Abstract: The invention is a composition and a method for agriculture. The composition is a semisynthetic mixture (a) which includes (1) an organic compound which is essentially emitted in the fermentation of vegetable parts of the palm tree or related plant, (2) a vegetable material obtained from the palm tree or related plant and which has been ground, fermented, and stabilized, and (3) an organic compound emitted in minor quantity during the fermentation of the vegetable parts of the palm tree or related plant; and (b) a pheromone which is appropriate to control for the target insect. The method includes the application of the composition to a plantation of palm trees and related plants to be protected.

Abstract: A process for the constant emission of volatile products in the liquid state, which may be either natural or synthetic products or compounds (with or without solutes), uses solid absorbent masses of different materials of a diverse nature and composition. A specifically designed and mutually mechanically linked device forming a homogenous set is used for effectively achieving this process.
