“…The effectiveness of Kaolin in reducing sunburn in most cultivars and regions may be more strongly ascribed to the reduction in harmful radiation reaching the fruit surface than to the reductions in surface temperature (Gindaba and Wand, 2005), although the latter would lower the threshold for radiation damage. The same results were found by (Schupp et al, 2002) on apple. Aly et al, (2010) reported that kaolin clay particle film produced labeled reduced in sunburn percentages.…”

“…However, Showler (2002) did not fi nd evidence of a shade response in cotton when particle treatments were used, nor did he demonstrate an increase in cotton lint yield associated with PKPF treatments. Schupp et al, (2002) found that a PKPF reduced fruit size, red color, and sunburn in 'Fujiʼ apple in Idaho; while in New York, early season applications had no effect on fruit size or color in 'Honeycrispʼ, but late season applications reduced fruit size and red color. Jifon and Syvertsen (2003) demonstrated with citrus leaves that PKPF applications increased leaf refl ectance, reduced midday leaf temperatures and leaf-to-air vapor pressure differences (VPD) compared to watersprayed control leaves.…”

Processed-kaolin particle films (PKPFs) are used commercially in large quantities on horticultural crops to repel insects, and reduce heat stress and solar injury of fruit. Our studies determined the effect of two processed-mineral particle film materials (kaolin and calcium carbonate), on whole plant carbon assimilation, water use efficiency, yield, mean fruit weight and quality in `Empire' apple [(Malus ×sylvestris (L.) Mill var. domestica (Borkh Mansf.))] over a four-year period. The application of a PKPF reduced canopy temperature, and probably reduced environmental stress, resulting in increased mean fruit weight and red color in two of the four years of the study. Whole canopy carbon assimilation studies indicated increased carbon assimilation only under conditions of high air temperature. The PKPF sprayed leaves also had reduced water use efficiency; likely due to increased stomatal conductance associated with reduced leaf temperature. Calcium carbonate had none of the positive effects of PKPF and reflected more photosynthetically active radiation (PAR) than the PKPF.

“…One way to reduce sunburn is to provide water via raised sprinklers when conditions so demand; this reduces the temperature by simulating rainfall (Parchomchuk and Meheriuk, 1996;Dussi et al, 1997). Chemical sun protectants can also be used (Yuri et al, 2000;Schupp et al, 2002). «SunShield», for example, prevents the passage of UV radiation (Curry, 1996), and the use of antioxidants can eliminate the free radicals produced during exposure to intense sunlight (Curry, 1996).…”

The upper region of the Río Negro and Neuquén valley, Argentina (latitude: 38 degrees 55 minutes South) experiences high temperatures and light intensities before the apple harvest. This hinders these fruits turning red and increases the risks of them becoming sunburnt. In the December of two growing seasons (when the fruits were about 43 mm in diameter), still some 80 days before harvest, 15% and 55% density shade nets were placed over "Fuji" apple trees. At harvest time, light distribution was determined at two canopy heights (1 and 3 m) on either side of the trees. Fruiting spurs were examined, and colour, sunburn damage, weight, soluble solid content and flesh firmness of the fruits determined. Specific leaf weight (SLW) was also established. Shade nets notably decreased the amount of photosynthetically active radiation (PAR) available; they also reduced fruit colour (redness), soluble solid content and flesh firmness, and the SLW. The 55% density net decreased fruit sunburn, but no differences were found between the 15% density net and control treatments. Spurs at the bottom of the canopy received less light, and the SLW, as well as the colour and soluble solid content of their fruit, was lower than observed for the higher spurs. The impossibility of exporting fruits damaged by high temperatures and intense solar radiation during ripening requires shade nets be used, their density depending on the conditions experienced.
