Item Coconut root (wilt) disease in Trichur district 2: Observations on disease recurrence(2007-02-08) Kochu Babu, M.; Radha, K.; Rethinam, P.; Antony, K.J.Four hundred coconut root [wilt] affected palms distributed in eight villages north of Karuva-nnur river in Trichur district Kerala were eradicated to prevent the spread of the disease further north. Observations on disease recurrence in the affected gardens were recorded periodically. Out of 209 gardens from where 400 root [wilt] disease affected palms were eradicated 193 gardens [92.4%] remained free of disease after four years. The gardens with disease recurrence are located in low lying areas of hill slopes and riverbed. Eradication is more effective in gardens where initial incidence of disease was low. Young palms are more susceptible to the disease. Within the diseased gardens spread of the disease was erratic.Item Coconut root (wilt) disease in Trichur district- Observations on disease recurrence(1985-08) Kochu Babu, M.; Radha, K.; Rethinam, P.; Antony, K.J.Four hundred coconut root [wilt] affected palms distributed in eight villages north of Karuvannur river in Trichur district Kerala were eradicated to prevent the spread of the disease further north.

In the absence of a definite chemical control measure, a two-pronged approach was made namely to live with the disease in the heavily infested areas of southern Kerala and contain the disease in the mildly affected areas of northern Kerala and border districts of Tamil Nadu adjoining Kerala. Integrated management increased nut yield from 28 to 51 nuts/palm/year within three years in mildly affected area and 23.4 nuts/palm/ycar on an average in disease affected area. Irrigation coupled with fertilizer application, plant protection measures and mixed cropping increased the yield of disease affected coconut garden from 17.6 to 46.0 nuts/palm/year. In the mildly infected areas, the removal of disease affected palms irrespective of yield, continuous monitoring and removal helped to maintain almost disease free condition.Item Stem Bleeding Disease Of Coconut(1976) Ramanandan, P.L.; Antony, K.J.
