- The Bacillus subtilis wettable powder is a loose powder with white to brown appearance and uniform composition, and should not be caked. The number of viable spores was 1000 × 108/g by counting method under microscope. Stability: sensitive to ultraviolet light, alkaline substances and fungicides have inhibitory effect on it, stable storage at room temperature for 2 years; Heat storage test:(54+2) storage at 14d, the reduction rate of the number of viable spores was measured to be less than or equal to 15%.
- The single dosage form includes Bacillus subtilis wettable powder (the number of viable spores is 1 billion/g) and Bacillus subtilis suspension Seed Coating Agent (the number of viable spores is 10000/mL): well 2.5%. 10 billion/mL Bacillus subtilis water, 1 billion/g Bacillus subtilis and Pseudomonas fluorescens can be wet powder.

Quantum 4000 - Preparation Method
Open Data Verified Data
Bacillus subtilis is a bacterial fungicide, which can inhibit a variety of pathogenic bacteria. Its mechanism of action is mainly through nutritional competition with a certain degree of site competition. The secretion of Bacillus sp. Has a certain inhibitory effect on some plant pathogens, but it is not the main inhibitory factor of plant pathogens. The field efficacy test results showed that the Bacillus subtilis WP had better control effect on cucumber powdery mildew, strawberry powdery mildew and gray mold. Dosage: 840~1260G/hm2 for cucumber powdery mildew (generally diluted with 50 ~ 60kg of water); 600~900g/hm2 for strawberry powdery mildew (generally diluted with 40 ~ 50kg of water); strawberry gray mold with 480~720g/hm2 (generally diluted with water 40 ~ 50kg). The method of use is a uniform spray. Beginning in the early stage of the disease, continuous spraying 2~3 times, usually 7 days interval spray 1 time,

Quantum 4000 - Application
Open Data Verified Data
- The Bacillus subtilis wettable powder has acute oral LD50>5000mg/kg and acute percutaneous LD50>2000mg/kg for rats, and has no irritation to rabbit skin and slight irritation to eyes; the sensitization rate of the skin sensitization test of the fat guinea pig was O, which was a weak sensitizer. In rats 90D subchronic feeding test, the maximum non-effective dose was 10 mg.kg-1.d-1; Mutagenicity test: the results of Ames test, micronucleus test of mouse bone marrow cells and chromosome aberration test of mouse testis cells were all negative; The results of pathogenicity test were non-pathogenic. The acute toxicity classification of the fungicide belongs to low toxicity. Low toxicity to fish, birds, bees and silkworm, bio-safety to the environment.
- it is preferable to seal and protect from light, and store at low temperature (about 15 ° C.).
