Note: Above weather information is summary of weather forecasting given in following websites,,,,, etc.

II.      a) Days after pruning: 149 days

      b) Expected growth stage of the crop: - Cane maturity and afterwards stage after foundation pruning


III.     Water management (Dr. A.K. Upadhyay)

Expected pan evaporation:  5 to 7 mm

Amount of irrigation advised

1.     The irrigation water application should be based upon the growth of the vines.  In case rain exceeds 5 mm on a given day, irrigation water application can be skipped for that day.  Generally, under wapsa (field capacity) condition of the soil, donot irrigate the vineyard.

2.     Most of the vineyards have already crossed cane maturity stage.  The irrigation water application should be such as to avoid new shoot growth as this may lead to development of disease and pests.  Emphasis should be to maintain existing leaf in healthy condition and avoid leaf fall till it is desired.  

3.     In many grape growing areas still, low rainfall has been received.  The salts might not have been leached sufficiently.  Wherever, sulphur / gypsum were used for removing sodium from exchange complex, there is need to flood the root zone.  In case water is available in canal/ well, flood the root zone to leach the salts.  Before flooding remove the mulch from the bunds.

Fruit pruning season:

1.     During shoot growth stage, apply irrigation through drip @ 6500 to 7000 L/ acre/ day for Pune, Nasik and Sangli region and for Solapur, Bijapur and Hyderabad, apply @ 8500 9800L/acre/day.

2.     In case vigour is more than desired, then reduce irrigation water application by half to 3250 - 3500 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.


Foundation pruning season:

1.     After Cane maturity stage, fertilizer application is over.  Look for the sodicity problems. Soil, petiole and water reports will give information on extent of buildup of sodicity in soil.  Apply gypsum to the soil for removal of sodium from the soil exchange complex.  In case of calcareous soils, use sulphur for similar purpose.  Gypsum/sulphur should be properly mixed in soil.  The soil should be moist.  After approx. 20 days adequate irrigation should be provided to leach sodium from the soil.

2.     Remove mulch applied during Foundation pruning and loosen the soil for improving movement of water through the root zone to reduce salts accumulated in the root zone.  Organic mulch can be mixed in the soil to improve the porosity of the soil.

Fruit pruning season:

1.     If soils are calcareous in nature, then apply 50 kg sulphur between the vines in the soil atleast 15-20 days before pruning. The sulphur should be properly mixed in the soil for improving its efficacy in taking care of calcium carbonates.  The efficacy of sulphur is improved if FYM/ Compost are applied along with sulphur and mixed in the soil.

2.     Apply FYM/ other organic sources including green manuring atleast 12-15 days before pruning.  Application of organics improves the nutrient and water retention in the root zone and reduces nutrient losses from the profile.

3.     In calcareous soil, if planning to add single super phosphate, mix with FYM and then apply.  This will improve phosphorus use efficiency as well as reduce the phosphorus fixation in calcareous soil. 

4.     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 @ 20 kg/ acre in two splits this week.  Depending upon the crop vigour, regulate nitrogen application.

5.     If sodicity problem is there, apply 10 kg Sulphate of potash per acre in 2 splits this week.




V. Requirement of growth regulators (Dr. S.D. Ramteke)  

If light rain may be the possibility, in this situation, drainage in the vineyard is must, however, if it is not available, try to drain out rain water from the vineyard.


VI. Canopy management (Dr. R.G. Somkuwar)

Pruned vineyard in established garden:

In the area of Indapur and Bori, fruit pruning is in progress. Under such gardens, the vines under different stage require attention in following way.

1)     Just pruned vineyards: The inoculum of major disease like downy mildew may be available on cordon and also on ground in the form of infected leaf. Hence, removal of these left out leaves should be given top priority. Spray of Bourdaux twice (0-6 days from fruit pruning) will help to check the disease under control.

2)     Removal of excess shoots immediately after the bunch emergence (during 14-16th days after fruit pruning) will help to maintain open canopy. First spray of GA3 at parrot green colour stage (18-20 days after fruit pruning) will help to achieve rachis elongation and increased rachis length.

3)     Removal of excess bunches during pre-bloom stage will help to maintain the source: sink relationship.

4)     Before the spray of PGR is undertaken, ensure the pH of spray solution.

5)     The grape growing region of Indapur and Bori is experiencing the hot and dry climate. Hence, avoid the spraying during hot sun.

Soil drenching with Trichoderma sp may be carried out




VII.    Insect and Mite management. (Dr. D.S. Yadav)



     Spraying of emamectin benzoate 5 SG @ 0.22 gram per litre water or fipronil 80 WG @ 0.06 gram per litre water is effective to manage caterpillars.

     Remove excess shoot to manage thrips populations.

     Vineyards may have higher mealybug infestation as well. However, increase in relative humidity will favour build-up of natural enemies and natural biological control of mealybugs. Therefore, avoid spraying broad spectrum insecticides. Use of insecticides for mealybug control should be avoided. Entomogenous fungus such as Metarhizium, Beauveria and Lecanicillium can be used for plant wash at 15 days interval to reduce mealybug populations. If, insecticide application seems inevitable, the only buprofezin 25 SC @ 1.25 ml/L water may be used for management of mealybugs as this insecticide does not harm beneficial organisms in the vineyard.

     Mite infestation may be observed on old leaves at some places. Spraying of sulphur 80 WDG @ 2.0 gram per litre water is effective to manage mites.

Crop advisory relevant to different places is prepared by experts, considering forecasted weather, crop growth stages in majority of vineyards and ground information on incidence of different conditions in different grape growing areas received from regular interaction with progressive grape growers. No claims are made on its correctness.
