PINEYE™ Emulsion is a bio-based film forming surfactant. The Antitranspiration property protected your crops, flowers, fruits from sun damage, and reduced stomatal opening status and water loss.

Pineye Emulsion protect your crops, fruits, flowers for sun damage.


A research paper (Cuijing, 2011) stated that increasing temperatures can affect net crop revenue. When the temperature increased by 1°C, the total revenue of wheat in China decreased by 1.5% to 5.4% (You et al, 2005).

For example, the net revenue of this season’s rice crop in Huazhong decreased by 0.003% when the hours of sunlight increased by 10 hours per month. Meanwhile, the Northwest Area and Hua’nan saw an increase of 0.0030% to 0.0047%.

The net revenue of winter wheat increased by 0.03% in Hua’nan when the monthly hours of sunlight increased by 10 hours. However, this influence is relative, as the net revenue decreased by 0.09% in Huazhong and 0.03% in the Northwest Area.

Corn crops showed the same results. When the monthly hours of sunlight increased by 10 hours, the net revenue increased by 0.03% in Huazhong and the Northwest and Northeast areas while decreasing by 0.01% in Hua’nan.

Farmers lose money due to hot weather every year. In South Africa, 20% of Golden Delicious Apple crops and 40% of Granny Smith Apple crops are damaged by browning or necrosis on their surface, and are therefore not exported or sold (Engela Duvenage, 2014).

In China, in Hangzhou for example, the tea, hickory nut and lotus yields were significantly lower than last year, due to high temperatures and major storms (Xu Wenwen, 2014). When the temperature is over 35°C, young tea bushes will start to burn.

North America and Latin America have not escaped from the effects of the sun, and 40% of apple crops, including Fuji, Braeburn and Cripps Pink, have been lost due to sunburn. In Chile, farmers lose about 13.5% of their crops, or US$100 million, every year (Dr.Jose Antonio Yuri).

UV (ultraviolet) radiation is responsible for the damage.

Sunburn on Your Crops, Flowers and Fruits

Sun damage will causes the sunburn, sunburn browning and necrotic.


Three types of sunburn have been identified in apples (Schrader et al, 2011). Sunburn Necrosis is solely caused by high fruit surface temperature and appears as a necrotic spot on the sun-exposed part of fruit while on the tree. ( Graeme Thomson, 2014 )

Sunburn Browning is caused by joint exposure to high fruit surface temperatures (46°C to 49°C, depending on the cultivar) and ultraviolet-B, but does not result in cell death.

Photo-oxidative Sunburn requires visible light and affects shaded apples that are suddenly exposed to solar radiation. Initially affected areas of the skin appear bleached and later become necrotic.

PINEYE™, Di-1-p-menthene,

Di-1-p-menthene ( CAS 34363-01-4 ) is a key ingredient of PINEYE™ Emulsion, a terpene polymer prepared by pine oleoresin. The formulation is non-ionic and non-toxic and provides a physical barrier against fungi and diseases on the surface of your crops. It also prevents the premature falling of fruits and improves the shelf life of harvested fruits.

When PINEYE™ Emulsion is sprayed on plant leaves or fruit surfaces, it creates a soft, elastic, sticky and transparent film. The film is partly breathable, locks water vapor on the surface, and decreases the amount of bio-pesticides that will wash away during irrigation or rainfall erosion. Its key ingredients are also compatible with bio-pesticide activity.

PINEYE™ Emulsion is a sticky surfactant adjuvant that can be applied pre-mixed in the wetting formulation or added to the spray tank, to improve the performance of bio-pesticides. The sticky and anti-transpiring properties will increase the adhesion and wetting of biopesticides on plant surfaces. If you choose the right adjuvant, PINEYE™ may reduce or eliminate spray application problems and the effects of environmental degrading factors, improving the overall efficiency of bio-pesticides.
