Can agricultural plastic covers reduce crop damage from pests and diseases?

Yes, agricultural plastic covers can significantly reduce crop damage from pests and diseases. These covers, often referred to as protective barriers, create a physical barrier that prevents pests from reaching the crops and diseases from spreading. They also help in maintaining a controlled environment, which can reduce the need for chemical pesticides, thereby minimizing the risk of disease transmission. Additionally, plastic covers can protect crops from environmental stressors, such as extreme temperatures and heavy rainfall, which can also lead to diseases. However, it's important to manage these covers properly to avoid issues like excessive humidity that might foster the growth of certain diseases.
