  • Patent number: 5424327
    Abstract: The invention relates to novel combined compositions for combatting plant, animal and sanitarian as well as forestry, horticultural and warehouse pests. These compositions contain a pyrethroid-type insecticide as an insecticidally active ingredient and at least one fungicide inhibiting the ergosterol biosynthesis as activity-strengthening agent as well as optionally piperonylbutoxide and other additives.The advantages of the compositions according to the invention consist therein that the activity-strengthening substances used are fungicidal agents widely used and have an advantageous toxicology. The activity-strengthening agent exerts a synergistic effect together with the pyrethroid-type insecticide.The combinations according to the invention bear an outstanding importance in the protection of stored crops.

  • Patent number: 4243660
    Abstract: The invention relates to a composite insect attractant for male cabbage moths (Mamestra brassicae) containing (Z)-11-hexadecenyl acetate and (Z)-11-heptadecenyl acetate as active agents in a weight ratio of 70 to 90:80 to 1, optionally along with a liquid or solid adjuvant. An insect trap can contain the composition which is used for attracting and trapping cabbage moth. Their mating is disrupted by air permeation techniques. (Z)-11-heptadecenyl acetate is a synergistically active new compound. The composition according to the invention produces a significantly stronger stimulating reaction on male cabbage moths than the known sex lure compositions.
