That scenario is caused by “reassortment,” the exchange of genetic material when hosts are infected with multiple versions of a virus. The U.S. Agriculture Department’s Animal and Plant ...

The active ingredients have a broad spectrum effect; a series of RNA molecules support the plant's immune system in combating the virus. In laboratory experiments, 80 to 100% of the treated plants ...
