Perennial weeds are capable of thickening cultivated plants, thereby causing significant harm when growing them. Selective herbicides are used to destroy them.

What are the consumption rates and method of application for this drug, safety precautions, can it be combined with other drugs, how should the agent and its analogues be stored.
Active ingredient and preparative form
"Bis-300" contains clopyralid as an active substance, which can hold 300 g in a liter of the drug. The manufacturer - LLC "Agruskhim" produces this herbicide in the form of an aqueous solution. It is a systemic pesticide by the mode of penetration, by the nature of the action - an agent with a selective effect. The herbicide is produced in plastic cans that hold 5 liters of the substance.
Mechanism of action and speed of action
After spraying, the herbicide solution is absorbed into leaf tissues, transported to growth points, roots. Clopyralid is an artificially produced plant hormone. Its action in a weed plant leads to disruption and termination of growth processes and subsequent wilting.
