Inoculants or biofertilizers aiming to partially fully replace chemical fertilizers are becoming increasingly important in agriculture, as there is a global perception of the need increase sustainability. In this review, we discuss some results inoculation variety crops with rhizobia and other plant growth-promoting bacteria (PGPB). Important improvements quality inoculants on release new strai...

A field experiment was conducted to compare the effectiveness of microbial control agents and chemical pesticides when used on field tomatoes. Treatments included all combinations of chemical, biological or no control of either diseases or insect pests. Irrigation problems prevented uniform development of the crop in the field, and caused one experimental block to have significantly lower yield...

RNA interference (RNAi)-based pesticides are pest control agents that use RNAi mechanisms as the basis of their action. They regarded environmentally friendly and a promising alternative to conventional chemical pesticides. The effective substance in RNAi-based is double-stranded (dsRNA) designed match nucleotide sequence target essential gene concern. When taken up by pest, this exerts an effe...

We report herein a whole cell-based amperometric biosensor for highly selective, highly sensitive, direct, single-step, rapid, and cost-effective determination of organophosphate pesticides with a p-nitrophenyl substituent. The biosensor was comprised of a p-nitrophenol degrader, Pseudomonas putida JS444, genetically engineered to express organophosphorus hydrolase (OPH) on the cell surface imm...

Microbes are ubiquitous, survive in all sorts of environments and have a profound influence on the earth. In the present day plant protection scenario, development of resistance to chemical pesticides is the major hurdle in insect pest management. In recent years, several microbes with potential insecticidal properties have come to light. Viruses, bacteria, fungi and protozoa that are known to ...

The development of biofilms on modified natural zeolites was investigated with purpose to obtain biocomposites biodegradation activity towards pesticides MCPA (2-methyl-4-chlorophenoxyacetic acid) and glyphosate (N-(phosphonomethyl)glycine) for potential application in bioaugmentation polluted agricultural soils. Microbial communities were selected from pesticide-contaminated soil/water samples...

Abstract The phenylurea herbicides are an important group of pesticides used extensively for pre- or post-emergence weed control in cotton, fruit and cereal crops worldwide. The detection of phenylurea herbicides and their metabolites in surface and ground waters has raised the awareness of the important role played by agricultural soils in determining water quality. The degradation of phenylur...

Microbial pathogens are thought to have a profound impact on insect populations. Honey bees are suffering from elevated colony losses in the northern hemisphere possibly because of a variety of emergent microbial pathogens, with which pesticides may interact to exacerbate their impacts. To reveal such potential interactions, we administered at sublethal and field realistic doses one neonicotino...

Soil microbial activity is adversely affected by pollutants such as heavy metals, antibiotics and pesticides. Organic amendments including sewage sludge, municipal compost and vermicompost are recently used to improve soil structure and fertility. But, these materials contain heavy metals including Pb, Cd, Zn, Ni and Cu that are toxic to soil microorganisms and may lead to occurrence of more to...

The global food supply has been facing increasing challenges during the first decades of the 21st century. Disease in plants is an important constraint to worldwide crop production, accounting for 20-40% of its annual harvest loss. Although the use of resistant varieties, good water management and agronomic practices are valid management tools in counteracting plant diseases, there are still ma...
