Which cultural practice can help prevent plant diseases?

Planting disease-resistant varieties is a crucial cultural practice for disease prevention in plants. By selecting and cultivating varieties of plants that have been specifically bred or selected for their resistance to certain diseases, growers can significantly reduce the likelihood of infection and spread of pathogens. This practice not only minimizes the need for chemical interventions, but it also helps sustain healthier crops, ultimately leading to better yields and reduced economic losses.

In contrast, relying solely on chemical treatments can lead to resistance development in pathogens, while over-fertilization can contribute to nutrient imbalances and stress plants, potentially making them more susceptible to diseases. Neglecting land preparation can result in poor soil conditions and unhealthy plants, which can directly increase vulnerability to disease outbreaks. Thus, planting disease-resistant varieties stands out as a proactive, preventive strategy in managing plant health.
