Asset rotation and good practices, the keys to the control of resistant weeds
From Agrofina they recommend betting on Alana, their new green band herbicide that uses two different modes of action. In addition, the firm launched two graminicides.

The control of resistant weeds is one of the issues that most interest the producer. And that was noticed in the Aapresid Congress, where companies took their products to ensure a campaign with good results while maintaining the commitment to environmental care.

Such is the case of Agrofina, which has one of the widest pallets of herbicides on the market, which launched three products: Alana, a pre-sowed green band herbicide for the cultivation of soybeans for the control of red yuyo and black branch; and two graminicides, which carry a higher concentration that allows the application of a lower dose, which translates into 150 tons less plastic drums in the environment.

In dialogue with Infocampo, Agrofina Development Manager, Lisandro Guerrieri, stressed that the important thing to fight resistant weeds is to “rotate assets”, so Alana is an excellent option, since it uses two different modes of action.

“We also have to look for tools that are not chemical, such as crop rotations, service crops, row spacing, cultural practices, see planting dates. There are many aspects to consider”, Guerrieri said in relation to Good Practices.

The firm advances in solutions for the rye grass resistant, which is estimated to be present in about 3 million hectares. “For that, we have an already positioned product that we will launch next year, which is actually a registration extension. It is a mixture of imidazolinones”, said the manager.

In the south, the important weed is the resistant turnip, for which Guerrieri recommended Talis, with flurochloridone, which works very well.

“In parallel, we have been working on new weeds, we see that today there are 36 resistant biotypes. The black branch advance is being suspected”, he said. By Marina Friedlander.
