Applications

Hexythiazox is one of thiazolidinone acaricides with an appearance of yellow or light brown liquid and wettable powder appearance of white powder, stored under cool and dry conditions two years without deterioration. Ambient temperature level does not affect the results, generally 10 days after the application in order to show better control effect, the persistence can maintain 50 days or so.  It is an acaricide for Eotetranychus carpini on alfalfa and clover seeds (24c), caneberries, Christmas trees, citrus and vines (field grown, nursery), cotton, hops, ornamentals, peppermint and spearmint, pistachios, pome fruit (apples, pears), stone fruit (including plums), strawberries, tree fruits and nuts (nonbearing).


Fenpropathrin is pyrethroid insecticides and acaricide with contact and stomach action, acting on Lepidoptera, Diptera and Heteroptera insect. It is used to control aphid, red spider, heart_eating worm, armworm, and noctuid.
 

This combination provides dual pest control against mites and insect pests, offering both preventive and knockdown action. Below is a comprehensive application guide.

 

1. Mode of Action & Target Pests

Hexythiazox

• Chemical Class: Thiazolidinone (IRAC Group 10A)

• Mode of Action: Chitin synthesis inhibitor (affects egg & larval development)

• Target Pests:

  • Spider mite eggs & larvae (Tetranychus spp., Panonychus ulmi)

  • Long residual activity (21-30 days)

  • Weak against adult mites

Fenpropathrin

• Chemical Class: Pyrethroid (IRAC Group 3A)

• Mode of Action: Sodium channel modulator (nerve toxin)

• Target Pests:

  • Adult spider mites (suppression)

  • Whiteflies, thrips, aphids

  • Lepidopteran pests (secondary control)

Best for:
Early-season mite prevention (Hexythiazox)
Knockdown of mites and secondary pests (Fenpropathrin)
Resistance management (two different modes of action)

 

2. Recommended Crops

• Fruits: Citrus, apples, grapes, strawberries

• Vegetables: Tomatoes, peppers, cucumbers

• Field Crops: Cotton, soybeans

• Ornamentals: Roses, nursery plants

(Always verify crop safety on product labels)

 

3. Application Guidelines

Dosage (Typical Rates)

Formulation	Rate per Hectare	Water Volume
Hexythiazox 10% EC	300-500 mL	500-1000 L
Fenpropathrin 10% EC	300-500 mL	500-1000 L
Premix Example (Hexythiazox 5% + Fenpropathrin 5% EC)	800-1200 mL	500-1000 L

Timing & Frequency

• Apply at first sign of mite presence (before webbing appears)

• Hexythiazox: Best applied preventively (early in season)

• Fenpropathrin: Provides quick knockdown of active infestations

• Reapply every 14-21 days if needed (max 2-3 applications/season)

Spray Method

• Use high-pressure sprayer (≥300 psi) for good coverage

• Ensure underside leaf application (critical for mite control)

• Add sticker/spreader for better retention

• Avoid spraying during peak sunlight hours

 

4. Advantages of the Mixture

 Broad-spectrum control (mites + secondary insect pests)
 Long residual activity (Hexythiazox protects for weeks)
 Resistance management (two distinct modes of action)

 

5. Precautions & Limitations

• Phytotoxicity Risk:

  • Fenpropathrin may cause leaf burn at high temps (>30°C)

  • Test on small area before full application

• Bee Toxicity:

  • Fenpropathrin is highly toxic to bees - apply at dusk/dawn

• Pre-Harvest Intervals (PHI):

  • Hexythiazox: 7-14 days (vegetables), 21-30 days (fruits)

  • Fenpropathrin: 3-7 days (vegetables), 14-21 days (fruits)

• Resistance Risk:

  • Rotate with non-pyrethroid miticides (e.g., etoxazole, spirodiclofen)

 

6. Example Commercial Formulations

• Standalone Products:

  • Hexythiazox 10% EC (e.g., Savey)

  • Fenpropathrin 10% EC (e.g., Danitol)

• Premix Example:

  • Hexythiazox 5% + Fenpropathrin 5% EC

    • Dose: 1.0-1.5 L/ha

    • REI: 24 hours

 

7. Resistance Management Strategy

Rotate with miticides from different IRAC groups:

• Group 20B (e.g., Cyenopyrafen)

• Group 23 (e.g., Spiromesifen)

• Group 25 (e.g., Bifenazate)

 

Final Notes

• Rainfastness: Hexythiazox (2-4 hours), Fenpropathrin (6-8 hours)

• Tank Mixing: Avoid alkaline products (may degrade Fenpropathrin)

• Storage: Keep in cool, dry place away from sunlight

For optimal results, combine with proper cultural practices like:

• Regular field monitoring

• Removal of heavily infested plant parts

• Maintaining proper irrigation to reduce plant stress
