Simazine is a selective triazine herbicide widely used for the pre-emergence control of annual broadleaf and grass weeds in a variety of crops.It works by being absorbed through the roots and translocated to the leaves, where it inhibits photosynthesis, leading to the suppression of weed growth.Simazine is known for its long residual activity, excellent stability, and cost-effectiveness, making it a reliable choice for both agricultural and scientific applications.

Simazine is mainly applied before weed emergence (pre-emergence) to control unwanted vegetation in:
Corn and sugarcane fields
Citrus orchards and vineyards
Tea plantations and non-crop areas
Mode of Action:
Absorbed by the roots and translocated through the xylem to the leaves, Simazine inhibits photosystem II during photosynthesis, leading to chlorosis and plant death.
Effective against annual broadleaf and grassy weeds
Long-lasting soil activity
Reduces the need for manual weeding
Compatible with other herbicides for integrated weed management
