Why are nematode-resistant plants considered cost-effective?

Nematode-resistant plants are considered cost-effective primarily because they help manage pest nematodes effectively. This resistance significantly reduces the economic burden associated with nematode damage in crops. By naturally repelling or tolerating these pests, such plants can enhance yields and reduce the need for costly pest management strategies, such as frequent pesticide applications or extensive soil treatments.

The approach of utilizing resistant varieties means less reliance on chemical control measures, which can be expensive and labor-intensive. Additionally, healthier plants that can withstand nematode pressures are more likely to produce better-quality yields, further contributing to overall savings and profitability for growers.

While other factors such as water requirements or growth rates can influence costs, these are not the main reasons for the economic advantage provided by nematode-resistant plants. The key aspect is their ability to reduce nematode populations effectively, making them a practical choice for sustainable agricultural practices.
