Is this a Minor Pest?
Yes
Minor Pest Title
Fusarium wilt (<i>Fusarium oxysporum </i>f.sp. <i>passiflorae</i>)
Minor Pest Description
Fusarium wilt (also called collar rot) symptoms consist of yellowing of leaves, the collar region of affected plant at soil level turns brownish and vertically cracks and vines wilt followed by a complete collapse of the plant. On dissection of infected stem, vascular tissues show brown discolouration.
Minor Pest What to do.
- Affected parts should be removed and burned. Snap off the affected parts or remove the affected plant manually.
- Do not cut tissue and then use the knife on healthy plants.
- Keep the base of the plant clear of grass and weeds, which favour fungal growth.
- Grafting to wilt-resistant yellow passion fruit rootstocks (e.g. P. caerula) is the most practical way of control.
