Which is the best method of managing molya disease of wheat and barley?

✅Explanation:
Molya disease, caused by the cyst nematode Heterodera avenae, is a significant threat to wheat and barley crops. While resistant varieties like Raj MR-1 exist, crop rotation with non-host crops like chickpea is considered the most sustainable and environmentally friendly management strategy. Chickpea is not a host for the molya nematode, so rotating it with wheat or barley helps to break the nematode's life cycle and reduce its population in the soil.
