Molecular weight: 241.33
Melting point: 121-124°C
Physical and chemical property:
It is pink powder or yellow crystal, and it is easily dissolve in the water, activity higher than indoleacetic acid, it will be slow to decomposition under the strong light, stored under shading condition, and stable of the molecular structure.
Toxicity: acute oral LD50 in mice for 3160 mg/kg, on the skin LD50 in mice for 5000 mg/kg.
Function mechanism:
It is a kind of plant growth regulator for promote rooting.
1. Induced the formation of adventitious root crops, promote cell fission, break the seed dormancy.
2. It is the best regulator of rooting and strong seedling in the winter.
Function and characteristic:
1. After it become the potassium salt, its stability is stronger than Indole butyric acid, and soluble in water.
2. It can break the seed dormancy, and growth root and strong root.
3. Big and small trees, it is the most technical products for cutting and transplanting.
Usage:
1. Dipping method: 50-300ppm dipping cutting base for 6-24h.
2. Fast dipping: 500-1000ppm dipping cutting base for 5-8s.
3. Dipping powder method: After potassium indolyl butyric acid mixed with talcum powder, let the cutting soak, dip powder, cutting.
Flush fertilizer is 3-6g/mu, drip is 1-1.5g, seed dressing is 30kg seeds with 0.05g technical material.
