Question

What are the necessary characteristics of a weedicide?

• A. They should be able to kill weeds
• B. They should not affect crops
• C. Necessarily both A and B
• D. They should be toxic to humans

Answer 1

The correct option is C Necessarily both A and B

Weedicides are chemicals that are used to kill weeds. It is also necessary that they should not affect the crops during weeding. It would be an optimal characteristic that weedicides are non-toxic to humans but most of the time, having an ideal combination of all the three characteristics is difficult. Since killing weeds while not affect crops, it is the most desirable outcome of a typical weedicide. It is usually toxic to humans making it necessary to use protective measures while using weedicides.
