Acute percutaneous toxicity for rat, LD*0 >***0mg/Kg. Ames test indicates no mutagenicity. Bioactivity and application: Its bioactivity, application and scope are similar to those mentioned as above for **-brassinolide. But its effect is better than **-brassinolide (around 2 to 5 more times) Applying to wheat, rice, corn, soybean and peanut: 1).Spraying BR**1 on wheat and rice plant, **7days later, the chlorophyll can be produced more in the plant, which can promote the photosynthesis to produce more nutrition and dry substances, and 7 days later the amount of root increase, and root grow deeper into the soil, which make plant get more water and nutrition and resist drought and waterlog better. Also the length of segment of base part stem decrease. The plant get a better ability of lodging resistance and yield increases about *0%. 2) .Spraying on corn during pre-female inflorescence emerging stage once and need not use any other growth hormone. 3).Can increase the disease resistance ability of peanut and soybean and augment number of legume, also can realize multi-legume The effect is very obvious. Applying to vegetable: Spraying on leaf-vegetables, **5 da
