II. Water management (Dr. A.K.
Upadhyay & Yukti Verma)
A)
Days after fruit pruning : 49 days
B) Pan
evaporation: 4 to 5 mm
Amount of irrigation advised:
1.
In case soil is under wapsa (field
capacity) condition, donot irrigate the vineyard.
2.
During shoot growth stage (Fruit
pruning season), apply irrigation through drip @ 6800-8500 L/
acre/ day for all grape growing regions. In case vigour is
more than desired, then reduce irrigation water application by half to 3400 -
4300 L/ acre and still if growth is more, stop the irrigation till such time the
growth is brought under control and then start irrigation.
3.
Practice mulching to keep the bunds
moistened. This will reduce the salinity build up in the root zone due to
evaporation of the moisture from the surface of the bund.
4.
From flowering to fruit setting,
apply irrigation through drip upto 3000 L/ acre/ day. Vigour
needs to be controlled.
5.
During Berry development stage, apply
irrigation through drip @ 6800-8500 L/ acre/ day for all grape growing regions.
Nutrient management
1.
Due to continuous sprays the leaf
will not look healthy, need based sprays should be followed as the leaf health
is bound to affect the photosynthate formation. This will
impact bunch development.
Shoot Growth stage
1.
Based upon the soil test value,
during shoot growth stage apply urea @ 15kg / acre this week in two splits.
If the soil is calcareous, instead of urea apply ammonium sulphate @ 25
kg/ acre in three splits this week. Depending upon the crop
vigour, regulate nitrogen application.
2.
If sodicity problem is there, apply
10 kg Sulphate of potash per acre in 2 splits this week.
3.
Until and unless leaves are fully
developed donot go for any foliar application of nutrients. It will be lead to
wastage of spray.
4.
The quantity of nutrients to be
applied through foliar, depends upon canopy size.
5.
If the crop is between 5 leaf to
prebloom stage, apply Zinc sulphate and Ferrous sulphate @ 15 kg/ acre based
upon soil test value. Boron application should be carried out
only if soil test value indicates low levels and the irrigation water does not
contain boron. If during foundation puning, the petiole test
stated that boron was deficient then apply boron @ 1.5 kg to 5 kg depending upon
the soil test value. Apply one kg boron at a time.
6.
Apply 15 kg Magnesium sulphate per
acre in two splits.
7.
If soils are calcareous, spray Sulphate of potash and
Magnesium sulphate @ 2-3g/L depending upon leaf age during prebloom stage.
Flowering to setting stage:
1.
Donot apply any nitrogen based
fertilizer just before Flowering to Setting stage to avoid problems of kooj
(inflorescence necrosis).
2.
Apply 3-4 kg Phosphoric acid in two
to three splits this week. Remember that the pH of the
irrigation water should be near 6.0. OR apply SSP @ 125kg/acre as basal
application. SSP should be mixed with FYM/Compost before
application to minimize phosphorus fixation.
3.
If SOP not applied, then apply 15 kg
SOP in case low temperature and cloudy conditions forecasted during flowering
stage.
4.
Petiole nutrient testing:
At 70% capfall stage, petiole samples should be taken for nutrient
analysis. The leaf opposite the bunch should be removed for sampling.
Berry Development stage:
1.
After Berry setting, continue
initially with Phosphoric acid application @ 2 kg followed by 5 kg 12-61-0/acre.
2.
If the berry size is from 2-4mm,
spray calcium @ 2g Calcium Chloride / Calcium Nitrate per litre.
Target sprays immediately after GA application (preferably next day) for
better absorption.
3.
If the berry size is from 5-8mm,
spray calcium @ 2g Calcium Chloride / Calcium Nitrate per litre.
Target sprays immediately after GA application (preferably next day) for
better absorption.
4.
After 8-10 mm berry size, start
application of nitrogen in the form of ammonium sulphate @ 25kg /acre in 4
splits in calcareous soil and as urea @ 15 kg/acre in other soils in 3 splits.
Follow this up with Sulphate of potash or 0-0-50 @ 25 kg/ acre in 3-4
splits for next two weeks.
