CHECK (Nichino Chemical India) PRETILACHLOR 50% EC is a selective pre-emergence herbicide that effectively controls a broad spectrum of annual grasses and certain broadleaf weeds in a variety of upland crops. It is particularly effective against Cyperus rotundus (nutsedge), a persistent and challenging weed.

Key Features:

• Selective pre-emergence herbicide with broad-spectrum control of annual grasses and select broadleaf weeds
• Outstanding efficacy against Cyperus rotundus (nutsedge)
• Provides long-lasting residual control
• Rainfast within two hours of application
• Low-odor formulation

Mode of Action:

PRETILACHLOR, the active ingredient in CHECK, disrupts chlorophyll synthesis by inhibiting the enzyme protoporphyrinogen oxidase (PPO). This critical enzyme is essential for the production of chlorophyll, the pigment that enables photosynthesis in plants. Without chlorophyll, plants cannot harness sunlight for energy production, leading to stunted growth and eventual death.

Application Recommendations:

CHECK is suitable for application in various upland crops, including rice, corn, sugarcane, and sorghum. The recommended dosage ranges from 0.75 to 1.5 liters per hectare. CHECK should be applied as a pre-emergence spray, either before or immediately after planting. Proper soil incorporation is crucial for effective weed control.

Safety Precautions:

CHECK is classified as a moderately hazardous pesticide. It is essential to wear appropriate personal protective equipment (PPE) when handling and applying the herbicide. Avoid contact with eyes, skin, and clothing. Do not apply CHECK in areas with a risk of water contamination.

Environmental Considerations:

PRETILACHLOR exhibits moderate persistence in soil and water. Responsible use practices are essential to minimize environmental impact. Avoid excessive application rates and follow recommended application guidelines.

Overall Significance:

CHECK (Nichino Chemical India) PRETILACHLOR 50% EC stands out as a versatile and effective pre-emergence herbicide, offering long-lasting control against a wide range of weeds, including the notoriously persistent Cyperus rotundus. It is a valuable tool for upland crop growers seeking effective weed management solutions.
