This group is known to be a pest of small grains and seedling production. This pest species has the potential to produce 60 eggs per clutch and as many as 40 clutches per year. This species is considered a significant agricultural contaminant of small grains due to sheer numbers of snails that occasionally aggregate on the crop. They cause significant economic losses to farmers as their aggregation on crops clog and damage machinery during harvest. The presence of large numbers of snails in harvested grain elevates the moisture content and promotes secondary infestation by fungal pathogens that produce toxin in the grain. Toxin contaminated grain is unmarketable, as it is not fit for animal and human consumption. Multiple countries have rejected shipments of grain from Australia due to contamination by this species.
