An</p><p>experiment was established on June 13, 1999, and the second</p><p>on June 9, 2000 with rice cv Milagro Filipino at 100 kg/ha. A</p><p>randomized complete block design with eight treatments and</p><p>the second six with four replication each one was established.</p><p>In 1999, weed control was evaluated at 15, 30 and 105 days</p><p>after application (DAA) and in 2000, at 15, 30 and 45 DAA.</p><p>In both experiments, toxicity was evaluated at 15 and 30</p><p>DAA. The main weed species were junglerice [Echinochloa</p><p>colona (L.) Link.], flatsedge (Cyperus iria L.) and Southern</p><p>crabgrass [Digitaria ciliaris (Retz.) Koel]. Bispyribacsodium</p><p>affected only emerged plants; this herbicide</p><p>efficiently controlled flatsedge at 15 g/ha, junglerice at 22</p><p>g/ha and Southern crabgrass was only partially controlled.</p><p>When bispyribac-sodium was mixed with clomazone or</p><p>thiobencarb, grass control was increased and a residual</p><p>herbicide effect was obtained. Bispyribac-sodium was highly</p><p>selective to rice.</p>}, number={1}, journal={Agronomía Mesoamericana}, author={Esqueda-Esquivel, Valentín Alberto and Rosales, Enrique}, year={2004}, month={Mar.}, pages={09–15} }
