Leaf symptoms can be varied but typically consist of angular, yellow areas between the veins. The plants may still crop reasonably at first. The most common problem is raspberry mosaic disease, caused by a combination of viruses spread by aphids. Another factor that suggests a virus infection is when some varieties are affected more than others.Ī All cane fruit can be affected, but raspberries are particularly susceptible. It is more likely to be a virus if the plants are also stunted or are distorted, and if the crop is very poor. It is more likely to be a deficiency if all the plants are affected, regardless of variety, or if the problem occurs within the first year or two of planting. How can I tell them apart?Ī Leaves suffering from iron or magnesium deficiency can look like those with a virus infection. ![]() Q This symptom virus on raspberry sounds very similar to mineral deficiency. ![]() The leaves become mottled, with yellow patches between the veins.Ĭaption: Virus stunts or distorts the plants and reduces the crop Q How do I recognise virus infection on raspberries?Ī Initially the symptoms can be very subtle – a gradual decline in the crop, perhaps a little stunting, distortion or discolouration.Īs the disease builds up, the symptoms become pronounced and crop production may suffer.
