Dursban Ultra

Reliable Protection Against Complex Pests: Dursban Ultra

When orchards or hop yards face a multi-pest infestation, targeted insecticides are often insufficient. Dursban Ultra, manufactured by Zhuhai Kwaoji Overseas Trade Co., Ltd. for Kemiline Agro, is a robust contact insecticide and acaricide based on chlorpyrifos. It serves as a "heavy-duty" solution designed to eliminate pests where they hide, providing immediate control over both chewing and sucking insects.

Key Advantages of Dursban Ultra

What sets Dursban Ultra apart is its high contact activity, which is crucial for managing populations of pests that have developed resistance to modern, more selective products. It provides an essential layer of security for growers dealing with stubborn infestations.

• Broad Spectrum: Effectively controls weevils, mites, leaf rollers, codling moths, cutworms, thrips, and various scale insects.
• Contact Efficacy: The active ingredient acts immediately upon contact, halting pest damage to the crop almost instantly.
• Superior Formulation: As an emulsifiable concentrate, it ensures excellent coverage and adhesion to the plant surface, minimizing runoff.

Application and Safety Guidelines

Dursban Ultra is classified as a Hazard Class 2 product, requiring strict adherence to safety protocols during spraying. Because the pre-harvest interval ranges from 30 to 40 days, this product is best suited for application during the early to mid-vegetation stages, rather than immediately before harvest. With a maximum of two applications allowed per season, it fits perfectly into a well-planned integrated pest management (IPM) strategy.

This insecticide is an optimal choice for professional-grade agriculture, particularly for apple orchards, vineyards, and hop production, where crop quality is paramount. By applying the recommended dosage of 1–3 L/ha, agronomists can effectively suppress high-density pest populations and ensure the health of their crops throughout the growing season.
