Integrated Use of 2,4-D, Metribuzin, and Pyrazosulfuron-Ethyl (UPH 114b) for Managing Weeds and Improving Sugarcane Yield in Subtropical India
A field experiment was conducted with eight treatments of weed management involving integrated and sole applications of 2,4-D, metribuzin, and pyrazosulfuron-ethyl along with weed-free and weedy check practices. The experimental treatments were replicated three times in a randomized block design. Applying integrated product of 2,4-D, metribuzin, and pyrazosulfuron-ethyl effectively managed the grassy (Cynodon dactylon, Eleusine indica, Echinochloa crusgalli, and Digitaria spp.) and broad-leaved weeds (Trianthema monogyna,Chenopodium album, Anagallis arvensis, Melilotus alba, Parthenium hysterophorus, and Bidens frondosa). The higher weed density (124.7 per m2) in weedy check plots was recorded during the first cropping season than 2nd cropping season (118.22/m2). Total weed dry weight was also significantly reduced at the lowest level (43.39 g/m2 during 2019–2020 and 75.70 g/m2 during 2020–2021) with the application of integrated product of 2,4-D, metribuzin, and pyrazosulfuron-ethyl @ 3200 g ai/ha. However, the weed control efficiency (77.57% and 55.59% during 2019–2020 and 2020–2021, respectively) recorded with application of similar herbicide @ 2400 g ai/ha was found at par with its application @3200 g ai/ha. The highest soil organic carbon content (19.90 Mg/ha) was recorded after sugarcane harvest in weedy check plots. The weed management through application of integrated product of 2,4-D, metribuzin, and pyrazosulfuron-ethyl @ 2400 g ai/ha could improve the sugarcane yield by 36.76% (101 tonnes/ha) over the weedy check plots. Increasing dose of the product @3200 g ai/ha could not increase the sugarcane and sugar yields up to significant level. Among all other herbicides treatments (single application) or integrated manner, application of 2,4-D, metribuzin, and pyrazosulfuron-ethyl @2400 g ai/ha also increased sugar yield by 45.12% (11.085 tonnes/ha) over the weedy check plots. The phytotoxicity of the new herbicide product of 2,4-D, metribuzin, and pyrazosulfuron-ethyl could not be recorded in subsequent wheat crops tested up to 4800 g ai/ha.
期刊介绍：
The journal Sugar Tech is planned with every aim and objectives to provide a high-profile and updated research publications, comments and reviews on the most innovative, original and rigorous development in agriculture technologies for better crop improvement and production of sugar crops (sugarcane, sugar beet, sweet sorghum, Stevia, palm sugar, etc), sugar processing, bioethanol production, bioenergy, value addition and by-products. Inter-disciplinary studies of fundamental problems on the subjects are also given high priority. Thus, in addition to its full length and short papers on original research, the journal also covers regular feature articles, reviews, comments, scientific correspondence, etc.
