I've recently noticed some damage on a couple of the leaves of my Masdevallia decumana. I suspected that the damage was caused by tiny snails, but I removed the leaves as a precaution, in case there was a tiny pest present that I hadn't seen. Today I removed this Masdevallia decumana flower, as I noticed damage to the flower. Pictured on the 16th October 2016.
Here you can see a more considerable covering of powdery mildew on the Lathyrus odoratus plants. Though, looking on the bright side, these Lathyrus odoratus tendrils have formed a beautiful heart shape. Pictured during my 2016 Sweet Pea Trial.
This photograph was taken on the 18th June 2016. Here you can see that powdery mildew has begun to establish itself on the Lathyrus odoratus plants. This is Lathyrus odoratus 'Ida King' which has been grown as a cordon, this was the first plant to become susceptible to powdery mildew in the 2016 Sweet Pea trial.
A closer look at an aphid colony present on the underside of an Lathyrus odoratus leaf. The white objects in the picture are the shed skins of the aphids, and the brown insects of varying sizes are lacewing larvae at differing stages of development.
Aphids often colonise the undersides of plant leaves where they are less visible to predators. In this photograph, you can see a number of lacewing larvae predating on an aphid colony gathered on the underside of a Lathyrus odoratus leaf.
