What should be avoided when applying pesticide to tender or wet leaves?

• A. Injury may occur.
• B. Leaves will stay dry.
• C. Pesticide will act faster.
• D. No effect on plant tissue.

Answer: (A)

The main idea here is plant safety: tender or freshly emerged leaves are more susceptible to pesticide injury, and having moisture on the leaves increases pesticide uptake. Spraying when leaves are wet or still tender can cause phytotoxic damage to the foliage, such as streaking, scorching, or necrosis. So the best practice is to avoid applying pesticides under those conditions and wait until leaves are dry and a bit more mature, following the label’s guidance. The other statements don’t reflect the real risk: spray won’t reliably keep leaves dry, faster action isn’t the goal and can come with greater injury risk, and while some tissue response can occur in general, the key risk when leaves are tender or wet is injury to the plant.
