Composition containing diallyl (poly)sulfides, preferably extracted from garlic, useful as biopesticide, e.g. for controlling pests damaging agricultural or food products, wood or textiles
A new composition (I) contains diallyl sulfide (DAS), diallyl disulfide (DAS2), diallyl trisulfide (DAS3) and diallyl tetrasulfide (DAS) in a combined amount of at least 1 mg/g. An independent claim is included for the preparation of (I). ACTIVITY : Insecticide; Acaricide; Pesticide; Antiparasitic. A garlic extract comprising 0.741 mg/g DAS, 1.898 mg/g DAS2, 6.033 mg/g DAS3 and 1.347 mg/g DAS, together with 6,854 mg/g gamma -glutamyl-S-allyl-cysteine (Gluacs), had LC 50values of 1.62 mg/l against Tineola bisselliella, 1.3 mg/l against Reticulotermes santonensisand 24.96 mg/l against Callosobruchus maculatus. For comparison, the commercially available garlic extract Garlic Barrier(RTM), containing 0.003 mg/g DAS, 0.007 mg/g DAS2, 0.010 mg/g DAS3 and 0.002 mg/g DAS4, had LC 5067.4 mg/l against Tineola bisselliella, 370.12 mg/l against Reticulotermes santonensisand 242.82 mg/l against Callosobruchus maculatus. MECHANISM OF ACTION : None given in the source material.
