Farmers protect their crops from pests and diseases using agricultural plastic products in several ways. Mulch films are used to cover the soil, which helps in suppressing weeds and reducing the incidence of soil-borne diseases. Plastic tunnels and greenhouses create controlled environments that protect crops from external pests and adverse weather conditions. These structures also facilitate the use of integrated pest management systems, including the release of beneficial insects. Additionally, plastic nets and screens can be used to prevent direct contact between crops and pests, thus reducing the spread of diseases. The use of drip irrigation systems made from plastic can also reduce the spread of diseases by minimizing contact with soil and water-borne pathogens. These methods collectively help in maintaining crop health and increasing yield.
