The purpose of this research project is to study the effect of using pesticides on plant growth. The study also aims to identify the nature of effect of pesticides and whether all ingredients in pesticides have safe effect on plant growth or not.
It was found that excessive use of pesticides on plants affects the rate of cell division.
Three different types of plant were used. Namely, Cactus, Segade, Rehane). Four trials were performed for each type of plant. In addition, three different types of pesticides were used in the experiments.
The following procedures were performed during experimentations:
- Three types of pesticides were labeled (A,B,C)
- Three types of plants were identified as test plants and labeled (A, B, C) while a control plant was labeled (D)
- Length of plants were measured and recorded (initial values)
- Each pesticide was sprayed on its similar letter plant
- Length of plants were measured repeatedly every 3 days for a period of one month
- Data were plotted in a graph for analysis and interpretation
In conclusion, it was found that pesticide (B) with Diazinon caused the most delay in plant growth
