Fenpyroximate 5% SC

About Fenpyroximate 5% SC

Fenpyroximate 5% SC is a highly effective, broad-spectrum acaricide (miticide) and insecticide widely used in agriculture to control various species of plant-damaging mites.

The "SC" stands for Suspension Concentrate, a water-based formulation that makes it easy to mix, offers great foliage coverage, and is generally safer for the crop compared to EC (Emulsifiable Concentrate) formulations.

Here is a comprehensive breakdown of how it works, what it controls, and how to use it safely.

Mode of Action: How It Works

Fenpyroximate belongs to the METI (Mitochondrial Electron Transport Inhibition) class of chemicals (IRAC Group 21A).

• Energy Disruption: It works by inhibiting Complex I in the mitochondrial respiratory chain of the pest. This blocks ATP (energy) production, causing the mite to rapidly stop feeding and paralyze.

• All-Stage Control: It targets multiple life stages of mitesincluding larvae, nymphs, and adults. It also inhibits molting in nymphs and reduces egg-laying (oviposition) in females, breaking the pest's reproductive cycle.

• Knockdown and Residual: It provides a quick contact "knockdown" effect alongside long-lasting residual control (typically 3 to 4 weeks).

Target Pests

It is highly effective against phytophagous (plant-eating) mites, including:

• Red Spider Mites (Tetranychidae)

• Yellow Mites

• Pink & Purple Mites

• Eriophyid Mites (Rust/Blister mites)

• Broad Mites (Tarsonemidae)

• Secondary control: It also shows efficacy against certain sucking pests like whiteflies, leafhoppers, and psyllids.

Major Crops & Standard Dosages

Fenpyroximate 5% SC is extensively used in cash crops, horticulture, and plantations.

Best Application Practices

• Thorough Coverage is Key: Fenpyroximate relies heavily on contact and stomach action. Mites usually live on the undersides of leaves, so ensure your spray thoroughly covers both the upper and lower leaf surfaces.

• Use an Adjuvant: Mixing a silicone-based spreader/sticker can significantly improve leaf penetration and chemical longevity.

• Resistance Management: To prevent mites from developing resistance, avoid using Fenpyroximate or other METI inhibitors sequentially. Alternate it with miticides from different chemical classes (e.g., Abamectin, Spiromesifen, or Hexythiazox).

Safety & Environmental Precautions

• Aquatic Toxicity: Fenpyroximate is highly toxic to fish and aquatic invertebrates. Do not spray near water bodies or allow chemical drift to reach ponds or streams.

• Beneficial Insects: It is relatively safe for beneficial predatory mites and honeybees when used at recommended doses, making it suitable for Integrated Pest Management (IPM) programs.

• PPE: Always wear protective gear (gloves, mask, and goggles) during mixing and application. Do not spray during the peak heat of the day.
