ABSTRACT
Small yields are frequently the result of increased weed control difficulty in Zimbabwe's smallholder farming industry. Herbicides are typically the first line of defense against weeds; however, due to the possibility of weed resistance to herbicide management, different application rates must be tested on a regular basis. This study evaluated the herbicide Bateleur Gold, a factory premix of s-metolachlor and flumetsulam, to determine the rate of treatment that would effectively control weeds in Zea mays L. In this study, which used a randomized complete block design, slope was used as a blocking factor (RCBD). Flumetsulam (sulfonanilide) and s - metolachlor were used at different rates of 3.5L, 4.0L, 4.5L, and 5L, with no chemical used as a control. The herbicide was applied immediately after planting, while the soil was still moist, at five different herbicide treatments. The counts began the first week after planting and were completed over a two-week period. The yield of maize from various plots was eventually tallied in order to evaluate the herbicide effect. The findings revealed that there were more weeds in the first week, then a steady decline until the last week, and that species with broad leaves made up a larger proportion of the species than those with grasses. Furthermore, when compared to zero and low application rates, a high rate of herbicide treatment had an effect on weed population and crop output. This study demonstrated the herbicide's effectiveness as a pre-emergent substance and identified the optimal rate for weed control and higher yield. Additional research into the use of this substance in legumes should be conducted for the benefit of groundnut growers. Furthermore, while application rate 4.5L/ha does not provide statistically significant differences in the quantities of weed species when compared to application rate 5L/ha, additional research may be required to demonstrate this with greater certainty.
