Many of the signs point to Brazilian soy growers as those responsible for the spraying, in part because the indigenous community's land is valuable for the crop and that they had been in a dispute with the Ava Guaraní over the ownership of approximately 3,000 hectares , according to the blog Interparaguay . 
Ishara nyingi zinaelekezwa kwa walima maharage ya soya wa KiBrazili kwamba ndiyo wanaohusika na unyunyiziaji huo, kwani kwa kiasi kikubwa ardhi iliyo mikononi mwa jamii za wenyeji ingefaa sana kwa zao hilo na kwamba hawa wamekuwa katika mgogoro na Ava Guaraní kuhusu umiliki wa takribani hekta 3,000, kwa mujibu wa blogu ijulikanayo Interparaguay .
