Plants that are infected must be destroyed as the disease can be transmitted from plant to plant by contaminated sap. Symptoms include dark green ink bleed marks in the veins of yellow-colored leaves, and/or tissue collapse between veins.
Exposure to EMF and cancer. Magnetic fields are classified by the International Agency for Research on Cancer (IARC) as a possible cause of cancer, particularly for childhood leukemia. However, experts agree that there may be other explanations for the potential link between exposure to EMF and childhood leukemia. Until scientific evidence can clarify the link between exposure to magnetic fields from high-voltage power lines and cancer risk, you may not want your children to play directly beneath them for long periods of time.
Four large studies looked at the effects of ELF magnetic fields on cancer in rats and mice. These studies exposed the animals to magnetic fields much stronger than what people are normally exposed to at home, with fields ranging from 2 to 5000 microtesla (ÂµT).n this document, the term âmagnetic fieldâ is used to indicate ELF radiation from a magnetic field, while âelectrical fieldâ is used to mean ELF radiation from an electrical field. The possible link between electromagnetic fields and cancer has been a subject of controversy for several decades.
