Tomato Problem In Coastal Areas.
In coastal areas, when High Humidity is present, Tomato crops finally dies after some sort of Tomato Leaf Curl problem.
I want to know
What this disease actually is called? What is its name?
If it is fungal problem or some viral attack caused by High Humidity or so?
Actually what happens is
30-40 days after transplants, leaves start to harden, then become liveless & curl upwards. During this period (at flowering stage) plant sets fruit but it doesn't reaches at normal fruit size & gets raddens as a tiny fruits. This problem stays around leaves & finally the plant growth stunted without marketable outputs.
Day time temperature at that time is 30-35C & night time temperature is 18/22C.
At that time there is a heavy dew fall & wind flows all the time.
Please help in this concern to diagnose the actual problem & what resistant varieties one should use....?
Thanks in advance.
