Picoxystrobin – A Reliable Solution For Early-Season Disease Protection

In today’s unpredictable climate conditions, disease pressure on crops is increasing. Protecting plant health from the early stages is essential to secure yield and quality.

Picoxystrobin, a fungicidal active ingredient from the Strobilurin (QoI – IRAC 11) group, originally developed by Syngenta and later commercialized by DuPont, has become a trusted choice for preventive control of fungal diseases across a wide range of crops.

Mode of Action

Picoxystrobin blocks mitochondrial respiration in fungal cells, stopping electron transport and causing a loss of energy, which prevents fungal growth and leads to cell death.

Thanks to its translaminar movement and good surface redistribution, the active ingredient spreads well across the leaf surface and into plant tissues — supporting uniform and long-lasting protection, even on areas that spray droplets may not directly reach.

Toxicity & Safety

• Picoxystrobin has low acute toxicity to humans and warm-blooded animals (LD₅₀ > 2,000 mg/kg according to FAO reports).

• However, it should be noted that it may pose risks to aquatic organisms and soil ecosystems if overused or washed into waterways.

Key Benefits for Farms & Agribusinesses

• Long-lasting preventive effect, helping reduce spray frequency and labor costs.

• Even leaf coverage due to good redistribution, limiting disease “hot spots”.

• Supports strong plant physiology and sustained photosynthesis → improves yield potential.

• Relatively safe profile, aligning with sustainable agriculture and IPM practices.

• Compatible with DMI and SDHI fungicides, enabling effective rotation to prevent resistance.

Disease Control Across Crop Types

• Rice & cereals: Effective against rice blast (leaf & neck) and brown spot; helps maintain green, healthy foliage for better photosynthesis.

• Vegetables (melon, tomato, pepper, leafy greens…): Controls powdery mildew, anthracnose, leaf spot, helping maintain clean foliage and vigorous growth.

• Fruit trees (citrus, mango, longan, durian…): Prevents anthracnose and related fungal lesions, protecting flower clusters, young shoots, and fruit set.

• Industrial & perennial crops (tea, coffee, pepper…): Reduces rust and leaf spot, helping maintain stable canopy health and sustained productivity.

Most effective when applied preventively or at the very early stage of disease.

Stewardship & Safe Use

• Best used early — curative effect is limited when disease is severe.

• Always rotate modes of action to reduce resistance pressure.

• Follow recommended PPE, re-entry intervals, and pre-harvest intervals.

• Avoid runoff into aquatic environments and waterways.

Conclusion

Picoxystrobin provides a stable, flexible, and sustainable disease management solution, helping both agricultural enterprises and farmers maintain consistent yield and crop quality.

Protecting the crop early is the key to safeguarding the entire season’s productivity and value.
