Picoxystrobin 22.52% w/w SC

Picoxystrobin 22.52% w/w SC is a modern, broad-spectrum systemic fungicide belonging to the strobilurin (QoI) group.¹ It is widely used in agriculture for its ability to provide both preventive and curative protection against a variety of fungal diseases.

Key Technical Details

• Mode of Action: It inhibits mitochondrial respiration in fungi, effectively "suffocating" the fungal cells and preventing them from producing energy.

• Movement in Plant: It is highly unique because it offers systemic, translaminar, and vapor activity. This means it moves through the plant tissues and can even redistribute through the air to protect parts of the plant that weren't directly sprayed.

• Formulation: SC (Suspension Concentrate), which is a stable flowable liquid designed to be diluted with water.

Common Applications & Dosage

It is used across a variety of high-value crops. Below are the typical recommendations:

Benefits

• Preventive & Curative: Best applied before disease appears, but it can also stop early-stage infections.

• Green Leaf Effect: Often helps plants stay greener for longer (increased photosynthesis), which can lead to better yields.

• Rainfastness: Generally becomes rainfast within 12 hours after application.

Safety & Precautions

• Hazard: It is toxic to aquatic life; avoid spraying near water bodies.

• Sensitive Crops: Be cautious near certain varieties of pear, strawberry, and sweet cherry, as some strobilurins can be phytotoxic to them.

• PPE: Always wear gloves, a mask, and protective eyewear during mixing and application.

• Resistance Management: To prevent fungi from becoming resistant, avoid using this fungicide more than 23 times per season; rotate with fungicides from different chemical groups (e.g., Triazoles).
