AGRI QATAR - Bio Pesticides
What is Bio-pesticide?
» An aspect of Biological control that uses natural enemies such as pathogens, parasitoids and/or predators to manage insect and mite pest populations.
» Biopesticides may be derived from animals (e.g. nematodes), plants (Chrysanthemum, Azadirachta) or micro-organisms (e.g. Pseudomonas, Trichoderma, nucleopolyhedrosis virus), and include living organisms (natural enemies) etc.
» Biopesticide is a formulation made from naturally occurring substances that controls pests by nontoxic mechanisms in an ecofriendly manner.
Microbial Pesticides
» Refers to any living microorganism such as bacteria, fungi, nematodes, viruses, protozoa, parasitoids and predators that controls pests by biological non-toxic means.
» Microbial pesticides are composed of microscopic living organisms (viruses, bacteria, fungi, protozoa, or nematodes) or toxin produced by these organisms.
» Microbial pesticides includes insecticides, fungicides, herbicides and growth regulators of microbial origin.
Benefits and Advantages
» Increase crop yield by 20-30%.
» Inherently less toxic than conventional pesticides.
» Affect only the target pest and closely related organisms.
» Effective in very small quantities and often decompose quickly.
» Crop yields remain high.
» Cheap, renewable and can be handled safely.
» Difficult for insects to develop resistance to these pesticides.
TADMIR -PSEUDOMONAS FLUORESCENS
Contains Pseudomonas fluorescens bacteria which controls many plant diseases. The organisms release antibiotics which compete with plant pathogens and suppress their growth and kill them or reduce their growth rate.
TADMIR-METARHIZIUM ANISOPLIAE
Contains insect parasitic fungus Metarhiziumanisopliae,a natural inhabitant of soil. It has the ability to attack the insects and cause green muscardine disease and eventually kills them in 3-4 days.
TADMIR -BEAUVERIA BASSIANA
Contains fungus Beauveriabassiana, a natural inhabitant of soil capable of causing white muscardine disease in many insects.The fungus attacks the cuticle of pest insect and consumes body sap leaving the insect’s exoskeleton..
TADMIR - TRICHODERMA VIRIDE
Contains Trichodermaviride fungi, a biofungicide which controls many plant diseases. Trichodermaviride produces antibiotic substances that kill or suppresses several plant pathogens.
TADMIR - TRICHODERMA HARZIANUM
Contains the entomophagous fungi Trichodermaharzianum. Known as the soil army of plants, protects the root system of plants by competing for nutrients and space..
