Effects of Bacillus velezensis strain BAC03 in promoting plant growth
In this study, BAC03 was tested for potential growth promotion on nine selected types of plants, including beet, carrot, cucumber, pepper, potato, radish, squash, tomato, and turnip, at the concentration of 105 colony forming unit cm-3 potting mix under greenhouse conditions. Results showed that BAC03 increased the growth of some tested plants at various levels in different plant parts. Application of BAC03 at 10 days after planting was associated in radish with the highest biomass gain compared to applications at other stages.

Publication date: Available online 22 January 2016 Source:Biological Control Author(s): Olfa Kilani-Feki, Saoussen Ben Khedher, Mouna Dammak, Amel Kamoun, Hayfa Jabnoun-Khiareddine, Majda Daami-Remadi, Slim Tounsi The aim of the present study is to optimize the production of antifungal metabolites produced by Bacillus subtilis V26 and to evaluate its efficiency in suppression Botrytis cinerea, the main cause of tomato fruit rot disease. Different media were tested for antifungal metabolite production, including chitosanase, by V26. Both of antifungal and chitosanase activities were highly produced in M13medium, wh...

Compost from forest cleaning green waste and Trichoderma asperellum strain T34 reduced incidence of Fusarium circinatum in Pinus radiata seedlings
In conclusion, one gorse compost decreased the incidence of F. circinatum disease when used as a growth medium for P. radiata seedlings. T. asperellum strain T34 further reduced the incidence of disease and improved the health of pine seedlings grown in moderately non-suppressive composts. (Source: Biological Control)

Conidial production, persistence and pathogenicity of hydromulch formulations of Metarhizium brunneum F52 microsclerotia under forest conditions
Publication date: Available online 9 January 2016 Source:Biological Control Author(s): Tarryn A. Goble, Sana Gardescu, Joanna J. Fisher, Mark A. Jackson, Ann E. Hajek Microsclerotia granules of Metarhizium brunneum Petch strain F52 (Hypocreales: Clavicipitaceae) in a hydromulch formulation (water, wheat straw, and tackifier) were sprayed onto bark or wood samples, which were subsequently exposed on tree trunks for 4–30 d, during two spray trials in 2013 and six spray trials in 2014. Microsclerotial granules in this formulation continued to produce many infective conidia over a 30 d period in a forest. Greater ...

Beauveria bassiana and Metarhizium anisopliae endophytically colonize cassava roots following soil drench inoculation
Publication date: Available online 9 January 2016 Source:Biological Control Author(s): Melinda Greenfield, María I. Gómez-Jiménez, Viviana Ortiz, Fernando E. Vega, Matthew Kramer, Soroush Parsa We investigated the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae to determine if endophytic colonization could be achieved in cassava. An inoculation method based on drenching the soil around cassava stem cuttings using conidial suspensions resulted in endophytic colonization of cassava roots by both entomopathogens, though neither was found in the leaves or stems of the treated c...

Heat shock improves stress tolerance and biocontrol performance of Rhodotorula mucilaginosa
Publication date: Available online 11 January 2016 Source:Biological Control Author(s): Zhe Cheng, Mengshan Chi, Guangkun Li, Huizhen Chen, Yuan Sui, Hanjv Sun, Michael Wisniewski, Yongsheng Liu, Jia Liu Biological control of postharvest diseases, utilizing wild species and strains of antagonistic yeasts, is an eco-friendly management approach that has received considerable attention over the past three decades. A few yeast-based biocontrol products are either in advanced stages of development or commercially available. Ecological fitness, stress tolerance and biocontrol performance are essential attributes for ...

Exacerbation of photosynthetic damage through increased heat–light stress resulting from Gargaphia decoris sap-feeding
Publication date: March 2016 Source:Biological Control, Volume 94 Author(s): Blair W. Cowie, Marcus J. Byrne, Ed T.F. Witkowski, Nic Venter Solanum mauritianum (Bugweed) is one of the world’s worst ecological weeds, being targeted for biological control in South Africa since 1984. One of two promising biocontrol agents released against S. mauritianum is a sap-sucking lace bug, Gargaphia decoris (Hemiptera: Tingidae). There are few studies on physiological changes induced by feeding damage of biological control agents on their target weeds. Chlorophyll removal by G. decoris feeding caused metabolic impairment wh...

Puccinia araujiae, a promising classical biocontrol agent for moth plant in New Zealand: Biology, host range and hyperparasitism by Cladosporium uredinicola
Publication date: April 2016 Source:Biological Control, Volume 95 Author(s): Freda E. Anderson, Silvina P. Santos López, Romina M. Sánchez, Cintia G. Reinoso Fuentealba, Jane Barton The rust fungus Puccinia araujiae is proposed as a biological control agent for moth plant (Araujia hortorum) in New Zealand. This pathogen completes its life cycle on this host, it has the capacity of damaging it by producing premature foliage senescence and defoliation, and, it is only known from members of the Oxypetalinae (Apocynaceae). P. araujiae was found to be heavily hyperparasitised by the fungus Cladosporium ured...

Non-consumptive predator effects on a primary greenhouse pest: predatory mite harassment reduces western flower thrips abundance and plant damage
This study demonstrates that NCEs of predatory mites can induce a trophic cascade by reducing pest feeding and fitness. Such beneficial effects of natural enemies are often overlooked in simple predation and efficacy studies. Graphical abstract (Source: Biological Control)
