METHIOCARB AND METALDEHYDE AGAINST SNAILS INFESTING POTTED ORCHIDS, 2005

Summary of Methiocarb Trials against Pest Birds in Senegal

INTRODUCTION Several species of granivorous birds are responsible for damage to cereal crops in Senegal. Palearctic migrants, such as ruffs (Philomachus pugnax), godwits (Limosa limosa), and waterfowl damage newly sown rice seed or germinating plants. The main pests to ripening cereals are the red-billed quelea (Quelea quelea), black-headed weavers (Ploceus melanocephalus), village weavers (P. ...

Seed dressings to control slug damage in oilseed rape.

Slugs are major pests of oilseed rape that are poorly controlled by conventional bait pellets. A series of laboratory experiments investigated the potential of seed-dressings to control slug damage in this crop. Four compounds: metaldehyde, methiocarb, cinnamamide and 3,5-dimethoxycinnamic acid (DMCA) were tested at a range of doses for phytotoxicity and ability to reduce damage by Deroceras re...

The environmental profile of metaldehyde

Since 1937 the dry alcohol metaldehyde has been known to act as a molluscicide. Detailed studies have shown that the main effect on slugs is that the mucus cells are irreversibly damaged. Mucus cells are part of important physiological structures typical of molluscs. Metaldehyde is not phytotoxic and in no cases have negative effects been recorded on the carabid beetles Poecilus cupreus, Carabu...

aperture in the tissues surrounding the meristems. 'This simple experiment revealed that there were four distinct regions of the embryo with different plasmodesmata apertures. The shoot meristem had the highest aperture enabling movement of single-to-triple sized GFP; the hypocotyl (embryonic stem) allowed single, double and some triple-sized GFP movement; the root allowed single and double-siz...
