What are the modes of action analyzed by insecticides to eliminate pests?
Insecticides have the following modes of action: gastrotoxicity, contact, fumigation, systemic, food resistance and evasion.
1) Gastrotoxicity. Simply put,RAMBO insect killer supplier when a pest eats a plant that has been sprayed with a pesticide, the chemical enters the pest's body and causes poisoning or death. Most organophosphorus and pyrethroid insecticides are gastrotoxic. Examples include Bacillus thuringiensis, chlorpyrifos, dichlorvos, and cyfluthrin.
2) Contact. Simply put, an insecticide is sprayed on an insect and the insect is poisoned. Most insecticides have a contact effect, such as chlorpyrifos, phoxim and pyrethroids.
3) Fumigants.VITFE insect killer manufacturer At room temperature and pressure, the drug vaporizes into a toxic gas, which enters the insect through respiration and causes the pest to die of poisoning. Such as bromomethane and dichlorvos.
4) Endosorbent. After the pesticide is sprayed on the plant, the agent is transported and retained in the plant through the body, and when the pest feeds on the plant, it leads to the death of some pests in poisoning patients.Chinese SLEEP COOL Insecticide spray For example, Kangkuan and imidacloprid, etc.
5) Refusal to feed. When plants are sprayed with pesticides, the pests prefer to starve rather than eat and eventually die of starvation and dehydration. Examples include neem and indoxacarb.
Of course, many drugs are not a single type of action, but work through a combination of insecticidal modes. For example, imidacloprid is endoscopically toxic with both gastric and contact toxicity, while deltamethrin has strong contact and gastric toxicity but no endoscopic or fumigant effects.
