Expointer 2017: Dow AgroSciences launches ‘Out Fleabane and Sourgrass’ movement
Sep. 6, 2017
By Leonardo Gottems, reporter for AgroPages
During Expointer 2017, Dow AgroSciences launched the “Out Fleabane and Sourgrass” movement, a campaign to engage the bodies involved in the production and sale of soybean in a discussion about last year’s crop losses, due to weed infestation.
Expointer 2017, one of the largest agricultural fairs in Brazil and also in Latin America, which was held in Esteio, Rio Grande do Sul from August 26 to September 3. AgroPages attended this fair with its latest published bilingual magazine (English & Spanish) –2017 Latin America Focus.
Currently, the largest issue facing soybean growing areas is the presence of weeds that are resistant to glyphosate. However, fleabane and sourgrass cause the greatest problems to soybean crops because of their widespread range and their resistance to glyphosate. The movement aims to highlight the losing yields of Brazilian producers due to this problem.
“The idea is to explain the current situation around matocompetition, and discuss its agronomic, operational, environmental and economic impact, as well as the potential damage while eliminating the problem,” stated Marcus Fiorini, Marketing Leader for Major Crops at Dow AgroSciences Brazil.
According to Fiorini, the weeds are a major problem and have the potential to spread out of control, and they reduce the yields of the farmers and can negatively impact other Brazilian crops in many ways, including risking the use of good environmental and agronomic practices such as the “no-tillage system.”
“These weeds can easily spread and adapt, mostly because of Brazilian agricultural systems which do not promote crop rotation and soil management, as is the case with soybean crops using the no-tillage system. This occurs because fleabane and sourgrass produce seeds that are very light and can be spread by the wind over long distances,” added Fiorini.
Recent studies by the Brazilian Agricultural Research Company (Embrapa) about the economic impact of weed resistance to herbicides in Brazil pointed out that the total surface area in Brazil infested with herbicide-resistant fleabane is estimated to be 8 million hectares, costing the economy between R$970 million and R$1 billion.
The estimated total area infested with glyphosate-resistant sourgrass is 8.2 million hectares, while an area of 5.5 million hectares infested with sougrass will cost between R$1 billion and R$2 billion to control. The worst case scenario, in relation to costs, is the presence a combination of fleabane and sourgress, which is estimated at 2.7 million hectares, costing between R$793 million and R$1 billion.
“The ‘Out Fleabane and Sourgrass’ movement aims to highlight this serious problem of weed infestation facing our crops, which causes loss of productivity due to matocompetition. As well as serving as hosts for plagues and diseases, they also increase moisture and impurities in the harvested grains, which lowers the commercial value of each bag, leading to lower returns for the producers,” Fiorini stressed.
Through the website of the Out Fleabane and Sourgress movement - www.forabuvaeamargoso.com.br - soybean growers can find complete information about the correct way of implementing combined control management. The movement will also organise interactive training in several Brazilian cities.
