The launch of Paxeo, a product that is part of the new family of triazolopyrimidine sulfonanilides herbicides, was announced recently.
According to the manufacturer Corteva, it is a systemic herbicide with a residual effect, combining two action mechanisms recommended in soybean pre-sowing.
“It is the first member of a new family of synthetic auxin-based herbicides developed by Corteva. It is an innovative solution for controlling Conyza bonariensis and other resistant and tolerant weeds,” the agrochemical multinational said.
The product also offered “long-lasting weed control Digitaria insularis, Commelina virginica, Ipomoea acuminata and others.”
In addition, Corteva highlighted that Paxeo has “eight macro benefits of Arylex active technology”. The product results from more than 10 years of studies and approximately 500 areas of research and development.
Among the advantages of this new technology are "superior control in drought conditions, desiccant action with greater residual control, new family of herbicides - ideal for controlling resistant weeds, greater control with ultra-low volatility, and less phytotoxicity for non-target crops, in pre and post-emergence, without antagonism in association with graminicides and flexibility in the application - from 7 to 50 days before planting."
For Corteva, “trust is essential when managing the field, but the antagonism between herbicides and graminicides is a frequent difficulty for the producer. And, often, he faces double problems with Conyza bonariensis in the same area.”
According to data from Spark Smarter Decisions Consulting, more than 80% of the area is covered with horseweed and has bitter grass.
According to Supra Pesquisa, it takes only five horseweed plants per m² to cause losses of up to 33% in the harvest and four bitter grass plants per m² to generate a loss of up to 43% in productivity.
