Rimaster WG

Reliable Maize Protection: Using Rimaster, WG in the Field

Managing weed pressure in corn crops requires a herbicide that is both powerful and reliable. Rimaster, WG, manufactured by Parijat Industries (India) Pvt. Ltd., is a systemic selective herbicide based on rimsulfuron. Designed as a post-emergence control solution, it is highly valued by growers for its ability to stop weed growth by inhibiting cell division shortly after application.

Field Experience and Application Tips

From an operator's perspective, the ease of mixing is a major advantage. Since it comes in water-dispersible granules, it dissolves quickly without leaving residues that could clog sprayer nozzles, making maintenance simple and efficient. Because this is a post-emergence (insurance) herbicide, timing is critical: it works best when weeds are in the early 2-4 leaf stage.

Targeting Weeds Effectively

Rimaster, WG shows excellent selectivity, meaning the maize crop tolerates it well while it targets the most problematic weed species, including:

• Grasses: Common couch (Elymus repens), Barnyard grass, Yellow foxtail.
• Broadleaf weeds: Common lambsquarters, Redroot pigweed, Shepherd's purse, Common ragweed, Chickweed.

A crucial management point is that the product is limited to one application per season. This requires precise planning to ensure you maximize its effect within the single window of opportunity. Classified under hazard class 3, standard safety measures for handling crop protection products apply.

In practice, using Rimaster, WG leads to rapid results: weed growth ceases almost immediately, with total control achieved within 10-20 days. This gives the maize the competitive advantage it needs to thrive without the stress of nutrient or moisture competition from weeds during its early development stages.
