Eichhornia crassipes (Mart.) Solms is a free-floating aquatic macrophyte growing normally to a height of 0.5 m to 1 m. This weed causes, substantial economic and ecological harm, warranting its removal, lest the impacts of the weed should become permanent. From an ecological perspective, the most effective, management approach is to make use of the weed for various purposes. The present study o...

crops that better tolerate weed competition or preempt resources from weeds may reduce dependence on herbicides and benefit an integrated weed management program. a field trail was conducted to determine the morphophysiological characteristics affecting tolerance and weed suppressive ability of some winter wheat cultivars in competition with rocket. the experimental treatments consisted of eigh...

C ourtier-Orgogozo et al [1] argue that public debate and better governance are needed to properly control the use of gene editing for controlling pests in agriculture. They are correct in their assessment that this “could lead to multiple and uncoordinated releases of gene drives into the wild, which is likely to cause unpredictable ecological disturbances with farreaching consequences”. Howev...

BACKGROUND In this work, we aimed to gain insights into the contribution of soil bacteria to carbon sequestration in Mediterranean habitats. In particular, we aimed to use bacterial laccase-encoding genes as molecular markers for soil organic C cycling. Using rainfed olive farming as an experimental model, we determined the stability and accumulation levels of humic substances and applied these...

abstract increased knowledge of russian knapweed biology would facilitate development of an optimum control program. to examine germination characteristic of this weed, several experiments were conducted in weed research department, plant pest and diseases research institute of tehran during 2003. first experiment was a factorial with 3 replications to break seed dormancy of this weed. first fa...
