How to Apply Pest Sprays

Lettuce Grow | JUNE 16, 2022

Here’s the thing: When it comes to spray applications, the label is the law. When using any form of foliar sprays, we strongly recommend reading and carefully following all directions on the label.

If growing outside, we suggest that you spray plants in the late afternoon or early evening, to avoid any leaf burn from direct sunlight. That said, be sure to avoid spraying late at night. This will ensure that your plants aren't wet overnight from a spray application which can invite fungal disease.

Growing indoors? We recommend turning off your lights and leaving them off until any sprayed solution has completely dried. If you are growing near a window then you should apply pest sprays in the late afternoon or early evening to prevent the risk of leaf burn from indirect sunlight.

Wet leaf tissue can easily burn when exposed to high light levels, even those that aren’t directly from the sun.

When spraying, it’s important to get as even of an application as possible. You can achieve this by avoiding spraying when it’s windy and peeling back older leaves to make sure you’re getting good coverage on the underside. Be sure that your plants are adequately moistened, as most pesticides require direct contact with target pests.
