Product information

Treated Plants: Rape, Beet, Vine, Onion, Spruce Nurseries, Wheat, Corn

Combat weeds: Cirsium arvense (creeping thistle), Sonchus spp (sowthistle), Senecio vulgaris (common groundsel), Matricaria spp. (wild chamomile), Polygonum spp. (spotted lady's thumb).


It is a systemic herbicide, post-emergent, used in combating dicotyledonous weeds of sugar beet, wheat, maize, onion, rape, mustard, live fruit, and forest nurseries. The active ingredient in the Lontrel 300 EC herbicide is clopyralid. Clopyralid is a pyridine carboxylic acid that is absorbed into the leaves and roots, thus determining the cessation of plant growth.

Lontrel belongs to Group 1 herbicides, together with 2,4 - D, MCPA, dicamba, picloram, triclopyr, and fluroxypyr which are disruptive to the growth of plant cells. This unique mode of action makes the Lontrel 300 EC herbicide ideal for use in control strategies and resistance against broad-leaved weeds.

Mode of action:

After the herbicide is applied it is absorbed very quickly and translocated throughout the plant, including at the root level, and accumulates in areas with increased metabolic activity. This translocation capacity makes Lontrel highly effective against perennial weeds with deep roots like thistles. The weeds concerned by this herbicide do not die immediately, but their growth is stopped.

Once translocated in all weed regions, clopyralid interrupts water absorption, nutrients, and plant metabolism. The leaves dry out and lose their functional properties, and eventually the plant dies, including the roots of depth.
