Abstract: A product for killing subsurface and surface soil pathogens including nematodes, wire worms, cut worms, worms, insects, fungi and plant and soil surface pests comprises an extract derived from the plant Tagetes minuta. The extract may be obtained by subjecting whole or parts of the plant Tagetes minuta to steam distillation or the plant or plant parts may be steeped in water for a predetermined period of time to produce a liquid brew. The liquid brew may be solubilized with cellulolytic enzymes or cellulytic organisms. Solvents may also be used to solubilize the extracted brew. The extract may desicated to form a powder and the powder may be compressed to form pellets.
