Fenamiphos is an organophosphate insecticide and nematicide used for the control of nematodes and sucking insects (including aphids and thrips) on food and non-food crops, and for the control of nematodes in the turf. Fenamiphos blocks the enzyme acetylcholinesterase in the target pests. Fenamiphos is a highly toxic poison that acts by inhibiting cholinesterase (ChE) enzymes in the blood and central and peripheral nervous systems. Inhibition of plasma cholinesterase activity is the most sensitive toxicological endpoint in acute and short-term studies on experimental animals. Fenamiphos is applied on a variety of plants such as tobacco, turf, bananas, pineapples, citrus, and other fruit vines, some vegetables, and grains. In Brazil, this pesticide has been extensively used in tomato crop at planting and also in melon.

Ponazuril, sold by the Bayer Corporation under the trade name Marquis, was the first FDA-approved treatment for equine protozoal myeloencephalitis (EPM) in horse, caused by Sarcocystis neurona. Also this drug was used in animals such as cats, dogs against coccidia, an intestinal parasite. Coccidia treatment is far shorter than treatment for EPM.

Diethyltoluamide (DEET) is an insect repellent used to keep insects away. This product is effective against mosquitoes, biting flies (gnats, sandflies, deer flies, stable flies, black flies), ticks, harvest mites, and fleas. DEET is absorbed through the skin. DEET has few adverse effects when applied as directed. The most common problem is local skin irritation, including erythema and pruritis, at the site of application.
