Bacterial leaf blight (also called bacterial canker) can cause considerable damage in tomato plants. These bacteria can be transferred in seeds, young plants, fruit, water and during work on the plant. The bacteria can also survive in soil and substrate.

Bacterial leaf blight in tomatoes is best treated by switching on the plant’s natural immune response. To do this, add SalicylPure to the B fertilizer feeder. We also recommend administering Argentum via LVM.

A good but more labour intensive alternative is to spray Algicin® or Argicin®Plus.

Laboratory tests run by Groen Agro Control show that it is possible to reduce incidences of Clavibacter by more than 99% using this method. We are pleased to advise parties who wish to make use of this expertise in practise.
