More than 100 scientists signed a letter to the British prime minister, Tony Blair, last month complaining about the way the debate on GM crops was handled. The topic has been hitting the headlines in the UK and Europe as researchers, protesters, industry and governments have been battling to find a way forward. But many researchers now believe that their corner has been unfairly treated. Publi...

The state of Morelos is the main producer figs in Mexican Republic, contributing 50% national production. Despite fact that official regulations Mexico only allow use some pesticides on figs, it common to find residues prohibited substances. This work aims assess occurrence pesticide fig cultivation from 15 different parcels located order determine their degree dissipation and resultant health ...

The Environmental Hazards Assessment Program of the California Department of Food and Agriculture conducted a well survey in Tulare County to determine the presence of the herbicides simazine, atrazine, prometon, bromacil and diuron in well water. These herbicides were chosen because of their use on crops grown in Tulare County and on rights-of-way throughout the state. Twelve sampling areas we...

Generalist predatory mites belonging to the Phytoseiidae play a major role in keeping phytophagous mites below economic threshold levels in European apple orchards and vineyards. Apart from their primary prey, these phytoseiids can exploit a range of other foods, among which pollen and plant pathogenic fungi are very important. The ability of generalist predatory mites to feed on alternative fo...

The objective was to conduct a dietary risk assessment of pesticides registered in Brazil up to 14 January 2004. The theoretical maximum daily intake (TMDI) was calculated for 275 compounds using the Brazilian maximum residue limits (MRL) and food consumption. The chronic dietary risk assessment was conducted by comparing the TMDI with the Brazilian acceptable daily intake (ADI) or, when not av...

Cucumber is one of the main vegetables in Iranian food basket. A wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. Analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. This study was aime...

Organic agriculture is a production system that relies on prevention, ecological processes, biodiversity, mechanical and natural cycles to control pests maintain productivity. Pesticide use generally limited or absent in organic agroecosystems, contrast with non-organic (conventional) systems primarily rely pesticides for crop protection. Significant differences pesticide between the two marked...

A review of the literature shows that the environmental risks and benefits of genetically modified crops have varying degrees of certainty. For example, field studies have documented growing resistance to highly used pesticides. However, the risks of gene flow and deleterious effects on non-target organisms have not been evaluated at large field scales. Similarly, reduced pesticide use and toxi...

Aero-Pipeline Spraying System is a special ultra-working-width precision pesticide sprayer, which can broaden working scope, improve working efficiency, precisely transfer feed liquid to farm field that need to be sprayed, spray pesticides to crops in a very close range, and then improve working precision and reduce the losses of liquid materials such as pesticides. During the ultra-working-wid...
