The drug includes 200 grams per liter of 2-ethylhexyl ether, 3.7 grams per liter of florasulam. Primadonna is produced in the form of an emulsion suspension, packaged in five-liter canisters.

How does the product work?

Florasulam slows down the production and synthesis of amino acids in weeds. Acting inside the acetolactate synthase enzyme, it perfectly performs this task. The 2nd element – ​​2-ethylhexyl ether – helps suppress weed growth hormone.

Thanks to the coordinated work of 2 elements, the effect of using the product can be noticed after just a few days. During this time, the elements of the herbicide are distributed throughout all parts of the grass, preventing cells from developing in young tissues. The weeds finally die after 2-3 weeks.
