  1. Data are means of 10 replications; means, followed with the same letter within a column, are not different according to Duncan’s multiple-range test (P ≤ 0.05)
  2. aRoot-galling and egg-mass indices: 0–5 scale, where 0 = no root galling or egg mass, 1 = 1–2 root galling or egg mass, 2 = 3–10 root galling or egg mass, 3 = 11–30 root galling or egg mass, 4 = 31–100 root galling or egg mass, and 5 = > 100 root galling or egg mass per root system
