Greenhouse-cultivated tomato, bean and cucumber suffer great economic losses due to grey mould, caused by Botrytis cinerea. Benzothiadiazole (BTH) is a chemical analogue of salicylic acid that induces resistance in a variety of plants by activating the systemic acquired resistance (SAR) pathway. Here, we investigated the effects of foliar applications of(More)
