Solution(By Examveda Team)
Calaxin is the most recently widely used fungicide for the control of powdery mildew.Powdery mildew is a fungal disease that affects a wide range of plants. Powdery Mildew (Acrosporium tingitaninum) is a Whitish powdery mass that develops on the young leaves and twigs. Affected leaves get distorted.
Powdery mildew can be controlled easily by spraying Wettable Sulphur (1.5 kg/200 litres of water). Sulphur dusting (20 kg/hectare) in the morning hours controls the disease effectively. Systemic fungicides like Bayleton (1 g/litre of water) or Calaxin (3 - 4 ml/10 litres of water) or Benomyl (5 g/10 litres of water) offer better and prolonged control of the disease.
