Grape: make 500 dilution foliar spray on whole grape tree during color change period(2~4 weeks before grape harvest).
Apple: make 250 dilution foliar spray on whole apple tree at 35~42 days prior to harvest and again 7-14 days later.
Mixed with Brassinolide, the results is better.
Product | Application method | Dosage | Good Effects | Bad Effects |
Prohydrojasmon (PDJ) | Foliar spray | 500~800 dilution | Make fruit blush earlier and evenly;Advance maturity around 1~2 weeks;Increase sugar content in fruits;Enhance fruit resistance to environmental stress and disease | Not found |
Abscisic acid (s-ABA) | Fruit spray or dripin low concentration | 100~400 dilution | Make fruit blush earlier;Advance maturity around 1~2 weeks; | May cause leaf turn to yellow;May cause harm to grape fruit powder |
Ethephon | Foliar spray | 2000 dilution | Make fruit blush quicklyAdvance maturity around 1~2 weeks; | Incorrect dosage may cause soft fruit or falling fruit, storage time is short post harvest |

By combined spraying of gibberellin (GA) and prohydrojasmon (PDJ), the occurrence of peel puffing can be almost reduced by half. The optimum concentrations of GA and PDJ in the spray are 3.3 and 25 ppm.

Field Trial of Prohydrojasmon (PDJ) on pineapple, it is suggested to mix PDJ with Potassium fertilizer or amino acids, the result will be better.
Customer in Peru who completed trial of Prohydrojasmon (PDJ) on his grape farms, sent us the feedback. He said the color improvement is fantastic.

One company in Mexico already carried out trial on grapes and got good results, the technican said PDJ is the future.
