Summary / Description

Summary / Description	This is a dissertation-like document apparently produced as a final report for a postdoctoral fellowship. As part of the study, the author evaluated plants in Pakistan and Japan that have allelopathic effects, i.e. natural herbicidal effects. Two of the plants studied that appear to have high value are in the family Cupressaceae claimed in this patent.

Excerpt

Excerpt

"The importance of allelopathy in nature and in agroecosystem has attracted researcher's attention with the main goal of using the phenomenon in biological control of weeds. Presently, active involvement of scientists from different disciplines made allelopathy a multidisciplinary subject, and transformed the research from basic to applied, enabling use of allelopathy in agriculture and forestry. Screening accessions of allelopathic crops and natural vegetation for their ability to reduce weeds is the basic approach for utilizing the phenomenon (Kebede, 1994). The recognized importance of allelopathy in agricultural practices has been increased with the main objectives of using this phenomenon in biological control of weeds (Rice, 1984). One approach to utilize this phenomenon is suggested to screen accessions of allelopathic crops for their ability to reduce weeds, and a few crops have been evaluated in this aspect (Leather, 1982)."
