SUMMARY During 14 trials on dry harvesting peas two sprays of fenthion, “Supracide”, and in one trial Bayer 37344, reduced the pod infestation by pea moth by over 90 per cent which was significantly better than DDT. Fenitrothion, dimethoate, azinphos‐methyl, TDE, R.D.18040 and carbaryl usually gave similar results to DDT. Bacillus thuringiensis used in one trial only gave no control. Single sprays of DDT, fenthion, azinphos‐methyl or parathion gave a poor control. Low volume sprays of 30 g.p.a. at three sites and applications at 50–60 g.p.a. gave similar results to high volume sprays with the spraying equipment used.
