Abstract/Contents:"Activity of nine fungicides against mycelial growth of Rhizoctonia solani in potato dextrose broth and in pot tests as seed treatment against cowpea seedling rot in infested soil was differentially influenced by clay minerals, humic acid and micronutrients. Humic acid, extracted from farmyard manure, considerably lowered the activity, both in vitro and in vivo, of all fungicides except chloroneb. Montmorillonite caused substantial decrease in disease control by fungicides but enhanced the toxicity of 2-methoxyethyl mercury chloride (MEMC), and quintozene in culture. Kaolinite inactivated carbendazim, benomyl and thiophanate-methyl in nutrient broth but had little effect on disease control by these fungicides. The six micronutrients altered the activity of fungicides to varying levels often without definite correlation between in vitro and in vivo results. The results of in vitro growth inhibition tests are largely inapplicable to disease control tests in infested soil mainly due to the differences in the ambient conditions of the two systems."
