Chemicals are sprayed to control pests and diseases on farms, around the home and in gardens, parks and reserves. When chemicals are used, droplets are produced that can remain suspended in air and may be carried by wind away from the target area. This is known as ‘spray drift’.

Why are pesticides spray in the field?

As plants have already germinated, post-emergent pesticide application necessitates limited field contact in order to minimize losses due to crop and soil damage. These can be used for insects, weeds, and other pests to crops, humans, and animals.

Systemic insecticides are sprayed directly on foliage to be absorbed and carried throughout the vascular system of the plant. Sucking insects like aphids, mealybugs, and scale feed on the plant and die when the chemical is ingested.

What happens if you spray insecticide before rain?

Wind and rain may also be a factor—and could lead to unintended casualties. Avoid spraying insecticide before a rainfall to prevent chemicals from leaching through the soil and into the water table, where it can enter creeks and streams, poisoning fish and other wildlife.
