Disclosed herein are flowable pesticide formulations comprising; 40-60% by weight of the total formulation of a liquid water-insoluble toxicant or mixture of toxicants, 1-25% weight of the total formulation of a hydrocarbon oil from the group consisting essentially of benzene, chlorobenzene and straight chain petroleum aliphatic solvents, 1-10% by weight of the total formulation of an alkali lignin suspending agent, and the remainder being water. When subjected to a higher shear, the lignin suspending agent along with the hydrocarbon oil, liquid toxicant, and water produces a thixotropic formulation with such rheological properties as to prevent or drastically reduce sedimentation and liquid phase separation. |
