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.
Magnetic storms can pump extra electricity into our power lines and pipelines, causing blackouts and fuel leaks. In March 1989, a magnetic storm burned up a $36 million transformer in New Jersey and collapsed the entire power grid in Quebec, Canada, leaving six million people without electricity.
