Strawberry yield response to fertilizer, paclobutrazol and chlormequat

Scientia Horticulturae, 1988
Abstract Unadjusted vegetative and reproductive variates of strawberry ( Fragaria × ananassa Duch.) grown in a glasshouse were studied using analysis of variance. Two-dimensional partitioning was used to account for yield variation due to successive orthogonal variates, 20 N-8.7 P-16.6 K fertilizer at 45 or 180 mg/pot, paclobutrazol (PP333) at 0 ...

Influence of Chlormequat Chloride and Maleic Hydrazide on Yield and Yield Components of Rice (Oryza sativa L.)

International Journal of Plant & Soil Science
Rice productivity is often affected by climate variability and lodging, especially in coastal regions, leading to yield losses and poor grain quality.

Factors affecting the uptake of chlormequat into cereal leaves

Annals of Applied Biology, 1985
SUMMARYThe effects of site of application, growth environment, droplet size, and formulation adjuvants on the retention and uptake of 14C‐chlormequat by wheat cv. Avalon and barley cv. Sonja have been examined using solutions applied by a micro‐sprayer.

Simultaneous determination of the quaternary ammonium pesticides paraquat, diquat, chlormequat, and mepiquat in barley and wheat using a modified quick polar pesticides method, diluted standard addition calibration and hydrophilic interaction liquid chromatography coupled to tandem mass spectrometry

Journal of Chromatography A, 2019
In this study, a modified Quick Polar Pesticides (QuPPe) method, optimized by a central composite design, was developed to determine quaternary ammonium pesticides (QUATs) residues in barley and wheat by ultra-high-performance liquid chromatographic ...

Improved sensitivity in detection of chlormequat by liquid chromatography–mass spectrometry

Journal of Chromatography A, 2000
Two published separations, using electrospray mass spectrometry (ES-MS), exhibit significant differences in limits of detection (LODs) for chlormequat cation in pear. Separation on ODS1, confirmed to result from ion-exchange, gives shorter analysis times and calibration over a wider concentration range than on an SCX cation-exchange column.

Bioaccumulation of deltamethrin, tebuconazole and chlormequat chloride in T. molitor larvae and risks associated with their human consumption

, 2020
Edible insects are generally reared on agricultural product-based diets. These feeding substrates may contain pesticides or toxins that are derived from field practices for plant growth and defence...

Bestimmung von Chlormequat‐(Chlorcholinchlorid)‐Rückständen in Milch

Food / Nahrung, 1974
AbstractEs wird ein Verfahren zur Bestimmung von Chlormequat beschrieben, das es ermöglicht, Chlormequat‐Rückstände in Milch im Bereich der Toleranz von 0,05 ppm noch zu erfassen. Wegen des hohen Überschusses an Calciumionen ist die für pflanzliche Produkte gut geeignete Kationenaustauscher‐Chromatographie als intensiver Reinigungsschritt für Milch ...

Occurrence and risks associated with chlormequat residues in a range of foodstuffs in the UK

Food Additives and Contaminants, 2004
Trends in the usage pattern of chlormequat (a plant growth regulator) on cereal crops in the UK over the past 6 years are presented. The figures have been supplemented by monitoring of chlormequat residues in food commodities through the UK surveillance programme, and for cereals, the carry-through into a number of processed cereal-based foods has been

The skeletal developmental toxicity of chlormequat chloride and its underlying mechanisms

Toxicology, 2017
Chlormequat Chloride (CCC), a widely used plant growth regulator, could decrease body weight in animals; however, the mechanism has not been well studied. This study was designed to evaluate the skeletal development toxicity of CCC on pubertal male Sprague-Dawley (SD) rats and to investigate whether CCC impacts the development of chondrocyte ...

Simple ion chromatographic method for the determination of chlormequat residues in pears

Journal of Chromatography A, 2001
Current methods for quantitative determination of chlormequat residues in food crops are characterized by rather low recoveries and the need for derivatization (in case of gas chromatography, GC), or by high capital investment (in case of liquid chromatography-mass spectrometry, LC-MS).
