1. THE CONTROL OF WHEAT BULB FLY IN WINTER WHEAT 1.4. Seed Dressings in Yorkshire.

This article describes seed dressings in Yorkshire. On July 1963, a trial was laid down at High Melton, Yorkshire in England, on medium loam following a bulb crop. Cappelle Desprez wheat was drilled in a randomized block layout. Seed dressings were used at 2 ounce per bushel except for the liquid aldrin which was applied at 3 ounce per bushel of seed. The Bayer 37289 seed dressing was phytotoxic, germination was poor, and there were insufficient plants in April 1963 to obtain an estimate of wheat bulb fly damage. The Bayer 38156 seed dressing was not phytotoxic but gave poor control of wheat bulb fly and a low yield.
