From: Silicon amendment induces synergistic plant defense mechanism against pink stem borer (Sesamia inferens Walker.) in finger millet (Eleusine coracana Gaertn.)

Figure 7

Silicon amendment reduces stem borer infestation in finger millet plants. (A). Effect of silicon on feeding tunnel length (cm) measured with/without Si Treatment at different time points. (B). Larval boring success percentage of S. inferens larvae on Si-treated and un-treated plants of finger millet on live stem in greenhouse and on detached stem in laboratory. Error bars represents ± SD (n = 5). The star above the bars graph represents different level significance obtained from paired t-test (*) at 0.05, (**) at 0.01 and (***) at 0.001 alpha levels respectively. (C). Development of dead heart symptom in finger millet plants after one week under different treatments. (D). Experimental set up for measuring tunnel length and boring percentage on live stem in response to Si treatment. (E–H). Representative images of symptoms develop after SB infestation on finger millet plants (E) dead heart (F) feeding tunnel (G,H) frass.
