There are benefits and shortcomings of using a variety of methods of pest controls. Examples of pest control methods include the use of pesticides and using genetically engineered crops.
Any substances used to “control” different types of pests. These “pests” include plants and animals. Four common types of pesticides include herbicides, fungicides, rodenticides and insecticides.
A substance that is toxic to plants often used to kill off unwanted plants or vegetation. Herbicides can be designed to be selective or non-selective. Selective herbicides are designed to kill specific kinds of vegetation and non-selective herbicides kill all plants. One “herbicide” that has been in the news recently you may have heard about is Roundup. Monsanto is a company that makes Roundup and the ingredient glyphosate has been linked to cancer in humans.
Chemicals or biological organisms (biofungicides) that are used to kill parasitic fungi and their spores. A fungicide purpose is to inhibit growth. A fungus (fungi) can cause severe problems due to the loss of viable crops. Free living bacteria or fungi can be biofungicides.
Pesticides used to kill rodents. Rats, mice, squirrels and porcupines are examples of rodents. Some rodenticides are lethal and others may require more than one exposure.
Substances that kill insects. Different types of insecticides can be used to repel insects and be tracked back to their nest, like an ant. These chemicals often kill organisms indiscriminately and end up killing ‘good’ insects accidentally. Bee populations are in collapse globally due to exposure to insecticides.
