Figure 1:
Nematode population densities in soil in Trials 1 and 2 of the field experiment. (A) Free-living nematodes; (B) root-lesion nematodes (Pratylenchus zeae and P. coffeae), and (C) spiral nematodes (Helicotylenchus sp.). Each bar is the mean of four replicates±standard deviation.
Figure 2:
Root-lesion nematode (Pratylenchus zeae) densities in sugarcane roots in Trials 1 and 2 of the field experiment. Nematodes were extracted from roots at (A) three months after planting and (B) six months after planting. Each bar is the mean of 16 replicates±standard deviation. Asterisks indicate significant difference from the control (**P<0.01 and ***P<0.001). There was an interaction between treatment and trial (P<0.05) for the three-month analysis.
Figure 3:
Effect of fipronil treatment on sugarcane yield in Trials 1 and 2 of the field experiment. (A) Millable stalk weight; (B) Number of millable stalks; (C) Single stalk weight; (D) Stalk length; (E) Millable stalk diameter; and (F) Brix. Each bar is the mean of 16 replicates ± standard deviation (*P < 0.05). Different letters indicate significant difference (P < 0.05) between the treatments when the trials were analyzed together in ANOVA. There was no interaction between treatment and trial.
