Rice allelopathy in weed management – An integrated approach

True integrated weed management

Using the simplest of definitions, integrated weed management has been described as “putting components [of weed control] together, not taking them apart.” Yet, weed science has stopped at the “field edge” in assembling the components into a truly integrated approach. What is keeping weed scientists from developing real integrated weed control regardless of space and time? The answer to this qu...

Rice Allelopathy and Momilactone

Rice has been extensively studied with respect to its allelopathy as part of a strategy for sustainable weed management options. All available information indicates that rice plants possibly release unknown allelochemicals into the neighbouring environments. A large number of compounds, such as phenolic acids, fatty acids, indoles and terpenes, were identified in rice root exudates and decompos...

Upland Rice and Allelopathy

Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chem...

Allelopathy an Environmentally Friendly Method for Weed Control

Biological weed management is a system that incorporates the use of diverse biological organisms and biologically-based approaches including allelopathy, crop competition, and other cultural practices to significantly reduce weed densities in a manner that is similar to use of chemical herbicides alone. Interest in developing effective biological weed management systems continues to increase be...
