Abstract

Haseeb et al. / J Zhejiang Univ SCI 2005 6B(8):736-Abstract: Studies were conducted under pot conditions to determine the comparative efficacy of carbofuran at 1 mg a.i./kg soil, bavistin at 1 mg a.i./kg soil, neem (Azadirachta indica) seed powder at 50 mg/kg soil, green mould (Trichoderma harzianum) at 50.0 ml/kg soil, rhizobacteria (Pseudomonas fluorescens) at 50.0 ml/kg soil against root-knot nematode, Meloidogyne incognita-wilt fungus, Fusarium oxysporum disease complex on green gram, Vigna radiata cv ML-1108. All the treatments significantly improved the growth of the plants as compared to untreated inoculated plants. Analysis of data showed that carbofuran and A. indica seed powder increased plant growth and yield significantly more in comparison to bavistin and P. fluorescens. Carbofuran was highly effective against nematode, bavistin against fungus, A. indica seed powder against both the pathogens and both the bioagents were moderately effective against both the pathogens.

Comparative study of <i>Fusarium oxysporum</i> f sp. <i>lycopersici</i> and <i>Meloidogyne incognita</i> race-2 on plant growth parameters of tomato

“…Higher multiplication rate for low initial population and low multiplication rate in high initial population was observed. Same results were also observed by Brker et al [22], Di Vito and Ekanayake [23] and Haseeb et al [24]. It can be concluded from these results that the damaging threshold levels of M. incognita race 2 on tomato was found to be as 1000 J 2 /kg soil while threshold level of fungus, Fusarium oxysporum f sp.…”

Seed borne fungi of Chilli Pepper (Capsicum frutescens) from pepper producing areas of Benue State, Nigeria

“…Plant parasitic nematodes interact with fungi to cause plant disease complexes and may also increase the severity of disease (Senthamarai et al, 2008). According to Haseeb et al (2005) low densities of fungi or nematode can result in a disease complex of significant importance. Associations between fungi and nematodes have been found to cause brown rot of tobacco.…”

Biological control of Meloidogyne incognita by Trichoderma harzianum and Serratia marcescens and their related enzymatic changes in tomato roots

“…These local isolates that proved to be promising in a preliminary study were designated as f1, f3 and f8 and cultured on intact sorghum seeds (Haseeb et al, 2005). The final concentration per plate was set at 10 8 CFU/g of the seeds.…”
