Pests of Fruit Trees (Citrus, Banana, Mango, Pomegranate and Sapota)
Management practices
x
The field must be kept weed free and clean. Follow either hand weeding/
harrowing till 5 months after planting or use herbicide- glyphosate 7-10
ml/ litre of water + 25 g of urea or ammonium sulphate/ tank or by
intercropping with cowpea.
x
While planting, optimum/ recommended spacing (1.6 m X 1.6 m) must
be followed.
x
Provide adequate drainage facility whenever it is required.
x
Apply only the recommended dose of fertilizer - N, P, K g/ plant (200:40:400)
as per the schedule + 25g azospirilium + 25 g phosphorus solublizing
bacteria. Application of Neem cake @ 0.5 to 1 kg/plant may also be applied.
Potash can be applied 10 to 20% more. Micronutrient mixture 10 g/plant in
3rd month and 5th month after planting must be applied.
x
Remove disease infected leaves or part of leaves & destroy it outside the
orchard.
x
No dried leaves should be hanging around the plant.
x
The following pesticides may be applied as soon as the symptom appears
on the leaves. The interval between two sprays may be 20 to 25 days. The
fungicide requirement for a litre of a water is as follows.
a.
Mineral oil 10 ml + propiconazole 0.1% (1ml per litre of water).
b.
Mineral oil 10 ml + carbendazim 0.1% (1g per litre of water).
c.
Mineral oil 10 ml + tridemorph 0.1% (1g per litre of water).

Change flower regulation time from rainy to winter season.
Maintain orchard sanitation by removing plant debris, pruning of dead
dry branches, drenching of ground with 2.5% bleaching powder (33.3%Cl)
@25Kg/1000 liter water/ha and sterilization of pruning tools with 2.5%
sodium hydroxide.
Sprays with suitable chemicals at recommended doses, starting from
flowering at 07-14 days depending up on season and nature (systemic/
non systemic) of fungicides give good control.

Take precautionary measures/preventive sprays 10 days before and soon
after the rains.
Leaf and fruit spots as well as rots caused by different fungal pathogens are
effectively managed by the sprays of carbendazim (0.2%), propiconazole
(0.1%), thiophanate methyl (0.15%), mancozeb (0.2%), difenconzole 25
EC (0.05%), captan (0.2%), benomyl (0.2%), ziram (0.25%), Bordeaux
mixture (0.5-1%) and copper oxychloride (0.25%).
Combination treatments of carbendazim (0.1%) + mancozeb (0.2%) and
benomyl (0.1%)+ mancozeb (0.2%) also improve fruit quality and yield.
Rot of pomegranate caused by C.gloeosporioide can be effectively checked
with a combination of tricyclazole 18%+mancozeb 62% WP @2.5g/l.

Second at panicle initiation stage with quinalphos 25% 20 ml or carbaryl
50% 20 gm or profenophos 50% 10 ml per 10 lit. of water. Subsequent
sprays with imidachloprid 17.8% 3 ml or clothianidin 50% (WDG) 1.2
gm or thiamethoxam 25% (WDG) 1 gm or triazophos 40% 10 ml or
phenthoate 50% 20 ml or diamethoate 30% 10 ml or deltamethrin 1% +
triazophos 35% 10 ml or Lambda cyhalothrin 5% 6 ml per 10 lit. of water.

Pests of Fruit Trees (Citrus, Banana, Mango, Pomegranate and Sapota)
Mealybug (Drosicha mangiferae)
In India, it is widely distributed along the Indo-gangetic plains and found in
Punjab, Uttar Pradesh, Bihar and Delhi causes severe damage to mango crop. It
attacks almost all the plant parts.
Symptoms
x
x
x
Pinkish nymphs and adult mealy bugs are
present on leaves, inflorescence, branches,
fruits and fruit stalk.
The nymphs of this pest suck sap from leaves
and inflorescence causing dryness leading to
flower drop and negligible fruit set.
They also secrete honey dew which gives rise
to sooty mold attack.
