Biopesticides serve as second-hand biocontrol agents against harmful microbial growth and supplement organic pesticides in several agricultural systems. In the production of alternative controls for synthetic insecticides to kill insect pests, biotechnology may also condone them. Bacterial fungal such Ampelomyces quisqualis Trichoderma spp., (a control agent grape powdery mildew) Bacillus subti...

Biological control agents for plant diseases are currently being examined as alternatives to synthetic pesticides due to their perceived increased level of safety and minimal environmental impacts. Fungal biological control agents have several mechanisms of action that allow them to control pathogens, including mycoparasitism, production of antibiotics or enzymes, competition for nutrients and ...

Oligandrin is an elicitin-like protein with a molecular mass of 10 kDa secreted by Pythium oligandrum. Here, the effect of oligandrin on defense response against Botrytis cinerea in tomato leaves is reported. Tomato seedlings were pretreated with 5 ml oligandrin (10 g/ml) by root submerging and then inoculated with B. cinerea. Disease severity was subsequently evaluated and compared with the co...
