Using Paclobutrazol for Mangoes

TIPS ON USING PACLOBUTRAZOL AS MANGO TREE REGULATOR

By Felix B. Daray  ( Published in the Agriculture Magazine of the Manila Bulletin, April 2011)

When Paclobutrazol is not applied, it takes nine months for the leaves to mature and that’s the only time you can induce the mango trees for flowering. If not induced the tree flowers but does not bear much fruits.

Paclobutrtazol is applied two months after flushing. The leaves become dark green a few days after application. Two months latter, the mango tree is ready for induction. So if say, the tree flushed in February, apply paoclobutrazul in April. Induce in June and you’ll harvest by September when the price of mango is high up to December.
Here some tips on using Paclobutrazol:

Apply to trees 10 years old and up. Do not apply Paclobutrazol to mango trees below 10 years as these have soft branches, hence fruits cannot hold much fruits.

Select trees with many flushes. Do not apply Paclobutrazol to trees that have not flushed or to those with matured leaves.

Application ratio depends on the age of the tree, Being a mango grower for years, I have learned that the application ratio depends of the age of the tree. For 10 – 15 years old trees, I suggest an application ratio of 5 tbsp of Pclobutrazol to 2 liters of water per tree.

Apply to the base. Some mango growers spray Paclobutrazol solution to the leaves, but is more and practical to spray it to the base of the tree, so the chemical will not be washed out when it rains. Pour the solution on loosened soil 2 meters around the base of the tree Do not apply when the soil is very dry or if rain is shortly expected. If it did not rain a week after application, spray the base with water to facilitate further absorption.

Apply flower inducer after harvest. Since the leaves are mature, spray flower inducer for simultaneous flowering.

Do not induce trees after the second cropping. Some farmers induce for third cropping, but do not expect high yield. Rehabilitate the trees for a year or more. Spray newly opened flushes with insecticide to control leaf-eating insects. Mango trees are ready for another cropping after the second flushing and that’s when you can start another cycle of Paclobutrazol aplication.

I have taken all these tips and last December I harvested 9.5 tons of mangoes from my 2-hectare from Kibuaya, Hagonoy Davao del Sur. I sold my produce at P30 per kilo. It was my first “bumper harvest” and second cropping with Paclobutrazol application. Of my 150 mango trees, 75% fruited. And as of this writing, my trees have started to rejuvenate.

  2. vishal,thank your for reading my blog. It's simple to follow my tips above. After harvesting using Paclobutrazol, inducer for another cropping.

    So if say. the trees flush in January. Apply PAclubrazol in March. Induce for flowering in May. And you will harvest in August. Then induce after harvest. And by December you will have your second harvest.

  5. Vishal, After harvesting, spray fruit inducer if the trees have not started flushing. Dissolve 5 kilos of Kno3 per 200 liters of clean water. Then spray .

    1. Mr raju,
      last year i used paclobutrazol first time in my farm, and result was amazing. I used both branded " Cultar" and powder form of paclobutrazol. Both result was fantastic. So try it in your farm too. you will get good benifit from that.

  9. Paclobutrazol: Sometimes what you don't know can hurt you.

    paclobutrazol has been limited to growing ornamental plants.Because there are seemingly desirable effects paclobutrazol can have on your plants. Paclobutrazol is very effective at growing shorter, bushier plants and triggering earlier fruit sets with more pronounced flowering.

  10. vishal, good news that it works on indian varieties too. please provide how and when you used the pachlobutrazol. What are the results of second crop yields and any drain on plant health.

  19. Flowering and Fruiting in Mangoes in the Top End with Paclobutrazol

    The profitability of growing mango is influenced by
    two key factors:

    •Productivity, which consists of yield and quality.
    •Supply and demand which rule market prices.


    Top End mangoes are the earliest to reach domestic markets and therefore attract a premium price. However, as Queensland mangoes reach the
    market, prices fall steeply. Besides, the onset of the wet season increases the incidence of pests and diseases, which lower fruit quality. The manipulation of fruit maturity in favour of an early harvest would
    therefore be of great value to growers.

  22. Apply paclobutrazol for two successive cropping. After harvesting your first cropping, spray at once for induction.

  23. To kandasamay,
    Using paclobutrazol does not harm the trees. The content of paclobutrazol is purely fertilizer. It's like vitamins used by man.

    Thank u so much for sharing ur knowledge and experience on the application of
    Paclobutrazol on mangoes.
