Abstract Verticillium longisporum is a soil-borne vascular pathogen of oilseed rape and other Brassica crops. The limited availability chemical control measures against pathogens calls for the exploration alternatives. Cross-protection may be conveyed by use non-pathogenic or non-aggressive isolates potential as biocontrol agents. V. consists three lineages that originated from independent hybr...

Laboratory experiments were conducted to evaluate the effect of some commercially available biopesticidal formulations, such as Bacillus thuringiensis var. kurstaki (2g/l), sphaericus(2g/l), Beauveria bassiana (5g/l), Metarhizium anisopliae Lecanicillium lecanii (5g/l) on Temperature Tolerant strain Trichogramma chilonis (TTT). Two sets conducted, in first experiment, all test biopesticides spr...

Under adequate sulfur supply, plants accumulate sulfate in the vacuoles and use sulfur-containing metabolites as storage compounds. Under sulfur-limiting conditions, these pools of stored sulfur-compounds are depleted in order to balance the nitrogen to sulfur ratio for protein synthesis. Stress conditions like sulfur limitation and/or pathogen attack induce changes in the sulfate pool and the ...
