association de produits phytopharmaceutiques

CONT: Les associations les plus courantes comprennent un ou deux insecticides et un fongicide minéral (cuivre ou soufre) ou organique (manèbe ou zinèbe).
CONT: Lorsque deux ou plusieurs matières actives augmentent l'efficacité d'un composé phytopharmaceutique, on parle d'association [...] de produits.

CONT: ... parathion was formulated with DDT and rosin in an effort to get a longer residual action .... The effectiveness of the combination as a residual ... was found greatly superior to equivalent dosages of DDT or parathion alone.
OBS: The general, ""umbrella"" French concept of ""association"" is best rendered in English by ""combination"": it is, however, common to find more specific references in EN describing the combinations as either containing both insecticide and fungicide, for example, or 2 or more insecticides, or herbicides, etc. Combinations may be sold as such, e.g. AMIZINE (a combination of the herbicides amitrole and simazine), or may be made as tank mixtures just prior to application.
