- ... BACKGROUND AND AIM: Entomopathogenic nematodes (EPN) use odor cues to locate and infect their insect hosts in the soil, making them an important tool in sustainable management of agricultural insect pests. However, very little information is available on the role of soil bacteria in mediating belowground interactions between plants, herbivores and the EPN. In this study, a maize-herbivore-entomopa ...

- ... AIMS: Rhizodeposits collected from hydroponic solutions with roots of maize and barley, and seed mucilage washed from chia, were added to soil to measure their impact on water retention and hysteresis in a sandy loam soil at a range of concentrations. We test the hypothesis that the effect of plant exudates and mucilages on hydraulic properties of soils depends on their physicochemical characteris ...
