Abstract

Background: 2,4 Dichlorophenoxyacetic acid (2,4-D), the second most used pesticide in Brazil, has high volatility and solubility in water, which allows it to easily enter the atmosphere by drift, volatilization, leaching or runoff, resulting in damage to sensitive crops, causing malformations in leaves and fruits, as well as the death of many plants.

Objective: This article aims to examine the context of the conflict in agribusiness between soybean producers and grape producers in the Pampa Gaucho region, in relation to the drift of the pesticide 2,4-D and the damage to wine growing, describing the main initiatives of the Government of the state of Rio Grande do Sul in the face of the friction created, with the aim of observing whether the actions carried out by the State resolved the conflict.

Method: The research is exploratory and descriptive, using the deductive method and supported by literature review and documentary analysis.

Results: The normative instructions basically deal with oriented sales of hormonal pesticides, registration of properties and producers of sensitive crops, registration and training of herbicide applicators, reporting channel, inspection and obligation to report data on the application of the herbicide. 

Conclusions: The conclusions indicate that the measures adopted by the Government of the State of Rio Grande do Sul to mitigate damage to sensitive crops, up to now, are limited to inspection and the elaboration of normative instructions aimed at alleviating the problem, however without resolving it.
