What is the optimal temperature range for applying foliar treatments?

• A. 50 to 70 degrees F
• B. 60 to 80 degrees F
• C. 70 to 90 degrees F
• D. 55 to 75 degrees F

Answer: (B)

The optimal temperature range for applying foliar treatments is 60 to 80 degrees F because this range allows for effective absorption of the pesticide by the plant leaves while minimizing potential phytotoxicity. In warmer temperatures, such as those above 80 degrees F, the risk of damage to the plant increases, as higher temperatures can cause the foliage to be more sensitive and susceptible to injury from the chemical application. Conversely, applying treatments at temperatures below 60 degrees F may slow down the absorption and efficacy of the product, potentially reducing its effectiveness in managing pests or diseases. Therefore, the 60 to 80 degrees F range strikes a balance that promotes both effectiveness and safety during application.
