Biological control agents (BCAs), which use living organisms or their products, are a necessity for organic kiwifruit growers who want non-chemical control options, and offer alternatives for managing plant pathogens that are resistant or tolerant to chemical pesticides. (plantandfood.co.nz)
Approval for invertebrate pest species or pathogens as candidates for biological control should be sought through the Plant Health Committee (PHC). (agriculture.gov.au)
Mixed model equations (MME) and best linear unbiased predictors (BLUPs) have been used to determine the probable host-range of plant pathogens proposed for biological control of Russian thistle. (b3.net.nz)
One way to manage invading non-native plants in Florida's aquatic systems is to use biological control agents such as insects, fish and pathogens. (ufl.edu)
The project will also include the molecular characterization of the most virulent, newly isolated plant pathogens and the experiments in planta, in order to confirm the capacity of tested strains for use in biological control. (ac.rs)
A procedure to assess pathogenicity (LC50) and its standardization is crucial for research into the use of pathogens as biocontrol agents. (usda.gov)
Many other biological agents, in contrast, are harmless (apathogenic) or only pose a hazard to vulnerable persons (opportunistic pathogens). (baua.de)
This study constitutes an initial screening of endophytes as biological control agents against diverse fungal pathogens and forms a basis for the discovery of novel strains that can be further developed and integrated into disease management systems for diverse fungal pathogens. (ashs.org)
Isolates B. vallismortis (PS), B. amyloliquefaciens (Psl), B. subtilis (Prt), and B. thuringiensis (Y IMC8) exhibited the best performance as potential biological control agents paving the way for larger-scale in vivo studies and characterization of their interactions with fungal pathogens.

This project builds on the initial findings of the researcher's team on identification of a new biological control agent (BCA), a new species of fungus native to Saskatchewan developed into a biopesticide to fight mycotoxigenic Fusarium- FHB pathogens. (saskwheat.ca)

Biological control of exotic invasive plants using exotic insects is practiced under the assumption that biological control agents are safe if they do not directly attack non-target species. (usda.gov)
To minimize indirect risks to non-target species, biological control agents must suppress pest populations enough to reduce their own numbers. (usda.gov)
Other thrips species have also become more difficult to control or occur more frequently on greenhouse crops in different areas of the country. (usda.gov)
Release of a biocontrol agent in New Zealand is typically preceded by non-target testing of native or valued species. (springer.com)

As the nematode produced galls on 13 native Solanum species and 13 of 15 S. melongena (eggplant) cultivars tested, the lack of adequate specificity of D. phyllobius makes this nematode an unsuitable agent for release in Australia. (weedinfo.com.au)
However, the selectivity of the monitoring method must be at the strain level, because many biological control agents belong to species that are common inhabitants of plants ( 18 ). (asm.org)
For the biological control of weeds, the weed species must be submitted to the Invasive Plants and Animals Committee (IPAC) for approval as a target. (agriculture.gov.au)
The proposer usually searches for potential biological control agents in the natural range of the target species. (agriculture.gov.au)
Candidate biological control agents presently under evaluation for release on L. camara in South Africa accept closely related native plant species. (b3.net.nz)
The work focuses on evaluating disease severity on related plant species although the author describes how MME can be used with any biological weed control agent or target as long as the evaluation criterion is quantitative and variances and molecular genetic relationships among test species can be obtained.
