Technical Field

The invention belongs to the technical field of pesticides, and relates to an insecticidal composition containing d-limonene.

Background

D-limonene (D-limonene), molecular formula: c₁₀H₁₆D-limonene is orange oil extracted from orange peels by a professional cold pressing technology, belongs to a natural plant source pesticide, has a unique physical contact killing effect on pests, has no cross resistance with a common chemical pesticide, and has an insecticidal mechanism that a wax layer on the body surfaces of the pests is dissolved, so that the pests are quickly knocked down and die in an obvious water loss state.

Cnidium lactone, celastrus angulatus, oxymatrine, chamaejasmine, tea saponin and stemonine are botanical insecticides, and the most easily generated problem for preventing and controlling pests is the generation of drug resistance in the actual process of agricultural production. The compounding of different kinds of components is a common method for preventing and controlling resistant pests. Different components are compounded, and whether a certain compound has synergism, addition or antagonism is judged according to the actual application effect. In most cases, the compounding effect of the pesticide is additive effect, the compounding with real synergistic effect is less, and especially the compounding with very obvious synergistic effect and very high co-toxicity coefficient is less. A large number of experiments of the inventor show that after d-limonene is compounded with celastrus angulatus, cnidium lactone, oxymatrine, chamaejasmine, tea saponin and stemonine, the synergistic effect is obvious, the environmental compatibility is excellent, the pesticide dosage is greatly reduced, and when the d-limonene is compounded with the celastrus angulatus, the cnidium lactone, oxymatrine, chamaejasmine, tea saponin and stemonine, no relevant report is found at home and abroad.
