Log transformed mean values of (A) soil nematode (J2s), (B) root nematode (J2s and eggs) population and (C) yield of lettuce plants treated with BPL. Bars having same case letters are not significantly different at P≤ 0.05. Control= inoculated untreated lettuce plants; CBFN1 = Carbofuran 5g; CBFN2 = Carbofuran 10g; CBFN3 = Carbofuran 15g; BMBO1 = PL 100mg/ml; BMBO2 = PL 200mg/ml); BMBO3 = PL 400mg/m.
