Slugs and snails
Slug and snails are particularly damaging at the early stages of crop establishment affecting plant seeds (mainly legumes), seedlings and leaves.
Much less is known about slug and snail damage to established pasture and how they can limit pasture persistence. Pasture systems that depend on clover to increase milk yield and for nitrogen fixation might be affected by slugs.
Stages of monitoring and control strategies
- January to February - Assess stubble management options for slug and snail control
- March to April - Assess options for burning and/or baiting
- May to August - Assess options for baiting, especially along fence lines
- Tilling less and maintaining stubble allows slugs and snails to increase in numbers
- Stubble grazing in summer may reduce the number of slugs and snails by trampling and destroying their refuges in paddocks prior to resowing
- Early detection prior to seeding is ideal as there are more control options available
- Pasture systems that depend on pulses and clover might be particularly affected by slugs and snails
