| dc.description.abstract | The wilt disease complex ofcocoa was first noticed in India in 1998. in Karnataka. The leaves became yellow or brown, branches wilted and finally the plant died. Pods of the affected trees did not show any external symptoms, but shrivelled slowly leading to the death of the trees. The affected plants were consistently associated with Xylosandrus beetles which inhabited short pin hole borings made by them. Several fungi were found associated with the disease of which Ceratocystis sp.? was found to be consistently present. Pathogenicity trials with inoculation of Ceratocystis sp.? by wound inoculation-cotton plugging method produced internal symptoms of wilt in the seedlings. Field trials with systemic chemicals showed that the diseased plants recovered when Propiconazole @ 0.2 %, and Imidacloprid @ 0.2 % were used simultaneously as whole plant drenching. The incidence of fresh infection was Jess when compared with the other treatments. | en_US |
