Pest management techniques have evolved over the past 50 years. Inorganic chemical pesticides were replaced by synthetic organic chemicals, and now biopesticides constitute a significant part of pest management technology. Requirements for the regulatory approval of pesticides changed dramatically in 1996 with the passage of the Food Quality Protection Act (FQPA). The FQPA directs the U.S. Envi...
In the track of new biopesticides, four genes namely cytA, cytB, cytC and cytD encoding proteins homologous to Bacillus thuringiensis (Bt) Cyt toxins have been identified in the plant pathogenic bacteria Dickeya dadantii genome. Here we show that three Cyt-like δ-endotoxins from D. dadantii (CytA, CytB and CytC) are toxic to the pathogen of the pea aphid Acyrthosiphon pisum in terms of both mor...
Organisms such as bacteria, fungi, viruses, and nematodes cause yield quality loss in agricultural production. Especially the control of fungal pathogens is challenging. The fact that chemical pesticides used these are not environmentally friendly, increases importance alternative methods use biopesticides. Biopesticides relatively harmful to human health environment generally secondary metabol...
