Some pests that commonly affect pineapple plants are scales, [[thrip]]s, mites, mealybugs, ants, and [[symphylid]]s.<ref name="foodmarketexchange1" />

Heart-rot is the most serious disease affecting pineapple plants. The disease is caused by ''[[Phytophthora cinnamomi]]'' and ''[[Phytophthora parasitica|P. parasitica]]'', fungi that often affect pineapples grown in wet conditions. Since it is difficult to treat, it is advisable to guard against infection by planting resistant cultivars where these are available; all [[Suckers (botany)|suckers]] that are required for propagation should be dipped in a fungicide, since the fungus enters through the wounds.<ref>{{Cite book|title=Encyclopedia of Gardening|last=Brickell|first=Christopher|publisher=Dorling Kindersley |year=1996|isbn=978-1-85833-579-7|location=London |pages=419}}</ref>
