Notícias Agrícolas spoke with Leandro Paiola Albrecht, a researcher at UFPR, to address a problem that is recurrent in soybean farming: horseweed. However, the arrival of a new solution could bring a new fight to this problem.
There is a new herbicide arriving in Brazil: dicamba. As herbicides such as paraquat and glyphosate have already generated resistance in some cases, as a result of misuse, dicamba could be a solution to this issue, but care must be taken.
For Albrecht, producers have to create routines and habits to use the herbicide correctly and not lose this technology. His recommendation is that the application be made 30 days before soybeans and also post-emergence, on top of soybeans.
He says you have to be careful with resistance. The horseweed plant generates around 350,000 seeds that spread very quickly with the wind. If your neighbor also has soybeans, you should be extra careful.
However, believing in the performance of the product, which already has good results in the United States, the producer can carry out good control. The use is a minimum volume of 150L per hectare and application should be avoided in windy times. The ideal is also for the plant's physiology to be active.
