Study on the resistance inducing chemicals against the Alternaria blight disease in linseed in in vivo

Author(s): Bhagyashree Singh, RB Singh and Prashant Kumar Singh

Abstract: Linseed is one of the major Rabi oilseed crop of India. It is grown in Madhya Pradesh, Uttar Pradesh, Maharashtra, Jharkhand, Chhattisgarh and Bihar. In the country Madhya Pradesh and Uttar Pradesh together contribute to the national linseed production to the extent of about 70%. It is one of the oldest crops cultivated for seed and fiber. Among the various factors responsible for lowering down its yield Alternaria blight caused by Alternaria lini is considered to be the major one. The efforts were made to search efficacious and cheaper resistance inducing chemicals as compare to fungicide under field condition for the management of the disease. Field experiments were conducted at the University Experiment Station at Kumarganj (Faizabad) Uttar Pradesh during rabi 2011-12 & 2012-13 seasons following recommended agronomic practices including nutrient management i.e. 80Kg N, 40Kg P, 40Kg/ha. The cultivar ‘Shekhar’ was sown on 25 October in randomized block design having 4m x 3m plot size with 30x10 cm plant spacing in three replications. The effectiveness of different resistance inducing chemicals viz. Benzoic acid, Napthelic acetic acid, Salicylic acid, Phosphoric acid, Isnicotinic acid at 0.05 and 0.1% concentration along with fungicide Mancozeb @ 0.25% were tested against the disease severity and seed yield of the crop Minimum disease (28.40%) severity with maximum yield T10 (724.16kg/ha) was recorded with spraying of Salicylic acid @ 0.10% followed by the same chemical @0.05% and Benzoic acid @ 0.10% respectively. But maximum benefit cost ratio was recorded with Benzoic acid @ 0.05%.
