In the north, the disease occurred upto Ala, Varan-darappally, and Kalloor of Trichur District. In the south, palms in Nemum, Ottassekharamangalam, and Maranelloor were infected. Earlier reports of-the disease were confined to gardens between Quilon and Vamanapuram in the south and Ochenthuruthy and Malayatoor in the north. Sporadic occurrence of this disease was also noticed in Kulasekharam and Vailom villages of Tamil Nadu. The spread was faster, more conspicuous, and rampant in sandy, sandy learn, and clayey soils and on the banks of rivers and canals. Intensity of disease was higher in sandy, sandy loam, and clayey soils than in laterite soils. Over 2-5 lakhs hectares of coconut plantations in Kerala are estimated to be affected by this disease.enArticle
