Water absorbent polymer AIDS in the infestation of field sites with meloidogyne eggs.
The root-knot nematode (Meloidogyne spp.) is one of the principal nematode pests of field and vegetable crops in the southern United States (6). Meloidogyne spp. are generally not uniformly distributed in naturally infested field sites, and sites frequently contain more than one species, thus complicating the evaluation of breeding lines for nematode resistance. To facilitate evaluation of nema...
متن کاملMultiresidue analysis of pesticides in vegetables and fruits using a high capacity absorbent polymer for water.
A single extraction and a single clean-up procedure was developed for multi-residue analysis of pesticides in non-fatty vegetables and fruits. The method involves the use of a high capacity absorbent polymer for water as a drying agent in extraction from wet food samples and of a graphitized carbon column for clean-up. A homogeneously chopped food sample (20 g) and polymer (3 g) were mixed to a...
متن کامل"Nanofiltration" Enabled by Super-Absorbent Polymer Beads for Concentrating Microorganisms in Water Samples.
Detection and quantification of pathogens in water is critical for the protection of human health and for drinking water safety and security. When the pathogen concentrations are low, large sample volumes (several liters) are needed to achieve reliable quantitative results. However, most microbial identification methods utilize relatively small sample volumes. As a consequence, a concentration ...
متن کاملSugarcane for water-limited environments. Variation in stomatal conductance and its genetic correlation with crop productivity.
Stomatal conductance (g(s)) and canopy temperature have been used to estimate plant water status in many crops. The behaviour of g(s) in sugarcane indicates that the internal leaf water status is controlled by regular opening and closing of stomata. A large number of g(s) measurements obtained across varying moisture regimes, locations, and crop cycles with a diverse sugarcane germplasm compose...
متن کاملWater balance of a sugarcane crop: Quantitative and qualitative aspects of its measurement
The quantification of soil water balance components was conducted in a sugarcane (Saccharum officinarum L.) field differently managed, as well as a qualitative analysis of the methodologies used for their estimation. The study was conducted in randomized block experiment with four replicates and three treatments: bare soil, mulched soil using trash left on the soil surface after harvest, and so...
