Most grape growing areas will have partly cloudy conditions after Tue. The minimum temperature in most areas now gradually rising above 15-20oC, and in Nasik area it may drop again below 10oC after sun. Maximum temperature in most areas will come close to 30oC or more. Especially on Tue. It may reach in some areas up to 33oC which may lead to sudden rains. The diurnal variation is likely to increase more than 20oC in Nasik and Pune area. For vineyards where veraison is in progress, there are good chances of development of Pink berry. Flood irrigation will increase night temperatures, while covering bunches with paper will also give protection from rapid temperature changes and direct exposure to light. · Vineyards where flood irrigation is given may get higher risk of powdery mildew and measures to control powdery mildew will be a priority for coming week. · Vineyards at about 90 days after fruit pruning can be given one spray of myclobutanil 0.4 g / L just before covering the grapes with paper bags. · Vineyards more than 100 days after fruit pruning spray of Sulphur 80WDG, 1.5 to 2.0 g / L can be given. Doses of sulphur should be based on vineyard temperature. If the temperature is low highest dose should be given. · Use of sulphur is also useful for control of mites. In vineyards were rains are received on Tue. Due to increase in RH chances of powdery mildew will be more. Vineyards close to open rocky terrenes have good chances of hail storm. Vineyards with such history can protect their vineyards with erecting shade nets / Sarees etc. |

पुणे, सांगली, सोलापुर और बीजापुर अंगूर क्षेत्रों मेँ फसल अवस्था और मौसम स्थितियां, माइट और मिलिबग विकास के लिए उपयुक्त हैं। परंतु, बारिश होने की परस्थिति में माइट की संख्या में अल्पकालिक कमी आ सकती है । नासिक क्षेत्र मेँ न्यूनतम तापमान में कमी के कारण, माइट और मिलिबग के विकास में कमी आ सकती है। माइट के नियंत्रण के लिए गन्धक 80 डब्लूडीजी @ 1.5-2.0 ग्राम प्रति लिटर पानी (पी॰ एच॰ आइ॰ 15 दिन) अथवा फेनपायरोक्सिमेट 5 एससी @ 1.5 मिलि प्रति लिटर पानी (पी॰ एच॰ आइ॰ 60 दिन) का प्रयोग किया जा सकता है। मिलिबग के नियंत्रण के लिए बुप्रोफेज़िन 25 एससी @ 1.25 मिलि प्रति लिटर पानी (पी॰ एच॰ आइ॰ 40 दिन) का स्पॉट एप्लिकेशन किया जा सकता है। |

The crop stage and weather conditions are favourable for mite and mealybug development in Pune, Sangli, Solapur and Bijapur areas of grapes. However, temporary reduction in mite population may be noticed in case of rains. Decrease in minimum temperature in Nashik and Pune regions may halt development of mites and mealybugs. Sulphur 80 WDG @ 1.5 -2.0 g/L (PHI 15 days) or fenpyroximate 5 SC @ 1.5 ml/L (PHI 60 days) water can be used where mite infestation is noticed. For the management of mealybugs, spot application of Buprofezin 25 SC @ 1.25 ml/L water can be given while maintaining the pre harvest interval of 40 days.
