The effect of herbicides application with different doses to chemical control of weeds in garlic farms (Aliium sativum L.) and its impact on soil fauna
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 7
Abstract
In order to investigate the effect of different herbicides application with recommended doses and 25 % lower than that on weeds in garlic farms and its impact on soil fauna, an experiment through the completely randomized block design with three repetitions during cropping season 2012-2013 in the Maryanj village, the city of Hamadan was performed. The examined treatments included the use of herbicides Sethoxydim, Oxyfluorfen, Trifluralin, haloxyfop-R methyl ester, and Chlorthal-Dimethyl; all with recommended dosage respectively, 3, 1.5, 2.5, 1 liter and 8 kg per hectare and 25 % less than the recommended dose, respectively include 2.25, 1.12, 1.87, 0.75 liter and 6 kg/hectare, lack of control model (lack of weeding) and weed control model (weeding). The results showed that Oxyfluorfen herbicide with reduced dose caused remarkably reduction in a wide range of farm weeds. The only herbicide, which caused leaf scorch of garlic, was Sethoxydim which is not recommended in garlic agriculture. Oxyfluorfen devoted the most edaphic mites to itself and in terms of environmental preservation was considered the best treatment and had the less negative effects on soil fauna.
