Home > Biology > Biology Project to Study Bio-Insecticides And Pesticides Biology Project to Study Bio-Insecticides And Pesticides To study the importance, usage and preparation of bio-insecticides and pesticides Introduction Today the rapid increase in population and demand of food materials has initiated the large use of insecticides and pesticides. These toxic chemical insecticides and pesticides are resulting in harmful effects and biomagnifications due to which our environment is continuously polluting and fertile lands are acquiring infertility. No doubt they are providing hopeful results in eradication of insects, pests and diseases but they are also killing useful organism present in soil due to which the fertility of the soil is rapidly declining. The conventional farming practices which uses chemical methods to kill both useful and harmful life forms indiscriminately, resulting in the malfunctioning of food chain and food web. Biocontrol is the best method to cope with the losses done by the chemicals. In these method insects, pests and pathogens are removed using biological methods without harming the environment and other organism. This is based on natural predation rather than introduced chemicals. The use of bio-insecticides and pesticides also comes under this category. Today due to awareness about the harmful effects of the chemical insecticides and pesticides, most of the farmers are diverting towards the organic farming. In our local area many such plants, waste matter etc. are available from which these bio-insecticides and pesticides can be prepared by using natural means only. Conventional pesticides are generally synthetic materials that directly kill or inactivate the pest. Being single chemical entity, chemical pesticides have resulted in increased resistance in pests. Bio pesticides also known as Biological Pesticides are pesticides derived from natural projects.icbse.com/biology-339 1/9 6. It is made by the centrifugation of curd in which byproduct ghee (fats) is also obtained. The dairy products can also prove a major alternative in controlling the insects and pests in farmlands. Organic agriculture is a unique production management system which promotes and enhances agro-ecosystem health. iv. and this is accomplished by using on-farm agronomic. preventing the plant. This distasteful butter milk can be used to make the projects. vii. viii. Different types of bio-insecticides and bio-pesticide 1. bacteria. i. The use of bio-insecticides and bio-pesticides also fall under this category only. v. 2. 4. biological cycles and soil biological activity. This project is mainly based on the preparation. Organic farming generally produces somewhat lower yields but sustains better yields during drought years. uses few and always natural pesticides. ii. 8. leaches dramatically fewer nitrates. effects and advantages of bio-insecticides and bio-pesticides. iii. 7. 3.com/biology-339 2/9 . as farming goes hand in hand with cattle rearing. plants. Fermented Curd Water In many states of rural India milk production is the main occupation associated with the farming also known as dairy management. allowing it to reap higher yields in some cases. Due to pungent and bad smell of the extract most of the pests and insects which are attracted due to nectar and fragrance get repelled. Studies thus far have shown that organic farming requires less water. Effects and advantages:1. 2. We will here use the cow urine for the control of pests and as a growth promoter for the growing crops. an important antioxidant. the pests and insects etc. and has been shown to have improved nutrient qualities including as much as double the flavonoids. Cow Urine Fermented curd water Dashparni Extract Neem -cow urine extract Mixed leaves extract Chili –garlic extract Broad spectrum formulation 1 Broad spectrum formulation 2 Cow Urine Extract In India. Any religious ceremony and rituals can’t be performed without cow urine which is commonly known as gomutra. It has acquired an important place in the hindu religion since ancient times. 5. One of the dairy product known as butter milk or Chaach can be used for this purpose.12/24/13 Biology Project to Study Bio-Insecticides And Pesticides materials as animals. vi. prevents soil erosion.icbse. including biodiversity. Bio pesticides are less toxic and also reduce the pollution problems caused by conventional pesticides. There is much greater demand of butter milk in the summer season and it gets distasteful if it is kept for more than two days. biological and mechanical methods in exclusion of all synthetic off-farm inputs. and certain minerals. will not attack the leaves and buds of the crop plants. usage. therefore the cow urine is available easily in the rural areas. Preparation and application: Collect 5 liter of pure and concentrated cow urine and dilute it with 40 liters of water and spray it using the sprayer in one hectare of field at the evening time.
