When the crown is cut, internal [...] internal symptoms can be seen, such as discolouration of vascular and cortex tissue (outer tissue layer) to orange-brown to dark brown. Cutting the roots may [...] conditions for this fungus are temperatures above 32 °C and dry conditions. In field crops in temperate regions it is therefore not a problem. How to prevent

Viruses can be transmitted from one plant to another. Both T. vaporariorum and B. tabaci are known to transmit viruses [...] greenhouse and field crops, feeding on plant sap and transmitting harmful viruses. Their feeding weakens plants, causes leaf yellowing and leads to honeydew

The most direct damage is caused by the larvae mining the leaf tissue, leading to desiccation, premature leaf-fall and cosmetic [...] cosmetic damage. In tropical and subtropical areas this can lead to burning in fruit such as tomato and melon. Loss of leaves also reduces yield. In full-grown
