Kabatina Tip Bligh
COMMENTS on disease
Tip blights cause the tips of cedar branches to die. Often,
small black dots, fruiting structures of the fungi that cause tip blights, are
visible on the affected needles. Junipers are particularly susceptible to Phomopsis and Kabatina tip
blight, two damaging fungal diseases that cause needle browning and dieback at the tip of the branches. Tip blight
of junipers is caused by two different species of fungi, Phomopsis juniperovora and Kabatina juniperi, which
cause similar symptoms in the affected plants. However, the two diseases differ
by the time of the year when they occur and their development on the plant.
blight can be particularly devastating in nursery settings when it affects
seedlings of young grafted stocks. Otherwise, the damage it causes on junipers
in natural or landscape settings is not very significant.
are more prevalent in moist and warm conditions. Whenever possible, resistant
varieties should be planted to prevent these diseases, and healthy practices
implemented. These include adequate spacing between plants to allow for
sufficient air flow, avoiding prolonged night time watering or using overhead
sprinklers, and pruning and discarding any diseased material. Plants are
particularly susceptible to tip blight infection when stressed or wounded by
insects or mechanical injury.
