According to the National Association of Cocoa Exporters – Ecuador, Anecacao, only 0.1% of the total number of flowers produced by a cocoa tree are fertile. If in addition, unfavorable climatic conditions are given, the flower does not settle and falls. But the DISPER products were created to solve specific problems. We designed a trial that would evaluate the effectiveness of DISPER Bloom GS as a treatment for fruit development and setting,  to improve the viability of pollen, its germination and vitality to reach the ovary, the fertilization of the ovules and fruit setting as a result of a better pollination.

The trial was carried out in the province of Guayas (Ecuador), with cocoa cv. “EET 558”, in a planting frame of 3×3 m (1,100 plants / ha), on an area of ​​1 ha. It started in April 2017.

The applications of DISPER Bloom GS were made at doses of 0.5-1.0 kg / ha directed to the trunk during the flowering process. We made 6 applications because the cocoa flowering is staggered. The first of 1.0 kg / ha and then five of 0.5 kg / ha applied to the trunk. The supply of the treatment was monthly during the 6 months of flowering cycle beginning until the harvest, with a broth spending of 200 L / ha. The design of the experimental plots was completely done at random, with three repetitions per thesis.

In October 2017, just 6 months after the start of the trial and coinciding with the first harvest, the first evaluation was arranged. The plants treated with DISPER Bloom offered an average production of 47.32 fruits per plant, this is more than double of what the control plants offered which kept an average production of 23.33 fruits / plant.



Regarding the temporal evolution of the fruit development, the plants treated with our DISPER Bloom GS reached a higher level of fruit development earlier and kept it for a longer period.

Regarding the parameter total amount of flower and fruit abortions, the plants of the DISPER Bloom GS thesis had only 0.33 abortion of flowers / plant, while those of the control reported abortion of 1.67 flowers / plant. The results referring to fruit abortions in the initial phase were even more satisfactory because the plants treated with DISPER Bloom GS did not have abortions whilst the plants of the control aborted 7.67 fruits / plant.

Conclusions treatment for fruit development and setting:

DISPER Bloom stimulates the flowering and the fruit setting even in crops in which abortion rate is as high as cocoa.

  • Increases the number of fruits per treeIncreases production per tree.
  • The fruit development is more constant over time
  • Decreases the number of floral abortions
  • Decreases the number of abortions of fruits in the initial stage (cherelles)
