  author={Cleopas Chenai Chinheya},
In this study, the biocontrol potential of Bacillus isolates was investigated in laboratory and greenhouse experiments. Five out of 70 bacterial isolates from the root-zone of crops and a goat pasture caused second stage juvenile (J2) mortality greater than 50% in vitro after 24 hours.Three of the five selected isolates (BC27, BC29 and BC31) which were isolated from the root-zone of a goat pasture caused J2 mortality greater than 80% at 108spores ml-1in vitro after 24 hours, with BC27…

of Trichoderma through genome sequencing for production of novel metabolites of various applications.


Isolation and Characterization of a Rhizobacterial Antagonist of Root-Knot Nematodes
The novel bacterial strain Jdm2 enhances plant growth and inhibits nematode activity, and has the potential to be a safe and effective microbial pesticide.
The nematicidal potential of local Bacillus species against the root-knot nematode infecting greenhouse tomatoes
Bacillus spp. were isolated from Iranian tomato fields and evaluated for their efficacy against root-knot nematodes, Meloidogyne javanica. The 52 spore-forming bacterium isolates were obtained from
Biological Control of the Root-Knot Nematode Meloidogyne javanica by Trichoderma harzianum.
It is suggested that improved proteolytic activity of the antagonist may be important for the biological control of the nematodes.
Biocontrol of root-knot nematode Meloidogyne incognita by Pseudomonas and Bacillus isolates on Pisum sativum
Pseudomonas isolate Pf1 may be used for the biocontrol of M. incognita on pea, and Pseudomona isolates were tested for siderophores, hydrogen cyanide (HCN) and indole acetic acid production because PseUDomonas isolate were more effective than the isolates of Bacillus in improving growth of pea and reducing galling and nematode multiplication.
Biocontrol efficiency of Bacillus thuringiensis toxins against root-knot nematode, Meloidogyne incognita
The results demonstrate that both crude suspension and cellfree supernatant of isolate Bt7N reduced the number of egg masses by 78% and 77% respectively, and number of eggs by 84% and 76% compared to control.
Biological Control of Meloidogyne hapla Using an Antagonistic Bacterium
Results suggest that B. cereus C1-7 can be used as a biocontrol agent for M. hapla in carrot and tomato plants, and shows complete inhibition of root gall or egg mass formation by RKN in carrot & tomato plants.
Potential use of cucumber (Cucumis sativus L.) endophytic fungi as seed treatment agents against root-knot nematode Meloidogyne incognita
Endophytic fungi from cucumber seedlings were isolated and screened for their potential to be used as seed treatment agents against Meloidogyne incognita and Chaetomium Ch1001 was considered to have the highest potential.
Suppression of Meloidogyne javanica by antagonistic and plant growth-promoting rhizobacteria.
Four rhizobacteria selected out of over 500 isolates from rhizosphere of the vegetables in China were further studied for suppression of the root-knot nematode and soil-borne fungal pathogens in
