METHODOLOGY

Aratibiotech  biopesticides’s approach places principal emphasis on primary research techniques to ensure that the foundation of business intelligence and insight is accurate, current, and reliable. Building on our decades in the science, innovation and leveraging our national research institutes  network  cum international scientists. Our teams of seasoned professionals draw upon pragmatic industrial and commercial experience to understand and interpret global impacts and local perspectives to agriculture and speciality pesticides.

Aratibiotech Biopesticides Technologies

  • Microbial species, such as fungi, viruses, or bacteria, acting as pesticides Production of antibiotics and other growth inhibitors- (Bacillus spp., Pseudomona spp., Trichoderma spp., Gliocladium spp., Streptomyces spp., etc)
    Parasitism/Predation – Coniothyrium minitans (Parasite of Sclerotinia spp.) Trichoderma spp. ( Parasite of numerous soil borne fungal pathogens) – Bacteriophages ( Viruses that infect and lyse bacteria) – Paecilomyces spp (nematophagous and entomophagous species) etcs
  • Natural materials with pesticide properties, such as diatomaceous earth, kaolin etcs.
  • Plant extracts, such as seaweed, neem, pyrethrum, oils and others as appropriate
  • Biological seed treatment, including a cross-section of technologies used as protectants and stimulants.
  • Modes of Action (MOA) Aratibiotech Biopesticides®
  1. Competitive exclusion: Many microbial biopesticides not only grow very effectively in the environments from which they were originally isolated, they can also physically occupy these niches to prevent establishment of pests and pathogens in these spaces. If these microorganisms grow well on plant leaves or in close association with plant roots, they can also provide host plants with a protective barrier against pathogens and certain pests.
  2. Production of secondary metabolites: Since bacterial and fungal biopesticide strains are isolated from very competitive environments, each produces numerous secondary metabolites for protection, survival and competition for nutrients.
  • Predation and parasitism: Some biopesticide agents physically attack and completely consume specific pathogens and pests. Other biopesticide agents actually act as parasites that feed on detrimental organisms, leading to weakening and eventual death.
  1. Induced host resistance and enhancement of plant vigour: Certain microorganisms used as biopesticides can stimulate subtle biochemical responses in host plants that enhance their abilities to resist or better tolerate pest attack and diseases. In addition, certain microbial biopesticides can also promote plant growth or enhance plant vigor by production of particular secondary metabolites and increasing availability of plant nutrients.
  2. Alteration of the soil or plant host environment: Biopesticides made from soft chemicals or biological extracts chemically or physically change conditions in the soil or on plant surfaces to be unfavorable to the establishment and growth of pests and pathogens.
  3. Disruption of fundamental biological functions, development, and structures of target organisms: Bio-rational chemicals and biological extracts can directly inhibit biochemical processes, interfere with developmental pathways of pathogens, and compromise the physical integrity of pests and pathogens.   Because of the nature and diversity of the MOAs presented above, plant pathogens and pests would need to undergo immense physical, biochemical, physiological, and genetic changes to develop resistance to biopesticides. Therefore, the loss of effective biopesticides due to development of resistant pests and plant pathogens is highly unlikely.

Key for success

  • Not curative!

Need to be used in a preventive manner.

  • Integration!
  1. There are no silver bullets.
  2. Biopesticides need to be integrated with other pest management strategies.
  • Pathogen identification!
  • Proper diagnosis is key to controlling any disease.

Advantages – No harmful residues produced, i.e. biodegradable. Can be cheaper than chemical pesticides when locally produced. Can be more effective than synthetic pesticides in the long-term (as demonstrated, for example, by the Sesame Crop  cultivation programme, see below).

Disadvantages. High specificity: which may require an exact identification of the pest/pathogen and the use of multiple products to be used; although this can also be an advantage in that the biopesticide is less likely to harm species other than the target. Often slow speed of action (thus making them unsuitable if a pest outbreak is an immediate threat to a crop).

  • Biopesticides ® Formulations

The pesticide formulation is a physical mixture of one or several biologically active ingredients which provide effective and economic control of pests.   These varied types of formulations of pesticides are intended to serve diverse needs of agriculture and public health.  These also have to be manufactured to suit different types of applications.   So far only inorganic pesticides have been in use and as an alternative now organic pesticides have come to be used.

Product  Specification & Uses
Pesticides   cover   a  wide   range  of  heterogeneous   products  which  help  in controlling the loss  of crops and  vegetation  from attack pests.  The ARATI biopesticides (which kill all pests) and ARATI  bioberbicide (which remove unwanted shrubs, weeds). The main forms of formulation available are:
1.  Power form (dusts)
2.  Weltable powders
3.  Granulated preparations
4.  Emulsive concentrates
5.  Aero sols and fumigants
6.  Other types of formulation such  as soaps, paints, pastes, waxes.

Plants are not defenseless.  The difference between resistance and susceptibility is due to the
timing of  pathogen recognition  and the expression of  defences.

  • Manufacturing Process

Various ingredients / chemicals are  weighed   and   taken   out from  stores according to pre fixed formula.   Ingredients are thoroughly mixed in mixing vessels for fermentation technology.  After uniform blending the mixture is taken out and  packed  in HDPE containers.

Production Duration:
Phase 1 –
Isolation, fermentation and biological testing.
Phase 2 –  Analytical chemistry packaging .
