Abstract:
The growth of weeds in Andean crops in our region has an exponential increase due to poor agronomic management in the field by farmers, generating an increase in production costs; Likewise, weeds cover the crop. The objectives: Carry out agronomic management to control the weed Brassica rapa in the sowing of Andean crops and evaluate doses of plants with herbicidal principles for weed control in Andean crops. Sowing was carried out in October and November, first weeding 60 days after sowing. Three treatments were applied in different doses of wormwood, nettle and wormwood plus nettle in blocks, then hilling was carried out on the crop, weeds resistant to the treatments were counted. Results, at the field level a significant difference was found between treatments, the application of the natural herbicide product based on wormwood was positive, the cultural work contributed to the management of weeds, achieving good control and reduction of weeds in the crops. The treatment with a dose of wormwood plus nettle had a 90% control over the weeds with a dose of 500 ml of the herbicide, secondly, the dose of wormwood, a control of 80% was achieved with a dose of 500 ml of the herbicide and finally the dose Nettle had 70% control over weeds with doses of 500 ml of the herbicide. Concluding that the application of natural products based on native plants in the area had very acceptable weed control as indicated in the respective results. Managing to contribute to the sustainability of the environment, avoiding contamination of soil and aquatic bodies, replacing the application of chemical herbicide products.
