. . . nothing conclusive
Gee . . . How can we kill this STUFF?!
Multiflora stands = Reservoirs for RRD
Phil transmits RRD when he bites the rose.
Symptoms of the disease appear from the point of infection to the new growth of that branch.
Free water retreats to the larger canes and is bound in the cells in the fall . . .
. . . the infection travels with it. ***** (see the notes for this slide)*****
Next spring, the plant will show symptoms in all new growth.
2. Dig up bush and garbage bag it, DON’T COMPOST
3. Carefully remove remaining roots
4. Maybe spray surrounding bushes
5. Cut off infected cane from bud union ***
*** Only effective in early detection. Not recommended.
The “hypothesis” I am investigating currently is whether the mode of action of RRD is similar to that of 2,4-D.
