Cinosulfuron

Cinosulfuron is a potent systemic herbicide belonging to the sulfonylurea chemical class. It is primarily developed and used for the selective control of various weeds in rice cultivation. Due to its systemic nature, it is absorbed by both leaves and roots, making it a versatile tool for weed management programs.

The mode of action of cinosulfuron involves the inhibition of the acetolactate synthase (ALS) enzyme. By interrupting the synthesis of essential amino acids, the herbicide effectively stops cell division and plant growth. Sensitive weeds typically exhibit growth cessation shortly after exposure, followed by chlorosis and eventual necrosis.

Cinosulfuron is specifically designed for rice paddies to target a broad spectrum of grasses, sedges, and broad-leaved weeds. Its selectivity ensures that the rice crop remains unharmed while effectively suppressing competing vegetation. It is highly valued for its ability to provide control throughout the growing season.

Successful application of cinosulfuron requires careful management of the water level in rice fields. For optimal biological efficacy, the herbicide needs a stable water layer to facilitate proper uptake by the target plants and consistent soil distribution. Maintaining appropriate moisture levels after application is critical for achieving the desired herbicidal effect.

• Excellent selectivity for rice safety.
• Low application rates per hectare.
• High systemic activity across weed species.
• Favorable environmental profile compared to older chemistries.

When handling cinosulfuron, operators must utilize proper protective equipment to minimize exposure. While it has low toxicity to non-target wildlife, it is essential to prevent drift towards non-target crops, which are often highly susceptible to sulfonylurea-based herbicides. Always follow local regulations and label recommendations for storage and disposal.
