are substances found in microorganisms and vegetation and their dutyis to protect vegetation from being attacked by insect. Note thatthey naturally live in these microorganisms. They can also be definedas pesticides naturally obtained from natural resources likevegetation, certain minerals, animals and bacteria (Bailey, 2012). are not only engaged in control of insects, but alsoprevention of nematodes, weeds and diseases to help the vegetationbecome more productive as well as good vegetation physiology. Thistechnology is being embraced due to its wide scope of advantages andsuccess in terms of programs put in place for pest management. has in the previous year’s been regarded as the mostsuccessful form of pest elimination in comparison to other methods ofpest control in agriculture. This is mostly discovered successful inorganic farming. Biopesticide technology has restrained as well ascompletely eliminated fungi, malicious insects, nematodes and alsobacteria with complex fibers around the world’s farmlands (Bailey,2012).
Thereare three categories of biopesticides. They are Biological ControlAgents, Microbial pesticides and Biochemical Pesticides. Everycategory contains a huge variety of products each product having itsown exclusive utility. As noted by Joshi (2006), biological ControlAgents are used for the incorporated pest control like parasitoids,predators, pathogens and nematodes. Microbial Pesticides has amicroorganism which is genetically or naturally produced. This activeingredients used are protozoa, viruses, nematodes, fungi, yeast andbacteria. Biochemical pesticides are naturally obtained materials forpest control but user friendly to mammals. This non-toxic modeaffects the normal growth of a pest, the pest’s ecology or thepest’s reproduction ability (Bailey, 2012).
Severalbiopesticides have been discovered by scientist through study ofvegetation chemistry. Ways that vegetation provides control of pestsare Plant growth regulation, insect growth regulators, fungicidalcontrol, and mechanical control and induced resistance. In plantgrowth regulation, extracts from some plants act as contactherbicides using various mechanism. The mechanisms are production ofenzymes, amino acid synthesis inhibition and cell membrane disruptionin tissues of the plants. In insect growth regulators, insects areprevented from reaching their reproductive stage by the extracts.Fungicidal control is similar to plant growth regulation, extractsfrom some plants act as contact fungicides (Bailey, 2012). There isdisruption of cell membranes which deactivates major enzymes hencemeddling with the metabolic procedures. In mechanical control,dominant natural agents from other vegetation consume the weeds. Ininduced resistance, crops are treated with extracts from plants.These crops accumulate high levels of specific proteins inconjunction with compound that restrain bacterial and fungal diseasedevelopment.
Biopestcidespresents a good future and does not affect the farmer’sprofitability. It is safe for the crop as well for the health of thefarmers. There is reduction in synthetic chemicals which means afavorable environment. Due to the high demand of a toxic freeenvironment worldwide, biopesticide technology has been accepted withwide arms (Koul, 2002). Farmers and consumers have become more awareof the significance of keeping the environment clean. Biopesticidetechnology has proven to be the best farming technology for the timesince it is environmental friendly. It is also covering up for thechallenges the farmers are facing today. Non-target organism’simpact is minimal, residues and toxins are not harmful, and residueis manageable, flexibility in harvest and labor, provision of safetyfor the environment and workers (Bailey, 2012).
Asnoted by Joshi (2006), farmers are at an advantage of this technologysince it will help them change from the highly toxic knownconventional methods of chemical application to the environmentalfriendly application. Some of these advantages are flexibility inharvesting, the residues are not hazardous, it does not harm insectsthat are beneficial, it is quite effective in resistance management,environmental friendly, lucrative export markets accessibility,workers are ensured of their safety, predictable pesticides arereduced drastically and they can be utilized in organic andconvectional agriculture. Pest management center is obligated toproviding farmers with low risk agriculture. They economically andenvironmentally provide tools for pest control which includebiopestcides. They are also competitive in nature. Institutions orpersons that work closely with PMC include biocontrol industry,international experts, pest management regulatory agency, and growerrepresentatives to help in proper utilization of biological controlproducts. PMC also provide regulations in relation to biopesticidesutilization, advice the biopesticides researchers along withrepresentatives of this industry regarding regulatory and scientificissues, provides information on the upcoming tools of pestmanagement. This encourages the shareholders and researchers toexecute the technology with confidence. Through the support of PMC,biopesticides are developed and integrated into systems that areeasily manageable (Joshi, 2006).
Biopesticidetechnology has received positive response from the public. It has notonly brought economic gains to the public through exports of theproducts but the products are also used without fear of contractingdiseases as is mostly common with convectional pesticides. Residuestend to be seen with the use of convectional pesticides. Theseresidues turn up in drinking water and food supply as well pollutingthe environment. Spraying the pesticides can also bring diseases tothe persons using them. Conditions have to be set for the pesticidesto ensure residues are not in the levels that can cause harm whilethat is not the case for the biopesticide technology. There is also alimit of food residues for the pesticide grown plants and not thecase for the biopesticides. The technology has affected me in apositive way in that this technology has brought about prevention ofdiseases as well as production of healthy food stuff. The environmentis also conducive in areas where this technology in practiced (Koul,2002).
is seen to have more advantages than disadvantages. It is therefore aquite recommended technology in the modern time. It is not onlybeneficial to the farmers but to everyone. When it comes toenvironment, it is quite friendly since it ensures the environment iskept clean. The consumers of these plants are also comfortable usingthe products of biopesticides technology since they have no fear ofcontracting insidious diseases. Farmers are at an advantage of thistechnology since it will help them change from the highly toxic knownconventional methods of chemical application to the environmentalfriendly application. Since biopesticides has been regarded as themost successful form of pest elimination in the past years incomparison to other methods of pest control in agriculture. Thetechnology has been embraced and its wide scope of advantages andsuccess in terms of programs put in place for pest management. Thetechnology provide flexibility in harvesting, the residues are nothazardous, it does not harm insects that are beneficial, it is quiteeffective in resistance management, environmental friendly, lucrativeexport markets accessibility, workers are ensured of their safety,predictable pesticides are reduced drastically and they can beutilized in organic and convectional agriculture, I would vouch forthis technology anytime and any moment.
