Kurzfassung:
The efficacy of a formulated product of tea tree oil (TTO) and a standard
copper based bactericide in combinations with acibenzolar-S-methyl (ASM) for
control of bacterial spot of pepper and bacterial speck of tomato was
evaluated under controlled conditions. Treatments with copper hydroxide+ASM
at both application rates and TTO+ASM showed the best efficacy in control of
bacterial spot disease in pepper plants (with respective efficacy values
83.5%, 83.7 % and 86.9%). Similar efficacy was achieved by treatment with
copper hydroxide alone (82.2%). On the other hand, the efficacy of TTO,
applied alone, was significantly lower at both rates (63.8% and 71.5%) in
bacterial spot control in pepper. The same treatments (copper hydroxide +ASM
at both application rates and TTO+ASM) were most efficient in suppressing
the causal agent of bacterial speck disease in tomato (87%, 82.3% and
81.6%). The efficacy of treatment with the standard bactericide copper
hydroxide, applied alone, was significantly lower compared to its
combination with ASM (79.1%). Similarly to the bacterial spot experiment,
TTO treatments alone showed lower, although satisfactory efficacy at both
application rates (66.1% and 68.9%). The results of this study showed that
combination of the bioactive compound - ASM with either the standard copper
hydroxide bactericide or TTO significantly improved their efficacy in both
bacterial spot and speck disease control, and thus implied that combining
different biorational compounds, such as essential oils and bioactive
products, with standard copper treatments and their inclusion into
integrated management programs are of essential importance for the control
of bacterial diseases of pepper and tomato.
