integrating of hilling up and cultivation with banded spraying in weed management in sugarcane fields
نویسندگان
چکیده
field experiments were conducted in amirkabir sugarcane agro-industry (khuzestan province, iran) farms to evaluate the efficacy of integrated chemical and mechanical methods in controlling weeds. experiments were carried out in a split plot-randomized complete blocks design with four replications. the main plot consisted of four mechanical treatments, namely: hilling up, sweep cultivator, disc cultivator vs. no tillage. the sub-plots included six herbicide treatments (tebuthioron (tebusan®) + ametryn, trifluxysulforon-sodium (envok®) + ametryn, ametryn-trifluxysulforon-sodium (krismat®) + 2, 4-d-mcpa, mesotrion (lumax®), ametryn + 2, 4-d-mcpa & control). evaluations consisted of a grading of weed control and sugarcane crop appearance, a measurement of weeds’ dry weight as well as crop’s yield, quality and quantitywise. results indicated that a hilling up treatment can merely act as a replacement for herbicide by 75% of control, whereas sweep cultivator and disc cultivator acted some measures of 15% and 5% of control respectively with the need for band spraying as a complement. mixtures of krismat® + (2, 4-d + mcpa), envok® + ametryn and lumax + cytogate® provided a good control of weeds, especially in combination with mechanical control measures, but they didn’t reflect any significant difference with ametryn + 2, 4-d as a standard control measure. all the herbicides, as well as their mixtures had significant differences with the untreated control. overall, it is concluded that mechanical control integrated with band spraying is a very cost effective method in sugarcane weed control.

AUTOMATED precision weed spot spraying in the sugarcane industry has potential to increase production while reducing herbicide usage. However, commercially-available technologies based on sensing of weed optical properties are typically restricted to detecting weeds on a soil background (i.e. detection of green on brown) and are not suited to detecting weeds among a growing crop. Machine vision...
