Growers of pulse crops selling to export markets should be wary of being caught out by exceeding pesticide MRLs (Maximum Residue Limits) set in the countries buying their produce, according to Queensland Department of Agriculture, Fisheries and Forestry senior entomologist Mr Hugh Brier.
Mr Brier said MRL restrictions could vary significantly from country to country. He said it was vital that all growers helped protect export and domestic markets by not exceeding pesticide label rates.
Producers need to observe pesticide withholding periods and use patterns (e.g. only one spray per crop), and only use pesticides registered or under permit for the crops in question.
“People should work very closely with the people buying their beans and exporting their beans overseas, as particular markets may have restrictions that we don’t have here, and their traders should be aware of that,” he said.
Also consider exclusion zones around crops being sprayed. Spray drift onto adjacent crops or pastures could result in MRLs being exceeded in products from these enterprises and product being rejected, in other words unintended collateral damage.
