Proactive pest control pays dividends

Published on 11/11/2019

But when it comes to one of the most common pests that affects spring sown crops and pasture, it’s always better to be proactive rather than reactive, especially in direct drilling situations.
While there are many species of introduced slugs in this country, the grey and brown field slugs cause the most damage to crops and some pasture.
According to Paul Addison, technical specialist for Nufarm, the wet spring and summer set up perfect slug breeding conditions in several regions, with farmers already reporting serious damage to emerging crops.
Once a problem does become apparent, a lot of damage may have already been done that cannot be reversed, he says, and slugs can make a mess of newly sown crops or grass in a matter of days.
“The price for getting it wrong is just too high, especially when you’re looking at the overall investment required for sowing a paddock of new grass or crop.”
Addison says there are several types of bait available.
However, if farmers want to protect beneficial predatory beetles – which help control slugs in the paddock – baits containing methiocarb should not be used, because they cause secondary poisoning.
Metaldehyde, the active ingredient in SlugOut, is not harmful to earthworms, either; poisoned slugs pose no threat to birds or
small mammals.
Another key consideration in picking the right slug control is coverage, or the number of bait points per square metre, Addison advises.
“Industry research has repeatedly reinforced the importance of coverage in obtaining effective control where high numbers of slugs are present, most recently in the Foundation for Arable Research’s latest Integrated Pest Management guide.
“This is where SlugOut comes into its own,” he says.
“At the recommended label rate of 10 kg per ha, FAR trials show SlugOut has 112 bait points per sq metre, which is much higher than other baits with the same active ingredient.”
He strongly encourages checking paddocks before sowing, leaving out sacks or boards for two or three nights to find out if slugs are present.
Bait should be automatically used in all no-till situations, because not cultivating creates ideal conditions for survival. If cultivated seed beds are cloddy, farmers should monitor and consider baiting.
SlugOut All-Weather Slug and Snail Bait was jointly developed in New Zealand by Nufarm and AgResearch.
It combines excellent weatherability, mould resistance, palatability and efficacy - the unique Corbie Technology of SlugOut concentrates the metaldehyde in the outer part of the bait ensuring a lethal dose is rapidly ingested by slugs.\