III. Requirement of growth regulators
(Dr. S.D. Ramteke)
-
NIL
IV. Canopy Management (Dr.
R.G.Somkuwar)
Following practices are suggested during
the coming week
1.
Due to continuous rainfall, the
moisture is more. Hence, the root activity will be slow. The application of
fertilizer through spray can be taken.
2.
Under the condition of vigorous
growth, the cane maturity may get delayed. Hence, shoot pinching, removal
of side shoots is suggested.
3.
Under delayed cane maturity, fruit
pruning should be delayed depending upon pith color.
4.
Application of potash
through spray and soil can be initiated to enhance cane maturity.
5.
Bud testing should be
given priority before fruit pruning. This will avoid errors in pruning.
6.
Before the fruit
pruning, disease control through biological means will support after pruning.
7.
Opening small trench between two rows
will help to remove the water from root zone.
8.
Rainfall during bud sprouting stage
may lead to conversion of bunch into tendril. To avoid this, vigor need to
be controlled.
9.
Application of cytokinin based PGR
and potassium can help to control fillage.
10. Removal of infected
leaves at the time of fruit pruning should be given priority.
11. Application of
hydrogen cyanamide should be based on cane diameter and temperature in the
vineyard. Higher cane thickness will require higher dose while high
temperature in the vineyard will require lower dose.
12.
Before fruit pruning, the cane should
have complete bud swelling. This will help for uniform and ealy bud
sprouts
V. Disease management (Dr. Sujoy
Saha)

|
49 |
Moderate |
low |
High |
Bacterial spot- moderate to high’ Rust-moderate |
Rains are predicted in most of the grape
growing areas. At ponga stage application of copper fungicides may be done to
give a protection against downy mildew. At 5-7 leaf stage application of
Dimethomorph@1g/L+mancozeb 75WP@2g/L or Iprovalicarb+propineb @ 2.25g/L or
Mandipropamid@ 0.8g/L or Dimethomorph +ametoctradin@0.8g/L or Amisulbrom @ 0.375
ml/L should be done in absence of rain to protect against
downy mildew. If leaves are wet, dusting of Mancozeb @3-5 kg/ acre may be done.
Due to continuous rains in most of the areas anthracnose and bacterial spot may
be incident in a moderate scale. Thiophenate methyl/carbendazim@1g/L should be
given for anthracnose control. An application of Kasugamycin+Copper oxychloride
may be given @ 0.75g/l for the management of both bacterial spot and
anthracnose, but specifically it should be more effective against bacterial
spot. Streptocycline should NOT be applied for the control of bacterial
diseases. Powdery mildew may be disseminated by the rain
splashes and initial symptoms may be observed as soon as the rain stops.
Application of triazoles like hexaconazole or difenoconazole will control
powdery mildew and additional protection against anthracnose will be obtained as
well. Foliar application of Trichoderma @ 2-3g/ml should be given during this
time to get a control against anthracnose and downy mildew. No mixing of
fungicides and biocontrol agents should be done. For any foliar spray,
silicon-based adjuvant should be used.
VI.
Insect and Mite management. (Dr. D.S. Yadav)
Fruit pruning growth stage: Active
shoot growth stage
·
Flea beetle infestation may be high during
this period. For flea beetle management, remove weeds from inside and around the
vineyards. Harrowing may be done in inter row space. Then give soil drenching
with clothianidin 50 WDG @ 200 gram per acre in the root zone to kill flea
beetle grubs in the soil. Thereafter, foliar application of lambda cyhalothrin
4.9 CS @ 200 ml per acre or imidacloprid 17.8 SL @ 160 ml per acre or fipronil
80 WG @ 25 g per acre or spinosad 45 SC @ 100 ml per acre may be given. The
foliar spray may preferably to give at night.
·
Incidences of new species of stem
borer (red colour larva) may be noticed under bark in Sangali, Solapur, Nashik,
Pune, Bijapur grape areas. Remove the loose bark and give good plant wash mainly
targeting cordons and main trunk with entomogenous fungi, Metarhizium
spp. @ 3-5 ml/L water (water volume 1.5 litres per plant).
