Partial Control of Bacterial Wilt of Tomato with Chinese Chives

Edward Berkelaar, Ph.D.

We recently learned of a simple technique that may reduce bacterial wilt in tomatoes. Interplanting (or pre-planting) Chinese chive with tomato results in allelopathic suppression of the organism responsible for bacterial wilt.

Bacterial wilt is a disease that affects many different crops, including tomato, potato, tobacco, pepper, the curcurbits (cucumber, cantaloupes, squash, and pumpkins) and some forage crops. The disease is caused by a number of different bacterial organisms. In tomato, the disease is caused

A habitat management system to control stemborers and striga has been developed by the International Centre of Insect Physiology and Ecology (ICIPE), along with Kenya’s Ministry of Agriculture, the Kenya Agricultural Research Institute (KARI), and IACR-Rothamsted of the UK. The system is called a ‘push-pull’ strategy.
