An absorbent composition of matter acts as a carrier for an active ingredient. The active ingredient is gradually released by the carrier in a controlled manner, which is compatible with the environment and current tendencies towards the use of organic and biodegradable products. The carrier is characterized as being particles obtained from the milling, separation, air wash and classification of the different fractions obtained from corncobs. The active ingredient is, for example, an essential oil, such as garlic oil or extract that may be combined with other essential oils for a synergistic effect that results in an improved insecticide/fungicide that is natural and contains no chemical additives. Alternatively, an artificially obtained substitute, for example, allyl isothiocyanate (AITC), can be used as a substitute for mustard seed oil.
