CITA

Specialized Weed Control for Rice Production

In the cultivation of rice, managing weed pressure without causing phytotoxicity to the crop is a complex challenge. The herbicide "Cita," manufactured by Hangzhou Darong Chemical Co., Ltd. (China), provides a focused solution for rice growers facing heavy infestations of barnyard grass and sedges. Based on the active ingredient penoxsulam, it acts as a selective, systemic herbicide that targets the metabolic processes of weeds.

Why Cita stands out

• High Selectivity: Designed as a selective herbicide, Cita effectively eliminates broadleaf weeds and grasses from the protected list while leaving the rice plants unaffected, provided the application rates are followed.
• Systemic Efficacy: Unlike contact herbicides that only affect the surface, Cita is absorbed through the leaves and travels systemically throughout the plant. This is essential for controlling robust weeds like barnyard grass in dense rice paddies.
• Practical Formulation: The suspension concentrate format is highly stable and ensures optimal coverage during foliar application, which is crucial for achieving consistent results.

Guidelines for Use: Cita is a post-emergence "insurance" herbicide. The application rate is between 0.05 and 0.1 liters per hectare. A key operational constraint is that only one application is permitted per growing season, with a mandatory 40-day pre-harvest interval. This requires precise planning and accurate timing to capture the weeds during their most vulnerable stage of development.

Limitations and Considerations: Being a specialized tool, Cita is optimized for barnyard grass and sedges. On fields with diverse weed populations, it may need to be integrated into a tank mix to achieve total weed control. Additionally, as a class 3 hazard substance, standard safety protocols and protective equipment are mandatory during mixing and application.

Who should use Cita? It is an ideal choice for large-scale rice farms that require a reliable, selective post-emergence solution to maintain field cleanliness and prevent yield loss from weed competition.
