Weeds in the core area

During the last National Weed´s Journey, agronomist Juan Carlos Papa focused his speech over weeds in the core agriculture area of our country.

“Is it true that we are facing resistances and tolerances, at the same time. But more important than the problem´s solution, it is its formulation. On the other hand, we´ll lose energy pointlessly”, he said. Papa pointed the evolution as the main cause: “Darwin said it all”. Evolution involves adaptation changes of natural environment but also artificial one.  Simplification of productive system comes with weeds. For worst, we work as fireman, always coming late”.  

«Weeds threaten our competitiveness»

It was said by the Minister of Agriculture, Breeding and Fishing of Argentina, Gabriel Delgado, during the last National Weed´s Journey.

With a remarkable organization, gathering more than 2000 people, INTA Oliveros accomplished the first National Weed´s Journey. Specialists in the subject covered all technical, agronomic and biological aspects of weed´s control. From the public field, the official input was largely expected and thanked.

Weed´s control earns US$ 8.800 million for argentine society

It is in terms of foreign exchange. The recent study developed by ADAMA Argentina and FAUBA about the economic impact of resistant weeds in argentine farming, keeps making noise.

“The control of resistant weeds avoids a potential loss of 17 million tons of soybean, resulting in earnings of 8, 8 thousand million dollars for argentine society. This is in terms of foreign exchange”. That´s one of the most relevant conclusions of the study: “The economic impact of resistant weeds in argentine farming”, developed by ADAMA Argentina and FAUBA.

A recent study developed by ADAMA Argentina and FAUBA shows the meaningful economic impact of resistant weeds in argentine farming.

ADAMA Argentina and FAUBA chose Expoagro, the biggest farm show in Argentina, to publish the main conclusions of their common research: “The economic impact of resistant weeds in argentine farming”.

Numbers spoke for themselves. And media was highly interested.

Weeds and soybean in “9 de Julio”

ADAMA sponsored a meeting in “9 de julio”.

 A farmer, member of an Aapresid´s Regional, offered his place for a meeting to talk about weeds. 120 people participated with special interest.   

“We have a productive system that creates weeds”, asserted Martín Marzetti, CEO of REM (Aapresid).

To avoid resistance, Marzetti referred to classical practices of crop rotation, cover crops, an integrated herbicide resistance management program, and “all the ones we can create”, he added. Marzetti suggested farmers should be creative  in their fields, searching for their own solutions.

Weed identification tech for the future

Online resources and apps offer in-the-field assessments.

It’s no secret that weeds remain a problem for growers today. Given this, experts say one of the first steps in successfully combating weeds is correctly identifying them so proper action can be taken.

Printed weed identification guides have been around for a long time, but a large number of resources can also be found online, thanks to the work of many different universities.

More recent, however, is the availability of weed identification apps that allow mobile device users to have immediate access to data for accurate, in-the-field assessments.

“The old standby of looking in a book to identify weeds isn’t going to be as effective anymore. Using mobile devices and apps, however, is now a much better crop management option today,” says Michael Koenig, the founder and president of Lone Tree, Iowa-based ScoutPro.

Rent and weeds

In times of negotiation, weeds are a key in the conversation.

  “Then, why should I keep working?”, José Luis Zorzín asks himself, showing the feelings of farmers he advises. They are facing a difficult equation.  Without a lower price of rent or some practice to face the increasing costs of activity, numbers are turning red. And weeds are part of this complex business situation.

Here in Argentina but also in USA, farmers are walking away from rental contracts and though it’s hard to quantify how solid this trend is, it’s no surprise that “2015 is going to hurt,” says Purdue Ag Economist Michael Langemeier.

“Producers don’t want to let farmland go that they won’t get back when things improve. Next year’s cash flow projections make them question how they’ll make it through the next few years.”

Think Like a Weed

To beat herbicide resistance, understand how it develops and spreads.

A proven method for understanding opponents is to put yourself in their shoes and see the world as they see it – in this case, to think like a weed. What do weeds need to thrive? What plant characteristics and cultural practices are beneficial to herbicide-resistant weeds? What management tactics have proven effective against them?

Weeds are plants out of place that compete with crops for light, moisture and nutrients in their efforts to flower, create seed and multiply. The nature of plants, whether desirable or not, is to produce seed to expand and prolong the species.

Learning to live together with weeds

Roberto Ressia had to change his business plans because of weeds.

 Roberto Ressia is a traditional farmer in Washington, in the south west of Córdoba’s province. A race from breeders was replaced there by agricultural practices, when no tillage system sprayed all over the pampa´s.  Ressia started working land belonging to his family, 2500 hectares, and business began growing. “We almost reached 10.000 hectares”. But 4 years ago they had to go back in business. Today they work 3500 hectares. “And we do it with the same structure we had before shrinking. That structure allowed us to fight resistant weeds”, he explains.

Roberto reached a goal, after all: “we learnt to live together with weeds in our fields”. The key, he says, “is to know which the damage threshold is”.

Community weed control

Farmers team up locally to fight resistant pigweed.

Think Different

Using a zero-tolerance approach to weed control, farmers can team up to battle resistant weeds along highways, turnrows and common areas that harbor weed reservoirs. For example, rainwater spreads pigweeds, making it a communal problem.

This approach has made a difference for Clay County, Arkansas, where farmers are fighting herbicide-resistant Palmer amaranth. It’s not uncommon here for a farmer to spend over $100,000 on herbicides – plus more on weed-chopping crews – and still have pigweeds, says Andy Vangilder, county Extension agent.

“Whenever a farmer is riding down the turnrow and sees a weed, he goes and gets it,” says Mike Morgan, a Rector, Ark., cotton farmer and weed fighter.
