象牙海岸种植菠萝要度过两个易感心腐病的时期:一个是幼苗定植期间;另一个是用电石诱导开花后的一个时期。因此,为了防止植株感心腐病,到目前为止,人们还是沿用液体杀菌剂浸苗定植,植后3—4星期再喷一次药。弗罗萨1976年指出,用电石诱导开花后,接着喷施一次液体杀菌剂,这样能保护部分菠萝免遭病害的侵袭。作为商业规模使用的杀菌剂,以有效成分0.4％的敌菌丹为佳。
The planting of pineapples in the Ivory Coast is going through two stages of susceptible heart rot: one during seedling colonization and the other after the flowering with calcium carbide. Therefore, in order to prevent the plants feel rotten, so far, people still follow the liquid fungicide soaked seedling planting, 3-4 weeks after planting spray another drug. Frosa in 1976 pointed out that the use of calcium carbide to induce flowering, followed by spraying a liquid fungicide, which can protect some pineapple from disease invasion. As a fungicide used on a commercial scale, it is preferable to use dactinomycin which is 0.4% of active ingredient.
