The main goal of this study was to determine the levels of knowledge of the farmers on the effect of pesticides on environment in Dawadmi Province, Saudi Arabia. This is achieved through realizing some secondary objectives such as identification of the farmers' socioeconomic characteristics and its relation to some of the study variables, their attitude towards the negative effects of pesticide...

BACKGROUND Approximately 75% of pesticide usage in the United States occurs in agriculture. As such, agricultural workers are at greater risk of pesticide exposure than non-agricultural workers. However, the magnitude, characteristics and trend of acute pesticide poisoning among agricultural workers are unknown. METHODS We identified acute pesticide poisoning cases in agricultural workers bet...

Allelopathic potential of aqueous extracts of lantana (Lantana camara L.) leaf on germination and growth of three agricultural crops: Maize, Finger millet and Tef, commonly cultivated in Ethiopia were studied under laboratory condition. The aqueous extracts were assayed at 5, 10, 25, 50 and 75% and their allelopathic effects were compared with distilled water (control). All the aqueous extracts...

An Expert System is a system that employs human knowledge captured in a computer to solve problems that ordinarily require human expertise. In agriculture, expert systems unite the accumulated expertise of individual disciplines, such as plant pathology, entomology, horticulture and agricultural meteorology and Animal Sciences; into a framework that best addresses the specific, on-site needs of...

Ultraviolet-B (UV-B) radiation and elevated tropospheric ozone may cause reductions in the productivity and quality of important agricultural crops. However, research regarding their interactive effect is still scarce, especially on the belowground processes. Using the open top chambers experimental setup, we monitored the response of soil nematodes to the elevated O3 and UV-B radiation individ...

Climate change is one of the most serious problems facing the world today. The recent Intergovernmental Panel on Climate Change reports confirmed that climate change will have a significant impact on global surface temperature. The projections of IPCC are that the rise of the mean temperature will be as high as 6.4oC by 2100, while the concentration of CO2 will be 1.3 times higher than it was 2...

It has been 10 years since the last review on apomixis, or asexual seed formation, in this journal (Koltunow, 1993). In that article, emphasis was given to the commonalties known among apomictic processes relative to the events of sexual reproduction. The inheritance of apomixis had been established in some species, and molecular mapping studies had been initiated. The molecular relationships b...

Phytoplasmas are insect-transmitted bacterial plant pathogens that cause considerable damage to a diverse range of agricultural crops globally. Symptoms induced in infected plants suggest that these phytopathogens may modulate developmental processes within the plant host. We report herein that Aster Yellows phytoplasma strain Witches' Broom (AY-WB) readily infects the model plant Arabidopsis (...
