Feedstocks for industrial applications ranging from polymers to lubricants are largely derived from petroleum, a non-renewable resource. Vegetable oils with fatty acid structures and storage forms tailored for specific industrial uses offer renewable and potentially sustainable sources of petrochemical-type functionalities. A wide array of industrial vegetable oils can be generated through biot...
With the discovery of the larval parasitoid, Cotesia plutellae Kurdjumov, and the successful introduction and establishment of two other exotic parasitoid species, viz. Diadegma semiclausum Hellen and Diadromus (Thyraeella) collaris Gravenhorst in the Cameron Highlands, biological control was given greater emphasis in the development of IPM for diamondback moth, Plutella xylostella (L.), in Mal...
Industrialized small-scale pig farming has been rapidly developed in developing regions such as China and Southeast Asia, but the environmental problems accompanying pig farming have not been fully recognized. This study investigated 168 small-scale pig farms and 29 example pig farms in Yujiang County of China to examine current and potential impacts of pig wastes on soil, water and crop qualit...
Global constraints on fresh water supplies and the need to dispose of agricultural, municipal, and industrial waste waters have intensified interest in water reuse options. In many instances, the value of the water is decreased solely because of its higher salt concentration. Although quantitative information on crop salt tolerance exists for over 130 crop species, there are many vegetables whi...
Solanum melongena Linn. (brinjal) is the most common, popular and principal vegetable crop grown in many geographical parts in India. This staple vegetable crop is extensively damaged by the insects and farmers use large quantities of chemical insecticides, Carbaryl being one of them. The present study was undertaken to evaluate the persistence of Carbaryl on brinjal (fruit) and soil in an agri...
Relative to USDA dietary guidelines there is a 30% deficit in vegetable production and a 100% deficit in fruit production in the US. The western US, especially California, dominates current production of both fresh and processed fruits and vegetables. Constraints in land and water resources in California suggest that some shifts in production could occur in the future if production is matched t...
Crucifers comprise a major group of vegetable crops in the Changjiang River Valley, China. The control of insect pests on crucifer vegetable crops has largely relied on the heavy use of chemical insecticides in the last 30 years, resulting in serious consequences of insecticide resistance, increased costs of control and insecticide residues hazardous to human health. A group of Chinese and Aust...
The spatial distribution of crop and non-crop habitats over segmented agricultural landscapes could be used as a means to reduce insect pest populations. Seven land cover categories such as wheat, rapeseed, vegetable, water, built-up, paved road, and unsurfaced road were extracted from GeoEye satellite images dating from late May to late June of 2010. Three diversity metrics and three evenness ...
