...ue to root rot fungi and root-knot nematode cause huge losses to cotton. Experiments were conducted to assess the role of fungi and root knot nematodes in root rot disease complex of cotton and to optimize their control. For this purpose fifteen cotton growing areas in Southern Punjab were surveyed in year 2013-14. Data were recorded on disease prevalence, incidence, frequency percent of root rot fungi and nematodes population. Maximum disease prevalence was r...

... seriously threatened by root-knot nematodes. As the damaging effects of Meloidogyne incognita have not been assessed on cucumber, therefore, the present studies report the effects of five initial population densities of M. incognita on growth and yield of cucumber and nematode reproduction. All inoculum densities caused significant reductions in growth and yield of cucumber and were found to be positively correlated with the latter. On the other...

The attraction intensity was directly proportional to time and based on the nutrients provided by the nematodes. In this experiment, the nematophagous fungi Arthrobotrys oligospora, A. superba, A. musiformis, Dactylella oviparasitica, Clonostachys rosea, Stropharia rugosoannulata, Lecanicillium muscarium, Trichoderma harzianum, T. viride, Pleurot...

As very little information is available on the distribution of root-knot nematodes in okra plantations, therefore, in the present studies surveys were conducted to record incidence, prevalence, and severity of root-knot nematode species associated with okra in the major vegetable growing districts of the Punjab provinc...

The minimum mortality was recorded with 25 mg/ml of AgNP. With the increase in concentration, there was a corresponding increase in the mortality of juveniles showing a direct relationship between mortality and concentration of nanoparticles. The effect of time on mortality was...

All fungi and chemicals proved to be efficient in reducing the infestation level of Meloidogyne hapla and providing better growth of carrots compared to their controls. Maximum reductions in nematode population were observed in the plants treated with Lecanicillium muscarium and both chemicals. Lecanicillium muscarium treatment...

... the interaction between root-knot nematodes and bacterial wilt is lacking in chili, therefore, in the present study, effects of Meloidogyne javanica and Ralstonia solanacearum were studied on chili singly and in combinations. Significant effects of M. javanica and R. solanacearum and their interaction were observed in case of shoot and root lengths and weights of chili. The mean lengths and weights of shoot and root varied signific...

The attack of root-knot nematodes (Meloidogyne spp.) has been reported as the most serious, widespread and alarming which causes tremendous yield losses (Hussain et al., 2011; Kayani et al., 2013; Barros et al., 2014). Flea beetle (Podagrica spp.) is the most important insect pest of okra in Ghana and Nigeria (Obeng-Ofori & Sackey, 2003; AsareBediako et al., 2014a, Mobolade et al., 2014). It has been estimated that insect pests attack led to gre...

All selected plant species inhibited egg hatching and caused larval mortality. Maximum reduction (24.3%) in egg hatching was recorded in C. album stem extract at 2% concentration. The minimum reduction (0.33%) was observed in the leaf extract of A. viridis at...
