There has been a heavy reliance on fungicides to control disease but some of the most effective fungicides are now being withdrawn through EU regulations.
So there is a need to develop oilseed crop varieties with greater inbuilt resistance to the disease.
Plots sprayed with fungicide soon become dominated by a few species at the expense of many others leading to a marked drop in diversity.'
Researchers sprayed plots with water insecticide or fungicide every week for 17 months. They found that the fungicide Amistarâ dealt a significant blow to diversity reducing the effective number of species by 16%.
%While the insecticide did change the composition of surviving species it did not have an overall impact on diversity.'
'We expected that removal of both fungi and insects would have an effect on the tree species'said Professor Rob Freckleton of Sheffield University who co-led the study.'
No magic bullet for coffee rust eradicationspraying fungicide to kill coffee rust disease which has ravaged Latin american plantations
but spraying fungicides to kill it may inadvertently destroy natural fungal enemies of coffee rust that help to keep it in check.
The techniques of so-called modernization (e g. cutting shade applying fungicides) may gradually eliminate what has been effectively autonomous biological control of coffee rust.
and applying fungicide is one of the main control methods promoted in the affected countries.
But generalized fungicides can also kill the white halo fungus which is known to attack coffee rust.
#Exposure to pesticides results in smaller worker beesexposure to a widely used pesticide causes worker bumblebees to grow less
The research published today in the Journal of Applied Ecology reveals that prolonged exposure to a pyrethroid pesticide
The researchers Gemma Baron Dr Nigel Raine and Professor Mark Brown from the School of Biological sciences at Royal Holloway worked with colonies of bumblebees in their laboratory and exposed half of them to the pesticide.
Our result revealing that this pesticide causes bees to hatch out at a smaller size is of concern as the size of workers produced in the field is likely to be a key component of colony success with smaller bees being less efficient at collecting nectar
The study is the first to examine the impact of pyrethroid pesticides across the entire lifecycle of bumblebees.
Given the current EU moratorium on the use of three neonicotinoid pesticides the use of other classes of pesticide including pyrethroids is likely to increase.
Our work provides a significant step forward in understanding the detrimental impact of pesticides other than neonicotinoids on wild bees.

It's a great bonus for us that this also causes them to attract pollutants making them a cheap and natural way of tracking pesticides and air quality around the world.'
when ranchers put pesticides on the carcasses of cows and other animals killed by lions or hyenas.
He expects to find a wide variety of pollutants in the samples including mercury pesticides flame retardants PCBS and other organic pollutants.
They supplemented insecticide sprays with (Z)- 9-hexadecenal a pheromone compound attractive to ants and were able to divert Argentine ants from their trails and nest entrances.
Lured by the pheromone the ants were exposed eventually to the insecticide residue and killed. Study results appeared Dec 23 2013 in the online fast track edition of the Journal of Economic Entomology.
Our experiments with fipronil and bifenthrin sprays indicate that the overall kill of these insecticides on Argentine ant colonies is improved substantially--by 57 to 142 percent--by incorporating (Z)- 9-hexadecenal in the sprays said Dong-Hwan Choe an assistant professor of entomology
-and-kill approach once it is implemented successfully in practical pest management programs could potentially provide maximum control efficacy with reduced amount of insecticides applied in the environment.
Given the amount of insecticides applied today to urban settings for Argentine ant control and the impact of these insecticides on urban waterways it is critical to develop alternative integrated pest management strategies
in order to decrease the overall amounts of insecticides applied and found in urban waterways while still providing effective control of the target ant species Choe said.
He explained that other studies have explored the possibility of using the synthetic pheromone (Z)- 9-hexadecenal for Argentine management program.
What makes our study unique is that we combine the insecticide sprays and low-dose pheromone to attract ants Choe said.
if the pheromone is mixed with the insecticide formulation and held in long-term storage. Some of these questions could be addressed with assistance from industry collaborators.

Turning tobacco plants into factories for cleaner pesticides For more eco-friendly pest control, scientists have modified genetically tobacco plants,
As pesticides, pheromones are nontoxic and biodegradable, and small amounts (just tens of grams per hectare) are needed to be effective--making them an environmentally-friendly alternative to traditional pesticides for trapping bugs.
But the commercial production of large amounts of synthetic pheromones requires the use of harmful chemicals (such as neurotoxins hexane

The world spends more than $14 billion on herbicide a year. The Environmental protection agency is examining the human and environmental health risks
In the meantime, Monsanto and its corporate agricultural rivals are scrambling to roll out different herbicides and new herbicide-tolerant crops that they hope will halt the advance of weed resistance and silence critics.

The crux of these awards is that they recognize innovations in sustainable agricultural that encourage the rise of so-called sustainable agriculture--which encourages farming according to methods that don t introduce chemical pesticides
The environment has eliminated so far the need for pesticides he says. The company envisions supermarkets growing produce under the store

and East Malling Research have come up with a novel way of using bumble bees to deliver minute quantities of bio-fungicide to strawberry flowers.
As the bees move through the dispenser a minute quantity of a powdered formulation of the bio-fungicide containing Gliocladium catenulatum adheres to their bodies and legs.
allowing a very precise application of this bio-fungicide throughout flowering. The bio-fungicide, which is itself a fungus,
competes for living space with the grey mould on the flower parts, preventing the latent flower infection
During the last two years of field trials this harmless bee-delivered control system was demonstrated to be a practical alternative to fungicide applications
and regularly achieved levels of grey mould control equivalent to areas treated with fungicides while significantly decreasing any residue left on the fruit itself.
Data from this Hortlink project and ongoing trials in Finland and Belgium, where this technique is already being adopted will be used to support an application for pesticide registration of this fungicide dispersed by bees in the UK.
