An experiment was conducted to find out the effect of some organic foliar treatments to manage the alternaria leaf blight disease in broccoli (cv. Green Sprouting) was studied under natural field condition in the field Laboratory of Plant Pathology Department, Bangladesh Agricultural University, Mymensingh during the period from November 2005 to March 2006. The integrated management options were placed in Completely Randomized Block Design with three replications. The treatments were control (no spray), field sanitation, Neem extract, Mahogany extract, Koromcha (Carissa carandas) extract, Garlic extract (Allium sativum), Neem+Mahogany+Koromcha (Carissa carandas) extract, Garlic+Neem+Koromcha (Carissa carandas) extract, Rovral 50 WP @ 0.2% which was used as a positive control. Besides field sanitation, aqueous extracts of Neem, Mahogany (Swietania mahagoni), Koromcha (Carissa carandas) and garlic clove (Allium sativum) administered as foliar spray, singly or in combination were studied for efficacy and profitability compared to control treatment and spray with Rovral 50 WP. All the treatments controlled the alternaria blight disease of broccoli significantly giving higher yield compared to control. Though spraying with Rovral gave the best result both in terms of disease control and yield of broccoli, the combined application of Garlic (Allium sativum), Neem and Koromcha (Carissa carandas) extracts  performed as good as Rovral. Rather this organic combination gave a higher BCR (4.74) due to reduced production cost indicating that judicious combination of organic management practice promises a healthy broccoli production which is environment friendly, healthy and profitable.
