Suppression of Meloiodogyne incognita (Tylenchida: Heteroderidae) and Tylenchulus semipenterans (Tylenchida: Tylenchulidae) using Tilapia fish powder and plant growth promoting rhizobacteria in vivo and in vitro

Abstract Plant-parasitic nematodes (PPNs) in particular those belonging to the genera Meloidogyne and Tylenchulus are a limiting factor production of many plants. In this research, we investigate strategy for control PPNs vivo vitro. The purpose research is evaluate different concentrations Tilapia fish powder (TFP) (in form BECTO Grow Roots®) against egg hatching second-stage juveniles Meloiodogyne incognita (Tylenchida: Heteroderidae) under laboratory condition. We also assessed effect TFP on M. semipenterans Tylenchulidae) reproduction. Our data showed that percentage inhibition ranged from 8.03 53.21% 42.25 75.12% after five days treatment at PGPR, respectively compared with control. J2 mortality increase significantly ( p ≤ 0.05) 52.1 86.7 44.6 92.3% seven Under greenhouse conditions, remarkable plant growth parameters was observed cucumber plants received field experiment, highest reduction T. semipeneterans density + PGPR This holds both healthy infected trees. Healthy navel orange (HNO) achieved maximum enhancement weight/tree other treatments. study recommended not only because their potential nematodes, but safety humans, mammals non-target organisms.
