Description
Technical field
The invention belongs to the agricultural insecticide field, particularly relate to a kind of Pesticidal combination that contains Avermectin or Affirm (Merck Co.).
Background technology
Lepidoptera pest is the primary pest (such as snout moth's larva, bright and beautiful earworm, diamond-back moth, beet armyworm, prodenia litura etc.) of agricultural production, the agricultural production of serious harm China.And in the agricultural production real process, pest resistance to insecticide is to affect the important problem of control of insect.It is composite that the effective ways of control resistant insect are that the different cultivars composition carries out, and simultaneously, the composite of agricultural chemicals also is expanding prevention spectrum and the effective measures that improve preventive effect.
ZJ3757 belongs to the O-formammidotiazol-benzamide insecticide, has following chemical structural formula (I):
