Diseases of jasmine: general information

Before proceeding with the description of what are the diseases of jasmine and the prevention from pest attacks, it is convenient to expose what are the characteristics of this specimen, in order to proceed with the correct practice of cultivation techniques. This plant is native to tropical and temperate climate regions, it is also called Jasminum and belongs to the Oleaceae family. It includes shrubby, climbing, deciduous and evergreen specimens. The flowers are very fragrant and develop towards the summer season. Jasmine is a partly rustic plant, according to the species it belongs to. It does not require specific care, it prefers a sunny environment, a temperate and warm climate, and the soil must be well drained and fertile.

Diseases of jasmine: powdery mildew, cochineal and aphids


Among the main diseases of jasmineit is essential to mention powdery mildew, aphids and cochineal. Powdery mildew, or sore white, can affect foliage, flowers and buds. The first phase of the attack consists of the discoloration of the infected area with a subsequent drying and finally a curling of the part. To prevent powdery mildew, just mix mature manure with the soil and treat it with sulfur. It is also necessary to thin the plant and use sulfur-based fungicides. Aphids are lice that attack the foliage, they treat themselves with pesticides that can be purchased at specialized shops. The cochineal is a parasite that reaches a maximum size of about 2 mm. It feeds on the sap present on the leaves and in the shoots, leading them to drying out, curling up and finally falling from the plant. If the infected area is limited, the cochineal can be eliminated manually using a swab soaked in water and alcohol. Alternatively, insecticides or white oil are used.

Diseases of jasmine: smoky gray and gray mold


Among other diseases of jasminethere are smoke and gray mold. The latter occurs when the climate is excessively humid, the temperatures are too high and the area is not ventilated enough. Usually, gray mold affects the young shoots and buds of the plant, developing a sort of light gray patina. The consequences of this fungus are the drying up and the fall of the infected parts of the plant. When jasmine is attacked by mold, a sulfur-based fungicide should be used, even if the best cure is prevention. On the other hand, smoking is not a real disease. It can be defined as a consequence of the presence of honeydew, a sugary substance produced by other parasites (aphids and cochineal). Over the time, the molasses tends to become hard and form very dark crusts that hinder the breathing of those areas of the plant. To eliminate and prevent smokiness, just prevent the parasites that produce the sugary substance from nesting on the aerial part of the jasmine.
