Question

The growth of weeds can be controlled by

• A. Manual removal
• B. Irrigation
• C. Herbicides
• D. All of the above

Answer 1

Answer: (D)

All of the above

The growth of weeds can be controlled by the following methods:

(1) Coverings: In domestic gardens, methods of weed control include covering an area of ground with a material that creates a hostile environment for weed growth, known as a weed mat. Several layers of wet newspaper prevent light from reaching plants beneath, which kills them.
(2) Manual removal: Many gardeners still remove weeds by manually pulling them out of the ground, making sure to include the roots that would otherwise allow them to resprout.
(3) Irrigation: Drip irrigation involves bringing water directly to the roots of the desired plants, thereby limits weed's access to water.

(4) Biological pesticide: Vinegar kills the visible part of the weed. They will wrinkle and die the next day, although the root will still be in place to continue growing.

Therefore, the correct answer is option D.
