A manual backpack-type sprayer Space treatment against mosquitoes using a thermal fogger Grubbs Vocational College students spraying Irish potatoes. Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
A crop-duster spraying pesticide on a field A self-propelled crop sprayer spraying pesticide on a field Pesticides are substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides, and many others (see table). The most common of these are herbicides, which account for approximately 50% of all pesticide use globally. Most pesticides are used as plant ...
Agricultural spray adjuvants do not reduce the amount of pesticide needed below the recommended use rate on a pesticide label. In fact, it is illegal to use a pesticide in the US outside of the instructions on the label, although FIFRA , the US law governing pesticide use, does allow for the use of pesticides at rates below the label, as long ...
Pesticides can enter the body through inhalation of aerosols, dust and vapor that contain pesticides; through oral exposure by consuming food/water; and through skin exposure by direct contact. [96] Pesticides secrete into soils and groundwater which can end up in drinking water, and pesticide spray can drift and pollute the air.
The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient. The AI is usually formulated with other materials (adjuvents and co-formulants) and this is the product as sold, but ...
For example, the spruce budworm, a destructive pest of spruce and balsam fir, has been monitored using pheromone traps in Canadian forests for several decades. [33] In some regions, such as New Brunswick, areas of forest are sprayed with pesticide to control the budworm population and prevent the damage caused during outbreaks. [34]
ULV spraying is a well-established spraying technique [2] and remains the standard method of locust control with pesticides and is also widely used by cotton farmers in central-southern and western Africa. It has also been used in massive aerial spraying campaigns against disease vectors such as the tse-tse fly.
For example, birds may be poisoned when they eat food that was recently sprayed with insecticides or when they mistake an insecticide granule on the ground for food and eat it. [19] Sprayed insecticide may drift from the area to which it is applied and into wildlife areas, especially when it is sprayed aerially.
