Investigatory project Essay

Pest is an organism that is damaging to livestock, crops, humans, and land. Because of this problem, this study was conducted by the researchers by using garlic and black pepper after they found out that these materials have the ability to control pests. The materials were 2 whole garlic, 40 grams of black pepper, 600 ml of water, beaker, Erlenmeyer flask, tripod with wire gauze, alcohol lamp with denatured alcohol, mortar and pestle, knife, chopping board, 4 spray containers, and 150 pests. There were five treatments tested with three replicates each. Treatment A (garlic only); treatment B (black pepper only); treatment C (mixture of garlic and black pepper);treatment D(commercial pesticide) and treatment E(no pesticide applied).

The researchers used Complete Randomized Design (CRD) as their experimental design and the statistical test of significance used was Analysis of Variance (ANOVA). After testing, the researchers summarized the results and found out that there is significant difference between the five treatments. And the researchers concluded that garlic and black pepper can be used as an organic pesticide in controlling and irritating pests. To further improve the study, the researcher recommended the following:*test to determine the right and appropriate amount of the pesticide to be applied *test to determine the effects of pesticide (using garlic only, black pepper only and mixture of garlic and black pepper ) aside from controlling and irritating pests.
