What is one significant advantage of disease-resistant greenhouse cultivars?

One significant advantage of disease-resistant greenhouse cultivars is that they reduce the need for chemical pesticides. This is important because lower reliance on pesticides leads to a healthier growing environment for both plants and beneficial insects. Additionally, it minimizes the risk of chemical residue on crops, making them safer for consumers.

By adopting disease-resistant varieties, growers can mitigate the potential spread of diseases within their crops, which not only enhances plant health but also increases overall yield. This sustainable approach contributes to better environmental practices, lowers production costs associated with pest management, and aligns with consumer preferences for organic and environmentally friendly products.

The other options do not align with the benefits of disease-resistant cultivars, as they typically do not require more water, may not be more expensive to produce, and are often bred to maintain or improve growth rates and yields.
