Entomopathogenic Fungal Acaricide is a bio-based crop protection active formulated with selected entomopathogenic fungal strains targeting spider mites and phytophagous mites across commercial agricultural operations. Manufactured through solid-state fermentation, this microbial acaricide provides chemical-free residue management while serving as a core tool for acaricide resistance mitigation programs.

Biological Mode of Action
Adhesion & Germination: Fungal conidia adhere to the insect cuticle and germinate under humid conditions, forming an appressorium.
Cuticular Penetration: Enzmatic secretion (chitinases, proteases, lipases) degrades the mite exoskeleton to enable structural entry.
Internal Proliferation: Hyphae invade the hemolymph, producing micro-mycotoxins that paralyze and destroy host tissue within 3–5 days.
Sporulation: Post-mortem hyphal growth emerges through the cuticle, dispersing new infective spores into the surrounding canopy.
Target Pests
Two-Spotted Spider Mite (Tetranychus urticae)
European Red Mite (Panonychus ulmi)
Citrus Red Mite (Panonychus citri)
Broad Mite (Polyphagotarsonemus latus)
Rust Mites (Eriophyidae family)
Crops & Applications
Greenhouse Vegetables (Tomato, Pepper, Cucumber): Applied via foliar spray during early mite infestation cycles to maintain zero chemical residue limits.
Fruit Orchards (Citrus, Apple, Grape): Tank-mixed with compatible adjuvants to control overwintering populations and adult mite outbreaks.
Berry Crops (Strawberry, Blueberry): Deployed pre-harvest to replace synthetic acaricides susceptible to maximum residue limit (MRL) rejections.
Ornamentals & Floriculture: Integrated into spray schedules to prevent foliar scarring and mitigate chemical phytotoxicity risks.

FAQ
Q: How does this microbial acaricide prevent pest resistance?
A: The multi-site physical penetration mechanism via enzymatic cuticle degradation prevents target mite populations from developing metabolic or target-site resistance commonly associated with synthetic chemical acaricides.
Q: What temperature and humidity conditions optimize field performance?
A: Optimal efficacy occurs between 20°C and 30°C with relative humidity above 60% during application. Thermal stability additives can be incorporated for hotter climates.
Q: Can this product be tank-mixed with conventional fungicides?
A: Microbial fungal acaricides should not be mixed directly with systemic chemical fungicides. A minimum 5-to-7-day interval between fungicide application and fungal acaricide treatment is recommended.
Q: What is the typical shelf life stability under standard warehousing?
A: When stored in sealed original packaging below 20°C, spore viability remains above 90% of the initial CFU rating for 12 months. Refrigerated storage at 4°C extends viability to 18 months.
Q: Is this product suitable for organic agricultural inputs?
A: The technical strain is produced without synthetic chemical additives, making it suitable for incorporation into certified organic inputs subject to local regulatory registration standards.
