observed northeastern from P. pinodes. Also, a Phoma sp. was found associated with infected...
Didymella pisi is the primary causal pathogen of Ascochyta blight (AB) dry pea in Montana. Diagnosis AB challenging because there are six different species that cause worldwide and can co-occur. Additionally, agar plate identification D. due to its slow growth rate. Currently, no PCR-based assays developed for specific detection or any fungal complex pea. In this study, we evaluated simple sequence repeat (SSR) primer pairs their specificity sensitivity real-time conventional SSR-PCR both...
