Solution Management of fruit and vine rot of pointed gourd
Country India
Last update: 08/10/2006
Challenge/Issue Drying of vine is found in new planted crop during April - may following a heavy or light shower. Farmers popularly call it as dry or Sukno Haja. A few fruits have been found to be affected. Infection usually starts at the middle portion of the fruits which shrinks and dries up. If there is cloudy weather or rain or soil remains moist due to application of irrigation white mycellial growth develops in the infected portion.After starting of monsoon frequent rains and cloudy weather favours the spread of the disease, more and more vines and fruits get affected. Affected tissues become water soaked and discoloured. In all cases the affected area of the fruits is covered with white mycellial growth. During this phase stem infection is also found mainly in the nodal region. During rainy days oozing of sticky substances from diseased stem, leaf and fruit tissues are quite common which usually takes places before formation of mycellial growth.
Method Strict sanitary measures i.e. removal of diseased fruits and vines should be followed.

Proper scheduling of irrigation and good drainage facility should be ensured.

Straw mulching checks the spread of the disease to some extent.

Cultivation of pointed gourd on scaffold should be done.

Alternate spraying of metalaxyl + mancozeb @ 2.5g /l of water and copper oxy chloride @ 4g /l of water effectively checks the disease.

Spraying of fungicides just before sunset give good result.
Lessons learned Heavy shower after a hot dry spell, continues rainy days, stagnation of water in the field, poor sanitary condition has been identified as favourable condition for disease severity.

Crops grown on soil bed and ratoon crop suffered more as compared to crop raised on scaffold and newly planted crop.
