Weeds are mainly killed by absorbing chemicals through coleoptile and mesodermal axis.

Crotamiton is an enamide resulting from the formal condensation of crotonic acid with N-ethyl-2-methylaniline. A colourless or pale yellow oily liquid, it is used in the treatment of pruritus (itching) by producing a counter-irritation: as it evaporates from the skin, it produces a cooling effect that diverts attention away from the itching. It has also been used as an acaricide in the treatment of scabies, though more effective drugs are usually preferred. It has a role as an antipruritic drug and a scabicide.

Osthol is a substance extracted from the fruit of Fructus Cnidii, an annual herb in Umbelliferae. It has antispasmodic, hypotensive, antiarrhythmic, enhancing immune function and broad-spectrum antibacterial effects. Clinically, it is mainly used to treat male impotence, scrotal wet itching, female vaginal itching, uterine cold infertility, rheumatic arthralgia, scabies wet sore and trichomonal vaginitis. Osthol can also be used as a field insecticide and bactericide. It mainly has contact killing effect, supplemented by gastric toxicity. The drug solution is absorbed into the insect body through the body surface and acts on the insect nervous system, resulting in the non functional contraction of the insect muscle and eventually exhaustion and death. It has a good contact killing effect on a variety of pests such as cabbage worm, tea inchworm, cotton bollworm, beet armyworm and various aphids.
