Applications

Propargite can effectively prevent and cure acarid genus of apple tree, cotton, cucumber, grape, corn, nut, soybean, drupe, tomato etc. Non-systemic acaricide with predominantly contact action; some additional action by inhalation.  Uses Control of phytophagous mites (particularly motile stages) on a variety of crops, including vines, fruit trees (e.g. top fruit, stone fruit, citrus fruit), hops, nuts, tomatoes, vegetables, ornamentals, cotton, maize, peanuts, and sorghum. Used at rates from 0.75-1.8 kg/ha on row crops and foliar sprays of 0.85-3.0 kg/ha on perennial fruit and nut crops. Phytotoxicity Phytotoxic to pears, strawberries, roses, and cotton under 10 inches in height. Citrus fruit and beans may also show some injury. 

Pyridaben is a non-systmic insecticide and acaricide, Rapid knock-down and long residual activity. It is a METI acaricide that inhibits mitochondrial electron transport at complex I (METI; Ki = 0.36 nmol/mg protein in rat brain mitochondria). Pyridaben is active against a variety of mites, inducing 100% mortality of C. malaccensis, D. farina, and T. putrescentia when administered via filter paper contact at doses of 25, 100, and 200 mg/m3, respectively. Active against all the developing stqages, especially against the larval and nymph stages. Control of red spiders on cotton, soya bean, fruit trees, ornamentals and vegetables at 5-20g/hl or 100-300kg/ha.

 

The combination of Propargite + Pyridaben is a powerful acaricide (mite control) mixture used in agriculture to manage resistant mite populations. Here's a detailed guide on its application:

 

1. Target Pests

• Propargite (a cholesterol biosynthesis inhibitor)

  • Effective against all motile stages of spider mites (Tetranychus spp., Panonychus ulmi).

  • Weak on eggs but has translaminar activity.

• Pyridaben (a mitochondrial electron transport inhibitor, METI)

  • Kills eggs, larvae, nymphs, and adults with contact and stomach action.

  • Strong against resistant mite strains.

Best for:
Spider mites (two-spotted, red, citrus rust mites)
Mites with resistance to single-mode-of-action acaricides

 

2. Recommended Crops

• Fruits: Apples, grapes, citrus, strawberries.

• Vegetables: Cucumbers, tomatoes, eggplants.

• Field Crops: Cotton, soybeans.

• Ornamentals: Roses, nursery plants.

(Always verify crop safety on the label-some formulations may have restrictions.)

 

3. Application Guidelines

Dosage & Mixing

• Typical mix ratio:

  • Propargite 40% EC: 0.5-1 L/ha

  • Pyridaben 20% WP/SC: 300-500 g/ha

  • Adjust based on pest pressure and crop canopy density.

• Water volume: 500-1000 L/ha (ensure full coverage).

• Compatibility: Generally compatible, but conduct a jar test before large-scale mixing.

Timing & Frequency

• Apply at first sign of mites (before heavy webbing).

• Reapply every 10-14 days if needed (max 2-3 applications/season to delay resistance).

• Avoid spraying during peak heat (>30°C) to reduce phytotoxicity risk.

Method

• Use high-pressure sprays to penetrate webbing and cover leaf undersides.

• Add a sticker/spreader (e.g., silicone-based adjuvants) for better adhesion.

 

4. Advantages of the Mixture

 Broad-spectrum control: Targets all mite life stages (eggs to adults).
 Resistance management: Dual modes of action reduce resistance risk.
 Longer residual activity: Pyridaben provides extended protection.

 

5. Precautions & Limitations

• Phytotoxicity: Pyridaben can harm certain crops (e.g., young cucurbits) under stress.

• Bee toxicity: Pyridaben is highly toxic to bees-apply at dusk/dawn when pollinators are inactive.

• Pre-harvest intervals (PHI):

  • Propargite: 14-30 days (varies by crop).

  • Pyridaben: 7-21 days.

• Resistance risk: Rotate with non-METI acaricides (e.g., bifenazate, etoxazole).

 

6. Example Commercial Formulation

• Propargite 30% + Pyridaben 10% SC:

  • Dose: 1-1.5 L/ha in 500 L water.

  • Re-entry interval (REI): 24 hours.

 

7. Alternatives for Resistance Management

Rotate with:

• Bifenazate (respiration inhibitor)

• Spirodiclofen (lipid synthesis inhibitor)

• Fenpyroximate (METI, but different binding site than pyridaben).
