Weed Kill Experiment Report :: essays research papers

Weed Kill ReportABSTRACT - The objective of this experiment is to determine which of three weed vote down rules will be most successful in gobble uping the Cobblers peg weed over a five day period. Two of the weed fine-tune methods are natural - boiling water and vinegar solution. One of the weed kill methods is a weed spray Yates ZERO. The most effective weed kill was found by examining how fast and effectively each weed kill treatment killed its group of seventeen weeds which were separated into one of three spume boxes over a period of five days. The most successful method was found to be one of the natural methods, boiling water. The next best method was the herbicide and then the least successful method was the vinegar solution which killed none of its weeds. INTRODUCTION My initial observation was that simple conservation actions such as reducing the use of pesticides can achieve measurable improvements in habitat quality and environmental health. Herbicides are toxic to most mammals as well as to the beneficial insects that you want to encourage in your garden. Sometimes herbicides seep into the ground water causing contamination of which the long term effects are non known. Herbicide application can also result in drift or movement in the soil, this endangers wanted vegetation nearby. Herbicides are used out-of-the-way(prenominal) too rampantly. Excessive use of toxic herbicides is used when not necessary and because most are not aware of the many other natural alter primordials. We must(prenominal) find more ways to cut back on the use of chemical herbicides and change to biological weed control methods. Foreign plants which turn into weeds are continuously being introduced to Australia both accidentally and intentionally. They can cause extreme damage to Australias environment, as they threaten the survival of many native plants. They are successful in growing as they - usually grow faster than native plants competing for nutrients, water, sp ace etc, they survive better as they do not have the pests and diseases that would normally control them in their natural habitats, they take over the native plants that the native animals use for shelter, food and nesting. The Cobblers peg (Bidens pilosa) also known as farmers friend, Spanish needle and beggars tick was introduced from South America and has become a weed in Australia. Individual flowers are yellow with white petals and do not last for very long, eventually turning into seeds.
