Abstract

The invention comprises as a new product O,O - dimethyl - O - (b ,b - dichlorovinyl) - phosphate (Cl2C=CH-O-P(O)(OCH3)2). It can be obtained by reacting (b ,b ,b -trichloro-a -hydroxyethyl)-dimethyl phosphonate with an alkaline reacting substance, e.g. an alkali metal hydroxide, alkali metal carbonate, ammonia, or organic amine. The reaction is preferably carried out in water or in a water-soluble low-molecular weight aliphatic alcohol. The reaction temperature can be within the range of 0 DEG to 100 DEG C., temperatures of 20 DEG to 70 DEG C. being preferred. Examples are given in which ammonia, sodium methylate, triethylamine, sodium hydroxide, and sodium carbonate respectively are used as the alkaline reacting substance. The product is stated to have good insecticidal properties and may be used in combination with a liquid or solid inert diluent and with other insecticides or with a fungicide, plant food or fertilizer (see Groups I and VI). Specifications 731,506 and 739,726 are referred to.ALSO:An insecticidal composition comprises O,O-dimethyl-O-(b ,b -dichlorovinyl)-phosphate and a plant food or fertilizer compatible therewith. Specifications 731,506 and 739,726 [both in Group IV(b)] are referred to.ALSO:An insecticidal composition comprises O, O-dimethyl-O-(b , b -dichlorovinyl)-phosphate and a liquid or solid inert diluent, or another insecticide, fungicide, plant food or fertilizer, which is compatible with O, O-dimethyl-O-(b , b -dichlorovinyl)-phosphate. Other insecticides specified are lead arsenate, nicotine, rotenone, pyrethrum, benzene hexachloride, 1, 1, 1-trichloro-2, 2-di(p-chlorophenyl)-ethane, dodecyl thiocyanate, and phenothiazine and specified fungicides are sulphur, copper compounds, and mercury salts. Specifications 731,506 and 739,726 [Group IV(b)] are referred to.
