Chitosan in Plant Protection
Chitin and chitosan are naturally-occurring compounds that have potential in agriculture with regard to controlling plant diseases. These molecules were shown to display toxicity and inhibit fungal growth and development. They were reported to be active against viruses, bacteria and other pests. Fragments from chitin and chitosan are known to have eliciting activities leading to a variety of de...

Rabea E.I., Steurbaut W. (2010): Chemically modified chitosans as antimicrobial agents against some plant pathogenic bacteria and fungi. Plant Protect. Sci., 46: 149–158. The antimicrobial activity of eight chemically modified chitosans against plant pathogenic bacteria of crown gall disease agrobacterium tumefaciens and soft mould disease Erwinia carotovora and fungi of early blight disease al...
متن کاملPlant protection with inorganic ions.
Gradients of salts of the specific ion repellents for Meloidogyne incognita -- NH, K, Cl, and NO -- have been demonstrated to shield tomato roots from infestation in soil. The strategy of these greenhouse experiments was to interpose a salt barrier in a soil column between the plant roots and the nematodes. The relative effectiveness of the salts as a barrier to infective second-stage juveniles...
متن کاملQuality Control of Plant Growth, Plant Protection, and Quarantine
The development and use of many efficient and economical pesticides, since the 1940s, have permitted unprecedented crop and animal protection, and improved public health. Despite the positive effects mentioned above, many problems arose, such as the destruction of other pests in addition to target pests, destruction of natural enemies, pest resistance, and the health hazards caused by pesticide...
متن کاملChitosans for Permanent Antimicrobial Finish on Textiles
Surface chemistry and structure determines most uses of textiles (adhesion, skin contact, handle ...) whereas the fibre core has to give strength. Thus, new strategies have to be developed for imparting permanent functionality to textile surfaces. This aim can be reached by using e.g. biocompatible polymers like carrageenans, chitosans from the carbohydrate family or some of their derivatives f...
