Biocontrol of stem end disease agent, Alternaria alternata YZU, on pitaya is more interested in altering the application of chemical pesticides. This study was conducted to characterize antagonistic phosphate solubilizing bacteria (PSB) from rhizosphere soil for their biocontrol activities against A. alternata YZU under laboratory and greenhouse conditions.

Chitinolytic bacteria and their chitinases have attracted great attention due to potential applications in various fields, including medicine, food processing, agriculture. To develop a novel type of biocontrol agents alternative chemical agents for phytopathogenic controlling, we focus on bacteria possessed high chitinase activity. In this study, a chitinase gene (chiB) from Bacillus velezensis RB.IBE29 was identified, cloned, and analyzed.

In vitro analyzing the antagonistic activity of seventy native bacterial isolates towards plant tumorigenic Agrobacterium tumefaciens resulted in a selection of eight potential biocontrol agents. These isolates were screened for their antagonistic effect in vitro as well as their efficacy in reducing gall formation in planta.

The rose sawfly, Arge rosae L. (Hymenoptera: Argidae), is one of the most destructive pests of roses grown both indoors and outdoors in Antalya province (south-western part of Turkey). Especially in greenhouse rose cultivation, growers depend heavily on synthetic pesticides to control this pest along with other arthropod pests in their crops. The aim of this study was to evaluate biocontrol potential of some indigenous soil-borne entomopathogenic fungi (EPF) against the pest. In pathogenicity assays, a total of 17 EPF isolates, belonging to three species [Beauveria bassiana (Bals.) Vuill.

Their management relies primarily on agrochemicals with short persistence; widespread use of these chemicals causes environmental and human health problems. The challenge of sustainable viticulture is to provide ecologically sound alternatives. In this regard, the application of entomopathogenic nematodes (EPNs) and natural products derived from their symbionts can be an alternative. EPNs are well-known biocontrol agents for soil-dwelling insects.

Wireworms are polyphagous soil-dwelling pests that are hard to control. Attract-and-kill strategies, combining attractive semiochemicals with biocontrol agents, have great promise to control insect pests. We hypothesized that the combination of plant semiochemicals and entomopathogenic nematodes (EPNs) in an attract-and-kill system could greatly enhance the nematodes’ efficiency against wireworms. We evaluated the potential of alginate beads loaded with plant extracts and EPNs to control Agriotes obscurus.

In Turkey, Tinocallis (Sappocallis) saltans (Nevsky) on Ulmus glabra Hudson was detected for the first time, and it was determined that it caused a considerable amount of damage. The study was conducted for the purpose of determining the usability of enthomopathogens in the control against it, while avoiding the negative effects of chemicals on the environment and human health. A total of 12 bacteria strains were tested for control efficacy and verified: Brevibacillus brevis (2), Bacillus thuringiensis (1), Bacillus thuringiensis subsp. kenyae(2), Bacillus thuringiensis subsp.

Enterobacteria of the genus Providencia are mainly known as opportunistic human pathogens but have been isolated from highly diverse natural environments. The species Providencia vermicola comprises insect pathogenic bacteria carried by entomoparasitic nematodes and is investigated as a possible insect biocontrol agent. The recent publication of several genome sequences from bacteria assigned to this species has given rise to inconsistent preliminary results.

Though it is toxic to humans, dichlorvos is a widely used chemical pesticide and plays an important role in the control of plant pests. The application of a combination of the biocontrol agent Trichoderma with dichlorvos may reduce the need for chemical pesticides. Therefore, revealing the specific molecular mechanism of Trichoderma tolerance to dichlorvos has become particularly important.

So far, biocontrol agent selection has been performed mainly by time consuming in vitro confrontation tests followed by extensive trials in greenhouse and field. An alternative approach is offered by application of high-throughput techniques, which allow extensive screening and comparison among strains for desired genetic traits.

Trichoderma spp. are effective biocontrol agents for many plant pathogens, thus the mechanism of Trichoderma-induced plant resistance is not fully understood. In this study, a novel Trichoderma strain was identified, which could promote plant growth and reduce the disease index of gray mold caused by Botrytis cinerea in cucumber.

Important to study about the effects of fungicides on the biocontrol agent. The combined use of biocontrol agents and chemical fungicides has attracted much attention as a way to obtain synergistic or additive effects in the control of soil borne pathogens (Locke et al., 1985). Considering this possibilities, present study was conducted.
