| While methyl parathion is more acutely toxic than the other two OPs, over time a child's chronic exposure to dimethoate and acephate can be just as dangerous. |
| Consider alternating synthetic pyrethroids such as permethrin or fenvalerate to organophosphates such as stirofos, dimethoate, or fenthion to carbamates such as methomyl. |
| In the past, the grass mites in most areas of the state have been controlled reasonably well with dimethoate, which is the least expensive product. |
| The major OP insecticides used include acephate, azinphos methyl, chlorpyrifos, dimethoate, disulfoton, fenamiphos, and phosmet. |
| Other insecticides have a narrower range of activity, such as dimethoate and Metasystox-R, which are toxic primarily to sucking pests such as aphids. |
