The effectiveness of insecticidal seed dressings against soldier fly larvae

Reduction of soldier fly damage to ryegrass seedlings by insecticidal seed treatments

“…Carbofuran has been shown to be effective against soldier fly larvae in pot and field trials (Dixon & Parr 1975;Mackay et ale 1974), and this trial confirms this compound's efficacy. The wet conditions may have contributed to the somewhat shorter soil life than has been observed elsewhere (Abdellatif et ale 1967;Harris 1969).…”

“…Trichlorphon gave good control of soldier fly larvae in pots (Dixon & Parr 1975), but this trial shows it to be ineffective in the field. This could be associated with the longer time taken for larvae to reach seedlings in the field.…”

“…A number of insecticides have been shown to be active against soldier fly (Inopus rubriceps) larvae (Mackay et ale 1974;Saunders 1975;Dixon & Parr 1975). Accurate placement of the insecticide with the seed is highly desirable in order that seedling roots have immediate access to the material.…”

Use of insecticides during autumn to control soldier fly larvae and increase pasture production

“…There was no overall difference between the effectiveness of seed treatment and granular formulations. The less toxic materials, methomyl and omethoate, were less effective, even though pot trials (Dixon & Parr 1975) had shown them to be promising. Aldicarb and oxamyl were less effective than isophenphos and carbofuran at similar rates.…”
