The study found that CCC (300 mg/L) resulted in a large rise in the biomass of lily leaves and stems, a significant drop in the gibberellic acid (GA) content in lily bulbs, and an increase in indole-3-acetic acid (IAA) content in leaves.

Absorption, Distribution and Excretion
Chlormequat was determined in four /sow/ milk samples in the range of 0.4 ng/g to 1.2 ng/g...
The distribution of Chlorocholine chloride (CCC) in the eggs of laying hens was studied using 15N-CCC. Twelve layers (37 weeks old) were divided into four groups and used in this study consisting of three feeding phases. In phase one (7 days), all the hens received a CCC-free diet [165 g CP/kg dry matter (DM); 11.58 MJ ME/kg DM]. In phase two (11 days), four levels of 15N-CCC: 0, 5, 50 and 250 ppm were added to the respective diets, while in phase three (7 days), CCC-free feed was again offered. Egg samples were taken and the 15N content of egg yolk and albumin were determined. At the end of phase two, there was a significant (p < 0.05) increase in 15N content in egg yolk from hens fed the 50 and 250 ppm CCC diets and in albumin from hens fed the 250 ppm CCC diet. The estimated 15N-CCC residue was 1.71, 6.64, 28.80 ppm in egg yolk and 1.58, 1.08 and 4.50 ppm in albumin from hens fed 5, 50 and 250 ppm CCC, respectively. The CCC residue, from quantitative analysis ranged from 0.21 to 0.93 and 0.93 to 2.43 ppm in yolk of hens fed 50 and 250 ppm CCC, respectively, whereas a range of 0.40-1.46 ppm, was found in the albumin of hens fed 250 ppm. The difference in measured CCC in yolk and albumin and that estimated from 15N-CCC could have been due to breakdown products of 15N-CCC. Seven days after withdrawal of 15N-CCC, the estimated 15N-CCC residue in egg yolk decreased to 0.43, 2.45 and 15.59 ppm, on 5, 50 and 250 ppm CCC dietary treatments, respectively, and to 2.46 ppm in albumin from hens fed 250 ppm CCC. The higher increase in 15N content could have been due to a higher incorporation of 15N-CCC into yolk than albumin during the process of rapid yolk deposition. This experiment showed that consumed CCC is distributed both into yolk and albumin in a dose dependent manner and that CCC is metabolized in laying hens. However, the level of CCC in the diet which could lead to accumulation of detectable CCC levels in eggs as observed in this study, is much higher than the established maximum residual limits in grains.
In mammals, following oral administration, 97% is eliminated within 24 hr, principally as the unchanged substance.

Metabolism / Metabolites
An experiment was conducted to evaluate the metabolic products of chlorocholine chloride (CCC) in eggs and meat of laying hens fed a diet containing (15)N-CCC. Ten brown laying hens were randomly divided into two groups of five each. One group was offered (15)N-CCC free diet while the other group received a diet with 100 ppm (15)N-CCC for 11 days. Samples of eggs and meat from the laying hens were collected. Egg yolks and albumen were separated. Meat was collected from the breast and femur. The metabolic products of CCC were measured using ion trap electrospray ionization mass spectrometry (ion trap-ESI-MS/MS). Determination of CCC or its metabolites in eggs and meat showed that CCC was metabolized to choline. Corresponding MS/MS spectra were obtained for m/z 104 (choline) or 105 ((15)N-choline), whereas nothing was detected at m/z 122 (CCC) or 123 ((15)N-CCC). The results from this study indicate that CCC will be metabolized in tissues of laying hens.
When (14)C-labeled CCC was applied to kohlrabi, cauliflower, or tomatoes, degradation of CCC was very small. The first product was probably choline which entered the plant pool. Small amounts of labeled methyl groups from choline were found as S-methyl methionine. CCC was not degraded when applied to sugarcane. In alfalfa, CCC was slowly metabolized and was primarily incorporated into choline of phosphatidylcholine.
Almond seedlings were treated with labeled CCC. Translocation to leaves and to the roots was observed. (14)CO2 was formed within 2 h after application. Radioactivity was observed in 17 known amino acids, an unidentified ninhydrin positive compound, malic acid, citric acid, choline and 2-chloroethylamine.
When CCC was incubated in rumen contents or juice under anaerobic conditions, microbial degradation of CCC did not occur.

Chlormequat chloride appears as white crystals with a fishlike odor. Used as a plant growth regulator. Said to be effective for cereal grains, tomatoes, and peppers. (EPA, 1998)
Chlormequat chloride is an organic chloride salt comprising equal numbers of chlormequat and chloride ions. A gibberellin biosynthesis inhibitor, it is used as a plant growth retardant to produce plants with sturdier, thicker stalks, facilitating the havesting of ornamental flowers and cereal crops. It has a role as a plant growth retardant and an agrochemical. It is an organic chloride salt and a quaternary ammonium salt. It contains a chlormequat.
A plant growth regulator that is commonly used on ornamental plants.

Mechanism of Action
Chlormequat chloride has been reported in the literature to act at the nicotinic receptor site of the neuromuscular junction. The test material may act as a depolarizing agent at this site, leading to muscular excitation followed by muscle weakness. Acute toxicity may lead to respiratory arrest. Acute toxicity of chlormequat chloride has also been reported to differ by species, which is likely due to sensitivity to depolarizing neuromuscular blockers.
