Full definitions are given in the DEFINITIONS (Full Definitions) Field. An independent claim is also included for use of (I) in spray application on plants and plant parts in combination with an active substance comprising insecticides, pheromones, acaricides, fungicides, nematicides, herbicides, growth-regulating substances, safeners, substances influencing plant maturity, bactericides or fertilizers, and for application on genetically modified varieties, their seeds, or on acreage on which these varieties grow. [Image] ACTIVITY : Plant protectant. The ability of (I) to protect plant against stress e.g. cold or drought stress was tested in Zea mays. The results showed that (Ia) exhibited a effective degree of greater than 5%, which was calculated by the formula effective degree is equal to (damaged value of untreated and stressed controls minus value of damaged plants treated with test compound) x 100/damaged value of untreated and stressed controls. MECHANISM OF ACTION : None given.
