Topmix (Anu Products Limited) (Metsulfuron methyl 10% + Chlorimuron Ethyl 10% WP) is a broad-spectrum herbicide manufactured by Anu Products Limited. It is a wettable powder (WP) formulation containing 10% metsulfuron methyl and 10% chlorimuron ethyl, two potent sulfonylurea herbicides with different modes of action. This combination of herbicides provides broad-spectrum activity against a wide range of grasses, sedges, and broadleaf weeds.

Mode of Action:

• Metsulfuron methyl: Metsulfuron methyl inhibits the synthesis of branched-chain amino acids (BCAAs) in susceptible plants. BCAAs are essential for plant growth, and their inhibition leads to chlorophyll bleaching, stunted growth, and eventually death.

• Chlorimuron ethyl: Chlorimuron ethyl inhibits the synthesis of isoleucine and valine, two BCAAs, in susceptible plants. It also inhibits the synthesis of chlorophyll and carotenoids, leading to chlorophyll bleaching and photobleaching.

Dosage and Application: The recommended dosage of Topmix varies depending on the crop, soil type, and weed pressure. For most crops, the recommended dosage is 25-50 g per hectare. Topmix should be applied as a pre-emergence or early post-emergence herbicide. It can be applied as a broadcast application to the soil surface or as a directed spray to the base of weeds.

Application method: Broadcast application to the soil surface or as a directed spray to the base of weeds

Safety precautions:

• Wear appropriate personal protective equipment (PPE), including gloves, goggles, and a respirator, when handling Topmix.
• Avoid contact with skin and eyes.
• Do not apply Topmix to rice that is stressed or damaged.
• Do not graze animals on treated areas until the herbicide has completely degraded.
• Dispose of empty Topmix containers safely.

Additional information:

• Metsulfuron methyl is a moderately persistent herbicide, so it is important to follow label instructions carefully to avoid environmental contamination.
• Chlorimuron ethyl is a moderately persistent herbicide, so it is important to follow label instructions carefully to avoid environmental contamination.
• Topmix is not highly toxic to bees, so it can be applied to flowering rice with caution.

Benefits of Using Topmix:

• Broad-spectrum activity against a wide range of grasses, sedges, and broadleaf weeds
• Combination of two potent herbicides with different modes of action for better efficacy
• Long residual activity
• Easy to apply
• Environmentally friendly

Safety and Precautions:

• Topmix is a moderately toxic herbicide. It is important to follow all safety precautions when handling and applying this product.
• Wear appropriate personal protective equipment (PPE), including gloves, goggles, and a respirator, when handling Topmix.
• Avoid contact with skin and eyes.
• Do not apply Topmix to crops that are stressed or damaged.
• Do not graze animals on treated areas until the herbicide has completely degraded.
• Dispose of empty Topmix containers safely.

Conclusion: Topmix is a versatile and effective herbicide that can be used to control a wide range of grasses, sedges, and broadleaf weeds in a variety of crops. It is a good choice for farmers who are looking for a broad-spectrum herbicide with long residual activity and a good safety profile.
