Abstract:
... An easy to synthesize luminescent, amphiphilic probe has been designed for the first time in optical sensing of a biopesticide, Helicoverpa armigera nuclear polyhedrosis virus (HaNPV). The compound showed formation of a pH-sensitive, thermoreversible nanoaggregate in the aqueous medium. The addition of HaNPV resulted in the rapid change in emission color from blue to cyan at pH 7.4. Till date, no ...

Abstract:
... Point-of-care technology is a term used to describe any treatment given at the “site-of-need”. The span of point-of-care has broadened, growing from its current dominant usage in clinical settings to encompass many sectors, such as water and food testing. This review focuses on applications of point-of-care/use technology in phytodiagnostics, a field which requires accurate diagnostic systems with ...

Abstract:
... Crop loss to foraging elephants is one of the most significant causes of conflict between people and elephants in areas where wild elephants share resources with people. Effective solutions to reduce the effects of human–elephant conflict on local livelihoods are thus essential to foster coexistence between elephants and people. We assessed the effectiveness of chilli-briquettes (bricks made of dr ...

Abstract:
... Crop loss due to plant pathogens has provoked renewed interest in bacteriophages as a feasible biocontrol strategy of plant diseases. Phage cocktails in particular present a viable option for broadening the phage host range, limiting the emergence of bacterial resistance while maintaining the lytic activity of the phages. It is therefore important that the design used to formulate a phage cocktail ...

Abstract:
... Crop type information at the field level is vital for many types of research and applications. The United States Department of Agriculture (USDA) provides information on crop types for US cropland as a Cropland Data Layer (CDL). However, CDL is only available at the end of the year after the crop growing season. Therefore, CDL is unable to support in-season research and decision-making regarding c ...

Abstract:
... Garden cress (Lepidium sativum L., Brassicaceae) is one of the most popular leafy vegetables which is widely used, and has also various medicinal properties and industrial usage. Small and very delicate leaves of this short period and fast growing species cause lots of crop losses along production to consumption; so it was supposed that increase in thickness and size of the leaves via induction of ...

Abstract:
... Resistance to maize rough dwarf disease (MRDD), a major cause of crop losses, depends on external conditions such as the virus transmission period and the rate of viruliferous small brown planthoppers, Laodelphax striatellus. The precise identification of MRDD contributes to the utilization of resistant germplasm and the cloning of resistant genes. In this study, eight maize varieties were artific ...
