Weeds, a social dilemma

A recent study developed by ADAMA Argentina and FAUBA shows the meaningful economic impact of resistant weeds in argentine farming, and sets it as a social responsibility.

 

ADAMA Argentina and FAUBA published the main conclusions of their common research- “The economic impact of resistant weeds in argentine farming”- in Aapresid´s Conference.

Luis Mogni and Hernán Palau (both from FAUBA) presented the main conclusions and left an important message: “It was the whole productive system that caused weed´s problems. Now we have the common responsibility to solve it”.

The name of Aapresid´s event referred to a new existing sensitivity. Most important conclusions named to change our way of thinking. Weeds were clearly in the agenda.

 

“When do we have to act?”, asked Pablo López Anido to the full crowded room in Aapresid. The first moments of the event were booked with weeds.

“We focus the discussion on prevention. It´s not the same to work on fields full of problems. Aapresid has to work on those which remain clean, and look ahead”, asserted Anido.

Net solutions

Team up locally to fight resistance. With that premise west regional of AAPCE gathered community members and  Adama was part of it.

 

To create a net of sustainable practices it´s the main sense of these meetings. It´s clear that weeds are in the center of farmer´s worries.

Private and public actors regarding agribusiness are united in this initiative in order to share knowledge, actions and solutions over farming issues.

Plan beyond this year

An intelligent weed management means long term thinking. Experts even recommend planning towards five years from now.

 

Diversity, practicality and knowledge define a field-specific weed control program.

 “Develop a full-blown plan that stops weeds before they germinate, and rotate chemistries and modes of action,” Jim Legvold says. “Decide the best way to deal with any escapes by weed and size.”

The Vincent, Iowa, farmer plans each field’s weed control based on rotating chemistries, weed population, crop safety and cost. 

Scout. “Do this at least once a week to know what you’re spraying for”, Legvold advises.

Scout once a week

Before the crop is established, during its presence in the field and after the harvest, scouting is the main job in order to make any decision.

 

To use a PRE herbicide or a postemergence one, to mix products, to take a chance with cover crops… not any decision can be made without scouting first.

It´s part of an intelligent weed management to frequently walk your field, and take notes of what you observe.  This practice will make your future planning easier and more accurate.

Systemic thinking

In times of weeds, an intelligent management is vital.

 

“Systemic thinking” is a scientific approach to know, explain and intervene over complex phenomenon. Agribusiness is clearly one and weeds have added extra complexity to attend.

We need this kind of approach just to understand the impact technologies have made over the years in our fields.  

Weeds have been a reaction to a reductionist view of agriculture. On the other hand, a systemic thinking has the power to change it all at once.

Overwinter

Our challenge this season is not to leave space for weeds to come.

 

It´s well know: on weeds we cannot give any advantage.  Land fallows prepare our fields for next crop and all of the sudden they are here. How do we prevent their appearance during winter season?  There are two big options.  

The first one is chemical land fallow, doing all the applications needed. Those will depend over the region, the year, and weeds present in the field.

The second option is to include winter crops for cover or harvest. Anyhow, we will be doing efforts so crops can compete with weeds.

How do we prepare our fields in Winter? Which are the most important weeds we should be aware of?

Not only cold comes with winter but winter weeds as well.  

Weeds specialist from INTA Paraná, Marcelo Metzler, says this is the very moment when questions about weeds management begin. “If you don´t take preventive measures next crops will be in trouble”, he advises.

An early control in the first stages of land fallow is crucial. It is essential to walk the fields, warmly dressed, so us to be prepared to manage winter weeds.

Numbers are raging, farmer’s equations get more and more complex, but there is nothing you can´t rebut with an intelligent approach. Not even weeds.

Leaning over this complex situation, the one that many farmers are facing all over the country, “Maleza Cero” comes with an initiative in order to bring solutions to weeds challenge.

To raise your hand in this cause means to be part of a community in their pursuit of daily and sustainable solutions towards weed’s problem. To read, to exchange experiences and knowledge, to be connected on social specific nets, in order to build together the best strategies: that´s the key.

Weed´s early summer

Out of calendar high temperatures are influencing crops, this days. How do weeds behave during this “fake” summer?  

 A recent study published by E. Sierra, a climatology specialist from BCBA, describes temperatures superior than normal and rainfall of different intensity in our region.

How does this situation affect crops and, more specifically, how do weeds behave during this “fake” summer?  

Albano Aranguren, from Adama Argentina, reports lots of farmer´s consultation. “They describe that fields are greening and say they´ve seen Amaranthus Palmeri plants from 7 to 10 cm”. “This little summer is allowing weeds to grow without noticing that we are facing just June”.
