Fertilizer/pesticide compositions are disclosed which include a fertilizer component and an active component. The fertilizer component includes plant nutrients, and the active component includes an active material, such as a pesticide, which has a desired effect on plant growth or health when released to the plant over an extended period of time. In a preferred form, the fertilizer component is admixed with the active component and a binder and compressed to form a briquette in which the fertilizer component occludes the active component. The briquette is essentially free of significant quantities of materials which have a high solubility in water. Thus, when a briquette is placed in the soil, it releases nutrients and the active material into the soil over an extended period of time for delivery to the plant. A method of treating plants with such fertilizer/pesticide compositions is also disclosed.
