- Reduced sunburn.
- Reduces fruit temperature.
- No need for additional copper spray.
- No need for additional stickers or wetters.
- Residue can be removed in the packhouse.

Sunshade is an organic product approved per European citation no. EC 834-2007.
Sunshade is a proprietary formulation of Kaolin and Copper Oxychloride developed by Delta Chemicals (Pty) Ltd. It contains a very fine silica-free kaolin, commonly used as a food additive and in cosmetics. Kaolin is considered safe for humans and the environment. This wettable powder adheres well to fruit and does NOT need any addition of wetters or stickers. When sprayed on fruit and vegetables, it forms a physical barrier to act against heat stress and sunburn. It also contains Copper Oxychloride which is used in the well known fungicide Demildex and therefore assists in the eradication of certain diseases.
It is important to apply Sunshade before the risk of sunburn occurs and hten, to maintain a fruit coverage. This usually means that fruit is sprayed every 14 days during the season. Standard spray can be used. A dilute suspension is made up and sprayed at a recommended dosage of 30kg per hectare, per 1000 litres of water.
Better Coverage For Superior Protection
Optimal particle size is a key factor in the oustanding performance of Sunshade. “Particle size” is a term which refers to the average diameter of the particles in the product. Best performance is attained from 1 to 2 micron particles.
The smaller the particle the greater the coverage and this factor governs performance and protecton indices. For horticultural coating agents the tenacity coefficient is a measure of the product’s ability to stick to the plant and hence, gives a strong guide to its resistance to weathering from rainfall or overhead irrigation.
