A giboma é uma hortaliça da família das solanácea originária África e muito cultivada neste continente emergente no Brasil. Os nematoides de galhas, gênero Meloidogyne, causam grandes prejuízos nas hortaliças, com destaque para as solanáceas. Assim, objetivou-se avaliar a influência concentração inóculo inicial M. javanica desenvolvimento giboma. Utilizou-se o delineamento inteiramente casualiz...

abstract in this study the effect of combination of trichoderma harzianum bi and salicylic acid were studied on root knot nematode (meloidogyne javanica) disease on tomato under green house conditions. the roots of tomato seedlings at six-leaf stage were inoculated with suspensions of fungal antagonist (106 conidia/ ml), 5mm salicylic acid and 2000 second-stage juvenile (j2). combined applicati...

Meloidogyne enterolobii is widely considered to be an aggressive root-knot nematode species that is able to reproduce on root-knot nematode-resistant tomato and pepper cultivars. In greenhouse experiments, M. enterolobii isolates 1 and 2 from Switzerland were able to reproduce on tomato cultivars carrying the Mi-1 resistance gene as well as an N-carrying pepper cultivar. Reproduction factors (R...

Ozone gas (O₃) is a reactive oxidizing agent with biocidal properties. Because of the current phasing out of methyl bromide, investigations on the use of ozone gas as a soil-fumigant were conducted. Ozone gas was produced at a concentration of 1% in air by a conventional electrical discharge O₃ generator. Two O₃ dosages and three gas flow rates were tested on a sandy loam soil collected from a ...

Root-knot nematodes (Meloidogyne spp.) represent one of the most polyphagous genera of plant-parasitic nematodes. To date, close to 100 valid species are recognized. In contrast to the size of the genus, the majority of past research focused on a small number of species, i.e., the so-called 'major' species M. arenaria, M. hapla, M. incognita, and M. javanica. This review highlights recent work ...
