The most common cactus malady is mold, usually caused by overwatering. If mold is detected on a cactus, the affected part should be cut off as soon as possible, using a sharp knife. Then the wound should be sprinkled with sulphur or a fungicide. If the roots are affected, the core of the cacti is probably also affected and the plant will almost certainly die.
The only pests that bother cacti are a type of scale insect of the family Coccoidea, and nematodes. Scale insects may be killed by squirting the plant with a mixture of rubbing alcohol and nicotine. If nematodes are detected, the roots of the cactus must be cut off with a sharp knife and the plant repotted in sterile soil until it grows new roots. The old soil should be sterilized and the removed roots should be burned.
