abstract
Coriander is an annual spice herb whose fresh and dried leaves; and seeds are used as food flavoring agents. The crop is prone to various pest and diseases, despite of the sowing season. The major pest of coriander namely three aphid species, Hyadaphis coriandri, Myzus persicae and Aphis carccivora results in 45 to 50 percent loss in yield, provided proper control measures are not taken. The powdery mildew of coriander, caused by Erysiphe polygoni, is the major disease that is as devastating as it could cause 50 per cent yield loss in absence of effective management. In order to scheme an integrated management strategy both controlling both the pest and disease, an experiment was taken up involving integrated application of biocontrol agent, fungicides and insecticides at different stage of crop growth. There were ten treatments, replicated thrice, involving the foliar application of biocontrol agent of Lecanicillium lecanii and pesticides namely Propiconozole, Carbendazim and Acetamiprid. This experiment was carried out at the Horticulture farm, College of Agriculture, Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh. Two foliar sprays of Lecanicillium lecanii 1.15WP (1×109 cfu/g) (40 g/10 L.) + spray of Propiconazole 25 EC @ 0.05% (10 ml/10 L) (first spray) + spray of Carbendazim @ 0.1% (second spray) resulted the lowest aphid population (5.59%). Similarly, it was found that the two foliar sprays of Lecanicillium lecanii + spray of Carbendazim (first spray) + spray of Propiconazole (second spray) was found to be superior over all the other treatment with lowest percent disease incidence (12.27%). The integrated use of biocontrol agents, fungicides and insecticides offer an effective management against the aphids and powdery mildew disease of coriander.
