  • it relates to a method of controlling gastropods using certain spinosyn derivatives, especially spinetoram.
  • Gastropods such as slugs and snails, are an increasing problem in horticulture and agriculture. They cause severe damage by feeding, and also generate unsightly mucus trails. Gastropods are serious pests, especially of cereals such as wheat, barley, oats and oil seed rape, and also of ornamental and vegetable plants. Gastropods feed both above and below the surface of the ground, on seeds, seedlings and plants, damaging shoots, roots, leaves and flowers, therefore reducing plant stand and crop yield.
