Bio pesticides and economic approach for pest management

Bio pesticides and economic approach for pest management

  • It is hearting to observe the growing awareness among the farmers and policymakers about ecologically sustainable methods of pest management.
  • More and more farmers are coming to realize the short-term benefits and the long-term positive effects of the use of bioagents and other ecologically safe methods to tackle pest.
  • Biopesticides are certain type of pesticides derived from such natural materials as animal, plant ,bacteria and certain minerals.
  • Example canola oil and baking soda have pesticide application and are considered as biopesticides.
  • The use of this material is whispered with application to foliage, turf, soil or other environment of the target insect pest.
  • In a very simple way we can say that pest management tools that are based on beneficial microorganism like bacteria, virus fungi ,protozoa.
  • Benefits of biopesticides include effective control of insect plant disease and weeds as well as human and environmental safety.
  • Biopesticides also play an important role in providing pest management tools in areas for pesticide resistance markets and environmental concern limit the use of chemical pesticides product.
  • Biopesticides in general have a narrow target range and a very specific mode of action which are slow in acting but have relative Lee critical application times.
  • Suppress rather then eliminate best population.
  • It is safer to humans and the environment than conventional pesticides.

25 million cases of acute occupational pesticide poisoning in developing countries are being reported each year.

Advantages of using biopesticides

  • Biopesticides are best alternatives to conventional pesticides and usually inherited less toxic than conventional pesticides.
  • Biopesticides are often effective in very small quantities and often decompose quickly thereby resulting in lower exposures and largely avoiding the pollution problem caused by conventional pesticides.
  • When used as a fundamental component of integrated pest management program biopesticides can greatly decrease the use of conventional pesticides while crop yield remain high.
  • Biopesticides generally effect only the target best and closely related organism in contract to broad spectrum conventional pesticides that may affect organism as rent as birds, insect and mammals.

Types of biopesticides

Biopesticides fall into three major classes:-

(1) Microbial pesticides consists of a natural occurring and genetically controlled microorganism as the active ingredients.

  • This pesticides can control many different kinds of pest all the each separate active ingredient is relative le specific for its target pest.
  • for example there are fungi that controls certain weeds and other fungi that kill specific insect.
  • They suppressed pest by producing a toxin specific to the pest.
  • Preventing establishment of other microorganism through competition or other mode of action.

(2) Plant incorporated protectant is pesticide substance that plant produce from genetic material that has been added to plant.

  • As example scientist can take the gene for the BT pesticides protein and introduced the gene into plants own genetic material after that the plant instead of the beauty bacterium manufacture the substance that destroy the pest.

(3) Biochemical pesticides are naturally occurring substances that control best by non toxic mechanism.

  • Conventional pesticide by contrast are generally synthetic material that directly kill or inactive the pest.

Potential of biopesticide

  • The efficacy of many of the biopesticide can equal that of conventional chemical pesticides.
  • However the mode of action will be different.
  • With many of the bio pesticides that time from exposure to morbidity and death of the target insect maybe 2 to 10 days.
  • Understanding the fundamental difference in the mode of action of bio pesticide versus traditional pesticide is important since the use pattern of bio pesticide may be different from traditional pesticides to control a particular pest species.
