“Brazil needs dicamba technology” - Pedro Christoffoleti, PhD Professor at the University of São Paulo
Jul. 4, 2019
By Leonardo Gottems, reporter for AgroPages
In an exclusive interview with AgroPages, the professor Doctor of the University of São Paulo, Pedro Christoffoleti, stated that dicamba technology is absolutely necessary for Brazilian agriculture. He was one of the experts invited by Bayer for the I2X Talks event, held in the city of Campinas in the state of São Paulo.The meeting brought together experts, consultants and researchers in the area to talk about the great issues that surround soybeans, with emphasis on the themes that make up the mandala of the Intacta 2 Xtend platform: State-of-the-art biotechnology/ample weed control/high efficiency against caterpillars/advanced genetics and intelligent management.
Christoffoleti also presented the results of studies conducted after the first year of testing of the new biotechnology in experimental fields in the South American country.
In your presentation during the event, you said that dicamba is a great alternative that Brazil will gain from the Intacta 2 Xtend technology. Why did you come to this conclusion?
It is a pleasure to speak to AgroPages. I made this claim based on several tests we conducted in our experimental station. Today, the problems with broad leaves in Brazil are increasing by the day. And when I say problem with broad leaves, they are broad leaves that are being selected, or resistant to glyphosate, or broad leaves that glyphosate has difficulty controlling.
And many of these broad leaves are also turning to alternative herbicides, notably ALS inhibitors such as chlorimuron, for example, as well as Protox inhibitors, and the inhibitors of photosystem. So, alternatives to controlling these leaves are becoming increasingly scarce and Dicamba, an oxynic herbicide, a herbicide specialized in the control of broad leaves, is certainly an interesting alternative.
The soybean Intacta Xtend RR2 allows the dicamba to be used selectively within the crop, with total selectivity. So, by the time he has this technology available, the producer is going to have a very interesting tool to deal with those broad leaves.
You also mentioned an increase in the residual effect. What gains can the producer see with this?
Many people do not know, but dicamba, although it is a herbicide of post-emergence application, if applied to the soil, it has an effect on the soil; it is not simply used as a residual, but it can act in assisting other residuals. It offers a residual gain to the residual herbicide itself.
So, for example, associating dicamba with flumioxazin, or imazethapyr gives a greater residual to these herbicides, coupled with their post emergent effect. Therefore, in addition to offering post-emergence action, the product that eventually falls to the soil will also have an effect on the soil.
