On the surface of the bark of coniferous trees, a coating in the form of rust can form, which is caused by a parasitic fungus. Over time, rust of coniferous trees leads to gradual drying out. This contaminates neighboring pines.
How does rust develop on conifers
Spores of the parasite fungus gradually penetrate the needles. Young seedlings are more susceptible to rust formation. At the first stage of infection, the needles turn pale. In later stages, the color changes to a brown or bright orange, reminiscent of true rust.
Rust cancer is the name given to this disease of pine trees. During the intensive stage of the disease, external defects can form on the pine - tissue overgrowth, etc. Both black and cedar Siberian pines can suffer from rust. To prevent the formation of rust, it is advisable to carry out preventive treatment with special agents.
