In recent decades allelopathy has gained much attention in the sustainable agricultural systems. It is necessary to trace out the mechanism of action of allelochemicals of plants on other plants. Allelochemicals of different plants interact differently with each other. In the present context an attempt has been made to study the influence of allelochemicals released by Parthenium on the growth,...

Cell-free filtrates of axenic or bacterized cultures of the dominant blue-green algae from a freshwater lake inhibited the growth of diatoms isolated from the same lake. Lake waters, collected during blue-green algal blooms, also inhibited diatom growth. In situ observations over a 5-year period indicate that diatom bloom populations vary inversely with the levels of the preceding blue-green al...

Allelopathy is one of the alternatives used for integrated weed management (IWM), in order to minimize use synthetic herbicides. defined as effect produced by a chemical released donor plant on development another competitive recipient plant.

Connolly, 1990). Crown rust is the most serious ryegrass fungal pathogen in these areas (Eagling and Clark, 1993), Perennial ryegrass (Lolium perenne L.) and white clover (Trifowith epidemics regularly occurring between spring and lium repens L.) are important pasture components in the higher rainfall areas of southeastern Australia. Crown rust (Puccinia coronata autumn. A preliminary study dem...

Presently, chemical control is the most used method for plant protection. However, it not an approach that environmentally sustainable. Alternative IPM methods include biological such as Allelopathy can be a good alternative in protection.Allelopathy defined direct or indirect interaction, whereby allelochemicals released by one organism influence physiological processes of other neighboring or...
