Metrix WP

Why «Metrix WP» is a staple for potato and tomato fields

When managing large areas of potatoes or tomatoes, controlling weeds before they even emerge is the golden rule of efficiency. Metrix WP, as a soil-applied systemic herbicide, acts as a reliable protective screen. Produced by Nanjing No.1 Pesticide Factory of Red Sun Group Co., Ltd., this product is designed for those who value precision and long-term protection against annual grasses and broad-leaved weeds.

Field Application and Handling

• Pre-emergence Strategy: The best results are achieved when the product is applied shortly after planting. Because it is a soil herbicide, soil moisture is key to activation. A well-prepared, fine-textured seedbed ensures the herbicide forms an even, unbroken barrier.
• Mixing Tips: Since it comes as a wettable powder, proper agitation is essential. I always recommend preparing a stock solution first to ensure no clumps end up in the sprayer tank, which saves a lot of time on cleaning nozzles later.
• Selectivity: Being a selective herbicide, it is generally safe for the target crop. However, always pay attention to your soil type—sandy soils require careful adjustment of the dosage to prevent potential crop stress.

Operational Insights

Operating with a Class 3 hazard level substance means that standard safety gear (respirator, gloves, and protective clothing) is mandatory. The formula is stable in the field, and because it is a systemic herbicide, it works from within the weeds once they try to germinate. After spraying, it is good practice to flush the sprayer system with clean water to prevent any powder residue from settling in the plumbing. With the right dose and timing, this herbicide from the Red Sun Group provides excellent, consistent results that keep the fields clean throughout the critical early growth stages.
