    Rapid Determination of Pesticides in Spinach

    Highly pigmented foods, such as spinach, require cleanup prior to analysis for pesticide residues. A dual-layer SPE tube containing graphitized carbon and aminopropyl on silica (NH2) is often used because; Carbon removes pigments and sterols and NH2 removes fatty acids, polar pigments, organic acids, and sugars. Removing these matrix materials reduces interferences that can lead to ion suppression in LC-MS, inlet contamination in GC-MS, and column contamination for both techniques. Our Supel Sphere Carbon/NH2...

    Improved Recovery of the Fungicide Carbendazim

    Fungicide carbendazim can some times be used to combat mold on citrus fruits including oranges. Recently, low residue levels of the fungicide were reported to be present in the bulk orange juice import shipments to the USA. Because this compound can persist through processing steps and may be found in the final consumer product, many government agencies have established maximum residue limits (MRLs) to ensure the safety of their population. Presented here is a single method, involving fast and effective QuEChERS...

    Hydroponics

    `A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks...

    Determination of the carbendazim content in orange and other citrus juice produce

    Introduction

    Fungicide Carbendazim (Mercazole, Carbendazole) is widely used in agriculture to exterminate black mold (spot) on orange trees and treat fungus diseases of other fruit-bearing plants. According to the data of the World Health Organization, Carbendazim is toxic for liver, impacts reproductive system, and is considered to be a potentially cancerogenic compound. In most of the developed countries, the residual content of this fungicide is subject to national and international...

    Frost Protection for the Horticulture Industry

    The main benefits of the Toptex winter protection fabric can therefore be listed as creating barrier against wind chill and UV radiation, thereby nullifying temperature extremes, allowing the exchange of gases, which leaves the plants to breath and thereby avoids plant disorder. Furthermore, the Toptex winter protection fabric provides necessary light absorption while also allowing water absorption: whether laid on the ground or in the tunnel method, precipitation is carried within the fabric.
