Chlorthiophos
Description
Mode of action
Chlordiophos is a representative of the organophosphate chemical class, which functions primarily by targeting the nervous system of insects.
The active substance works by inhibiting the enzyme acetylcholinesterase, which is crucial for regulating nerve impulses in the insect's body.
The inhibition results in a continuous accumulation of the neurotransmitter acetylcholine, leading to nervous system paralysis and death.
Due to its chemical structure, chlordiophos provides strong contact and ingestion toxicity, making it highly effective for rapid pest eradication.
It exerts an immediate knockdown effect, significantly reducing pest pressure during critical growth stages of various agricultural crops.
What it targets
This group of substances is designed for controlling a broad spectrum of chewing and sucking insects that pose threats to global agriculture.
It is widely used to protect fruit trees, vegetables, and field crops against destructive populations of larvae and adult insect stages.
Chlordiophos is effective against various species of beetles, caterpillars, aphids, and other common agricultural and garden pests.
By providing long-term residual protection on plant surfaces, it helps prevent rapid re-infestation after the initial application.
- Various aphid species
- Beetles and their larvae
- Lepidoptera caterpillars
- Leafhoppers and similar pests
Rates and timing
The application rate for chlordiophos-based products must be strictly calculated based on the specific pest density and the crop's development stage.
Applications are most effective when applied during the early developmental stages of pests, ensuring better coverage and faster results.
Proper calibration of spraying equipment is essential to ensure a uniform distribution of the solution across the treated plant canopy.
Treatment should be avoided during peak heat or strong winds to ensure the product remains effective and to minimize potential drift risks.
Always follow the manufacturer's specific guidelines regarding the water volume per hectare and compatibility with other tank-mix partners.
Restrictions
Chlordiophos is considered toxic to mammals, beneficial insects, and aquatic organisms, necessitating extreme caution during handling and application.
Personal Protective Equipment (PPE) including gloves, eye protection, and specialized clothing must be worn at all times to prevent dermal exposure.
Strict adherence to pre-harvest intervals (PHI) is required to ensure that food products are safe for human consumption before reaching the market.
Avoid applying these substances during the flowering phase to protect pollinators like honeybees, which are highly sensitive to organophosphates.
Storage must be in cool, well-ventilated, and locked facilities to prevent unauthorized access and protect the environment from potential leakage.
