Buenos Aires, July 23rd. In Mar del Plata city, in the heart of the most productive wheat region in the country, the New UPL presented its new fungicide, Tridium, created to protect barley and wheat crops from fungal diseases. “Tridium contains mancozeb, azoxystrobin, and tebuconazole; the multisite action mode of this latest active principle avoid the fungal resistance in the crops”, Andres Fabbris Rotelli, Insecticides and Fungicides manager from UPL told to the audience, composes by agronomist and farmers.

“It is an excellent proposal to include mancozeb in the formulation of Tridium, because of it difficult the appearance of resistance”, phytopathologist Marcelo Carmona said. In fact, Carmona was one of the researchers that found tan spot resistance to strobilurins. The researcher shown itself heavily worried due to the acceleration of damages caused by this fungal disease.

At its time, UPL’s country manager Rodrigo Ramirez announced that the farm surveillance network called RAVIT, will expand its operation from north of Cordoba province (where it monitors 1.5 million hectares) to the southeast of Buenos Aires province, where wheat is the most important crop. “The goal is to increase the knowledge generation velocity, through a change in the monitoring scale”, he told to the presents.

“When an only action mode fungicide is continuously sprayed, resistance is something that will occur, sooner or later”, phytopathologist Ignacio Erreguerena added. He agreed that the Tridium’s strategy, acting over various sites, helps to mitigate the appearance of the resistance.

Fungal leaf diseases cause 20% yield losses in what crops, and until 30% in barley ones. “We must try to avoid that occurring the same that occurred with herbicides”, Carmona explained, in reference to the glyphosate weed-resistance.
