Abstract
Investigations on effect of method of application and placement of fonofos on its efficacy as a chemical control for wireworms, mainly Limonius californicus (Manner-heim), in Irish potatoes in Idaho were conducted at the Research & Extension Center, Aberdeen, for 3 years. Application methods used were broadcast, band-over, in furrow, and sidedress. Two areas of placement of sidedress treatments also were used: 50 mm to each side of the seed piece and at the same level; and 50 mm to each side and 50 mm above the seed piece. Significant differences in wireworm damage to potatoes due to different methods of application were noted in 2 of the 3 years. Furrow treatments resulted in less wireworm damage to tubers than any other method, with sidedress treatment giving control equal to or better than broadcast. Sidedress level with the seed piece resulted in significantly better results than sidedress 50 mm above in one of the years.
