Inorganic copper is used as a broad-spectrum fungicide and bacteriocide on a variety of agricultural crops. After application, the copper residue typically accumulates in the upper 15 cm of soil. Data from the California Pesticide Use Reports were used to estimate the augmentation of copper in the soil that resulted from pesticide applications for the six years from 1993 to 1998 on 12 crops tha...

Short-term effects of ozone (O(3)) on phyllosphere fungi were studied by examining fungal populations from leaves of giant sequoia (Sequoiadendron giganteum (Lindl.) Buchholz) and California black oak (Quercus kelloggii Newb.). Chronic effects of both O(3) and sulfur dioxide (SO(2)) were studied by isolating fungi from leaves of mature Valencia orange (Citrus sinensis L.) trees. In this chronic...

This study sought to characterize the effects of some citrus fruit juices (shaddock [Citrus maxima], grapefruit [Citrus paradisii], lemon [Citrus limoni], orange [Citrus sinensis], and tangerine [Citrus reticulata]) on acetylcholinesterase activity in vitro. The total phenolic content, radical scavenging abilities, and inhibition of Fe(2+)-induced malondialdehyde (MDA) production in rats brain ...

Continued application of synthetic insecticides arise development of resistance and pollution of the environment. Laboratory experiments were conducted to test the efficacy of products of orange (Citrus sinensis) peels in the control of the stored products beetle Zabrotes subfasciatus (L) in stored haricot beans (latin name). Different levels of the extracts and essential oil of Citrus sinensis...

Calcareous and alkaline nature of soil hinders smooth up take micronutrient from soil. Hence, the impact foliar feeding micronutrients (Zn, Fe, B, Cu) in different combinations on growth, yield quality sweet orange cv. Mosambi a non-conventional citrus growing area was evaluated. Results revealed that treatment combination Zn @ 0.5% + Fe 0.2% B 0.3% Cu 0.1% (T9) followed by (T6) (T7) most effec...
