Features Of Baolai PT-BIO 900 Fungicide

  1. Broad-spectrum activity against key fungal pathogens including Botrytis, Alternaria, and Fusarium species.

  2. Biodegradable formulation with low environmental persistence and favorable toxicological profile for integrated pest management (IPM) programs.

  3. Non-phytotoxic to sensitive crops when applied at recommended rates, supporting consistent yield and quality.

  4. Compatible with most conventional agrochemicals and biologicals, enabling flexible tank-mixing options.

  5. Stable under standard storage conditions (15–30°C) and retains efficacy across a wide pH range (5.0–7.5).

Typical Applications Of Baolai PT-BIO 900 Fungicide

  1. Fruit orchards — particularly apple, grapevine, and strawberry production systems.

  2. Leafy vegetable cultivation — including lettuce, spinach, and kale under protected and open-field conditions.

  3. Greenhouse ornamental crops — such as roses, gerberas, and chrysanthemums.

  4. Seed treatment for vegetable and cereal crops to suppress soil-borne fungal inoculum.

  5. Post-harvest protection of stored fruits and vegetables during transit and cold storage.

Baolai PT-BIO 900 Fungicide – Frequently Asked Questions (FAQ)

Q1: What types of fungi does Baolai PT-BIO 900 effectively control?

A: Baolai PT-BIO 900 is formulated to provide broad-spectrum activity against common spoilage and pathogenic fungi in industrial systems, including Aspergillus, Penicillium, Cladosporium, and yeasts such as Candida and Saccharomyces species. Its efficacy is particularly notable in water-based formulations and high-humidity environments where microbial growth is a persistent concern.


Q2: Is Baolai PT-BIO 900 compatible with common industrial surfactants and polymers?

A: Yes — Baolai PT-BIO 900 demonstrates good compatibility with anionic, nonionic, and amphoteric surfactants, as well as with common thickeners (e.g., cellulose derivatives, associative polyacrylates) and film-forming polymers used in coatings, adhesives, and personal care emulsions. Compatibility testing under actual formulation conditions is still recommended to confirm stability and performance.


Q3: How should Baolai PT-BIO 900 be incorporated into formulations?

A: It is typically added during the cool-down phase or post-emulsification stage to avoid thermal degradation. Due to its liquid form and water-miscible nature, it disperses readily without requiring solubilizers. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight, adjusted based on challenge level and system pH.


Q4: Does Baolai PT-BIO 900 require pH adjustment for optimal performance?

A: Baolai PT-BIO 900 remains effective across a wide pH range (approximately 4.0–10.0), with peak stability and antifungal activity observed between pH 5.5 and 8.5. Significant deviations outside this range may affect long-term shelf-life or microbial kill kinetics, so monitoring and maintaining appropriate pH is advised.
