Question

Tikka is a :
A. Fungal disease
B. Viral diseases
C. Bacterial disease
D. Protozoan disease

Answer 1

Hint: All portions of the host plant above soil are attacked by way of means of this disorder. The first seen signs and symptoms of tikka disorder seem at the leaflets of decreased leaves as darkish spots which at a later stage, are surrounded by means of yellow rings.

Complete answer:
To answer this question, first, we need to know about the causative organism of Tikka disease. The groundnut leaf spots (early leaf spot and over due leaf spot) are usually known as. “Tikka” disorder causes almost whole defoliation and yields loss as much as fifty per cent or extra relying upon disorder severity. The leaf spot sickness epidemics are tormented by climate parameters inclusive of warm and moist conditions. The causal organism of tikka sickness is the organism of the Cercospora genus specifically Cercospora personata and Cercospora arachidicola. According to the survey, tikka sickness can cause epidemics in all groundnut developing countries, inclusive of the United States, China, India, etc.
Now, let us find the solution from the option.
Tikka Disease is a usual disorder in groundnut as a result of Cercospora arachidicola and Cercospora personata. In the diseased condition, many circular spots seem at the outer layer of the leaf. The conidia of the fungus found in soil or the ones located inside the fruit shell is the supply of infection.
 It is not as a result of virus, micro organism and protozoa.

Hence, the correct answer is option (A)

Note: The tikka disorder is a fungal disorder that is particularly as a result of fungus Cercospora personata as pointed out above that belongs to magnificence Deuteromycetes. The signs and symptoms consist of lesions at the leaves. These lesions are observed on each of the perimeters of the leaf. Practices like crop rotation may be useful in preventing the disorder. The use of phosphatic and potassic manures lessen the disorder. Sulphur dusting is pretty effective.
