Is the pesticide sprayed by the green belt toxic?

The liquid medicine sprayed by the green belt adopts ecological pesticides and is non-toxic. But no matter what pesticides, even pyrethroids in mosquito-repellent incense are toxic, but some are more toxic and some are less toxic. Generally non-toxic, it can be regarded as non-toxic. Although it stinks, it will not do harm to people's health. However, it is recommended to close the doors and windows when spraying medicine outdoors, and do not go to the spraying area for activities.

Pesticides sprayed for killing insects and sterilizing plants in green belts can be divided into biological agents and chemical agents. Greening biological agents are basically harmless to human body; At present, some highly toxic chemicals such as methamidophos and omethoate have been banned, so they should be harmless.

Once toxic chemicals are sprayed, atomized particles will be inhaled into human lungs, causing chronic or acute poisoning. Toxic pesticides will irritate human skin if sprayed on residents' clothes and quilts. Therefore, when spraying pesticides in public places and residential areas, it is generally advocated to use biological pesticides and bionic chemical pesticides. Sometimes pesticides such as dimethoate or malathion may be used, which has a strong smell, but it is not too harmful to people. The general pesticide residue odor can be dispersed in 1-2 days.

It is understood that most of the city's green belts use non-toxic pesticides, but there will also be cases in which individual community greening is entrusted to green maintenance units for management or contracted to individuals for maintenance. Individual contractors or individuals will choose some toxic pesticides with lower prices in order to save money and make profits. It is hoped that the property management company will strictly prevent toxic pesticides from entering the green belt of residential quarters and spraying in public places. Property and residents can consult the local urban greening management department if they have any questions about the pesticides used.

The plants in the green belt are mainly trees, shrubs, cool-season lawns and herbal flowers, so it is inevitable to adopt mosquito repellent control during maintenance. General trees are mainly used as street trees in street greening; The choice of shrubs can block the line of sight and reduce the noise. Most cities in the north mainly choose cool-season lawns as ground cover plants; When choosing herbaceous flowers, open-field flowers, mainly perennial flowers, are skillfully matched with trees and shrubs.
