Beekeepers sue EPA over failing to stop harmful pesticides | The Raw Story

Beekeepers sue EPA over failing to stop harmful pesticides | The Raw Story | Natural Pest Control | Scoop.it

Beekeepers, conservation and food campaigners accuse Environmental Protection Agency of failing to protect the insects

 

The lawsuit accuses the Environmental Protection Agency (EPA) of failing to protect the insects – which pollinate three-quarters of all food crops – from nerve agents that it says should be suspended from use. Neonicotinoids, the world’s most widely used insecticides, are also facing the prospect of suspension in the European Union, after the health commissioner pledged to press on with the proposed ban despite opposition from the UK and Germany.

 

The EPA declined to comment on the lawsuit, but said in a statement: “We are working aggressively to protect bees and other pollinators from pesticide risks through regulatory, voluntary and research programmes. Specifically, the EPA is accelerating the schedule for registration review of the neonicotinoid pesticides because of uncertainties about them and their potential effects on bees.” However, even the accelerated review will not be completed before 2018.

Researchers still seeking to understand Colony Collapse Disorder - Mount Airy News

Researchers still seeking to understand Colony Collapse Disorder - Mount Airy News | Natural Pest Control | Scoop.it

Mount Airy News (David Broyles)
Researchers still seeking to understand Colony Collapse Disorder. Much prevailing wisdom on the subject has first centered on studying the interaction of elements to the disorder's pathology, parasites and pathogens.

Knapco's insight:

Tarpy indicated the demise of the disorder by merely abolishing one group of pesticides known as neonicotinoids touted in many print articles is premature. He said data available now seems to lean towards CCD being the product of many different factors.

“It (CCD) is still a serious threat,” said Tarpy. “The problem with the single pesticide solution is there have been no reproducible results we can tie to a pesticide. As far as strictly considering CCD studies recently, they (the neonicotinoid family of pesticides) do not seem to be directly involved.”

Chestnut Extracts in Managing Soilborne Plant Pathogens

Hao JJ et al. (2012) studied antimicrobial activity of chestnut extracts for potential use in managing plant pathogens.

Chestnut extracts were studied for antimicrobial activity against selected microorganisms, including plant pathogens. Most test microorganisms were inhibited by the extracts at different effective concentrations for 50% growth inhibition (EC50). Pseudomonas fluorescens was the most sensitive, Phytophthora cambivora was one of the least inhibited, and Cryphonectria parasitica was not inhibited.

Extracts of the Japanese × European chestnut (Castanea crenata × C. sativa) ‘Colossal’ showed a greater inhibition than those of wild trees of the Chinese species (C. mollissima).

Pellicle and shell tissue reduced radish scab disease caused by Streptomyces scabies in the greenhouse.

EPA Takes Action Against Companies That Sell And Import Illegal Pesticides

EPA Takes Action Against Companies That Sell And Import Illegal Pesticides | Natural Pest Control | Scoop.it

In many situations, there are non-chemical methods that will effectively control pests. The EPA recommends the use of alternative methods as part of an overall pest management strategy. The EPA recommends the use of alternative methods as part of an overall pest management strategy.

Knapco's insight:

“When stores sell illegal pesticides, the health and safety of people are put at risk,” said EPA Regional Administrator Judith A. Enck.

Before a pesticide product is registered, the producer of the product must provide data from tests conducted according to EPA guidelines to ensure that the product will not be harmful to people’s health. The EPA examines the ingredients and the way in which the product will be used, and assesses a wide variety of potential human health and environmental effects associated with its use. Distributors and retailers are responsible for ensuring that all pesticides distributed and sold fully comply with the law. During 2011 and 2012, EPA Region 2 conducted over 250 inspections of retail outlets, and pesticide distributors and importers in New Jersey and New York, removing over 20,000 units of illegal pesticides in the process.

Pest Control Methods That Don't Involve Chemicals

Pest Control Methods That Don't Involve Chemicals | Natural Pest Control | Scoop.it

Can Non Chemical Strategies for Managing Pests like Exclusion or Clean Sanitation be used also in plant production?

The usefulness of non-chemical approaches is dependent upon the understanding of pest ecology, biology, and behavior. However, this understanding isn't really required when using the synthetic pesticides.

Beneficial organisms - toxicity, ecological toxicity and regulatory information

Beneficial organisms - toxicity, ecological toxicity and regulatory information | Natural Pest Control | Scoop.it

Several Trichogramma wasps species are known to be parasiotids of buterfly family (Lepidoptera). Trichogramma species are the most widely-studied agents of biological control in the field of entomology. But it is less known, that they can be also registered as insecticides.


In PAN Pesticides Database Trichogramma pinto and T. evanescens could be found among chemicals: identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information is given also for these beneficial organisms like for any other pesticide. 

Data on 6,500 pesticides, insecticides and herbicides including toxicity, water pollution, ecological toxicity, uses and regulatory status is provided in Pesticides Action Network database.
