Description
Summary:For this reason, there is a great demand for plant protection alternatives, such as the use of nanocrystals. [...]the aim of this work was to evaluate the performance of nanocrystals spraying intervals for the control of tomato bacterial spot. 1Cu reduced the tomato bacterial spot severity when sprayed at 3- and 6-day intervals. [...]nanocrystals may be used for the tomato bacterial spot control when sprayed at 6-day intervals, once this interval is adequate and practical for disease management. RESULTS AND DISCUSSION To area under the disease progress curve (AUDPC), for tomato bacterial spot, no significant interaction was observed between the factors (products and spraying intervals). At 15 days after inoculation (Figure 1A, B, C, D) was observed an increase in the severity progress curve for tomato bacterial spot, especially in plants under the control treatment (water) and at 3, 6, 9, and 12-days spraying intervals.
