The following specification particularly describes and ascertains the nature of this invention and the manner in which it is to be performed:-
FIELD OF INVENTION
[001] This invention relates to a bio-pesticidal formulation, and more particularly to a bio-pesticidal formulation comprising an extract from a group of bacterial species, which when cultured under appropriate conditions is capable of producing at least one pesticidally active substance.

BACKGROUND OF INVENTION
[002] For a number of years, it has been known that various microorganisms exhibit biological activity so as to be useful to control plant diseases. Although progress has been made in the field of identifying and developing biological pesticides for controlling various plant diseases of agronomic and horticultural importance, most of the pesticides in use are still synthetic compounds. Many of these chemical pesticides are classified as carcinogens and are toxic to wildlife and other non-target species. In addition, pathogens may develop resistance to chemical pesticides.
[003] Biological control offers an attractive alternative to synthetic chemical pesticides. Bio-pesticides can be safer, more biodegradable, and less expensive to develop. According to United States Environmental Protection Agency (EPA), bio-pesticides include naturally occurring substances that control pests (biochemical pesticides), microorganisms that control pests (microbial pesticides), and pesticidal substances produced by plants containing added genetic material (plant-incorporated protectants) or PIPs.
[004] In the recent years, the use of methods of biological control of pests has emerged to as an attractive alternative to synthetic chemical pesticides. Bio-herbicidal agents are considered safer, eco-friendly and less expensive to develop. Various bio-pesticides involving the use of various strains of bacteria have been provided earlier. However, the use of a unique combination of various strains of different bacteria in order to provide for an effective, eco-friendly, non-toxic, biodegradable and cost effective method for controlling pests is desirable.

OBJECT OF INVENTION
[005] The principal object of this invention is to provide a method and a formulation for the control of pests from a group of bacterial species, which when cultured under appropriate conditions is capable of producing at least one pesticidally active substance.
