Cleavers is a competitive climbing plant forming dense masses of tangled vegetation in crops and along fencelines and on waste land. In contrast, biological control offers a sustainable, long-term control option. Directed by Mj Dixon. The phytotoxic effects of auxin herbicides, including the quinoline carboxylic acids quinmerac and quinclorac, the benzoic acid dicamba and the pyridine carboxylic acid picloram, were studied in relation to changes in phytohormonal ethylene and abscisic acid (ABA) levels and the production of H(2)O(2) in cleavers (Galium aparine).

Spencer (ed.). Biological control can be cost effective, environmentally safe, self-perpetuating, and well suited to an integrated weed management program. severe infection    Control In gardens and waste places, cleavers are easily destroyed by cultivation or simply pulling the plants out because of the brittle stems and shallow root systems. The leaves are in whorls, in groups of 6-8. Biological control of aquatic Diptera. To date, laboratory and greenhouse experiments have demon-strated that several fungal isolates provide effective weed control and are safe to major crops.
