Pythium and Rhizoctonia
called damping-off, Pythium primarily attacks the jasmines roots, while
Rhizoctonia can infect all parts of the plant. These fungal infections are
spread and most active in wet, humid conditions. Poor soil drainage, limited
air circulation, heavy rainfall or overhead irrigation may all contribute to
root-rot diseases. Infected roots soften and darken, and new shoots on the
plant may grow in distorted or turn brown and lifeless. Plants experience slow
growth, decline and may eventually die.
Improve soil drainage as necessary.
Temporarily remove soil at the base of the plant to allow the roots to dry;
replace with dry, sterilized soil. Prune to remove infected foliage and to
improve air circulation. Destroy cuttings away from the garden. A fungicide
drench may help prevent the spread of the disease, but may not cure it. Choose a
fungicide labelled effective against Pythium or Rhizoctonia and follow label
