Exocortis virus was readily transmitted by contaminated knife blades and fingers. Mechanical transmission by knife cuts was prevented by a 1-second dip of the contaminated blades in diluted household bleach or a solution of 2% sodium hydroxide plus 2% formalin. Heating contaminated blades for 4 to 6 seconds in the flame of a propane torch or flaming blades dipped in 95% alcohol failed to inactivate the virus. A 1-second dip in the following chemical suspensions or solutions also failed to prevent transmission: 20% phisohex, 3% formalin, 2% trisodium phosphate cleaner, 10% borax, 1% lysol and 95% ethyl alcohol. a 20% household bleach solution (containing about 1% sodium hypocrlorite) is recommended as a disinfectant for pruning and grafting tool. The corrosive action of the bleach on tools was avoided by dipping in a mixture of vibegar, water, and emulsifiable oil. Mild isolates of exocortis virus were separated from severe isolates by knife transmission. |
