Abstract The nematicidal efficiency of two types extracts (aqueous and methanolic) 5 plants Peganum harmala L., Raphanus raphanistrum L . , Taxus baccata Sinapis arvensis Ricinus communis L. on second stage juveniles (J2s) Meloidogyne incognita was evaluated at 4 doses in vitro (40, 50, 60 80%) exposure times (12, 16, 24, 32 h). In a greenhouse, methanol obtained from 0.75, 1.5, or 3 g the dry matter T. S. P. were added pots tomato (Moneymaker cultivar) to test effect nematode, its...
This study evaluated the mycoherbicidal potential of Alternaria alternata (Fries.) Kiessler on cocklebur (Xanthium strumarium L.), a noxious weed in Algeria. Conidial suspension, rapeseed-oil-based liquid formulation and sodium-alginate-based solid formulation, all with 106 conidia/ml, as well herbicide (Mustang®) at reduced dose (0.45 L/ha) were compared. Inoculum was applied detached leaves under laboratory conditions 4–5 leaf stage seedlings pots greenhouse field. Disease severity highest...
Alternaria alternata isolates C1, S1, and X3 were isolated respectively from the weeds Convolvulus arvensis, Sonchus oleraceus, Xanthium strumarium in Algiers during 2016 identified by morphological molecular analyses. The aim of this investigation was to chemically characterize exometabolome these fungi evaluate myco-herbicidal potential their culture filtrates, crude extracts, or fractions towards target weeds. Results revealed a great heterogeneity biochemical profiles with remarkable...
Abstract Alternaria leaf spot caused by alternata (Fries.) Kiessler was found on sow thistle ( Sonchus oleraceus L.) and field bindweed Convolvulus arvensis in the experimental station of ENSA (Ecole Nationale Supérieure d'Agronomie) Algiers, Algeria, during winter 2016. Necrotic spots form concentric circles were observed leaves both weeds with disease incidence approximately 70% severity ranging from 50% to 70%. Fungi isolated infected identified as A. , based morphological molecular...
