Saito, Tetsuo published the artcileSystemic inseccticidal properties of certain organic phosphorus compounds to the green peach aphid, Myzus persicae, and the tobacco cutworm, Prodenia litura, Name: Diethyltrichloromethylphosphonate, the publication is Bochu Kagaku (1966), 31(2), 77-81, database is CAplus.
Screening tests of insecticidal activity for ∼50 organophosphorus compounds used the sucking insect, green peach aphid, and the chewing insect, tobacco cutworm. The established systemic insecticides were usually highly toxic to the aphid while being less toxic to the cutworm. One of the thiophosphate esters, ((EtO)2P(S)SCH2CO2(CH2)2Cl) was toxic to the cutworm. Five phosphate esters were toxic to both insects. O,O-Di-Me dichlorohydroxyethanephosphonate and its Ac ester, O,O-di-Me trichlorohydroxyethanephosphonate and its Et Me homolog were more toxic to the cutworm than the aphid. The test plant was cabbage and the test chems. were formulated with Me2CO-C6H6-emulsifier 30:30:30% weight/weight Insecticidal activity was indicated by mortality at concentrations of 1000 ppm. or lower.
Bochu Kagaku published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Name: Diethyltrichloromethylphosphonate.
