Sansani (Pyrazosulfuron-ethyl 10% WP) is a selective pre-emergent herbicide from Ichiban Crop Science that is effective against a wide range of broadleaf weeds and grasses in rice. It works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for the synthesis of branched-chain amino acids in plants. This leads to the death of the plant.

Key Features:

• Selective: Sansani is a selective herbicide, which means that it is effective against a wide range of weeds without harming rice plants.
• Pre-emergent activity: Sansani is a pre-emergent herbicide, which means that it kills weeds before they emerge from the soil. This helps to prevent weeds from competing with rice plants for water and nutrients.
• Translaminar activity: Sansani has translaminar activity, which means that it can penetrate plant leaves and control weeds that are difficult to reach with other herbicides.
• Rainfastness: Sansani is rainfast within 1 hour of application, ensuring that it remains effective even if it rains.
• Long-lasting residual activity: Sansani has long-lasting residual activity, which means that it continues to control weeds for a long period of time after application.

Benefits:

• Controls a wide range of broadleaf weeds and grasses in rice: Sansani is an effective herbicide for controlling a wide range of weeds in rice, including both annuals and perennials.
• Provides long-lasting control of weeds: Sansani's pre-emergent activity, translaminar activity, and long-lasting residual activity provide long-lasting control of weeds, reducing the need for repeat applications.
• Is safe for rice plants: Sansani is selective to rice plants, so it can be used safely in rice crops.
• Is relatively safe for the environment, with low toxicity to fish, birds, and other non-target organisms.

Application:

Sansani should be applied as a foliar spray to the soil surface before weeds emerge. Please refer to the product label for specific application instructions and dosage recommendations for each weed species.

Safety Precautions:

As with any herbicide, it is important to follow safety precautions when using Sansani:

• Wear protective clothing, including gloves, goggles, and a mask, during application.
• Avoid contact with skin and eyes.
• Wash hands thoroughly after handling the product.
• Keep Sansani out of reach of children and pets.

Environmental Considerations:

Sansani is classified as a moderately hazardous herbicide. To minimize environmental impact, follow proper disposal procedures for empty containers and unused product. Avoid contamination of water sources.

Storage:

Store Sansani in its original container in a cool, dry, and well-ventilated area. Keep away from direct sunlight and heat sources.

Conclusion:

Sansani is a valuable tool for managing broadleaf weeds and grasses in rice. It is a selective pre-emergent herbicide that provides long-lasting control of weeds, without harming rice plants. Sansani is relatively safe for the environment and is easy to use.

Specific weeds controlled by Sansani in rice:

• Broadleaf weeds: Amaranth, barnyardgrass, chickweed, crabgrass, duckweed, goosegrass, junglerice, morning glory, nutsedge, pigweed, and many others.
• Grasses: Barnyardgrass, crabgrass, goosegrass, junglerice, and many others.

Sansani is a valuable tool for integrated weed management (IWM) programs in rice. It can be used to control a wide range of weeds in rice crops, and it is relatively safe for the environment.
