[Accessed 6 February 2018]. This handbook was created by the Environment Protection Authority, which is part of the Government of South Australia. All the information has been sourced from people registered and trained to apply large amounts of herbicides to large areas invested by weeds. This source is a primary source as all the information within was sourced directly by the people who have complied this handbook.

Restoring natural vegetation can also help to reduce the presence of weed species. It is very important to draw up a plan before tackling a weed infestation. This ensures all aspects of the problem are considered and helps in achieving the desired results.
When planning your approach, you need to ask yourself these questions: what type of water body is it? What type of weed are you trying to remove? And do these weeds have any value at the site in question ie. Act as a buffer to control erosion, and assist in obtaining cleaner water via filtration. Considering these questions help in determining which herbicide is required, the time for application and the method needed for optimal success.
There are three basic types of herbicides: pre-emergent, which inhibit the germination of weed seeds; knockdown herbicides which are directly applied to an already growing plant; and selective herbicides, which act only on one type of pest plant, bring specifically suited for it. Along with all of these herbicides, it is wise to consider an integrated pest management approach method; this combines other methods with minimal herbicide use in order to be eco-friendlier on the

It is very important to understand the warning labels on the product and to read the toxicity rating of the product. One must read the ‘directions for use’ very closely, ensuring one knows exactly how to use the product and what quantities to apply. When mixing the herbicide, it must be done in a well ventilated area, one must be wearing Personal Protective Equipment (which will safeguard one against poisoning; extensive list of gear needed is provided in the source) and follow the instructions very carefully.
Before beginning to spray, one needs to do a thorough risk assessment considering everything from physical characteristics of the area to the related human health issues. Once this has been completed and it is deemed necessary to spray with herbicide, a trained professional should do so. They are well educated of the risks and also how to do it effectively, reducing stray drift via the air which can affect human health, trade and the
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 foam 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.

The pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.
What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.

“(Silent Spring) spells out in memorable detail through out the book the effects of synthetic insecticides and herbicides on water, soil, plants, wildlife, fish and human beings. But in the book’s final chapter she suggests alternative courses of action for mankind —- a way out of this march toward death.” (Holmes, Pg. 123)

cons.], perennial ryegrass (Lolium perenne L.), and creeping bentgrass (Cudney et al. 1997, Dernoeden 1987, Neal et al. 1990). Herbicidal control options of smooth crabgrass and goosegrass in creeping bentgrass also include quinclorac, bensulide, fenarimol, and mesotrione. Previous research, however, has shown stunting, thinning, or foliar phytotoxicity to both mature and immature cool season turfgrasses including creeping bentgrass with varying rates and application timings of many of these herbicides as well (Busey, 2003; Cudney et al. 1997; Dernoeden, 1987; Mueller-Warrant, 1990; Neal et al. 1990; Warren et al. 1989). Currently, only bensulide and fenarimol are explicitly allowed for PRE crabgrass and goosegrass control on creeping bentgrass putting greens (Anonymous, 2009; Anonymous, 2010). Given these limited options for controlling troublesome grass weeds in creeping bentgrass, new herbicidal control options with limited creeping bentgrass injury would prove beneficial.
As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should
Instead of using pesticides in farming a better alternative would be biological control. This is when a natural predator is released into the crop growing area as a result the number of pests can be reduced.
The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil, in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the soil was severely damaged from monoculture (The cultivation of a single crop in a defined area).... ... middle of paper ... ...
There are 2.5 billion pounds of pesticides being applied to agricultural products each year in the United States. This is ten times more than was applied forty years ago. It is still unknown as to what type of exact effects these chemicals may have on individuals. Some farmers that have been using pesticides in their fields and developed leukemia are finding that the cause of their disease is from inhaling pesticides. These chemicals are still in use today and most of them have never been tested for the short or long-term effects that they may have on humans.
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
