Weed Killer on Shabbat
Question
Is it permissible to use weed killer (for example, roundup) on Shabbat to destroy weeds)? In this case, the weeds are destroyed, not uprooted from the ground, and the weed clearing is done daily to maintain a healthy backyard. If the Rabbis could, please bring a source or responsa you find on this.
Answers
In looking around for sources, I came across the following interaction between yourself and M Bloch:
As such weeding is forbidden on Shabbat and spraying killer spray is a derivation of this. R Daniel Braude writes this constitutes sowing (Learn Shabbos in 3 minutes a day, p. 317). R Yosef Tzvi Rimon writes accordingly (Shabbat, vol. 2, p. 577).
