Many growers those are specialized in planting mango in the Mekong River Delta provinces such as Dong Thap, Tien Giang,
Hau Giang, An Giang ... today already know how to use regulatory chemicals of Paclobutrazol and some foliar fertilizers containing much
P and K to treat off-season flowering mango , the main purpose is to sell a higher price in order to increase profits.
We hope this article that will help farmers and mango growers understand more about fertilizers and chemicals of
the Saigon Plant Protection Joint Stock Company , simultaneously . apply it into off-season flowering treatment
process on mango in the most effective way .
APPROPRIATE PHASE OF YOUNG LEAVES TO TREAT WITH SAIGON P1 ON MANGO
I. TREATMENT WAY OF SAIGON-P1 ON MANGO :
1. Use a wire brush or old blade scraping layers of lichen, moss,
mouldy flakes sticking around the trunk 30cm from the ground upwards.
2. Use scoop or hoe, shovel to make water holding trench under the ground ,
to be closed the foot of mango plant
3. Dilute product depending on the canopy diameter 5-10 liters of water and spray it onto the trunk of about 50cm high ,
let product flow down to the foof and remain in the trench .
4. Depend on the variety, canopy diameter, plant age ... to calculate the amount of treated product. Averagely ,
1-kg can of SAIGON-P1 is treated 15 feet of mango plants of which is over 15 years old (about 65g / foot )
or 20 feet of mango plants of which is under 15 years old (50G / foot).
NOTE:
- After pouring
SAIGON P1, need to water and keep moist continuously for 2-3 weeks in order to increase product absorbing efficiency.
- Do not treat on stunted plants , poor growth or when their leaves were too old.
- Do not treatover 3 years consecutively , need a rest for 1-2 years for caring , adequate fertilizing for plants to recover.
- 20-30 days after treating
SAIGON-P1, spray Hi tech foliar fertilizer MKP (0-52-34) at concentration of 0.5-1.0% (0,5-1kg / 100 litre of water) 2 times ,
7-10 days apart to stimulate flower bud forming.
- Next, approximately 60-75 days after treating
SAIGON-P1, is necessary to spray MULTI-K 13-0-46 (KNO
3)
2 times , 7 days apart ( the first : concentration of 2%, the second : concentration of 1%) to break dormancy, stimulate flowering simultaneously.
TWO TYPES OF HI TECH FOLIAR FERTILIZERS USED FOR SPRAY AFTER HAVING TREATED WITH SAIGON P1 AIM AT HELPING MANGO TO FORM FLOWER BUD AND SIMULTANEOUS FLOWERING
- 20-30 days: spray foliar fertilizer of MKP (0-52 - 34)
- 60-75 days: spray foliar fertilizer of Muti-K (13-0 -46)
I SUMMARY OF MANGO CONTROL STEPS IN OFF-SEASON FLOWERING
1. Care and foster plant after harvest
- Prune off branches ,form clear canopy ,stimulate plant in peeping new shoots concentratively
- Put down fertilizer helping plant in peeping bud plumply and contratively aim at flowering and better anchoring fruit later .
It can be used NPK 15-15-15 along with organic fertilizer 10-15 kg / plant. Also, depending on the status of plant growth and previous crop yield that we apply fertilizer accordingly.
- Water helping plant in well- absorbed fertilizer , and fast peeping bud .
2. The first peeping of tender leaves
- If bud does not develop well (due to insufficient fertilizing, untimely manner) as a shortness, weakness to spray additional foliar fertilizer to give good bud development.
- Spray preventive pesticide for bud damaging pests, especially anthracnose, leaf eating hoppers and worms, aphids and thrips.
3.The second peeping of tender leaves
- After peeping tender leaves 15-20 days, pouring
SAIGON-P1 (Paclobutrazol).
- Care plant as same as the first peeping of tender leaves
4. Paclobutrazol treated (SAIGON P1)
- Dosage: 1-2 g of concentration / 1-m -diameter canopy of mango .
- Young plant also is treated less than full mature one.
- Vigorous plant , exuberant leaves is treated more chemicals than stunted one.
- Hardly flowering variety such as Hoa Loc mango, varieties of Pal-củn-xị or ĐT15( Thai mango ) with more chemicals to make them in easy flowering .
- Do not treat with flowering on plant that is too weakened due to too much yield in previous
year or newly fruit giving plant for 1-2 years .
- How to treat: dilute designed chemicals based on mango canopy diameter with 5-10 liters of clean water , directly pouring into the foot with availably dug trench .
- Irrigate water to keep moist for 3 weeks in order that plant easily absorbs product .
5. Stimulate the flower bud peeping after pouring Paclobutrazol (SAIGON P1)
- 20-30 days after treating with Paclobtrazol, spray MKP foliar fertilizer (0-52-34) at a concentration of 0.5-1.0% (0.5-1kg / 100 litre of water) 2 times, each time with 7 -10 days apart to stimulate flower bud
forming .
- 60-75 days spray MULTI-K foliar fertilizer (13-0-46) at a concentration of 2% in order to stimulate the flower bud forming ( it must stop pouring 15 days before spraying MULTI-K)
- 7-10 days later , 2 nd spraying MULTI-K at a concentration of 1%.
