Soil texture, infective juvenile concentration, and soil organic matter influence the efficacy of Steinernema feltiae isolate Lican Ray

, and loam soil at 40 (35–75%). The lowest larval mortality occurred in clay and sandy soil at 40 cm (Fig. 3). Vertical movement At three DAI (F (4, 36) = 4.31; p = 0.006), highest mortality was recorded in loam soil at 30 cm (100%) and 50 cm (60%), and in sandy loam soil at 30 cm (64%). The lowest mortality level was observed at 50 and 70 cm in most soils (approximately 0–12%) (Fig. 4). At six DAI (F (4, 36) = 5.54; p = 0.001) and nine DAI (F (4, 36) = 7.78; p < 0.001), significantly highest

Movement of seed- and soil-applied fluopyram in soil columns

nematodes were recorded. Treatments were arranged in a completely randomized design (CRD) with three replications and the experiment was conducted three times. To evaluate the effect of soil texture on fluopyram movement, plastic tubes (6-mm-diam.×160-mm-long) filled with <2.0-mm-diam. sterilized sandy loam soil (62% sand, 30% silt, and 7% clay; <1% organic matter; pH 6.0; CEC 11.3 cmol+/kg) were used in the second experiment. Methods used were the same as described in the first experiment with the

Influence of Root Exudates and Soil on Attachment of Pasteuria penetrans to Meloidogyne arenaria

to influence the lipophilicity of the nematode surface coat, auxins and kinetins did not affect spore attachment compared with PBS. Root exudates reduced spore attachment more in sterilized soil than in natural soil. Sterilization may have eliminated microbes that consume root exudates, or altered the chemical components of the soil solution or root exudates. Root exudates caused a greater decrease in spore attachment in loamy sand than in a sandy loam soil. The sandy loam had higher clay content
