Abstract
Figures and Tables
Fig. 1
Pesticide classes and the ratio of suicide completion to suicide attempts (%) in each category, between 2011 and 2014. Combined pesticides*: two active ingredients in a pesticide formulation, or two or three active ingredients in more than two different pesticides. In general, pesticide formulations include various kinds of surfactants as an emulsifier. However, in some instances, the surfactant** is sold separately. For details, please see the "Discussion".

Change in the annual number of suicide attempts in each pesticide category after the PQ ban in 2012. Note that the annual attempt numbers decreased dramatically after the 2012 PQ ban in the herbicide category, where no significant change was observed in the other pesticide categories. The "other group" comprised of surfactant, warfarin (rodenticide), mite growth inhibitor (acaricide), and aluminum phosphide (fumigant). For the "combined" category, note the "Results" section in the manuscript.

Fig. 3
Change in the annual number of total suicide, suicide attempts with PQ, and PQ fatality. PQ attempts = suicide attempts using PQ ingestion. PQ fatality (%) = suicide completion using PQ versus attempts using PQ. Note a marked decrease in the annual number of both people attempting suicide with total herbicides and with PQ, (P < 0.001). The annual PQ fatality was between around 60%-70%.
