Antonio Deane, a well known climatologist, speaks up about El Niño and its consequences over commodities market.

“It´ll be like living in a tropical región”. A tropical environment will bring us tropical weeds, brought by birds and wind.

On the other hand, referring to diseases, he says the tropical climate will bring special refuge for fungus. And the same goes for insects.

Pioneer in Argentina over weed´s issues, Conyza has finally got its label as a resistant weed, in Entre Ríos province.


Till now, none of both species of Conyza were declared resistant, although it was well known they both were.   Eduardo Puricelli, Delma Faccinni, Federico Balassone y Marcelo Metzler, from UNR and EEA Paraná from INTA, obtained the curve dose- respond for glyphosate herbicide in Conyza sumatrensis and Conyza boneriensis. Both biotypes were gathered in Paraná, Entre Ríos.

The founded biotypes of both species were declared resistant to glyphosate.

Malezas 2015 was the first argentine experience of the Latin American Weeds Congress and it was a real success.


“Malezas 2015” was the 22nd experience of Latin American Weeds Congress (ALAM) and the first time Argentina was the host country.  

The local edition focused on the actual knowledge about weeds and on everything related to innovation and actual problems in productive systems.

Santiago Zuberbuhler CEO of Kleffmann Group analyzed Argentine´s weeds issues.


Argentinean farmers are constantly pushing the boundaries of arable land. The overall treatments applied to protect their crops represent a growing market valued today at some $2.5 billion in agrochemicals alone. Almost 65% of that value is targeted at weed control.
In the next couple of years, the R&D pipeline will deliver new technologies, and a new generation of young, more highly educated farmers will be in place to use them. This combination of technology and young educated farmers provide significant opportunities to create new products and agronomic platforms that help production systems evolve based on sustainability for both technological and ecological resources.

Farmers and agronomist of diverse productive zones reveal their saving strategies, without diminishing weed´s control.


Esteban Bilbao, a farmer from Necochea city, in the southeast of Buenos Aires, says this year technology costs are being left aside. But he also asserts t that leaving rotation aside comes with negative consequences, as for example weeds.  

Juliana Albertengo goes the same way: “to take risks on plagues and diseases, makes everything worse”.

Forth edition of JUCsA, left clear that weeds are a huge challenge for future agronomists.

FAUBA organized a new edition for agronomy students. “We understand that JUCsA cannot be appart of constant social and productive changes. Future agronomist must be in constant learning experience”, explained Rodolfo Golluscio, Dean from FAUBA in the opening lecture.

Weeds were, of course, a nuclear part of the program.

It´s usual to observe this days many productive areas not having their land fallows. How do we explain it? And what will be the consequences?


Something rare in the past seems to be the rule this season. Why is this happening? What will be the consequences?

Economic situation is quoted as the main reason. But the real cost of inactivity is huge. This high rate of acres without their chemical land fallow will impact on the yields and will higher costs of production, a clear disadvantage for season to come.
