What is your target pest? And what is the product? With this information we can try to give you more specific recommendations/cautions.
Iceplant is known for minimal pest and disease issues. But there are possible issues, primarily with fungal disease.
Sulfur is most commonly used as a fungicide, but there are many insecticide products that also contain sulfur. Read the product label and cautions for phyto-toxicity for specific plants.
Sulfur can cause plant injury if applied during dry periods of 80 degrees Fahrenheit or above.
Never apply sulfur if the plant was treated with oil pesticides within 20 to 30 days. The sulfur negatively reacts with the oil pesticide and creates a toxic reaction that will damage the plants.
Good cultural practices and sanitation can prevent or minimize fungal infections of ice plants.
Prune plants regularly and remove weeds to improve air circulation and reduce fungal growth.
Avoid overhead irrigation during cool weather.
Consider watering in the morning hours so that plants dry during the day.
Do not over- or under-fertilize as it may increase the chances of infection.
