Consider the following statements and select the correct answer from the codes given below:
Assertion (A): The production of rubber is decreasing in the Amazon.
Reason (R): Equatorial climate is favourable for rubber plantation.
Cultivation of rubber in Brazil, its native habitat, was severely hindered by blight in the early 20th century.
At present, most of the world’s natural rubber is produced by Rubber trees descended from rubber seedlings transplanted from South America to the south and south-east Asia.
The most severe disease is the South American Leaf Blight (SALB).
This Disease is endemic throughout the rubber growing areas in the Americas. It also poses a major global threat.
Several fungicides can control the fungus. Some Species are not susceptible to the disease, and some strains of susceptible species are resistant.
Crown budding or grafting of resistant plants onto productive trees can be used to control spread.
