In most grape areas cloudy conditions will continue and intermittent light rains are likely. Wherever, it rains more downy mildew incidence is likely flare-up. While in areas where only cloudy conditions prevail powdery mildew will dominate.

In most grape areas presence of downy mildew was reported during last week. Therefore for better control of downy mildew systemic fungicides (Phenamidone + mancozeb 2.5 g / L, (Dimethomorph 1.0 g + metiram 2.0 g )/L, Iprovalicarb + propineb 3.0 g / L, Cymoxanil + mancozeb 3.0 g / L, Pyraclostrobin + metiram 1.75 g / L) are strongly, suggested.

Wherever   3-4 sprays of copper fungicides (0.5% Bordeaux Mixture, or Copper hydroxide 1.5 to 2.0 g / L, or COC 2.5 to 3.0 g / L.) were given and outbreak of downy mildew was not seen,  additional spray of  copper fungicides should be given immediately. Sulphur 2.0 g / L may also be mixed with above mentioned fungicides to reduce the infection of powdery mildew.

For the control of powdery mildew one spray of systemic fungicides (hexaconazole 5EC 1.0 ml / L, or Flusilazole 40EC, 0.125 ml / L, or Tridemefon 25WP 1.0 g / l, or Myclobutanil 10WP 0.4 g / L, or Penconazole 10EC, 1.0 ml / L) may be sprayed.

In case if fungicides such as azoxystrobin 23SC 0.5 ml / L or Krisoxin methyl 0.6 ml / L have been used for the control of downy mildew, additional spray for powdery mildew control may not be needed.

Population of thrips, mites and mealybug will remain low at most grape growing areas. Excess shoot growth will appear after recent rains. On this new growth, thrips population may increase. Remove the excess growth and side shoots as these are favored by thrips. Even though, if more than 5-7 thrips/shoot/vine are noticed then application of fipronil 5 SC @ 0.80 ml per liter or emamectin benzoate 5 SG @ 0.22 g per liter or spinosad 45 SC @ 0.25 ml/L of water is effective.

Flea and chafer beetle adults start emerging and defoliate the plants during this period. Keep the vineyard free from weeds and if 2-3 beetles per plant are noticed then application of imidacloprid 200 SL @ 0.3 ml/l or lambda cyhalothrin 5 EC @ 0.5 ml/l water is effective.

The places where stem borer is a problem, this is the period for emergence of adult beetles and egg-laying. The beetles lay eggs in cracks and crevices of bark of stems and cordons. Stem borer grub will start hatching from eggs laid in previous week and bore into the stem and cordons. The rains will make the bark loose and easy to remove, therefore remove the loose bark and wash the stem and cordons with chlorpyriphos 20 EC @ 2 ml/L water. It will reduce mealybug population and egg-laying by stem borer.
