Abstract
A greenhouse experiment was conducted to assess the impact of five commercial biopesticides on root knot nematode, Meloidogyne incognita infecting pepper plants cv. Kortoba. Biopesticides used in the present study were: Anti-Nema (Serratia marcescens) Bio-Arc (Bacillus megaterium), Bio-Zeid (Trichoderma album), Bio-Nematon (Purpureocillium lilacinum), and Nema-Stop (Streptomyces avermitilis), compared to chemical nematicide, Krenkel as well as untreated check. All biopesticides were applied as soil drench after nematode inoculation (1000 M. incognita second stagejuveniles) which spread around the base of plant. Applications of such biopesticides achieved a significant (P≤ 0.05) improvement in plant growth parameters and significant suppression in nematode population. Bio-Arc recorded maximum values in improving total plant fresh weight (89.7%), plant length (123.0%), and shoot dry weight (143.8%), followed by Bio-Zeid. Also, Bio-Arc recorded the highest percentages of reduction in number of juveniles in soil, root galling and egg masses with values 66.06, 65.79 and 62.32% respectively comparing to nematode alone. Furthermore, it is also worth noting that the majority of treatments had the same values for both root gall and egg masses indices (2.0) compared to nematode alone (3.0).
