Organophosphorus pesticides are common pesticide products with diverse brands and uneven quality. Faced with so many pesticides, how should we choose? What are organophosphorus pesticides? How to use organophosphorus pesticides? Let's take a look at how to use organophosphorus pesticides below!
What kinds of organophosphorus pesticides are included?
Organophosphorus pesticides are currently the most produced and used type of pesticides in our country, accounting for a large proportion of occupational hazards caused by pesticides. Most of the organophosphorus pesticides produced in our country are insecticides, such as parathion, endophosphorus, malathion, digo, trichlorfon, dichlorfon, etc.; some varieties such as rice plague net, Keshan powder, etc. can be used as fungicides. In recent years, some rodenticides, nematicides, herbicides, defoliants, sterile agents, growth regulators, etc. have been synthesized.
The most common organophosphorus pesticides are: trichlorfon, dichlorvos, dioxate, malathion, phoxim, chlorpyrifos
According to the toxicity of organophosphorus pesticides, they are divided into three categories:
1. Highly toxic:phthalate, internal phosphorus absorption, parathion, cotton abundance, oxidation diethyl;
2. High toxicity categories: methyl parathion, dimethylthionate, dichlorvos, imidophos;
3. Low toxicity: trichlorfon, diethyl, thiophosphorus chloride, ethyl rice powder, etc.
Most organophosphorus pesticides are easily decomposed in alkaline solutions and lose their virulence; only trichlorfon is easily soluble in water, and after contact with alkaline solutions, it becomes more toxic dichlorfin. Phosphorus (1059), parathion (1605), phosphamion (3911),malathion(4049), dimethyl, etc. are oxidized, and their virulence is enhanced. Dibromophosphorus quickly loses bromine when it encounters reducing substances such as metals and sulfur-containing hydrides, forming dichlorvos with greater virulence.
Precautions for the use of organophosphorus pesticides
1. Strengthen the management of pesticides, establish rules and regulations, and publicize the knowledge of pesticides. It should be kept by a special person. It should be properly stored at home, and family members, especially children, should be educated not to move.
2. It is forbidden to use highly toxic pesticides to kill lice mosquitoes and flies, and it is forbidden to spray on the human body or clothing. Those who use pesticides should wear long boots, long-sleeved clothes, hats and masks, change clothes after use, and wash the skin thoroughly.
3. It is best for breastfeeding women to avoid exposure to pesticides.
4. Put food or clothing in bags with banned pesticides.
5. Fasting livestock and poultry poisoned by pesticides.
6. Suspicious patients should be immediately sent to the hospital for treatment.
