Mechanism of action

Clopiralid and picloram have a systemic effect, easily penetrate the plant, mainly through the leaves (but maybe through the roots); quickly spreads throughout the plant, including the root system, blocking the growth points of meristematic tissues. The action of the herbicide is based on the auxin type reaction. Being a synthetic form of natural plant hormones, clopyralid and picloram replace the plant’s natural hormones, blocking their functions. Oversaturation with synthetic hormones leads to disruption of growth processes and plant death. Destroyed both the ground part and the root system of weeds, including the buds 

Range of action of the drug

The drug based on clopyralid and picloram is used to destroy annual and perennial dicotyledonous weeds, including those resistant to 2,4-D and 2M-4X, mainly from the family Asteraceae and buckwheat: chamomile, field sow thistle, field calf, Tatar lettuce, dandelion, thistle, mountaineer, buckwheat, bindweed, etc., in rape crops. Successfully destroys dicotyledonous weeds, such as thistles, chamomiles, cornflowers, and godson, the most problematic rape crops.

Визуальные признаки и скорость воздействия препарата

Sensitive weed growth stops 2 hours after drug administration. Visual symptoms of the lesion (stunting, deformation of the leaves and the stem) appear 2-5 days after the application of the herbicide, and complete death, depending on the type of weed and weather conditions, after 2-3 weeks.

Compatibility with other drugs

Meridian can be used with preparations based on haloxifop-R-methyl (in case of clogging of crops with wheat grass creeping), with some insecticides, fungicides, liquid nitrogen fertilizers. It is not recommended to mix Meridian with growth regulators.

The influence of environmental conditions on the effect of the drug

The drug is recommended to be used when the average daily air temperature exceeds +8 о С.

Processing should not be done before frosts or immediately after frosts.

Precipitation 1-2 hours after the use of the drug does not affect its effectiveness.

Recommendations for the introduction of the drug

The meridian is characterized by a wide range of possible application periods: from the phase of 3 true leaves to the appearance of flower buds in rapeseed, the size (diameter) of which should not exceed 1 cm.

The maximum effect is achieved when processing young, actively growing weeds. Annual weeds should be in the 2-6 leaf phase, and perennial root weeds in the rosette phase. In the fight against tenacious weed – one of the most problematic weeds in rapeseed crops, the treatment is most effective when the weed height is up to 8 cm. With a weed height of 9-15 cm, the drug inhibits the growth and development of the bedstraw, which remains in the lower tier of the crop, does not form seeds and does not pose a threat to the crop and the quality of rapeseed.
