My bajra heads have hard black spurs sticking out with sticky drops, what is this?

Hard dark spur like bodies replacing grains in the bajra head, often preceded by sticky sweet honeydew drops on the heads, are the signs of ergot, a fungal disease that infects the open flowers in humid weather around flowering time. This one matters for safety, because ergot bodies contain toxins and grain contaminated with them is not safe for people or animals to eat, so please confirm with a photo to your KVK or agri officer and do not mix this grain into food or feed. For handling the present crop, keep the ergot affected heads separate, and during cleaning remove the dark spurs as far as possible, but err on the side of caution about consumption and ask your officer about safe disposal of heavily affected grain. For prevention next season, use clean seed, grow tolerant hybrids where available, avoid late sowing that pushes flowering into very humid spells, and follow the seed treatment your officer recommends. Confirm both the safety steps and the prevention plan with your local KVK.
