Abstract

In glasshouse conditions, a disease complex involving Meloidogyne incognita and Fusarium oxysporum f. sp. pisi was investigated on pea. The pot experiments were carried out to decide the pathogenic effects of pathogens individually as well as collaboratively. M. incognita and F. oxysporum f. sp. pisi, individually caused a significant reduction in plant height, fresh and dry weight, in comparison of un-inoculated control. Various plant growth parameters were observed significant related with the reduction of plant growth when simultaneous and sequential inoculation of M. incognita and F. oxysporum f. sp. pisi was done. However, the reduction was more prominent when both the pathogens inoculated simultaneous. Nematode multiplication, galls formation in numbers, egg masses, eggs/egg masses and population of nematode were adversely exaggerated on simultaneous and sequential inoculation of both the pathogens in all the treatments. It was concluded that both the pathogens viz., M. incognita and F. oxysporum f. sp. pisi are virulent against the pea Var. Kashi Nandini which defined the seriousness of disease and ultimately adaptation of management if such condition formed.

Conclusion

The above exploration obviously clarify the relation between M. incognita and Fusarium oxysporum f. sp. pisi and their role in causing the disease in pea. The above study reported that the nematode, M. incognita acts as predisposing agent for the invasion of F. oxysporum f. sp. pisi and their combined infestation reduced the plant growth parameters and significantly changes modified the biochemical components in the plant. Cohabitation of nematode-fungus should be given emphasis while formulating the management strategies for the successful supervision of the both pathogens.
