Pest and pesticides

The term includes substances intended for use as a plant growth regulator, defoliant, desiccant, or agent for thinning fruit or preventing the premature fall of fruit. Also used as substances applied to crops either before or after harvest to protect the commodity from deterioration during storage and transport. These include the pyrethroidsrotenoidsnicotinoidsand a fourth group that includes strychnine and scilliroside.

Pest and pesticides

Pesticides are often applied by spraying, fumigating and baiting. However, not all pesticides kill the target pest. Examples include tetramethrin used in household fly sprays bipyridillium herbicides such as paraquat that are used on weeds Contact pesticides have to reach their target directly to be effective.

Other pesticides move from the site of application to another area in the pest, for example insecticides that are absorbed by foliage and move through the plant to kill chewing or sucking insects blood anticoagulants in baits for rats and mice that move from the digestive system to the bloodstream Systemic pesticides move from where they are applied to other parts of the plant to reach their target.

Pesticide persistence Some pesticides are effective for long periods of time. For example triazine herbicides remain in the soil and kill emerging weeds over the lifetime of a crop. This helps prevent pesticide build-up in crops or plants and animals that are not pests.

Pesticide Information

Pesticide resistance One risk of using pesticides is that pests may develop resistance, which means the pesticide is no longer effective. Resistance generally develops when a pesticide is applied and a small percentage of the target organisms survive. AusVEG provide guidance on managing pesticide resistance in horticultural crops.

Bactericides destroy, suppress or prevent the spread of bacteria. Fungicides are used to control or destroy fungi such as grey mould on grape vines and fruit trees downy mildew on cucumbers Herbicides destroy, suppress or prevent the spread of a weed or other unwanted vegetation, for example, the herbicide glyphosate controls a range of weeds in gardens and bushland, and on farms.

Insecticides control many insect pests, including thrips.Beyond Pesticides offers the latest information on the hazards of pesticides and least-toxic alternatives, as well as ongoing projects including children's health, pollinators and pesticides, organic food and agriculture, mosquito control and organic lawn care.

Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields.

Pesticide use in NSW

Pest management is far bigger than eliminating nuisances, it impacts the safety of our health, our food supplies, our fiber, our infrastructure and our forests. NPIC provides objective, science-based information about pesticides and pesticide-related topics to enable people to make informed decisions.

NPIC is a cooperative agreement between Oregon State University and the U.S. Environmental Protection Agency (cooperative agreement #X).

Many pest problems, such as termites or management of problems on large trees, require special pesticides or equipment and technical training for most effective management. Although professional services may be expensive, the investment may be worth it to solve a serious problem.
