BL Baheti, Mukesh Dodwadiya and SS Bhati
An integrated trial was carried out for the management of Heterodera zeae on sweet corn (variety- Madhuri). Bio-agent (Paecilomyces lilacinus, Pochonia chlamydosporia and Trichoderma viride at 2 % w/w as seed treatment) and botanicals (neem, karanj and lantana leaves powder at 2 g/plant as soil application) were used in combination for the management of maize cyst nematode, H. zeae on sweet corn. A trial was conducted in naturally infested soil having an initial nematode population of 600 larvae/100 cc soil. A standard chemical check (acephate 1 % as seed treatment + phorate 1 kg a.i./ha as soil application) and an untreated check were also maintained for comparison of the experimental findings. Observations on shoot weight (g), root weight (g), cyst per 100 cc soil, cyst per plant and final larvae per 100 cc soil, were recorded. Results exhibited that among bio-agent and botanical combinations, Paecilomyces lilacinus at 2% w/w coupled with neem leaves powder at 2 g/plant was found most effective for the management of maize cyst nematode followed by Pochonia chlamydosporia + neem leaves powder and Paecilomyces lilacinus + karanjleaves powder.
