The larvae are slimy in appearance, and are sometimes referred to as "slugs" (e.g., the "pear slug") although they are insects rather than gastropods. The larvae of some species in this genus are important pests which can do significant damage to the leaves of trees such as oaks, poplars, and cherry and pear trees.
Molluscicides (/ m ə ˈ l ʌ s k ɪ ˌ s aɪ d s,-ˈ l ʌ s-/) [1] [2] – also known as snail baits, snail pellets, or slug pellets – are pesticides against molluscs, which are usually used in agriculture or gardening, in order to control gastropod pests specifically slugs and snails which damage crops or other valued plants by feeding on them.
Like many rusts, G. sabinae requires two different hosts to complete its life cycle from year to year. Juniper is the winter host and pear is the summer host. Spores (called aeciospores) are produced from the fungal lantern-shaped growths which protrude from the blisters on the underside of the pear leaf which become airborne and infect junipers.
The apple skin remains shiny and unbroken, and shrinkage of the actual tissue does not occur until later in development, where it often rots quickly in storage. Fruit rot is commonly found on apples, pears, and plums, but is less often found within peaches, nectarines, or apricots. [5]

Included in this genus are multiple species of trees and shrubs, such as: Dibotryon morbosum infects are Prunus serotina (wild cherry trees), Prunus persica (peach trees), Prunus domestica (plum trees), and Prunus cerasus (sour cherry trees). [3] The main symptom of Dibotryon morbosum is its “knot-like” gall structure. These knots can vary ...
