A Benzothiadiazole derivate promotes experimental control of bacterial speck (Pseudomonas syringae pv. tomato) by activating constitutive host defenses
Thirty day old tomato plants (TopSeed), greenhouse grown, were sprayed with a water solution of BTH, a benzothiadiazole daivate, at 250μg/ml, one week before being artificially inoculated with two challenging pathogens: Alteman'a solani (inoculum equivalent to 10³ coniadia/ml) and Pseudomonas s...

| Resumo: | Thirty day old tomato plants (TopSeed), greenhouse grown, were sprayed with a water solution of BTH, a benzothiadiazole daivate, at 250μg/ml, one week before being artificially inoculated with two challenging pathogens: Alteman'a solani (inoculum equivalent to 10³ coniadia/ml) and Pseudomonas syringae pv. tomato (inoculum equivalent to OD540 = 0.1). In both cases, a number of lesions per leaílet was countod seven days later and compared with the number in the control plants, which had not been. exposed to the activator. A good protection was achieved when the challenger pathogen was Pseudomonas syringae pv. tomato, but the compound was ineffective against Alternaria solani. |
