1 | Rotate chemicals with a different mode-of-action group number, and do not use products with the same mode-of-action group number more than twice per season to help prevent development of resistance. For example, the organophosphates have a group number of 1B; chemicals with a 1B group number should be alternated with chemicals that have a group number other than 1B. Mode-of-action group numbers are assigned by IRAC (Insecticide Resistance Action Committee). |
2 | Selectivity: Broad means it affects most groups of insects and mites; narrow means it affects only a few specific groups. |
3 | Generally, toxicities are to western predatory mite, Galendromus occidentalis. |
4 | Toxicities are averages of reported effects and should be used only as a general guide. Actual toxicity of a specific chemical depends on the species of predator or parasite, environmental conditions, and application rate. |
5 | Ratings are as follows: I–Do not apply or allow to drift to plants that are flowering; II–Do not apply or allow to drift to plants that are flowering, except when the application is made between sunset and midnight if allowed by the pesticide label and regulations; III–No bee precaution, except when required by the pesticide label or regulations. For more information, see Bee Precaution Pesticide Ratings. |
6 | Duration: Short means hours to days; moderate means days to 2 weeks; and long means many weeks or months. |
7 | May cause flare-ups of spider mite numbers. |
8 | Acute toxicity low but reproductive capacity is impacted. |
9 | Toxic against some natural enemies (predatory thrips, syrphid fly larva, beetles) when sprayed and 5 to 7 days after, especially for syrphid fly larvae. |
10 | Residual is moderate if solution is between pH of 7 to 8. |
