Abstract
Slug populations can be controlled in minimum or no-tillage methods of crop production using .beta.-carboline carboxylic acids. These compounds and their analogs can be formulated into slug bait compositions for use in erradication of these crop pests. The compositions are extremely effective at luring slugs from crop plants to the bait as well as killing them.
Claims6
A pesticide composition for the erradication of slug pests comprising:
- a) an effective amount of a slug bait, sufficient to lure slugs and induce said slugs to feed, and
- b) a molluscicidally effective amount of a compound of the formula:
- ##STR2## where R.sub.1 =H or OH
- R.sub.2 =H or COOH
- R.sub.3 =H or COOH
- R.sub.4 =H or halogen
- R.sub.5 =H, halogen or OH
- R.sub.6 =H, halogen or OH
- R.sub.7 =H, halogen or OH
- R.sub.8 =H, halogen or OH
- and wherein represents a single or double bond, and further wherein no two double bonds are adjacent, and that the number of substituents attached to any atom possessing a double bond be limited to conform with valence requirements.
