Abstract

ABSTRACT:
Brown spot of paddy (Helminthosporium oryzae) is prevalent in all rice growing areas of the country especially in heavy monsoon areas of West Bengal. The indiscriminate use of chemical fungicides to control the disease is not only hazardous to living beings but also adversely affects the environment. Successful control of the diseases by different tree biomass and by using bio control agents which had no adverse effect on the environment is one of the challenging objectives in organic farming. The present research work has been carried out at Bidhan Chandra Krishi Viswavidyalaya, “C” block farm, Kalyani, Nadia, West Bengal, during Kharif 2013 with the objective to assess the effect of different organic nutrient and plant protection management practices to control the brown spot disease in rice crop. The results revealed that combination of Seed treatment with Brahmastra + Foliar spray with Brahmastra and seed treatment with Brahmastra + Trichoderma harzianum soil application @ 130 kg ha-1 was recorded significantly lower brown spot disease intensity with organic nutrient management levels of vermi compost @ 30 kg N ha-1 + Mustard cake @ 30 kg N ha-1 as compared to the control and it was observed that it reduces approximately 10 – 19 % disease intensity as compared to control.
