Spray foliage thoroughly when insects are first seen or if insects re-appear. Spray underneath the leaves to kill pests which may be hiding out of sight.

For hibiscus flower beetle, spray buds and flowers as needed. For longtailed mealybug, apply 3 sprays 2 weeks apart. For psyllids, spray at first sign and then a week later. For soft scales, spray in late spring or when small scales are first seen. Apply 3 sprays, 2 weeks apart.

For best results spray in the morning when there is little or no wind and little direct heat from the sun.

As a guide, 2 L of spray mixture should be sufficient to thoroughly spray a fruit tree up to 3m high, or to spray 10 large tomato plants.
