Abstract:
Cucumber (Cucumis sativum) is a warm season vegetable grown throughout the world under tropical and subtropical condition in open fields. The climatic suitability of crops is also favorable for many diseases. Among them disease complex situation causes severe loss. The simultaneous penetration of nematode and fungus exhibited a synergistic effect on growth retardation of plants. In view of this, the experiment was conducted on effect of cucumber plant age on development of wilt complex caused by nematode and fungus interaction. The fungus and nematode (2 J₂ per gram soil) simultaneously inoculated in soil at the time of sowing, 7, 14, 21 and 28 days after sowing (DAS). Data showed that maximum plant growth parameters, minimum nematode reproduction and minimum PDI were recorded in inoculum after 28 days of sowing followed by 21 days and 14 days after sowing While, minimum plant growth parameters, maximum nematode reproduction and maximum PDI were recorded with inoculated at the time of sowing.
