Abstract

Four fungi, Botryodiplodia theobromae, Pestalotia palmarum, Phoma sp. and Thielaviopsis basicola-associated with seed coconuts were exposed to methyl bromide (MeBr) fumigation directly as well as after implanting them into seeds at different concentrations and exposure timings, critical to seed coconuts. The fumigation was carried out in air tight chambers at the Plant Quarantine and Fumigation Station, Cochin, and the fumigated cultures were transferred to fresh medium to study their viability. Observations on presence/absence of fresh growth on sub-culturing indicated that fumigation with MeBr at concentrations and exposure timings, critical for seed coconuts, is not sufficient to kill any of the four fungi.
