Figure 1.

Effects of soil treatments with 1,3-dichloropropene (1,3-D), Trichoderma harzianum (TH) and an organic fertilizer (OF), either alone or in combination, on final population density (A) and root gall infestation (B) of Meloidogyne incognita in two consecutive tomato crops. NT = non-treated control. Bars show the average of n = 4 replicates of each treatment ± standard error. Within each tomato crop, bars marked by the same letters are not significantly different, according to the least significant difference test (p ≤ 0.05).
