Prevention and control

L. anagallis may be controlled manually and with herbicides. Bensulfuron-methyl gave good control of L. anagallis for up to 20 days after sowing (Chiang and Leu, 1987). While Lindernia species are normally controlled by sulfonylurea herbicides, resistance to this group of herbicides has now been observed in Japan, in L. micrantha, L. dubia, L. pyxidara and L. sessiliflora (Itoh and Guangxi Wang, 1997).

Impact

L. anagallis is a weed of relatively minor importance, occurring in transplanted rice in India, Indonesia and Thailand, in upland rice in India, Indonesia and the Philippines, and in wet-seeded rice (sprouted seeds sown on puddled soil) in Thailand. It has also been reported as a weed of lowland rice in Bangladesh and Sri Lanka, and of rice in Nepal and Vietnam (Moody, 1989). L. anagallis occurs in paddy fields of the central and northern parts of Taiwan and in winter catch-cropping fields in central Taiwan (Anon., 1964).

Horng (1976) reported that annual weeds had decreased greatly in paddy fields to which herbicides had been continually applied; L. anagallis, once very important, was now much less prevalent. However, it is a potential problem weed in transplanted and wet-seeded rice in Nueva Ecija province, Philippines (Pablico and Moody, 1986).
