Foot rot

Foot rot caused by P.Capsici is the most destructive of all diseases and occurs mainly during the South-west Monsoon season. All parts of the wine are vulnerable to the disease and the expression of symptoms depend upon the site or the plant part part affected and the extent of damage.
Symptoms
1) One or more black spots appear on the leaves which have characteristic fine fimbriate margins which rapidly enlarge and cause defoliation.
2) The tender leaves and succulent shoot tips of freshly emerging runner shoots trailing on the soil turn black.
3)If the main stem at ground level or collar is damaged, the entire vine wilts followed by shedding of leaves and spikes with or without black spots. The branches break up at nodes and the entire vine collapses within a month.
