Crops are affected by extreme climatic conditions such as high temperatures and low relative humidity: plants sense that water flow to leaves is excessive and, through hormonal signals guided by abscisic acid, close their stomata. Without water there is no photosynthesis, and with closed stomata there is no CO2 intake for this process either.
Stomatal opening is guided by membrane hyperpolarization through a transporter called ATPase. Haddak Plus helps achieve overexpression of ATPase, causing greater membrane hyperpolarization so stomata remain open longer. With Haddak Plus we're telling the plant: Wait, don't make hasty decisions and don't close your stomata, which prolongs the effective photosynthesis period. With longer photosynthesis periods, there is greater production and accumulation of carbohydrates and osmolytes, which retain water in tissues and prevent dehydration.
Haddak Plus can be applied at all phenological stages, especially during those when an energy imbalance from stress would have negative effects on yield or quality objectives: during flowering, post-harvest recovery, and before critical structural development stages. Trials in Peru in table grapes and blueberries, and in Chile in cherry, hazelnut, and avocado orchards, have measured the extended stomatal opening period with very positive results.
