Talstar applied directly to Arabidopsis foliage eradicates aphids in one or two applications. This chemical seems to have little effect on the plants, but it can cause substantial damage to some other plants such as alfalfa, so should be used with care around other plant species. Resmethrin aerosol is effective against these, as is the application of Gnatrol bacterial solution to the roots as a supplement. These can be used together. Avid, applied weekly, is very useful.
Orthene aerosol is also useful for mites.
The application of Resmethrin aerosol with Orthene is effective against a number of other pests. An important aspect of insect control is detection and identification before populations multiply. Fresh traps should be placed in greenhouse rooms frequently and monitored continuously. Always identify a pest before embarking on treatment. Many predator species are currently marketed for control of some of the above pests.
