Insecticides we use
Insecticides as just one kind of pesticide play an essential role in the control of insect pests that are in various ways harmful to man.
Those intimately involved in insect control May gain a broader perspective by knowing something about the history of insecticides and should be familiar with both the action of insecticides (i.s. That is how they gain entry into the body and how and where they may act) and the various properties of insecticides.
An important aspect of insecticide usage that can determine it's effectiveness is the development of insecticide resistance in some strains of insects. Most insecticides presently used in Urban Pest Control can be categorised into one of several types of insecticides.
Botanical - pyrethrins - usually applied as a non-residual space spray for flushing and fast Knockdown. natural pyrethrins are extracted from certain Daisy's mammalian toxicity is relatively low.
Botanical insecticides sometimes referred to as natural or plant-derived insecticides are extracted from specific parts of certain plants. as such they have a long history of use. nicotine Extracts from tobacco were used as insecticides as early as the late 1600s.
The most widely used Botanical insecticide is pyrethrins which are obtained as an oil extract from the flowers of a daisy-like plant. currently, Kenya is the world's biggest supplier of pyrethrins. Its main areas of use include the control of the various household and industrial insect pests, insect pests of stored products and garden pests. Its wide range of applications can be attributed to a number of characteristics
Broad-spectrum of Activity
Low mammalian toxicity
Rapid breakdown after application
Fast knockdown flushing and repellent properties.
Synthetic pyrethroids - permethrin - bioresmethrin permethrin is used mostly as a medium-term residual surface spray for the control of a variety of household insect pests. A vast range of other synthetic pyrethroids is employed in supermarket type aerosol sprays. Mammalian toxicity tends to be relatively low.
Following the insecticide developments that occur during and soon after the Second World War, there was a need to widen the gap between an insecticides toxicity to the target insect and it's toxicity to higher animals including man. one area of research and development that has achieved much in this regard involved the synthetic pyrethroid insecticides. very broadly the development of synthetic pyrethroids arose out of a close examination of the biologically active natural pyrethrins developed from a structure of natural pyrethrins.
Since the early 1950s, a wide range of synthetic pyrethroids has been developed and marketed. tailoring and refining of the pyrethroids have over years lead to improvements such as quick and knockdown greater toxicity to Target insects increased safety 2 mankind and in some cases greater residual action. many of these insecticides are among the safest insecticides available.
As well as in crop protection and stored product pest applications pyrethroids are very widely used in supermarket type household aerosol sprays where the safety factor is clearly very important. extensively used synthetic pyrethroids include bioresmethrin, d-phenothrin and tetramethrin permethrin is a recently developed pyrethroid that owing to its broad spectrum of activity against the range of household pests its safety demand and its residual action has much to offer in Urban pest control practices. synthetic pyrethroid technology is likely to play a very important role in the future of many pest control applications.
Registration of pesticides
The registration system for Insect pesticides is administered in each state by an appropriate state government department usually the Department of Agriculture Department of Health. the process of registration is designed to facilitate the task of officially regulating and controlling by qualified and authorised pest control companies the manufacture, sale, storage, use and handling of these potentially harmful materials. (Insect killers)
It is important to note that the registration authorities of each state may differ in their assessments of submissions for pesticide registrations, as a result, the recommended uses for a particular pesticide may Vary from state to state. so it is essential to read The Label before purchase and use. by proving information contained on the label of a pesticide the registration authority can ensure that pesticides are used effectively efficiently and safely. if used according to label directions. Pesticide users must use the product precisely as the directions indicate and must not use the product for any purpose other than those indicated on the label
Various kinds of legislative control ancillary to pesticide registration operate in various States. such legislation mostly incorporates a licensing scheme for pest control operators and may outline regulations pertaining to the use of certain more hazardous pesticides.
pest control operators in a given state should be entirely familiar with the pesticide legislation that operates in that state.
