Sun and heat are necessary for the growing process but too much of a good thing can be a problem.
Excess light energy can overwhelm the light absorption capacity of a plant, exceeding its photosynthesis ability. When combined with high temperatures, this is where sunburn occurs.
Strengthening the fruit cuticle provides the extra protection needed to help apples stay cool throughout the growing season.
Parka is an excellent plant health solution proven to fortify the fruit cuticle, which helps to minimize sunburn incidence by 44%.
It increases stress tolerance in apples by enhancing antioxidant capacity as well as the amount of chlorophyll and pheophytin, both essential tools needed to manage light energy during photosynthesis.
This allows the fruit to focus excess light energy on growth when conditions arise that typically result in sunburn damage. Supplementing the cuticle with Parka gives you increased fruit quality and marketable yields.
