Red-rot and Ergot diseases are fungal diseases that affect certain crops.

Red-rot is a disease that primarily affects sugarcane crops. It is caused by a fungus called Colletotrichum falcatum. This fungus attacks the roots and stalks of the sugarcane plant, causing rotting and decay. The infected plants show symptoms such as red discoloration of the affected tissues, stunting of growth, and poor yield. Red-rot can significantly affect the productivity of sugarcane crops.

On the other hand, Ergot is a fungal disease that affects mainly grains, particularly wheat and barley. The fungus responsible for Ergot is Claviceps purpurea. It infects the ovaries of the plants, replacing the kernels with fungal structures called sclerotia. These structures are dark in color and contain toxic alkaloids. Consumption of grains contaminated with Ergot can lead to various health problems in humans and animals, including hallucinations, gangrene, and convulsions.

Therefore, the correct answer is option 4: Sugarcane and Bajra are associated with red-rot and ergot diseases, respectively.
