Abstract Purpose Wheat sheath blight mainly infected by Rhizoctonia cerealis is one of the soil-borne fungal diseases wheat worldwide and prevalent in major growing areas China at present. This study aimed to evaluate antifungal activity 163 endophytic fungi on R. . Antifungal strains were identified their biosynthetic potential was analysed. Methods The evaluated via dual-culture antagonism as...

Several diketopiperazines have been isolated from liquid cultures of Alternaria alternata, the causal agent of black leaf blight of spotted knapweed, Centaurea maculosa Lam. One of these compounds, maculosin [the diketopiperazine cyclo(-L-Pro-L-Tyr-)], was active in the nicked-leaf bioassay at 10(-5) M; synthetic maculosin possessed chemical and biological activities identical to those of the n...

Some elicitors of plant defensive systems can induce biochemical changes that enable the plant to reduce disease incidence; however, little is known about the effect of these induced responses on insect herbivores. We approached this problem using exogenous field applications of several abiotic elicitors of defensive systems in tomatoes (Lycopersicon esculentum), and evaluated the ability of th...

Mustard (Brassica juncea L.) is the second most important oilseed commodity in India. Alternaria blight (Alternaria brassicae) one of devastating fungal pathogen, resulting severe yield losses to crop. The present study conducted in-vitro know effect different temperature regimes and various culture media on mycelial growth sporulation A. brassicae. It clearly evident from results that all test...
