| dc.description.abstract | C. rotundus L. has been described as the world's most noxious and persistent colony forming weed, seriously impacting agro-ecosystems in multiple regions of the globe. Th extensive underground system is a key feature in the success of this species, and a major obstacle to its effective control. An experiment was conducted from march to June 2019 at the screen house of Crop protection Division, Philippine Rice Research Institute, Maligaya, Science City of Muñoz, Nueva Ecija to (a) determine the responses of the three ecotypes of C. rotundus L. to different herbicides and (b) determine the best herbicide that can control the growth and reproduction of lowland ecotype C. rotundus L. Tubers of C. rotundus L. in irrigated rice field; rain fed rice field and rice onion field were collected in La Purisima, Aliaga; Mapangpang, Lupao; and Abar 2nd , San Jose City, respectively then pre-germinated to Crop Protection Division, PhilRice. The experiment was established on Randomized Complete Block Design 3 replicate having untreated, Pendimethaline, Pyribenzoxim + cyhalofop butyl, Bispyribac sodium, MCPA and 2,4-D Amine salt as treatment and Abar 2nd, San Jose City, Mapangpang, Lupao and La Purisima, Aliaga as the ecotype factor. Results showed that Pendimethaline was not effective to control the C. rotundus L. while Bispyribac sodium, MCPA and 2,4-D Amine salt effectively control the different ecotype of C. rotundus L. | |
