Vescicular-arbuscular mychorrhyzal fungi are naturally present in the roots of most fruit trees, and establish a mutualistic association with the plant, which results in an improved resistance to abiotic and biotic stresses. The presence of non-pathogenic rhyzosphere bacteria may induce a systemic resistance (ISR) in plants. Few natural or synthetic compounds, among which chitosan, widely present in nature and not very toxic to the plant, and benzo (1,2,3) thiadiazole-7-carbothioic acid S-methyl ester (BTH), may also induce the activation of the plant defence machinery against several pathogens. Delay of syndrome development and of plant death has been used to evaluate the activity of 1) vescicular-arbuscular fungi Glomus mosseae and G. intraradices, 2) rhyzobacteria Pseudomonas sp. S1PF1, and 3084 and Streptomyces sp. Sb20, 3) chitosan and 4) BTH as inducers of resistance against chrysanthemum yellows phytoplasma infection of daisy (CY). While G. mosseae and P. putida S1PF1 slightly reduced the number of CY-infected plants and extended the life span of the affected plants, only 2.4 mM BTH provided some protection from the disease and a delay of the syndrome. Two concentration of chitosan dissolved in acetic or chloride acids were not effective, although some protection from the disease was present in plants sprayed only with acetic acid. Both acids induced phytotoxic effects on the daisy plants. The most promising biotic and abiotic treatments identified in this screening will be further studied following their application under controlled conditions. The possible interactions between elicitors and insect vectors will also be investigated. (literal)
