In summary, the development of a portable DRS method for pre-symptomatic detection of late blight disease in potato leaves represents a significant advancement in the field of plant disease diagnostics. The method has the potential to improve crop yields and reduce economi...
were simultaneously identified at a mixed infection rate of 14.67% in the present study. The pathogenicity test results showed thatF. proliferatumandF. fujikuroiexhibited the highest virulence, with average disease indices of 30.28 ± 2.87 and 28.06 ± 1.96, followed byF. equisetiandF...
The Sclerotinia diseases are known under a variety of names and the most common of these along with some of the host plants most seriously affected are the cottony rot, white mould, or watery soft rot of beans, cabbage, carrot, eggplant, citrus, peanut, potato, stock, tobacco etc.; stem...
In the first trial, disease severity in AMF pre-colonized potato plants was markedly decreased and the onset of late blight symptoms was delayed by 10 days. In contrast, in the second trial no differences were noticed between AMF pre-colonized and control plants. In both trials, no ...
late blightresistance mechanismhyper-sensitive responseThe effect of temperature and photoperiod on the expression of resistance against Phytophthora infestans in five potato cultivars with and without resistance (R) genes was investigated. Four experiments were carried out under controlled conditions in ...
The objective of this study was to isolate and identify the causal agent of the disease. Isolations from diseased alfalfa plants showing visible blight and necrotic symptoms collected from the infected field were made on potato dextrose agar (PDA). Morphological observations of the developing fungal...
These mutants harbored one (sfb1) or more copies (sfb2 and k202) of the mutagenic plasmid, pHygR. The three mutants had similar biological attributes; that is, vegetative growth rate, conidiation and virulence (assay on apples) was reduced on potato dextrose agar media, relative to the ...

Rice bacterial blight is a deadly bacterial disease that is among the most destructive afflictions of cultivated rice. In severe epidemics, crop loss may be as high as 75 percent, and millions of hectares of rice are infected annually.
