ΚΠ

1961 A. Calderbank et al. in Chem. & Industry 13 May 630/1 A new class of heterocyclic thiophosphate ester has been prepared which combines outstanding aphicidal properties with low toxicity to other insect species and to mammals... One of the most active members is S-(4, 6-diamino-1, 3, 5-triazin-2-ylmethyl)O, O-dimethyl phosphorothiolothionate.., which has been given the common name ‘menazon’.

1964 Which? Apr. 114/1 The organophosphorus compounds, such as dimethoate, malathion, menazon, are mainly poisonous to sucking insects, such as greenfly.

1972 Bull. Entomol. Res. 62 177 In order to ensure protection from secondary spread of rosette virus on the sprayed plots, menazon was applied five times at weekly intervals.

1981 S. Buczacki & K. Harris Pests, Dis. & Disorders Garden Plants 164 Systemic insecticides, such as dimethoate, formothion and menazon, give best control of aphids feeding in protected situations.
