“…Epicuticular waxes are a barrier to the retention and penetration of foliar fertilisers into plant organs (Jenks and Ashworth 1999). Almost all plant surface waxes are hydrophobic and repel waterbased sprays.…”

“…The thinnest areas of the waxy layer are covering the stomatal pore (Currier and Dybing 1959). This is one reason why the timing of foliar sprays is often targeted to stomatal opening (Jenks and Ashworth 1999). Several studies (Jenks and Ashworth 1999;Kirkwood 1999;Eichert and Burkhardt 2001) the chemical or physical removal of cuticular waxes increased the penetration of foliar-applied nutrients.…”

Potential for foliar phosphorus fertilisation of dryland cereal crops: a review

2010

View full text Add to dashboard Cite

Although not commonly used in dryland cropping systems to date, foliar phosphorus (P) fertilisation may allow a tactical response to prevailing seasonal climatic conditions, with the added benefit of reduced input costs at sowing. However, variable outcomes have been reported from field trials predominantly conducted in the USA, and to a lesser degree in Australia. The effectiveness of foliar P is dependent on soil P status, soil water status, crop type, fertiliser formulation and prevailing climatic conditions. This review argues that the potential of foliar P fertilisation in Australian dryland cereal cropping could be enhanced by altering formulations for enhanced leaf penetration using adjuvants, and by accurately assessing the responsiveness of sites before application. This review demonstrates that it is important to use appropriate techniques such as isotopic labelling, to measure the efficacy and mode of action of foliar formulations.

“…Wax composition can vary substantially with species, ontogeny, and environmental growth conditions (Jenks and Ashworth, 1999). In most cases, the majority of compounds comprising the cuticular wax are derived from very-long-chain fatty acids (VLCFAs; C20-C34), including alkanes, aldehydes, primary and secondary alcohols, ketones, and esters (Table I).…”

The Formation and Function of Plant Cuticles

2013

The plant cuticle is an extracellular hydrophobic layer that covers the aerial epidermis of all land plants, providing protection against desiccation and external environmental stresses. The past decade has seen considerable progress in assembling models for the biosynthesis of its two major components, the polymer cutin and cuticular waxes. Most recently, two breakthroughs in the long-sought molecular bases of alkane formation and polyester synthesis have allowed construction of nearly complete biosynthetic pathways for both waxes and cutin. Concurrently, a complex regulatory network controlling the synthesis of the cuticle is emerging. It has also become clear that the physiological role of the cuticle extends well beyond its primary function as a transpiration barrier, playing important roles in processes ranging from development to interaction with microbes. Here, we review recent progress in the biochemistry and molecular biology of cuticle synthesis and function and highlight some of the major questions that will drive future research in this field.

How effective are common household preparations on removing pesticide residues from fruit and vegetables? A review

Nowadays, the use of pesticides is inevitable for pest control in crops, especially for fruit and vegetables. After the harvest from raw agricultural commodities, the amount of pesticide residues in food is mainly influenced by the storage, handling and processing that follow. If good agricultural and good manufacturing practices are enforced effectively, the amount of pesticide residues would be brought below the corresponding maximum residue level. Thus, the consumption of raw and/or prepared fruit and vegetables would be safe. Nonetheless, reports regarding pesticide residues in fruit or vegetables on mass media have been worrying consumers, who are concerned about the adverse effects of pesticide residues. As a result, consumers perform household processing before consumption to reduce any related risks. However, can these preparations effectively remove pesticide residues? Reviewing the extensive literature, it showed that, in most cases, washing and soaking can only lead to a certain degree of reduction in residue level, while other processing such as peeling, soaking in chemical baths and blanching can reduce pesticide residues more effectively. In general, the behaviour of residues during processing can be rationalised in terms of the physico-chemical properties of the pesticide and the nature of the process. In contrast, the reported studies are diversified and some areas still lack sufficient studies to draw any remarks. Recommendations are provided with respect to the available information that aims to formulate an environmental friendly, cost-effective and efficient household processing of fruit and vegetables to reduce pesticide residues. © 2017 Society of Chemical Industry.
