Weed management is the major biological constraint in paddy (Oryza sativa L.) producing areas. Predominantly, barnyard grass (Echinochloa crus-galli) a rice-mimicking weed that causes 57% of yield loss rice production. Conventionally, herbicides are site-specific inhibitors often used to suppress E. crus-galli growth. Acetyl-CoA carboxylase (ACCase) an important target for developing novel with...
A series of new N,N'-diacylhydrazine derivatives were designed and synthesized. Their structures were verified by 1H-NMR, MS and elemental analysis. The herbicidal activities and plant growth regulating activity of these N,N'-diacylhydrazines were evaluated. The herbicidal activity results showed that most of these N,N'-diacyl-hydrazines showed excellent in vivo activities against Echinochloa c...
The productivity of paddy rice in Malaysia has improved as the technology advances. However, several concerns need to be considered to maintain the productivity. The growth of paddy weeds in the fields is one of the concerns that need to be taken care of as it resulted to the decrease of the paddy yield. This paper presents an integrated method for classifying paddy weeds through the shape of t...
