Stressoil reduces leaf fall when applications of mineral oils are carried out during high temperature periods.
Stressoil helps ensure that the plant metabolic activity does not decrease at key times that determine the final quality of the fruit and production.
It is recommended to stop treatments with mineral oils when temperatures are high – above 30 °C –; however, this condition is difficult to achieve at times of application in summer months. Mineral oils create a fatty film on the surface of the plant, thus preventing it from transpiring. This action, in combination with high temperatures, leads to an increase in vapour pressure, which originates the production of highly reactive free radicals, causing irreversible damage at cell level (ostioles of the stomata) and thus resulting in burns, desiccation, defoliation, etc.
