To Investigate the Efficacy of the Nematicide imicyafos (Nemakick® SL 30%) in Controlling of Root Knot Nematode, M. javanica, in Cucumber under Glasshouse Conditions

Nematodes especially root knot nematode, Meloidogyne javanica, are amongst the factors responsible for reducing the production of cucumber which is a suitable host for this pest. In order to investigate the efficacy of the nematicide Imicyafos (Nemakick 30% SL) four concentrations 1, 2.5, 5 and 10 l/ha of a commercial form of this nematicide  and 150 kg/ha of nemaphos (nemacur 10% G) were applied to the soil at the time of transplanting cucumber seedlings and a week earlier respectively on Sultan variety cucumber. Nemakick was able to reduce the nematode population effectively compared with the control treatment. At the dose of  2.5 and 10 l/ha it reduced the final pest density by 75% and reproduction factor by 45% but it was ineffective at the dose of  1 l/h. Nemacur  at the same  doses  as  Nemakick, decreased the nematode infestation by 49% compared with the  untreated control. Nemakick at 2/5 l/ha commercial form dose could be recommended to be used for controlling M. javanica in greenhouse cucumber production.
