Ascenza launches Mesopec herbicide to control corn weeds

Controlling invasive plants has different results depending on the period in which this practise takes place. The best moment is when it is emerging, that is, as soon as the weeds appear in the cornfields. These invaders, which seem harmless, can cause several problems throughout the harvest, from development, in the production process, grain quality and even at harvest time. Furthermore, weeds can be gateways for pests and diseases. That way, the result can only be a loss to the pocket.

Thinking of an efficient tool for producers to use to resolve this situation, Ascenza, a Portuguese multinational belonging to the Rovensa group, has just launched Mesopec, a selective herbicide for post-emergence application. With systemic action, the new product is composed of Mesotrione 480 SC (concentrated suspension), with proven efficacy for controlling weeds with annual growth broad leaves and grasses in the corn crop.

The substance belongs to the chemical group of triketones and acts by interfering with the weed's development, causing the bleaching of these plants that are sensitive to the product and then necrosis and finally the death of plant tissues. This process takes about one to two weeks after applying the formulation.

According to Patricia Cesarino, agronomist and technical marketing expert, absorption of Mesopec happens through the roots, leaves and branches of the weeds. “That is why we say that it is a molecule with high mobility and efficient absorption. Remember that corn is tolerant to it due to its great ability to metabolize the herbicide rapidly. It is worth remembering that the product is indicated both for use in crops with the conventional planting system and in the direct planting system.” he explained.

Effective results

The active ingredient Mesotrione has been used for many years to control weed competition in corn. For example, according to a study carried out by Luiz Lonardoni Foloni, an agronomist and researcher at the University of Campinas, in 2002, this formulation has already provided excellent results, controlling from 90 to 100% of Digitaria horizontalis, or Capim Colchão.
