Polkar

Systemic rapeseed protection: why choose Polkar

For farmers growing winter rapeseed, pest control is always a matter of timing and efficacy. The insecticide "Polkar," based on acetamiprid, belongs to the neonicotinoid class, which is considered the current gold standard for controlling hidden and sap-sucking pests. Unlike contact-only agents, Polkar provides a systemic effect: it penetrates plant tissues, protecting them against the cabbage seed weevil, flea beetles, and cabbage aphids for several weeks.

Key advantages

• Systemic knockdown effect: The active ingredient rapidly blocks the nervous system of pests, causing their death regardless of whether they ingested the treated plant material or simply made contact with it.
• Technological excellence: The water-dispersible granule formulation ensures perfect mixing in tank mixes without clogging spray nozzles.
• Economic flexibility: A dosage rate of 0.5–1.0 L/ha allows for adjusting treatment intensity based on the current pest pressure in the field.

Application details

It is important to note that Polkar is a Class 2 hazard substance, requiring standard protective measures during handling. The systemic nature of the product is its primary advantage, but it also dictates strict application timing: the final treatment must be applied no later than 30 days before harvest. The maximum limit of two treatments per season allows farmers to cover the critical growth phases of rapeseed effectively.

The product is manufactured by the facilities of Nanjing Red Sun Co., Ltd and Nanjing Essence Fine-Chemical Co. Ltd, ensuring consistent active ingredient concentration in every batch. Polkar is the optimal choice for operations seeking a balance between cost-per-hectare and deep plant penetration for reliable crop protection.
