Figure 1.

Biological control efficacy – BCE (%) of plant extracts against bacterial wilt in potato plants in seasons A and B 2021 on various days after extract injection – DAIBCE = [(DInegative control − DItreatment)/DInegative control] × 100; negative control – 1% DMSO, positive control – 2% copper oxychloride; values with the same letter in the same season and measurement term are not significantly different at p ≤ 0.05, according to Tukey’s test; error bars represent the standard deviation
