Natural Brassinolide is a steroidal plant growth regulator.
Its function includes:
1. Promote the growth of plant to increase yield.
2. Raise the ratio of fruit bearing and increase the unit weight.
3. Enhance the resistance of the plant to drought and cold weather.
4.Enhance the immunity of the plant. Used in tissue culture,
regulate the differentiation of the tissue.

Applicable  Plant

Field Crop: wheat, rice, corn, bean, cotton
Vegetable and fruit: cucumber, tomato, chilli, celery, eggplant, strawberry,
and so on.
Fruit trees: grape, orange, sugarcane, sugar orange and so on.

Average increasing 6-9% after using Brassinolide in cereal crop. Especially using in flowering and seeding period of wheat, rice and corn, yield increasing is obvious evident.

Average increasing 6-9% after using Brassinolide in cereal crop. Especially using in flowering and seeding period of wheat, rice and corn, yield increasing is obvious evident.

spraying 0.01% brassinolide, 1000~2000 times diluent during the early flowering of wheat, using 1000 times diluent canbe increased more than 7% yield. 1500times can be increased 6.49%.

soaking seed or rice seedling bed period, using BR can make rice seedling strong, increase yield about 12%, the range 7.4%-21.5%.

Using 0.01% BR SL 300ML per hectare in tillering stage,early earing stage and full heading stage each time, can be inceased yield 9.65%-16.56%. Meanwhile it can shorten heading period, increase cold, wind and dew resistance. Its safe for rice.

Using 0.004% BR SL 1500times diluent soaking seed 24 hours before sowing the seeds. Take out and airing, then sow. This can increase seed germination, increase the length of root and single plant  raw weight, can also enhance the cold resistance of seedling.

Before tasseling stage, 0.04% SL 1.25-2.5ML or 0.01% EC 10-20mg per 0.07ha, add 50kg water, spray whole plant, can enhance photosynthesis, reduce ear bald  and increase kernels per spike.

Increase leaf chlorophyll content,  promote dry matter accumulation and growth of cotton.In the season of much rain, less sunshine etc. It can still help plant to keep high photosynthesis and leaf growth, enhance the resistanceIncrease boll stem number and boll weight, enhance cotton fibre and cotton seed enrichment degree, increase ginned cotton 4.25%-10.57% in normal year.Form trefoil stage or squaring stage, spray 0.05-0.1mg/kg BR one time every half a month. Continue use 2-3 times will be better.

1 soybean.Using 0.15% EC 10000 times diluent spraying on stem leaf can enhance lodging-resistance, reduce blighted grain, increase yield.

2 peanut.Using0.15%EC 7500-10000times diluent or 0.0002%soluble powder 40times diluent brassinolide in peanut needle under period can increase 10% yield.

3. sesameIf late sow the seed, poor soil, drought or less fertilizer, close and grow weakly, brassinolide can be used to promote the growth.

4. oilseed rapeSpray brassinolide one time in squaring period and flowering period, can increase more than 10% yield.

1.leaf vegetablesSpraying leaf during seedling stage, can promote growth, increase the amount of leaves; Same method of  harvest stage can prolong the harvest timereduce coarse fibre content,  improve taste. Spraying 2-3 times during seedling and growth period of leaf vegetable, can enlarge the leaves and can be increase 3.6%-10.1% yield.

2 root vegetable(potato, garlic, onion, radish etc. )Using 2-3 times during growing period, can enhance the resistance of disease and obviously increase the yield.

3. melon and fruit vegetable.Using 0.1mg/L BR during flowering and increase fruit period of tomato can increase weight, resist low temperature, and resist disease. Using BR in seedling stage of cucumber can resist 7-10°C night lower temperature. Keeping spraying 2 times during flowering and fruit period of pepper can be increase 7.86%-14.8% yield.

Spraying BR 0.01% EC 3000 times diluent before apple tree flowering and after flower fade, seedling and fruit swelling period each time, the apple tree stable and strong, no vain growth phenomenon, no side effect and can be mixed with pesticide. It was found that the leaf thickness increased 22.6%, green and luster, also enhance resistance after treatment by BR. Increase fruit setting rate about 20%, soluble solid content 3.4% and yield 13.1%. Good at fruit shape, color and luster.

Spray brassinolide during flowering period and the first physiological drop, can obviously increase the fruit setting rate 4.5%-5.2% and also increase the sweet of navel orange. Increase the yield, improve the quality.


no pesticide injury. Promote growth and have control effect of mosaic    disease. The effect rate can be more than 70%.Adding appropriate BR solution in culture during making inclining bacterial strains of Oyster mushroom and liquid strains, can promote growth of mycelium, shorten the period of strains culture, increase the yield, prolong the shelf life of strains etc.Spraying BR during planting aloe can  increase leaf length 2.3%-9.9%, blade width 24.3%-35.9%, thichness 72.2%-83.3%, in order to increase the yield and improve the quality.
