Disease - Anthracnose
Causal organism - Colletotrichum capsici
Symptoms - This disease can occur on leaves, stems and both pre & post-harvest fruit. Due to this disease, small black spots appeared on the leaves and the leaves start falling.
When its effect becomes more, the branches start to dry from top to bottom. Symptoms of this disease also seen on the ripe fruits.
Infected transplant is also a reason to introduce anthracnose disease in the chilli field.
Warm & wet weather favours the development of this disease.
High temperature approx. 28°c, high relative humidity approx. 92 % and above also favours in the development of this disease.
Damage - Severe infection by anthracnose disease may causes yield losses of up to 50 %. Presence of blemishes on fruits reduces the marketability of the crop.
It mainly affects mature fruits & causing severe losses due to fruit decay. Highly infected fruit turn in straw colour from their normal colour.
Control - To prevent this, mencozeb 2 grams should be dissolved in per litre of water and sprayed 2-3 times at an interval of 15 days.
Integrated Disease Management - Disease-free chilli seed should be planted. The field should have good drainage & be free from infected debris.
