Question

Which of the following characteristics protect maize plant from the stem borers?
A. High aspartic acid
B. Low nitrogen content
C. High sugar content

• A. A only
• B. A and B only
• C. A, B and C
• D. A and C only

Answer 1

The correct option is B A and B only

Agricultural pests are organisms that attack agricultural crops and destroy them, leading to huge crop losses. Some crop plants naturally develop resistance to pests as a result of morphological, physiological or biochemical characteristics in them.

In maize crop certain biochemical characteristics like low nitrogen, low sugar and high aspartic acid content helps resist against maize stem borers (insect larvae which bore into plant stems).

Hence, option b is correct.
