About this product

A label built around waiting. Repeat sprays are 7 to 14 days apart, and the harvest waits run from 1 day for sweet corn and tomatoes to 7 days for broccoli and peppers, 14 for pears and 21 for pecans. It gives no rainfast time, only to spray when no rain is predicted for 24 hours.

Using this specific product

Ortho Garden, Tree & Shrub Insect Killer Concentrate is listed here as the Concentrate insecticide version for shrubs, trees, and garden vegetables. For treating a lawn or garden area, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Concentrate insecticide; related versions can use different timing.
  • For shrubs, trees, and garden vegetables, pay particular attention to wind, dry foliage, application rate and forecast.
  • The source gives no conditions for this time.

How to check readiness

Use the rainfast claim only for rain; use the label separately for people and pet re-entry. The label says to wait 7 to 14 days between applications on shrubs and trees, and at least 7 days in general.

Avoid this mistake

Rainfast does not mean dry, harmless or ready for people and pets.
