Triacontanol (TRIA) is a plant growth regulator for many plants.It can be used as photosynthesis enhancer.When applied on plants, it can significantly increases the amount of chlorophyll in leaves, thereby improving the rate of photosynthesis.It can also increase the rate of cell growth,nitrogen fixation,enzymes activities,free aminoacids, reducing sugars,and soluble protein of plants.
Appearance…………………Pale white emulsion
Promote bud formation
Stimulate the formation of flowers & flowering shoots
Make stem and root stronger

1.3 Soil condition
Red clay soil, after years of improvement, with higher fertility, about pH 6. Citrus garden has entered the rich fruit period, production levels reached 3000kg per 667m2. Spraying herbicides in citrus garden, less weed.
1.4 Selected Crop and variety
Citrus, Wenzhou Satsuma precocious species, age of 12 years, planting specifications 4m×3m. Soil cultivation, fertilizer management and growth conditions are same for each test cell and is consistent with local agricultural production.
- Test design and arrangement dosage
2.1 Test design
Each test cell randomly arranged.The test included five treatments, repeated four times. There are 20 cells in total. 3 citrus trees per cell (36 square meters).
Treatment a: apply Dora Booster Triacontanol 0.2% ew at the rate of 1:2000, spray 160 litre of water per 667m2.
Treatment b:apply Dora Booster Triacontanol 0.2% ew at the rate of 1:3000, spray 160 litre of water per 667m2.
Treatment c:apply Dora Booster Triacontanol 0.2% ew at the rate of 1:4000, spray 160 litre of water per 667m2.
Treatment d: apply gibberellic acid crystalline powder at the rate of 1:33500,spray 160 litre of water per 667m2.
2.2 Mode of application dosage
2.2.1 Test time and frequency
Spray once during citrus flowering period (April. 24th), young fruit period (May.12th), fruit enlargement period (July.2nd), spray 3 times totally.
16 knapsack hand sprayer
Test citrus garden pest control is in conventional way, from April to September, a total of spraying insecticides, fungicides six times, the number of spray times, times, and dosage of each test cell is the same.
- Result and Analysis
3.1 citrus growing effect and significant difference between the measurement results as follows.
|Treatment||Flower bud||Crown height||Crown diameter||Branch mount||New shoot length|
1.Effect of each treatment was repeated four times . 2.Use “DMRT to do the significance of difference measurement . 3.Use letter method to compare the difference notability.
3.2 Fruit setting and yield increase difference between the measurement results as follows:
|Treatment||Fruit amount||Fruit setting rate||Single fruit weight||Single plant yield||Growth rate
4 Results and discussion
Apply 3 times of Dora Booster Triacontanol 0.2% ew during citrus flowering period, young fruit period, fruit enlargement period, which can significantly increase citrus fruit setting rate by 4-6%, and it also can promote fruit germination, benefits next year citrus crown formed and flower buds increased. It has good effect on citrus growth and yield increase, and is safe for crop, which can be widely used.
Spray Dora Booster Triacontanol 0.2% ew , dilute 2000-3000 times in citrus flowering period, young fruit period, fruit enlargement period. Spraying citrus trees should be uniform thorough spray, dosage is based on tree size.
