The invention relates to the technical field of pesticides, and discloses an insecticidal composition containing
dinotefuran. The insecticidal composition contains 9-51% of effective
active components, 1.5-15% of a synergist, 5-40% of an auxiliary agent and the balance of water, the effective
active components are
dinotefuran and
fenobucarb, and the weight ratio of
dinotefuran to
fenobucarb is 1: 2. The synergist is a mixture of a biological
enzyme and a
polymer emulsifier, wherein the weight ratio of the biological
enzyme to the
polymer emulsifier is 7: 1-1: 1. The insecticidal composition disclosed by the invention is used for preventing and treating rice planthoppers, can obviously improve the permeability and wettability of a medicament, can act on pests from multiple aspects, achieves the purpose of effectively preventing and treating the pests, reduces the dosage of the medicament in the field, saves the economic cost, reduces the
pollution of the medicament to the environment, and has good
economic benefits and
economic benefits. And the risk that pests generate resistance to the
pesticide is also reduced.
