The state of Rio Grande do Sul, one of the largest soybean producers in Brazil, has suffered from several cases of drift, after the application of the herbicide 2,4-D on crops.
Due to incorrect methods of spraying, the product devastated other crops in nearby regions, such as grapes and apples. To solve this problem, a “Normative Instruction” was issued, which ordered the launch of training programs related to applicators and other relevant measures.
As a result, the booth of the “Deriva Zero” project was launched at Expointer 2019. AgroPages visited the booth and talked with its representatives.
“Drift Zero is an initiative that emerged this year, due to the need to make farmers aware of the consequences of applying pesticides. Our booth at Expointer is managed by Senar (National Service for Rural Learning), and aims to qualify and train farmers,” explained Alexandre Prado (Coordinator of Senar Special Programs).
“These requirements came from the Normative Instruction of Rio Grande do Sul State, which requires an agrochemical applicator to be registered with the State Department of Agriculture. Any farmer applying a herbicide that has a hormonal active ingredient, such as 2,4-D or Dicamba, needs to register their applicator,” Prado added.
The project aims to encourage training in the use of applicators to apply herbicides. Farmers are only able to register with the government after completing this training.
“Here at Expointer, we are highlighting the effects of the incorrect application of herbicides without using the appropriate equipment and the best application techniques. These include controlling boom height, spray volume and droplet size, as well as various nozzle types, which are all factors that affect whether or not drift will occur during application,” Prado further added.
“We are also encouraging farmers to consider the weather when applying hormonal herbicides. The wind must be below 10 kilometers per hour, the temperature below 30 degrees Celsius, and the relative humidity under 55%. All of these factors must be taken into account before spraying to prevent drift,” he stressed.
“Drift is a serious problem in the state of Rio Grande do Sul, but we are facing it. We are confident that people, if well trained, can improve the situation and their processes. We always said that the problem is not 2,4-D, because it has already been evaluated, approved and registered by regulatory agencies, such as Avisa, Ibama and MAPA. When people are trained, they will be able to solve the issue,” he said in conclusion.
