The University of Melbourne's Dr Michael Nash says slug trials in the past year have shown baiting is still the best option for chemical control and grain growers should not skimp on bait rates... Dr Nash says growers must closely monitor crops after rain when conditions are moist and favourable for slugs, particularly in areas affected by the pests in the past... Speaking at the recent GRDC Adviser Updates series in the southern region, Dr Nash says baiting success depends on the chances a slug will encounter individual baits, which is influenced by slug activity, attractiveness of the bait and the number of baits...

Slugs best beaten by baiting at sowing.. The planter was mounted with a bait applicator to apply slug bait in a 10-centimetre band directly above the row at seeding... To monitor slug numbers in spring and then at pre-sowing, Dr Nash says it is easier for growers to put down some cheap bait, leave it overnight and come back the following day to see how many slugs were killed, rather than using surface refuges such as tiles...
