“…En effet, la stimulation du « système immunitaire » des plantes provoque l'activation d'une série de réactions biochimiques qui aboutissent à la synthèse de nouvelles molécules organiques, dont notamment des protéines PR et des phytoalexines. Pour Lyon et Newton (1997), les protéines PR sont des molécules communes à toutes les plantes et leur production accrue sous l'action d'un éliciteur ne devrait pas poser de problèmes majeurs. Cependant, plusieurs études, dont celles d 'Ebner et al (2001) et, plus récemment, d'Andersen et al (2011, soulignent le pouvoir allergène de certaines protéines PR, notamment celui des PR10 qui sont des protéines proches des ribonucléases; cet aspect mérite d'être plus pré-cisément examiné.…”

“…Elicitors of induced resistance to arthropods do not, as noted above, typically induce immunity to herbivores; furthermore, there is often a delay from the time of application of an Archives of Insect Biochemistry and Physiology elicitor to the time of expression of responses. For these reasons, elicitors will possess poor curative properties and will be most effective when applied before infestations become severe (Lyon and Newton, 1997). Fortunately, because reliable information about the phenology of pest infestations in crop plants is often available to producers, timely prophylactic applications of elicitors should be possible for many crops.…”

Plants protect themselves from arthropod herbivores both directly, by expressing biochemical and morphological traits that interfere with herbivore development or behavior, and indirectly, by facilitating the action of natural enemies of herbivores. These direct and indirect resistance mechanisms are not always expressed at maximal levels by plants, but rather can be induced to higher levels by a variety of stimuli, most notably prior herbivory. The recent discovery of chemical elicitors of induced responses has led to interest in manipulating the inducible responses of plants for crop protection. Applications of elicitors of induced responses made at appropriate times during the growing season of a crop have the potential of activating both direct and indirect mechanisms of plant resistance and thereby simultaneously augmenting host-plant resistance and biological control. This strategy may serve as an important component of a multifaceted, ecologically-based pest management program and is unlikely to precipitate the rapid evolution of countermeasures by target pests. However, this strategy will not be appropriate in all crops or against all arthropod pests. The conditions under which the use of an elicitor is likely to be successful are discussed, and examples of the successful use of elicitors are reviewed.

RESUMONa busca por novos indutores de resistência contra a vassoura-de-bruxa no cacaueiro avaliou-se o efeito de vários nutrientes, acibenzolar-S-metil (ASM) e a combinação desses nutrientes com ASM. Os produtos e as misturas foram pulverizados 30 dias antes da inoculação nas mudas do clone SIC-23. Foram utilizados os produtos comerciais Supa-potássio (silicato de potássio), Hortifós PK (fosfito de potássio) e Broadacre Mn (sulfato de manganês), testados nas dosagens 2,5 mL; 5,0 mL; 10 mL/L de água, isoladamente ou combinados com ASM (0,2g/L). O experimento foi conduzido no delineamento de blocos ao acaso, no esquema fatorial, com quatro repetições de doze plantas/parcela. A incidência da doença foi avaliada 60 dias após a inoculação. Somente o ASM promoveu controle significativo da vassoura-de-bruxa. Os nutrientes aplicados isoladamente não apresentaram efeito na severidade da doença. Por outro lado, o efeito protetor do ASM desapareceu quando este foi misturado ao Supa-potássio , na dose de 5 ou 10 mL/L. Termos para indexação:Resistência induzida, ASM, fosfitos, silicatos, manganês, Crinipellis perniciosa. ABSTRACTAiming at improving the level of induction of resistance in cocoa, various nutrients, acibenzolar-S-methyl (ASM) and their combination were tested on cocoa seedlings, clone SIC-23, 30 days before inoculation. The commercial products Supa-potássio (potassium silicate), Hortifós PK (potassium phosphite) and Broadacre Mn (manganese sulfate) were sprayed at doses of 2.5, 5.0 mL and 10.0 mL per liter of water, combined or not, with ASM (0.2 g/L). The experiment was set in a randomized block design, in a factorial scheme, with four replicates of twelve plants each. Disease incidence was assessed 60 days after inoculation. Only ASM promoted significant control of the disease. Nutrients alone had no effect on disease incidence. On the other hand, the protective effect of ASM disappeared when this product was mixed to Supa-potássio at 5 or 10 mL/L.
