Determination of mepiquat chloride in cotton crops and soil and its dissipation rates

Ecotoxicology and Environmental Safety, 2012
A simple, accurate and highly sensitive analytical method was developed in this study for determining the residues and dissipation dynamics of mepiquat chloride in soil and cotton crops (including plant and seed). The samples in this method were directly extracted with methanol-ammonium acetate solution and followed by analysis of high performance ...

FT-Raman determination of Mepiquat chloride in agrochemical products

Vibrational Spectroscopy, 2004
Abstract A fast and environmentally friendly procedure has been developed for Fourier transform Raman (FT-Raman) determination of a quaternary ammonium compound, Mepiquat chloride, in pesticide emulsifiable concentrate formulations. The method is based on the measurement of peak area values between 711 and 701 cm −1 corrected using a baseline ...

Second-generation Glyphosate-Resistant Cotton Tolerance to Combinations of Glyphosate with Insecticides and Mepiquat Chloride

Weed Technology, 2008
Field trials were conducted in 2005 and 2006 to evaluate application of glyphosate alone or plus the plant growth regulator mepiquat chloride with 20 different insecticides to second-generation glyphosate-resistant cotton at the pinhead square or first ...

HPLC Determination of Mepiquat Chloride in Commercial Pesticide Formulations

Bulletin of Environmental Contamination and Toxicology, 2009
A simple, fast and precise High Performance Liquid Chromatographic method with diode array detector was developed and single laboratory validated for the determination of mepiquat chloride in soluble concentrate pesticide formulations. From the results obtained, the repeatability of the method expressed as relative standard deviation (%RSD) was found ...

Cotton Response to Planting Date and Mepiquat Chloride

Agronomy Journal, 1988
AbstractFew studies have documented the effect of planting date on cotton (Gossypium hirsutum L.) response to mepiquat chloride (MC) (N,N‐dimethylpiperidinum chloride). Planting dates were mid‐April, early May, and mid‐May during 1982, 1983, and 1984, and consisted of five cultivars representing three general maturity types: early—‘DES 422 ...

Temperature and Mepiquat Chloride Effects on Cotton Canopy Architecture

Agronomy Journal, 1990
AbstractCotton, (Gossypium hirsutum L.) when grown in a fertile, well‐watered, and suitable environment, produces excessive vegetative growth. Such luxuriant growth causes several production problems. A plant growth regulator, mepiquat chloride1 (1,1‐dimethylpiperidinium chloride; BASF Wyandotte Corp., Parsippany, NJ) has been found to reduce ...

Mepiquat Chloride and Irrigation versus Cotton Growth and Development

Agronomy Journal, 1992
AbstractCotton (Gossypium hirsutum L.) produces excessive vegetative growth when grown under optimum water and nutrient conditions. The plant growth regulator Mepiquat Chloride (MC); 1,l‐dimethyl piperidinium chloride reduces vegetative growth and can promote early maturity.

Cotton Response to Mepiquat Chloride¹

Agronomy Journal, 1985
AbstractThe potential for mepiquat chloride (1,1‐dimethylpiperidinium chloride) to control excess vegetative growth and increase yield of cotton (Gossypium hirsutumL.) was evaluated under a wide range of environmental conditions in 35 replicated experiments conducted in the San Joaquin Valley of California from 1979 to 1983.

The effects of gibberellins and mepiquat chloride on nitrogenase activity in Bradyrhizobium japonicum

Acta Physiologiae Plantarum, 2014
Application of plant growth regulators (PGRs) to soybean plants is known to induce changes in nitrogenase activity in root nodules, and this led us to hypothesize that PGRs would affect nitrogenase activity in free-living rhizobia cultures. Little is known about the molecular basis of the effects of PGRs on nitrogenase activity in free-living rhizobia ...
