Flax (Linum usitatissimum L.) is a food, fiber and oil seed crop cultivated in cooler regions. The oil content of the seed varies from 33–47%. In India it is grown mainly for seed used for extracting oil. The crop is affected by Alternaria blight caused by Alternaria spp. Different doses of microalgae were applied (@ 1.5, 2.5, 3.5, 4.5, 5.5 and 6.5 kg/acre) with irrigation at critical growth stages of crop (vegetative phase, flowering phase and maturity phase) and observations were recorded on plant growth parameters and per cent disease incidence of Alternaria Blight. Results revealed that, in field the application of microalgae i.e., 6.5kg/acre recorded minimum per cent disease incidence (23.08%) which was significant over other treatments and control (45.2%). Thus, the use of microalgae against Alternaria blight significantly reduced the per cent disease incidence and use of microalgae can be exploited for the management of blight diseases of flax.
