Although easy to grow, tomato fruits can suffer from splitting and cracking in late summer. This is difficult to prevent, as it is caused by fluctuating temperatures and water supply - which are often out of the control of the gardener.

This is an example of a physiological disorder – a problem caused by the growing conditions rather than by a pest or disease agent. Inappropriate levels of water, light, temperature and nutrients can all cause a variety of physiological disorders in tomatoes. The fruits are especially vulnerable as they are at the growing tips and have to compete with the new shoots for water and nutrients.
As fruit splitting and cracking is a physiological rather than a pest or disease problem, there is no point in using pesticides to treat the problem. There are no chemical controls.
