These bacteria cause, for example, head rot in broccoli and bacterial canker in cherry and plum.
Spray with Cuprum:
- fruit trees: in the autumn when they lose their leaves and in the spring when in bloom
- broccoli: twice before the umbrel closes and twice more, at an interval of seven days between each application.
Drip feed SalicylPure if possible to directly activate the plant’s own defence system.
