Question

Quizplus · Accepted Answer

Planting large areas with a single variety, also known as monoculture, encourages the rapid spread of plant diseases because such a practice eliminates genetic diversity which serves as a natural defense against pests and diseases that can attack crops. Hence, if one plant is infected, the disease can spread quickly throughout the rest of the monoculture, leading to significant losses.
