What are Insecticides?
Insecticides are chemicals and substances designed to kill or control insects. They came in various forms and worked through ingestion or systemic action to target and eliminate pests. There are several agriculture chemicals NZ that are very effective in vanishing pests from your farm.
These insecticides can come in various forms, like sprays, dust, granules, baits, or fumigants, and their application will also depend on their form.
Different Types of Insecticides and Their Working
Contact Insecticides
Contact insecticides are chemicals that kill insects immediately after coming into contact with their bodies. Contact insecticides are sprayed directly on the insects' surfaces. These insecticides can have immediate effects within minutes of exposure.
Examples: contact insecticides include pyrethroids and organophosphates. Pyrethroids work by targeting the nervous system of insects, and organophosphates work by inhibiting the enzyme acetylcholinesterase.
Working: These insect control products NZ are used for controlling pests in homes, gardens, and other areas where people and pets may be present.
Systemic Insecticides
As their name suggests, systemic insecticides work systematically, are absorbed by plants from their roots, and transfer gradually. Systemic insecticides are applied to the soil, sprayed on the leaves of plants, or injected into the trunk.
Examples: Examples of systemic insecticides include neonicotinoids and imidacloprid. These insecticides are effective in controlling a wide range of pests.
Working: These chemicals are taken through the plant’s vascular system, remain active for several weeks or months, and provide long-lasting protection against pests.
Fumigants
Fumigants are chemicals released into an enclosed space as a form of gas or vapor to quickly get rid of insects. This kind of insecticide is often used in enclosed areas like storage facilities, shipping containers, and grain elevators.
Examples: Phosphine and Methylbromide are the two most common insecticides NZ used for pest control.
Working: These chemicals work by directly attacking the metabolism of insects, causing suffocation and uneasiness. These fumigants are highly poisonous and harmful to both humans and animals.
Ingested Insecticides
Ingested insecticides are also known as stomach poisons. Ingested insecticides typically come in the form of baits, granules, or sprays. They contain active ingredients that are attractive to the target insects and cause them to consume the treated material.
Example: Examples of ingested insecticides include carbamates and organophosphates.
Working: Ingested insecticides directly target pests through the nervous system or metabolic processes, leading to their death.
How to Use Insecticides
While using the insecticides, you need to follow some instructions, and here is the list of steps and measures you need to follow:
