Brazil state growers apply excessive agchems

Growers in Brazilian state of Rio Grande do Sul routinely carry out unmonitored aerial spraying of pesticides, newswire Agrolink reports. It cites survey data from 2013/14 on the degree of IPM adoption that were presented at the recent 37th Rio Grande do Sul Expointer conference on agricultural technology. They further reveal that growers unconditionally raise application rates, fail to adopt crop rotation and “blatantly exploit susceptible crops”. State technical agricultural aid agency Emater agronomist Alencar Rugeri claims that application rates of pesticides are rising due to a lack of monitoring and specialist assessments of earworm (Helicoverpa armigera) controls on cotton, maize and soybeans. Plant health department DDSV chief Vinícius Grasselli says that retailers are pressuring sales for “unnecessary” applications.
