Which approach is the best method to minimize virus transmission in plants?

• A. Water the plants more frequently
• B. Increase sunlight exposure
• C. Avoid wounding plants and reduce insect populations
• D. Use stronger pesticides

Answer: (C)

To minimize virus transmission in plants, the most effective method is to avoid wounding plants and reduce insect populations. Wounding can create entry points for viruses and increase the likelihood of infection. In addition, many plant viruses are spread by insect vectors, such as aphids and whiteflies. By keeping insect populations low through appropriate pest management strategies, the chance of virus transmission is significantly reduced. While watering plants more frequently could improve their overall health, it does not directly prevent virus transmission. Increasing sunlight exposure can enhance plant growth and resilience but does not directly address the transmission pathways of viruses. Utilizing stronger pesticides may control insect populations but could also lead to resistance issues, environmental concerns, and negatively impact beneficial organisms. Therefore, focusing on preventing wounds and managing insect populations directly addresses the root causes of virus transmission.
