Spraying pesticides and anything other than organic manures is forbidden. The presence of this slug proves so. Although slugs and other similar faunas can rid a plant of its buds soon, they are essential in several ways.
Slugs are one of the most destructive and difficult pests to control. Seedlings of many vegetables and flowers are favored foods, and high populations of slugs can cause difficulties in establishing a crop. Slugs also feed on many fruits and vegetables prior to harvest. This preharvest feeding results in wounds that allow various fungi and bacteria to enter and spoil the crop. In addition, the slime trails produced by slugs can contaminate garden produce.
Slug injury is sometimes difficult to diagnose because slugs hide during the day. Smaller leaves may be eaten entirely, while only the edges of larger leaves may be consumed. Thick leaves often are rasped from the leaf underside. The presence of slime trails often is the best indication of slug activity.
