Bayer presented last week the first results of its Credenz soybeans with LibertyLink (LL) technology in Brazil.
AgroPages was invited along with a select group of growers who visited the fields where the about to be harvested crop of Brazilian soybeans grown with the LL technology stood. The technology was launched last year and is positioned to become the major weed control alternative to control resistant weeds.
Nearly 400 of the most representative Brazilian soybean growers were invited to plant seven varieties of Credenz soybean with LibertyLink technology in the main regions of Brazil.
Preliminary results pointed out that the productivity was higher than the regional average. In Santa Catarina, for instance, the crop yielded 85 bags per hectare while in the states of Rio Grande do Sul, Mato Grosso and Goiás, the averages were between 72 and 74 bags per hectare. In comparison, Rio Grande do Sul (third top soybean producer in Brazil) reported an average yield of 50 bags per hectare in the last ten years.
“The LibertyLink technology came as an alternative to the producer who has been facing the growing problem of resistance and tough-to-control weeds,” explained the marketing manager of soybean seed, Filipe Romano.
According to him, the technology LibertyLink also has the benefit of preservation of Bt (Bacillus thuringiensis) technology. “When the LL soybean is planted in association, or along with, a BT area, it helps in managing insect resistance, because it works as a refuge area.” This is because the insects created in the area of this new technology are susceptible to the control of Bt area, and will end up generating new individuals susceptible to cross with resistant insects, thus leading to both technologies working side by side.
Romano explained that there less application and less quantity of pesticides helps farmers profit. “Farmers have increased the number of applications with glyphosate dose, but it leads to more cost makes operations complex. The LibertyLink technology has not encountered any case of resistance in Brazil. As a result, a farmer can apply as much as his initial glyphosate usage, that is, one application,” he said.
