To avoid injury to your plants when you are spraying in the heat of the summer, always water the day before you plant to spray (unless you've had rain) to make sure the plants are hydrated. Spray injury is much more likely when plants are stressed due to lack of water. Spray injury can occur if you spray in the bright sun during the heat of the day because the combination of the heat and the chemicals can burn the foliage. Most chemicals should not be sprayed when the temperature is above 85°F or 90°F. During the summer, the best time to spray is in the early morning or in the evening.
The best advice is to cut back the injured leaves/fronds and leave any growth that is not damaged. If all the foliage is damaged, you can cut the plants back entirely. They will put up new growth but they won't grow as full this season. Next year they should be fine. Feed them with Plant-tone or Holly-tone and keep them watered. You could even give them a shot of Scotts Miracle-Gro to give them a quick shot of fertilizer.
