Chlorocholine chloride (also chlormequat chloride or CCC ) is a water -soluble ammonium compound.

Use

As phytohormone chlorocholine chloride found in cereal production ( in fruit farming no longer permitted ) conventional agriculture use. It promotes cell division and thus strengthens the fruit wood young fruit trees. On cereals, it acts halmverkürzend and vessel wall reinforcing, so that it increases the stability of the plant against wind and precipitation.

The application to crop fields is preferably carried out in the spring, the amount is from 0.3 to 1.5 kg per hectare in 40 to 60 days wait time for new application (recommended by ' Bayer CropScience ' for Germany, product CCC720 ).

Health

The growth regulator since 1967 detectable in fruits, grain, straw and flour and possibly impair the fertility of ruminants and horses or rabbits. Chlormequat is considered genotoxic and disrupts the neuromuscular conduction, but does not carcinogenic according to previous research. In German fruit and vegetable growing, he is no longer permitted, but finds further use in cereal crops.

From the WHO Permissible a daily dose of 0.05 mg / kg body weight was established for baby food 0.01 mg / kg. The lethal dose LD50 orally in rats is 400 mg / kg body weight.

Chemical Properties

Chlormequat chloride is a white solid and a derivative of chlormequat. decomposes above 239-245 ° C, among others, in hydrochloric acid and trimethylamine. It is a white to yellowish hygroscopic powder with a characteristic odor.
