A multiplex polymerase chain reaction (PCR) assay for simultaneous, fast and reliable detection of the main soft rot and blackleg potato pathogens in Europe has been developed. It utilises three pairs of primers and enables detection of three groups of pectinolytic bacteria frequently found in potato, namely: Pectobacterium atrosepticum, Pectobacterium carotovorum subsp. carotovorum together wi...

In an experimental study of adaptation to negative pleiotropic effects of a major fungicide resistance mutation in the filamentous fungus Aspergillus nidulans we have investigated the relative effectiveness of artificial selection vs. natural selection on the rate of compensatory evolution. Using mycelial growth rate as a fitness measure, artificial selection involved the weekly transfer of the...

the aim of the present work was to purify cysteine protease inhibitors from rapeseed (brassica napus l.), with potential activity on digestive protease of colorado potato beetle (cpb), leptinotarsa decemlineata (say). ammonium sulfate precipitated proteinaceous fractions; 30, 50, 70, and 100% showed 39.07, 57.03, 51.47, and 22.44% inhibition on the fourth instar larval gut general protease acti...

The paper presents the data on a long term dynamics of occurrence and development moniliosis in cherry plants. It’s established that during research blossom blight sprouts was 1,6–59,7 %, fruit rot – 0,2–27,4 %. doesn’t depend age crop. biological efficiency copper fungicide Indigo, CS studied. applied dose 3,0–5,0 l/ha to amounted 2020: 77,8–88,1 % for limitation sprouts, 86,0–92,0 rot; 2021: ...

Botryosphaeria canker of Quercus suber (causal agent: Diplodia corticola) poses a major threat for cork production along the western Mediterranean Basin. Infection by D. corticola induces cankers, which reduce tree vigour and compromise phellem regeneration. European policies in forest health advise use environmentally friendly methods, such as biocontrol, rather than chemicals natural stands. ...

fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (vcgs) and rep-pcr dna fingerprinting. nit ...

to evaluate the influence of arbuscular mycorrhizal inoculation on growth, yield and minituber production of potato plantlets, a pot experiment was conducted using a factorial based on completely randomized design with four replications. the factors were mycorrizal inoculation (non-inoculated and inoculated with glomus mosseae, glomus etunicatum and mixed of them) and two potato cultivars (agri...

Peanut (Arachis hypogaea L.) remains an important agronomic crop in Alabama, Florida, and Georgia. In recent years, the value of Alabama’s 190,000-acre peanut crop has exceeded $120 million annually. However, the diseases early leaf spot, late leaf spot, and southern stem rot may greatly reduce the profitability of Alabama’s peanut crop due to lower yields and poorer nut quality (7). Also, fung...

melon and musk melon are grown widely in warm and moderate climate regions of the world as well as iran. these crops are attacked by several fungal pathogens including macrophomina phaseolina which causes charcoal rot disease at different growth stages and reduces the yield remarkably. fungicide application and other control methods have not been successful in control of charcoal rot and utiliz...
