Effect of Soil pH on Nematicide Efficacy on Soybean

  • D. P. Schmitt

Abstract

To determine the efficacy of selected nematicides under different soil pH regimes in a sandy soil, soil pH ranges were achieved by adding lime or sulfur. Nematicides increased soybean yields, and their efficacy was generally not influenced by soil pH. Belonolaimus longicaudatus was negatively correlated (r = -0.58, P = 0.01) with yield in 1977. Key words: Belonolaimus longicaudatus, chemical control, Criconemella ornata, DBCP, ethoprop, fenamiphos, fensulfothion, Glycine max, Heterodera glycines, ring nematode, soybean, soybean cyst nematode, sting nematode.
