EFFECT OF BIO-NEMATICIDE AND BAU-BIOFUNGICIDE AGAINST ROOT-KNOT (MELOIDOGYNE SPP.) OF SOYBEAN

Abstract

Meloidogyne spp. considered highly dangerous on soybeans. It is very difficult to find the suitable method for controlling without affecting on the environment. Therefore, in this study we used Four treatments with a newly developed Bio-nematicide, BAU-Biofungicide, Bio-nematicide + BAU-Biofungicide including control were tested against root-knot (Meloidogyne incognita) of two soybean varities (Sohag and BARI Soybean-5). The bio-agents were used as side dressing. Bio-nematicide in combination with BAU-Bio-fungicide showed the best performance with the highest length of shoot and root, fresh weight of shoot and root with nodules, weight of seeds and number of nodules per plant correspondingly with decreased number of galls and adult females of the nematode. Bio-nematicide and BAU-Biofungicide showed better performance in plant growth characters, yield of seeds and nodulation resulting in reduced galling and nematode development. BARI soybean-5 appeared with higher plant growth characters, nodulation and yield with reduced galling compared to variety Sohag. Positive response was observed with Bio-nematicide interacting with all the varieties of soybean. Negative correlation was found between gall numbers and all plants growth, nodulation and yield components. The combination between biological control agents is useful for the supporting and succeeding the biocontrol of Meloidogyne incognita. Thus, it is leading to save the environment from the residue of pesticides.
