Quizplus · Accepted Answer

The continuous evolution of pests and pathogens is undermining the development of disease-resistant varieties of plants. As pests and pathogens continue to evolve, they develop new ways to overcome the resistance of the plants, making it difficult to develop lasting disease resistance. Other factors such as monocropping and excessive pesticide use can also contribute, but the continuous evolution of pests and pathogens is the primary factor.
