Insecticides

Insecticides are any pesticides that are usually used to deter, kill or control insects. For instance, the former may use insecticides on the crops while the retailer uses insecticides in the storeroom. In the organic industry, they also use its fair share of pesticides and they are not always the same as the one used by the conventional businesses or farmers.

An insecticide is a chemical that may include larvicides and ovicides which is used against the eggs or larvae of the insects respectively. Insecticides are normally used in the industry, medicine, agriculture and general home use. The uses of these insecticides are believed to be the most major factors behind the increase in the agricultural productivity in 29th century. There are also insecticides that have the potential significantly alter ecosystems as many are toxic to humans and others are concentrated in the food chain.

There are many classifications of insecticides that are done in several different ways. For instance, the systemic insecticides are incorporated by the treated plants whereas insects can ingest the insecticides while feeding on the plants. The contact of insecticides are toxic to insects that are brought into direct contact and the efficacy is often related to the quality of the pesticides application with many small droplets such as aerosols which is very often use to improve performance.

The natural insecticides such as neem, pyrethrum and nicotine extracts are made by the plants as defenses against the insects. Nicotine base insecticides are still widely used in the United States and Canada however they are now barred in the Europe.

Plant incorporated protectants are insecticidal substances which are produced by plants after the genetic modification. For instance, the gene that codes for the specific Bacillus thuingiensis biotical protein is introduced into a crop plant’s genetic material and the plant manufactures protein. Biocide is incorporated into the plant then the additional applications will at least have the same compound that is not required.

The inorganic insecticides are normally manufactured with metals which include copper compounds, arsenates and fluorine compounds that are seldom used now and the sulfur which commonly used. The organic insecticides are synthetic chemicals that can comprise some of these largest numbers of pesticides available for use in today’s world. Lastly, the mode of action is the way on how these pesticides inactivates or kills a pest. The mode of action is always important in predicting whether the insecticide will be toxic to any unrelated species such as birds, mammals and fish.

Before using the insecticides, always remember to study the label on the product carefully and follow all the tag directions including the maximum number of applications allowed per day and the limits for use on children. Apply the repulsive sparingly only on the bare skin surfaces or on top of the clothing.

Remember not do use beneath the clothing and heavy application are unnecessary for effectiveness. Only repeat applications as necessary and do not let it get into your eyes. If the repellent do get into your eyes, rinse with water immediately as well as do not use it on open wounds or irritated skin and sunburned.

Always avoid breathing in the mists and never apply the sprays inside the tent. It should only be used in the airy areas. Always wash treated skin with water and soap when return back to indoors or when the protection is no longer needed. If suspected that the child is reacting to the insect repellent, stop using the product immediately and seek for medical attention.
