Late onset of monsoon by 15 days

Established plantations
- Mulch the basins & interspaces with green leaves.
- Spray lime 1% or kaolinite on foliage to reduce transpiration as well as heat load.
- Postpone new planting/gap filling
- Irrigate the crop @ 8–10 litres/day/vine (drip irrigation) or 50 litres/week/vine (hose irrigation)
- To prevent termite attack on live supports, drench the soil with chlorpyriphos 0.075% and spray on support up to 1 m height; repeat spray after 21 days if necessary
Very young plantations
- Mulch the basins & interspaces with green leaves/coir pith compost.
- Protect young vines by providing sufficient shade.
