Abstract

BackgroundApplication of organic amendments could improve soil properties as well as controlling of soil-borne pathogens. Soil amendments with dry powders of six plant species materials, i.e. caraway seeds, fennel seeds, garlic gloves, onion bulbs, pomegranate peel and spearmint leaves were separately applied for controlling Fusarium solani and Meloidogyne incognita on pea plants in pots. The control is untreated check pots for Fusarium solani and Meloidogyne incognita.ResultsThe dry powder of pomegranate peel (as the rate of 10 g/1 kg soil)highly reduced the Fusarium- disease assessments (pre-emergence and post-emergence damping-off and root-rot diseases incidence), followed by spearmint leaves, caraway seeds, fennel seeds, garlic gloves and onion bulbs, respectively. The tested dry powder of plant species showed the nematicidal activity on M. incognita criteria, i.e. second juvenile (J2) in soil and roots as well as galls and egg-masses in roots of pea. The spearmint leaves, onion bulbs and fennel seeds highly reduced the J2 in soil and roots as well as galls and egg-masses. The pea plant growth parameters i.e. length of shoot, fresh & dry weights of shoot and fresh weight of roots, yield parameters, i.e. fresh and dry weight of pea pod and pod parameters as well as Rhizobium nodules number were increased in pea plants with reducing infestation with F. solani and M. incognita.ConclusionsSoil amendments with dry powders of six plant species materials were used in this study reduced F. solani and M. incognita and improved pea plants

Highlights

Application of organic amendments could improve soil properties as well as controlling of soil-borne pathogens
The compost amended soil could reduce the percentages of disease incidence and improve the growth parameters of cucumber plants in pot experiments (Sabet et al 2013).The pomegranate peel aqueous extract inhibited the linear growth of Fusarium oxysporum and F. solani in vitro tests as well as pomegranate peel powder, when tested as seed or soil treatments, could decrease the pre- emergence and post-emergence of Fusarium damping-off disease in greenhouse experiments (Mohamad and Khalil 2015)
The obtained results are in agreement with those recorded by Borrego-Benjumea Ana et al (2015), where soil amended with poultry manure or olive residue compost significantly reduced inoculum viability of Fusarium oxysporum, F. proliferatum and F. solani associated with asparagus roots when affected with crown and root rot diseases

Summary

Introduction

Application of organic amendments could improve soil properties as well as controlling of soil-borne pathogens. Soil amendments with dry powders of six plant species materials, i.e. caraway seeds, fennel seeds, garlic gloves, onion bulbs, pomegranate peel and spearmint leaves were separately applied for controlling Fusarium solani and Meloidogyne incognita on pea plants in pots. Application of organic amendments could improve soil properties as well as controlling of soilborne pathogens, where the non-sterilized vegetables waste-compost completely inhibited the mycelium growth of Fusarium oxysporum f.sp radicislycopersici in tomatoes, at the highest rates only (Kouki et al 2012). The compost amended soil could reduce the percentages of disease incidence and improve the growth parameters of cucumber plants in pot experiments (Sabet et al 2013).The pomegranate peel aqueous extract inhibited the linear growth of Fusarium oxysporum and F. solani in vitro tests as well as pomegranate peel powder, when tested as seed or soil treatments, could decrease the pre- emergence and post-emergence of Fusarium damping-off disease in greenhouse experiments (Mohamad and Khalil 2015). The combination significantly reduced the wilting disease severity and increased the survival of lupine plants in field applications (Abou ElNour Mona et al 2020)
