Notes:
Between 1967 and 1970, 19 insecticides in nine trials in southern and eastern England were evaluated for the control of pre-blossom pests on apple. Where sprays were applied at the green-cluster stage, azinphos- methyl, dichlorvos, ‘Dursban’, fenitrothion, methidathion and phos- alone gave an equivalent or better control than DDT of winter moth larvae, tortricid larvae and apple capsid. Iodofenphos, phosmet and trichlorphon were also as effective as DDT against tortricid larvae and apple capsid but gave more variable control of winter moth larvae. Carbaryl, Ciba C11042, cyanophos, monocrotophos and pirimiphos-methyl in single trials and Du Pont 1642 and ‘Torak’ also gave effective control of winter moth and tortricid larvae; no data were available on their effect on apple capsid.Dichlorvos, ‘Dursban’. fenitrothion, methidathion and phosmet were particularly effective against apple sucker. Cyanophos, Du Pont 1642, iodofenphos, monocrotophos and ‘Torak’ were also effective in single trials, but azinphos-methyl, phosalone and trichlorphon gave less effective control of apple sucker when infestations were heavy.In one trial, azinphos-methyl, dimethoate and fenitrothion effectively controlled apple-grass aphid. Where a bud-burst spray was applied, azinphos-methyl, DDT, Du Pont 1642,‘Dursban’ and iodofenphos in a single trial all gave some control of apple blossom weevil. Although green-cluster sprays are generally too late to prevent some damage by apple blossom weevil, some degree of control of larvae was achieved at that stage by azinphos-methyl, Ciba C11042, Du Pont 1642, pirimiphos-methyl and ‘Torak’.In a single trial on pear, azinphos-methyl or phosalone applied at green cluster or white bud, or methidathion at green cluster, gave a control of winter moth larvae equivalent to DDT.
