Which one is the wrong pairing for the disease and its causal organism...
Late blight is caused by the fungus Phy-tophthora infestans. Late blight appears on potato or tomato leaves as pale green, water-soaked spots, often beginning at leaftips or edges. The circular or irregular leaf lesions are often surrounded by a pale yellowishgreen border that merges with healthy tissue. Lesions enlarge rapidly and turn dark brown to purplish-black. During periods of high humidity and leaf wetness, a cottony, white mold growth is usually visible on lower leaf surfaces at the edges of lesions. In dry weather, infected leaf tissues quickly dry up and the white mold growth disappears. Infected areas on stems appear brown to black and entire veins may be killed in a short time when moist weather persists.

Which one is the wrong pairing for the disease and its causal organism...
Late blight of potato - Alternaria solani is the wrong pairing for the disease and its causal organism.
Explanation:
Late blight is a devastating disease that affects potato plants, caused by the oomycete pathogen Phytophthora infestans. It is one of the most destructive diseases of potato plants worldwide, capable of causing significant yield losses if not properly managed. Phytophthora infestans primarily affects the leaves, stems, and tubers of potato plants.
Alternaria solani, on the other hand, is the causal organism of early blight, which is a different disease that affects tomato plants. Early blight is caused by the fungus Alternaria solani and primarily affects the leaves and fruit of tomato plants. It can lead to defoliation, reduced yield, and decreased fruit quality.
Therefore, the pairing of late blight of potato with Alternaria solani is incorrect. Late blight is caused by Phytophthora infestans, not Alternaria solani.
In summary, the correct pairing for the disease and its causal organism are:
a) Black rust of wheat - Puccinia graminis
b) Loose smut of wheat - Ustilago nuda
c) Root-knot of vegetables - Meloidogyne sp
The incorrect pairing is:
d) Late blight of potato - Alternaria solani
