Wiper FS

A systemic shield for emerging seedlings

«Viper FS» is a specialized seed treatment agent based on clothianidin, a member of the neonicotinoid class. Unlike contact insecticides, this molecule demonstrates high systemic activity, which is crucial for protecting crops during the most vulnerable period—from germination to the 3-5 true leaf stage.

Technical analysis

The product is formulated as a flowable suspension concentrate (FS). This formulation was specifically chosen by the developers at Hebei Veyong Bio-Chemical Co., Ltd. for its physical properties. Due to the fine particle size of the active ingredient, «Viper FS» provides:

• Uniform coverage across the seed surface, preventing gaps in the protective layer.
• Excellent adhesion, which minimizes dust-off during mechanical seeding.
• Rapid absorption: once the seed enters moist soil, clothianidin migrates into the root zone, establishing a protective halo around the seedling.

Protection mechanism and performance

Clothianidin disrupts nervous system impulses in pests by binding to nicotinic acetylcholine receptors. This ensures effective control of a broad complex of soil-borne and early-stage above-ground pests, including wireworms, cutworms, flea beetles, and frit flies. The systemic action guarantees that even if a pest attempts to feed on the seed or roots, it will ingest a lethal dose.

Application is limited to a single treatment per season, in accordance with safety regulations for corn and sunflower cultivation. Classified as hazard class 3, the product requires standard precautions. However, its high biological activity allows for low dosage rates, effectively reducing the overall pesticide load on the soil ecosystem.
