Effect of cotton seed size and seeding density on cotton growth, development, and yield

Agronomy Journal, Volume 116, Issue 6, Page 2967-2975, November/December 2024.
Abstract Interest in cotton seed size and seeding density exists due to increased seeding cost and overall decreased seed size of cotton varieties. An experiment was conducted in 2019 and 2020 in Jackson, TN, Starkville, MS, and Brooksville, MS, to determine the impact of seed size, seeding density, and variety on cotton plant development and yield ...

Mepiquat chloride and paclobutrazol in size reduction of Arundina graminifolia

Agronomy Science and Biotechnology, 2017
The objective of this study was to evaluate the effect of mepiquat chloride and paclobutrazol on reducing the size of Arundina graminifolia for commercialization as a flower vase. The experiment was conducted in a greenhouse with 50% of shading. Plants were grown in one-liter black polypropylene vase filled with commercial substrate Plantmax ® and sand

Review of the existing maximum residue levels for difenoconazole according to Article 12 of Regulation (EC) No 396/2005

EFSA Journal, Volume 22, Issue 8, August 2024.
Abstract According to Article 12 of Regulation (EC) No 396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance difenoconazole. To assess the occurrence of difenoconazole residues in plants, processed commodities, rotational crops and livestock, EFSA considered the ...

Mepiquat Chloride Effects on Castor Growth and Yield: Spraying Time, Rate, and Management

Crop Science, 2018
The use of plant growth regulators on castor (Ricinus communis L.) plants may be an alternative to reduce excessive vegetative growth, which would ease harvest and even increase seed and oil yield. This study aimed to evaluate the effects of both spraying time and rate of the plant growth regulator mepiquat chloride (MC) on growth parameters, yield ...

The 2022 European Union report on pesticide residues in food

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Under European Union legislation (Article 32, Regulation (EC) No 396/2005), the European Food Safety Authority provides an annual report assessing the pesticide residue levels in foods on the European market. In 2022, 96.3% of the overall 110,829 samples analysed fell below the maximum residue level (MRL), 3.7% exceeded this level, of which 2 ...

Growth regulator losses from cotton plants due to rainfall Perdas de reguladores de crescimento no algodoeiro devido à chuva

Scientia Agricola, 2010
Plant growth regulators (PGRs) applied to cotton plants (Gossypium hirsutum L.) can be washed off by rainfall. It is expected that the closer the rainfall to spraying time, the higher the product loss and the higher the amount of product to be reapplied ...
