Many pesticidal treatments involve the use of pesticides which break down to harmful residues. Withholding periods apply where the level of residue in the relevant plant or animal tissue exceeds maximum residue level allowed for that pesticide by the regulatory bodies. The invention relates to a composition which avoids the imposition of a withholding period while conferring effective relief from infestations of pests, by incorporating 2 or more active pesticidal compounds. Each pesticidally active compound is present in a sufficiently small amount so as not to give exceed the allowable residue level thereby avoiding imposition of a withholding period, whilst the combined effect of the actives is such as to give the required pesticidal kill rate. |
