Pirimicarb is a fast acting insecticide rapidly absorbed by the target aphid. I have not researched anything on this topic, but I'm curious. Is high dose primicarb effective against thrips?
Primicarb (pirimicarb) is a selective carbamate pesticide that works against aphids by blocking acetylcholinesterase; however, because aphids and thrips have different body structures and neurological systems, it cannot control thrips. Specific management techniques are needed for thrips; harmless substitutes such as insecticidal soaps and oils, as well as somewhat toxic but effective thrip-fighting alternatives like spinosad and abamectin, are recommended. In integrated pest management (IPM), biological controls, such as predatory insects (Orius spp., Amblyseius spp.), are crucial because they combine chemical treatments with biological and cultural methods to minimize resistance and sustainably control thrip populations.
High-dose pirimicarb, an anticholinesterase insecticide, is not typically recommended against thrips. Pirimicarb is primarily used to control aphids due to its specific mode of action targeting aphid pests only rather than a broad range of pests.
