LAKHDARI Wassima, Diagnosis of phytopathogenic fungi of Lycopersicon esculentum L. in Oued Righ region (Algerian sahara)(2017)SDRP Journal of Plant Science 1(1): 22-27
Background: Several phytopatogenic fungi attack tomato (Lycopersicon esculentum) plants in all the parts of this culture. In abundance use of chemical products we would like to investigate and produce molecules that can be used in biological control. This study was carried to study the fungal diseases of tomato plants in the region of Oued Righ.
Methods: The chosen field test area was naturally infested with several symptoms in the roots, leaves and fruits. Samples were brought to laboratory and plated out on potato dextrose agar (PDA) medium and incubated at 26°C.
Results: After isolation and identification, nine species of fungi were identified from the samples; Botrytis cinerea, Alternaria sp., Fusarium oxysporum f. sp. radicis-lycopersici, Cladosporium fulvum, Aspergillus niger, Penicillium sp., Stemphylium solani, Trichothecium roseum and Sclerotinia sclerotiorum. On the other hand, three species of these isolates were not identified.
Conclusion: As a first step to isolate and identify these phytopatogenic fungi, we have to use biological molecules to fight against these diseases, also to be useful in developing novel and environmentally safe strategies to control economically important.
