Professional crop protection: The Acidan approach

Effective management of fungal diseases in intensive agriculture requires solutions that combine speed and durability. "Acidan w.p.", manufactured by Shanghai-based Sunrise Chemicals Co. Ltd., is a versatile fungicide designed to bridge the gap between contact and systemic protection. Distributed in various markets by Khimagromarketing, this product is a staple for growers seeking to control aggressive pathogens in tomatoes, potatoes, and grapevines.

Dual-action technology

The core strength of Acidan lies in its formulation, which includes metalaxyl and mancozeb. This combination offers a multi-layered defense strategy:

• Systemic action (metalaxyl): Absorbed into the plant tissues, it provides curative protection by stopping fungal growth from within, including protection for new growth stages.
• Contact action (mancozeb): Acts as a preventive shield on the surface of foliage, preventing pathogen spores from successfully germinating.

This dual mechanism is specifically effective against diseases such as alternaria, phytophthora, downy mildew, and peronosporosis. By integrating both modes of action, Acidan acts as a reliable tool in disease resistance management.

Application guidelines

To maximize the efficacy of Acidan w.p., agricultural producers should adhere to the following technical parameters:

• Application rate: 2–2.5 kg/ha, depending on crop density and infection pressure.
• Frequency: Maximum of 3 applications per growing season.
• Pre-harvest interval: 20–30 days must elapse between the final treatment and harvest.
• Safety: The product is classified as toxicity class 3, requiring appropriate protective gear and adherence to standard pesticide handling safety protocols.

Supplied as a wettable powder, Acidan is designed for easy mixing in spray tanks. It is a proven choice for farmers looking for a balanced, cost-effective fungicide that can handle high-moisture conditions where fungal pressure is most acute.
