| Summary: | This research was performed to examine the protective activities of the mixtures of pine oil and copper
hydroxide against bacterial spot and anthracnose on pepper plants. As for bacterial spot, the treatment of
pine oil alone displayed high disease incidence (59.6%) and low protective effect (28.9%). In comparison, the
treatments of mixtures and copper hydroxide alone showed protective activities of 66.8-76.1%. The mixture
of pine oil and copper hydroxide (4:1) suppressed the most effectively bacterial spot on pepper. On the other
hand, the mixture of pine oil and copper hydroxide (4:1) also showed the strongest protective effect against
pepper anthracnose among the 4 treatments tested; its disease incidence and disease control value were
49.8% and 41.7%, respectively. The other treatments showed low protective activities with control values of
7.4-17.1%. These results suggested that the mixture of pine oil and copper hydroxide (4:1) can be used for the
environmental-friendly disease control of bacterial spot and anthracnose on pepper. |
