...sucking pests. Different biocontrol agents are being used for the management of these sucking insect pests. Neoseiulus barkeri (Acari: Phytoseiidae) has been proved as an efficient acarine predator of sucking insect pests of different crops. This predator has also been reported from different localities of Pakistan. The main objective of this study was to screen out locally used pesticides i.e., pyriproxyfen, acetamiprid, chlorfenapyr, diafenthiuron and thiacl...

...to be the most efficient biocontrol agent by parasitizing the maximum number of eggs, whereas D. oviparasitica appeared to be the least efficient after 72 hours. The greatest numbers of cysts and eggs were found to be colonized with L. muscarium during microscopic observations. In the greenhouse experiment, L. muscarium had significant effects in reducing the nematode population in soil compared to the other treatments. In regard to the growth parameters,...

Screening of chilli microflora and other biocontrol agents for their antagonistic effects on Colletotrichum spp. infecting chillies
... germplasm collection of biocontrol agents were tested for their antagonistic effect on Colletotrichum gloeosporioides and C. capsici by dual culture test. Among the isolates of chilli microflora tested, Aspergillus flavus showed 70.2% inhibition of C. gloeosporioides and 54.9% inhibition of C. capsici.Among the isolates of Trichoderma sp. tested, T.virens (Tvs-KSD isolate) and T. pseudokoningii (Tpk-1) showed highest percent inhibition of C. gloeosporioides (...

Biological control of plant diseases
...A considerable number of biocontrol agents have been established successfully for their bioconrol potential including strains belonging to bacterial genera such as Agrobacterium, Pseudomonas, Streptomyces and Bacillus, and fungal genera such as Gliocladium, Trichoderma, Ampelomyces, Candida and Coniothyrium. Trichoderma and Pseudomonas fluorescens are the most important and widely used bioconrol agents being used across the world for the management of several ...

Cation exchange resin (CM-Sephadex C-25) was used for the isolation of lactoferrin using the fast protein liquid chromatography. The lactoferrin was further characterized through sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Disc diffusion method was applied for the evaluation of antibacterial activity of lactoferrin. Minimum inhibit...
