Simazine, a triazine herbicide developed by Ciba-Geigy (Switzerland), acts by inhibiting photosynthesis and is widely used to control weeds in cropland, lawns and the like. Although it is almost ineffective when applied to foliage, it is said to exhibit herbicidal activity against nearly all postemergent annual weeds by soil treatment. The registration standards of the Ministry of Environment state that simazine should not be detected in rice, wheat and barley, miscellaneous grain crops, fruits, vegetables, tubers, pulses and tea.

Simazine is not a medical substance. It is a herbicide, specifically a pre-emergent herbicide, used to control broadleaf weeds and annual grasses [1]. It works by inhibiting photosynthesis in plants [2]. Simazine is banned in the European Union but is still used in some other countries, including the United States [2].
Here are some additional details about simazine:
- It is an off-white crystalline compound that is sparingly soluble in water [2].
- It remains active in the soil for two to seven months or longer after application [2].
- It has been classified by the EPA as a possible human carcinogen [1].
