The emergence of use of biological herbicides
Serious attention to hazardous chemical pesticides began with publication of the book “Silent Spring” by Rachel Carson in 1962. Scientists believe that agriculture had the greatest impact on the environment. The most reliable evidence comes from application of million tons of chemical fertilizers and pesticides with short or long adverse effects on ecosystem. Therefore, it is essential to imple...
متن کاملSeedling Emergence and Biomass Growth of Oleaginous and Other Tropical Species in Oil Contaminated Soil
Germination rate in contaminated soils cannot be used as the sole indicator to select suitable species for phytoremediation trials, since it does not predict the plant development after germination. As a result, most screening tests for selection of specie with phytoremediation potential to treat contaminated soils include germination rate and biomass production. These screenings take several m...
متن کاملResponse of Poaceous Weeds in Wheat to Post-Emergence Herbicides
Poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. Herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. The current study was undertaken...
متن کاملThe Efficiency of Integrated Pre-Emergence and Post-Emergence Herbicides in Nutrient Uptake by Wheat and Nutrient Depletion by Weeds in Sesame-Wheat Cropping System in Khuzestan
In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...
متن کاملInfluence of Edge Exposure on Tree Seedling Species Recruitment in Tropical Rain Forest Fragments’
Edge creation has a pronounced influence on the understory vegetation, but the effects of edges on seedling species recruitment are still poorly understood. In Central Arnazonia, 9-1 9 years after fragmentation, we recorded species richness and net seedling recruitment rate in 1 ha blocks exposed to none, one, or multiple edges within forest fragments. One-hectare blocks were located in the cen...
