Question

Which of the following is not a method by which pathogens affect the yield of crops?

(a) Reduce the quantity of yield

(b) Reduce the quality of crop produce

(c) Increase in cost production

(d) Increase the flowering period

I got this question in an internship interview.

This question is from Plant Diseases and their Control topic in section Strategies for Enhancement in Food Production of Biology – Class 12

Answer 1

The correct choice is (d) Increase the flowering period

To explain: Pathogens affect the crop yield by reducing the quantity of yield and reducing the quality of crop produce. Pathogens also increase the production cost due to reduced yield and expenditure on pesticides.
