The influence of two pre and post-planting fungicides on the growth and fruiting of MD2 pineapple (Ananas comosus .L. (Merr)

摘要

The effects of two fungicides (Contizeb and Suncozeb) applied at both pre and post planting stages, against heart and root rot, were investigated on MD2 pineapple. Contizeb recovered more suckers than either the control (untreated suckers) or the Suncozeb-treated suckers. It significantly (contizeb) produced more fruits than the control. However the Suncozeb solution yielded the heaviest, lengthiest and the widest fruits amongst the three treatments. It could thus be more useful to apply the Contizeb in the early stages of the suckers and follow it up with the Suncozeb.
