Practical Protection for Valuable Table-Grape Crops
Unpredictable rainfall close to harvest can affect the quality and marketability of table grapes. Direct rain on berries may contribute to splitting, cracking, moisture damage and conditions that encourage bunch rot.
Polywrap grape covers form a protective overhead barrier above the vines. They help keep direct rainfall away from the canopy and fruit while still allowing natural light to reach the crop.
Our grape-cover film is suitable for commercial vineyards across South Africa, including the Western Cape, Northern Cape, Limpopo and other table-grape production regions.
Benefits of Using Grape Covers
Helps Protect Grapes from Direct Rainfall
The plastic cover intercepts rain before it reaches the berries, helping growers protect the crop during sensitive ripening and harvesting periods.
Helps Reduce Berry Cracking and Splitting
Sudden rainfall and moisture changes can place pressure on ripening berries. Keeping direct rain away from the fruit can help reduce the risk of weather-related cracking.
Supports a Drier Growing Environment
Grape covers help reduce direct wetting of the fruit and canopy. A drier environment around the bunches can help lower the conditions associated with bunch rot and certain moisture-related diseases.
Helps Preserve Fruit Appearance
By reducing direct exposure to rain and weather, grape covers can help protect the clean appearance and finish required for high-value table grapes.
Diffuses Harsh Direct Sunlight
Milky-white film allows light into the covered area while diffusing harsh direct sunlight. The effect will depend on the selected film specification, vineyard structure and installation.
Provides Greater Harvesting Control
Protecting the crop from unexpected rainfall can give growers more flexibility when planning harvesting, packing and labour requirements.
