Claim Text:
1. A method for protecting a plant with a macrolide lactone comprising applying to the plant a controlled-release microcapsule, each microcapsule enclosing at least one macrolide lactone(s), wherein the microcapsules have an average particle size of 0.5-2 μm with 90% of the particle sizes are below 15 μm, whereby, simultaneously: (a) dermal and acute toxicity of the controlled-release microcapsule is less than that of an emulsion of the same macrolide lactone(s) having the same concentration of the macrolide lactone(s) as the controlled-release microcapsule; (b) UV and visible degradation of the macrolide lactone in the controlled-release microcapsule is less than that of an emulsion of the same macrolide lactone(s) having the same concentration of the macrolide lactone(s) as the controlled-release microcapsule; (c) the controlled-release microcapsules have an increased biological effect than that of an emulsion of the same macrolide lactone(s) having the same concentration of the macrolide lactone(s) as the controlled-release microcapsule; and (d) the corresponding macrolide lactone(s) are microencapsulated with an efficiency of 90% or more.
