Agrichemicals are chemicals used in agricultural production.
Many of them are used as sprays to control insects or other pests,
weeds or plant diseases. Sometimes - due to weather conditions, the
nature of the landscape (hills, shelterbelts, etc) and the way the
operator carries out the spraying - the spray drifts away from the
target crop or area. This is known as spraydrift.

applying agrichemicals - Responsiblities of applicators.
Spraydrift can affect your health, how badly will depend on such
things as the extent of the drift, the chemical makeup of the
spray, and the concentration of the spray. If you have concerns
about your health, after there has been spraying in your area,
contact your doctor or health professional.
