Application of oxyfluorfen and pendimethalin to control weeds on soybean plantation

Abstract

The appearance of weeds on crops has led to the significant loss of crop yield. Therefore, chemical control with herbicides has been an important tool for rapid and efficient weed management in crops. The objective of this study was to evaluate the effect of herbicides oxyfluorfen and pendimethalin against weeds on soybean plantation. This research employed Randomized Completely Block Design (RCBD) Factorial with 2 factors. The first factor was the type of herbicides: oxyfluorfen and pendimethalin. The second factor was herbicide doses: 0, 500, 1000, 1500 and 2000 g a.i ha-1, applied on soybean at 1 day after planting (DAP). The percentage of weed control, percentage of weed coverage, weed species, weed population, and weed dry weight were observed at 3, 5, 7 and 9 weeks after planting (WAP). The results revealed that different types and doses of herbicide applied has affected the percentage of weed control, percentage of weed coverage weed species and weed dry weight.
