Rice will be fit, because farmers have HIFIT
C. difformis is a sedge which is known as the world’s worst weeds. being a problem especially in rice, is native to the tropics of the Old World, but is spreading well outside. It is a dominant weed in direct-seeded rice when it occurs in high plant densities; forms dense mats of vegetation in the young crop and can cause rice yield losses of 12-50%. This weed may account for 60-70% of the total biomass of the rice field. It has a relatively short generation period of as little as 4 to 6 weeks from seed to seed. It varies in height from 6 to 80 cm. The stems are smooth, triangular, slightly winged and 0.7-3.0 mm thick. The roots are numerous, fibrous and reddish. The leaves are smooth, flat, linear, 5-25 cm long or often two-thirds of the plant height, 2-6 mm wide, sometimes reduced to sheaths. Sheaths are tubular, united, green to reddish-brown and without leaf blades at the base.
The inflorescence consists of dense, globose, umbellate heads, simple or compound, 5-15 mm in diameter, with 10-60 stellately spreading spikelets. The inflorescence is rather loose, simple or compound, subtended by 1-4 leaf-like bracts, one of which can be up to 25 cm long. The umbel rays a
re 1-5 cm long, some long and some long peduncled. Spikelets are linear to oblong-linear, compressed but slightly swollen, obtuse, 2.5-8 mm long, 0.8-1.25 mm wide, 6-30 flowered. Glumes are 0.6-0.8 mm long, obovate, pale-yellowish to dark reddish-brown with yellow or white margins and a green midrib ending in a short mucro. Stamens 1-2. Style 3-branched. Achenes are 0.6-0.8 mm long and 0.3-0.4 mm wide, triangular, obovate-elliptic, yellowish-brown or pale-brown, minutely papillose.
As we know that it is a widespread and serious weed of paddy rice. It is important because it produces abundant seed and rapidly becomes a dominant weed in the fields. Producing abundant plants per unit area, the plant form dense and solid mats of vegetation in the young rice crop. This weed appears to be more of a competitor for water and nutrients than for light. The ability of the plant to complete a vegetative and reproductive cycle within a month or so makes it especially competitive in a crop which requires at least 90 or more days to reach maturity.
C. difformis is susceptible to many of the usual methods of weed control in rice crop. These include hand-pulling, manual and mechanical tillage and trampling in puddled fields. But these all methods are costly. HPM India’s leading agrochemical company makes cost effective and easy to use products for farmers. HPM has appointed a special managment team that looks into farming mechanism by visiting farmers personally , comprehending different needs of farmers. The company’s this act as an evenue of producing products according to crops and their needs.
HPM’s Hifit is a best solution for C. difformis. It is a broad spectrum selective pre-emergence to early post emergence Rice herbicide. It exhibits highly efficient control of a variety of weeds like annual grasses, sedges and broad leaved weeds. It controls weeds by inhibiting its growth and reducing the cell division. No adverse effect like stunting or yellowing of crop, rather gives greening effect to the crop.
