SUMMARY Fifteen insecticides were tested in the laboratory against larvae of Mamestra brassicae, a chrysanthemum pest. Seven of these, methomyl, chlorpyrifos, leptophos, iodofenphos, methamidophos, mephosfolan and fenitrothion were significantly more potent than carbaryl, the standard adopted. The performance of the insecticides is discussed in relation to selective action against insects and to mammalian toxicity, to identify those which might be suitable for integrated control or chemical control of noctuid larvae under glass. A technique for monitoring the amount of pesticide deposited on to a target by a Potter Tower sprayer is described.
