No rea­son to worry about ex­tra poi­sonous pests

Central and North Burnett Times - - LIFE -

NORTH Bur­nett Re­gional Coun­cil mayor Rachel Cham­bers has re­sponded to con­cerns about the use of chem­i­cals which could make no­to­ri­ous pests cane toads more ven­omous.

Hun­gar­ian re­searchers have dis­cov­ered that the pres­ence of glyphosate, a chem­i­cal com­monly found in back­yard weed killers such as Roundup, in­creased the amount of poi­son tad­poles pro­duced when they de­vel­oped into toads.

Cr Cham­bers said the coun­cil did not use the chem­i­cal and thought it was in­ter­est­ing that it could have such ad­verse re­ac­tions on the cane toads.

“(The) coun­cil uses glyphosate and other her­bi­cides in the man­age­ment of recre­ation as­sets and de­clared weeds,” Cr Cham­bers said.

“Over­all, (the) coun­cil would be a mi­nor con­sumer of glyphosate in com­par­i­son to the agri­cul­tural and do­mes­tic sec­tors. The sub­ject study fo­cuses on tox­i­c­ity lev­els of toads de­vel­op­ing as tad­poles in aquatic sys­tems ex­posed to the sub­ject chem­i­cal.”

Cr Cham­bers said the coun­cil used other meth­ods for get­ting rid of pests.

“Coun­cil does not gen­er­ally use her­bi­cides on wa­ter-based plants, gen­er­ally re­ly­ing on me­chan­i­cal meth­ods in sen­si­tive ar­eas,” Cr Cham­bers said.

“There are how­ever emerg­ing trends in new her­bi­cides for use in aquatic sys­tems and con­tin­u­ing re­search and use in bi­o­log­i­cal con­trol meth­ods.

“Whilst the ar­ti­cle on the toad re­search is in­ter­est­ing, there is lit­tle im­pli­ca­tion for (the) coun­cil.”

Cane toads use the venom glands on their back to pro­duce co­pi­ous amounts of venom, to ward off any preda­tors.
