Diva rids grain and corn fields of resistant weeds
Composition and release form
The herbicide is a systemic agent. It contains 200 g of 2-ethylhexyl ester and 3.7 g of florasulam per liter of substance. Presented on the market in the form of an emulsion suspension. Sold in plastic canisters, in five- and ten-liter volumes.
Active ingredient of the herbicide Primadonna
The drug is a combination of two active components with different mechanisms of action.The ester in the pesticide Primadonna acts as an auxin-like inhibitor, and the active substance florasulam inactivates the enzyme acetolactate synthase and acts as a paralyzer of the biosynthesis of essential amino acids. Thanks to these actions, the drug successfully helps to get rid of such annoying weeds as ragweed, knotweed, poppy, dandelion, sow thistle, damask, chamomile, shepherd's purse and others.
The drug immediately begins its work. Within 60 minutes after treatment, the solution spreads to all parts of the weeds, disrupts their cell division and leads to partial death of the grass the very next day. After half a month it dies out completely.
