Since the dawn of time, agriculture has been the centre of humanity, where there was fertile land, there were humans. As time went on, this has not changed significantly, the biggest threat to crops now or thousands of years back in time, is still insects. As technology as improved, techniques for eliminating these insects has changed substantially. The most populate method in today’s age is insecticide; chemicals which kill insects, however as sometimes due to gene mutation some insects are born with defects which give them resistance or immunity to some insecticides, while other insects die from those insecticides, they survive and then procreate, and the gene mutation passes down the generation. Substitutes to chemical insecticides include; …show more content…
Biological pesticides kill pests in a different fashion to chemical pesticides as they do not use chemicals, instead they utilize organic methods instead of synthetic methods. A biological pesticide is a fungi or other such organism which preys on the pest and does not inflict any harm on the crop or the surroundings. Bacillus Thurigensis is one such biological pesticide which is commonly used as a biological pesticide to destroy several different types of insects. The bacterium acts by producing and releasing crystal proteins which have insecticidal properties which when ingested by the insect, kills it. Subsequently, since bio pesticides consist of organisms such as bacteria and fungi, pests find it harder to grow resistance to the bio pesticide, if at all. Good Bio pesticides also usually display no toxicity to any other organisms other than the ones which are being targeted (compared to DDT and the effect on birds and their eggshells) and they require a much smaller quantity in order to be deadly. Bio pesticides for the most part decompose quickly versus the pollution caused by pesticides and are far more sustainable compared to synthetic alternatives. Although research in the creation of bio pesticides may be expensive, in the long term, the bio pesticides are relatively inexpensive to create and overall are more value orientated than normal pesticides. Bio pesticides also do not leave residue on the crop and are therefore more suitable in the eyes of consumers. Bio pesticides however still cause questions in the light of efficacy, as with chemical pesticides it is easy to predict what effect the product will have, while with bio pesticides, questions arise on the matter of where the organisms may fit into the ecosystem and whether they will work instantaneously or require time to work effectively. Bio pesticides also kill far slower, compared to synthetic pesticides and that may also be
