Evaluation of seed-treatment chemicals on sugarbeets, grain sorghum, and peanuts

In field and pot trials in 1967-9, stands of sugar beet, sorghum and groundnuts grown in soil infested with Rhizoctonia solani and Fusarium spp. were increased by fungicidal seed treatments. The applied fungicides were still effective after the treated seed had been stored for 1 year. Although in 1967 and 1968 some groundnut yields from treated seed tended to be higher than from untreated seed, no significant yield effects were observed. Seed treatments improved the germination of sugar beet and sorghum. The most effective treatment for sugar beet was 3 oz Captan 75 W/cwt seed and for sorghum was Captan 75 + dieldrin 1.5 at 3 oz/cwt seed. Effective treatments for groundnuts included 3 oz Botran 75 W [dicloran] + 3 oz Difolatan 8OW [Captafol], 3 oz Botran + 3 oz Captan, 6 oz Vitavax 75 W [carboxin], 4 oz Difolatan 80W or 6 oz Terracoat/cwt seed
