SPRAYING GUIDE FOR
Day 1 - Flower Induction
concentration of KNO3 nitrate (2-3%) on young trees and
even on old trees during cold months. During dry season,
use lower dosage (1-2%). For 1% solution, 1 kg of KNO3
is needed to 100 liters of water. Stir the KNO3
whole canopy including the top portion of the tree. All
terminal buds should be thoroughly sprayed or wet with
the KNO3 solution in order to induce flowering.
Unsprayed bud will not flower or flush.
Note: If you
want to have 2-3 sets of fruiting in one tree, spray
only the portion of the tree where you want to have
fruits. You can schedule the other parts after a few
weeks so you will have continuous supply of fruits.
Day 7 - 25 - Flower Emergence to
disease control is very important on this stage, if left
uncontrolled will wipe out all the flower and fruits.
environment, anthracnose disease is prevalent; pests on
the other hand, are a lesser problem. To control
anthracnose, use systemic fungicide and to control mango
hopper and tip/twig borer, use insecticide.
season, diseases are lesser problems thus ordinary
fungicide can be used. Pests, on the other hand, will be
the major problem so learn to check the presence of
insects and use appropriate insecticide.
foliar fertilizer and growth enhancer, every 7-10 days
Day 25 - 35 - Full Bloom
This is the
time pollination takes place through the help of bees.
During this stage, do not spray insecticides or
fungicides so that the bees will not be killed.
Day 36 - 50 - Fruit Setting
mango hoppers, tip/twig borers and other harmful insects
should be controlled by spraying with appropriate
insecticide at 7-10 days interval.
and scabs attack the fruits which need to be sprayed
with fungicide at 7-10 days interval.
Day 51 - 110 Fruit Development -
presence of diseases such as scab, sooty mold and
insects like twig borer, fruit fly, mango pulp weevil,
capsid bug and mango seed borer - Spray with appropriate
chemicals when needed. Stop spraying 30 days
before ripening to avoid toxic residues on the fruits.
